⚡ Overview

Date Plan / release Features flipped Notes
2026-06-18 v5.5.0 — V5-3: storage cutover: kernel → device-local V5-3: vault backend deleted from harness_memory.py kernel; harness_state_dir / read_state_file / write_state_file always device-local; phase_recall always ""; resolve_documenter_context always None; vault_path() raises StorageBackendNotInstalledError when storage.backend=vault + no vault ($MEMORY_VAULT_PATH stays graceful-skip). personal-private/ → personal/ group rename shipped in lockstep. (ADR 0018) 7 commits (v5.4.0..v5.5.0); 1170 unit tests 0 failures; 20/20 check-all.sh; solo harness MINOR
2026-06-17 v5.4.0 — V5-9 memory MCP server V5-9: scripts/memory_mcp_server.py (singleton streamable-HTTP daemon at 127.0.0.1:7821) + four MCP tools (memory_search / memory_recall / memory_append / memory_forget) + bearer-token + Origin-validation security + scripts/memory_mcp_stdio_shim.py (Claude Desktop stdio shim) + scripts/memory_mcp_doctor.py (4 health checks) + install.sh --mcp-server + launchd plist + host configs for Claude Code / Cursor / Goose / Claude Desktop. (ADR 0017) 11 commits (v5.3.0..v5.4.0); contract tests + 13 doctor unit tests; solo harness MINOR
2026-06-16 v5.3.0 — V5-11: team-coordinator persona V5-11: personas/team-coordinator.md (first real composed persona) + scripts/plan_graph.py + scripts/standup.py + scripts/readiness.py + scripts/merge_order.py — the coordinator capability set. requires: [queue_status_lite], enhances: [developer-workflows, github-projects]. 1 commit (7966ac3); 62 fixture-backed tests; check-personas exits 0; solo harness MINOR
2026-06-16 v5.2.0 — V5-8 capability-discovery resolver + V5-12 persona tier V5-8: scripts/capability_resolver.py + scripts/capability_version_match.py + agentm capability CLI shim — the enhances: runtime (ADR 0015). V5-12: personas/rememberer.md + scripts/check-personas.py + check-personas CI gate — the kind: persona third tier (ADR 0016). 6 commits (v5.1.0..v5.2.0); 72 unit tests (32 resolver + 40 version-match); check-capability-resolver-one-way + check-personas gates green; solo harness MINOR, no crickets pairing
2026-06-13 v5.0.1 — V5-1 follow-on: non-UTF-8 config readers honor their contract (harness-only PATCH) Correctness follow-on to the V5-1 storage seam. The four config readers (backend_selection.py::_configured_backend, harness_memory.py::_read_config_vault_path + _read_config_state_mode, agentm_config.py::_read_config) caught (json.JSONDecodeError, OSError) but not UnicodeDecodeError — a ValueError subclass — so a non-UTF-8 config (realistic trigger: a Windows UTF-16/BOM "Save As") leaked an uncaught decode error past each reader's documented contract: the fail-loud resolver crashed instead of raising StorageSelectionError, and the three graceful readers crashed instead of returning None. All four now also catch UnicodeDecodeError; five regression tests pin the contract (incl. the doctor preview reporting [FAIL] not crashing). Found by an adversarial review of the V5-1 part-5 selection code. 2 commits (v5.0.0..v5.0.1: the fix 50cde80 + this release commit); solo harness PATCH, no crickets pairing; no new ADR — correctness fix within the ADR 0013 fail-loud contract
2026-06-13 v5.0.0 — Agent M V5: the memory↔storage seam + the dev-loop unbundling (MAJOR) The storage-agnostic memory OS arrives, and the vendored dev loop leaves. Five roadmap arcs land together. V5-1 — the memory↔storage seam (the headline): a verb interface (resolve/read/write/list/exists/info/mkdir) handing back an opaque Locator (never a Path, AST-gate-enforced); a named-backend registry (resolve-as-absent); a device-local plain-markdown backend (~/.agentm/memory/); a backend-agnostic conformance suite; the existing GDrive vault wrapped behind the seam (whole-file conflict-strategy name, never-orphan invariant); and selection + fail-loud — a storage.backend config key + resolver (fresh→device-local; vault_path→vault), a StorageSelectionError that refuses an unregistered/misconfigured backend rather than silently demoting (incl. corrupt-config hardening), and a doctor storage preview byte-identical to the guard. V5-0 — vault-write protocol: vault_lock mutex + content-hash CAS + atomic_write routing + a four-marker-family conflict-janitor (incl. DriveFS lost_and_found). V5-4 — process seam: a read-only memory↔process client seam + a one-way import-direction gate. V5-10 — named plans: a named-plan resolver + binding (loud-error guard), queue_status_lite read-only multi-plan dashboard, named-plan-aware session-start hooks + doctor, a naming gate, and a resolve-active-plan CLI bridge. The 2 BREAKING changes: docs taxonomy converged to seven sections; migrate-to-diataxis + the dev-loop primitives (phase commands + review sub-agents) + the vendored documenter/diataxis-author copies were retired from agentm — now provided by crickets plugins with graceful-skip. Two new seam gates (check-storage-seam-no-path-leak, check-process-seam-import-direction). 76 commits (v4.15.0..v5.0.0); new ADR 0013 (storage-seam fail-loud selection) joins ADR 0011 (V5 unbundling) + ADR 0012 (vault-write protocol) shipped earlier in the wave; the two BREAKING refactor(harness)!: commits (5e85b6b retire migrate-to-diataxis; 3d2b328 slim the dev-loop) drove the MAJOR bump; per-/work documenter passes flipped each arc's pages pending → implemented during the wave — this release sweep adds the reconciliation entry + sidebar nav + the storage-seam ADR. Named-Plans stays pending on a single remaining dependency (the .harness/active-plan marker writer, a worktree-spawn helper not in this range) — see its page
2026-05-25 v3.1.0 — Repo rename agentic-harness → agentm (paired with crickets v1.1.0) Repo rename: GitHub repo for this project is now alexherrero/agentm (was alexherrero/agentic-harness); local sibling-clone path convention changes to ~/Antigravity/agentm/. Brand-name (Agent M) was always the operator-facing label; rename brings URL slug + clone path in line with the brand. Sibling repo also renamed: alexherrero/agent-toolkit → alexherrero/crickets. All cross-references across both repos swept (~595 occurrences across ~112 files in agentm; ~642 occurrences across ~142 files in crickets; vault entries also swept ~43 files/157 occurrences). GitHub installs HTTP redirects from old URLs to new automatically; existing clones/links keep working. No behavior changes — pure rename + cross-reference sweep; no API surface or installer behavior changes. 1 commit (v3.0.1..v3.1.0); paired with crickets v1.1.0 which does the toolkit-side equivalent sweep; 9th consecutive paired-release pair; closes plan #15 task 11 (the final closing task of the README refresh plan); operator-local ~/.claude/CLAUDE.md imports + sibling dev-setup repo + alexherrero/alexherrero profile README all updated for cross-repo consistency
2026-05-24 v3.0.1 — Agent M logo hero + brand asset set (harness-only PATCH) First visual brand iteration — adds the Agent M logo asset set (~41 files across assets/agent-m/ + assets/m-monogram/ + assets/index.html brand-preview page; designed in Claude.ai Artifacts with brand palette --ink: #0a0a0a + --paper: #f4efe6 and typography Inter Tight + JetBrains Mono) and refreshes README.md with a centered logo hero (agent-m-clean-transparent-512.png at displayed 256px) + italic tagline ("Persistent agentic memory + phase-gated engineering harness.") + reorganized badge layout into two centered blocks per the new personal-comms-style public-surface conventions. No behavior changes. Solo harness PATCH — not paired with Crickets; Crickets assets land separately when designed. Plan #15 task 1 close-out (Wave 1 of README refresh). 2 commits (v3.0.0..v3.0.1); first visual asset commit since repo inception; establishes assets/ as the brand-asset convention going forward
2026-05-24 v3.0.0 — Agent M V3 close-out (paired with toolkit v1.0.0 — Crickets 1.0) Agent M V3 ships — harness version now matches the memory implementation V-versioning (V3 = merged-Obsidian-and-GDrive vault with auto-recall in every harness phase + controlled write under the permeable A3 boundary). System renamed in operator-facing prose: Agent M (this repo + Crickets sibling toolkit + AgentMemory vault folder, together) + Crickets (the toolkit — noisy-cricket MiB ref; small primitives that punch above their weight). README rewrites (both repos) lead with brand framing; harness wiki Home rebranded; new HLD at crickets/wiki/explanation/designs/agent-memory-evolution.md walks V1→V4 evolution; new V3 retrospective at crickets/wiki/explanation/v3-retrospective.md covers what shipped / what we learned / what's deferred. Roadmap split into slim ROADMAP.md (non-V4 backlog) + new ROADMAP-AgentMemoryV4.md (9 V4-line items) + full pre-split snapshot at ROADMAP.archive.20260523-v3-complete.md (all operator-local; .harness/ is gitignored). Folds in ROADMAP items #12 (retrospective) + #27 (Agent M evolution design doc) + #31 (META split-the-roadmap). 2 commits (v2.6.1..v3.0.0); paired with crickets v1.0.0 which ships Crickets 1.0 (stable public API surface commitment: manifest schema + installer flags + bundles namespace + 11 customization kinds + per-host paths) + 4 commits on toolkit side (V3 retrospective + Agent M HLD + cross-ref fix + Crickets README/Home rewrite); closes ROADMAP items #12/#27/#31; 8th consecutive paired-release pair + first MAJOR-MAJOR pair; harness V-versioning now matches memory implementation V-versioning explicitly
2026-05-23 v2.6.1 — quality-gates bundle (paired with toolkit v0.13.0) One-command install for the 4 base operator-control + verification primitives most /work sessions want: evaluator + kill-switch + steer + commit-on-stop + evidence-tracker. Paired-doc-only on harness side; substance ships in toolkit. Closes the "I forgot to install commit-on-stop and lost an hour" failure mode by offering --bundle quality-gates as a single adoption command. Bundle uses sibling-reference dispatch (bundle dir is just bundle.md; installer resolves to standalone primitives at install time) — net -1992 lines vs. the originally-planned COPY pattern after operator pushback mid-plan. 1 commit (v2.6.0..v2.6.1); paired with crickets v0.13.0 which does the 6-commit sweep across plan #10 tasks 1-4 (bundle scaffold + sibling-reference pivot + smoke tests + Windows fixes + how-to + ADR 0010 + release); decision rationale + 2 locked design calls Q1-Q2 + 4 load-bearing assumptions in toolkit-side ADR 0010; closes ROADMAP item #10; 7th consecutive paired-release pair; 2 cross-platform Python gotchas caught + fixed mid-plan (pwsh mkdir; inline-Python UTF-8)
2026-05-23 v2.6.0 — Evidence-tracking for /work (paired with toolkit v0.12.0) Default-FAIL evidence enforcement on /work: every PLAN.md task starts with evidence-met=false; the agent must demonstrably READ relevant spec/test/evidence files (via the Read tool, observed by a new PreToolUse hook) before a Write/Edit that flips [ ] → [x] is allowed. Hook blocks (exit 2) with helpful stderr + 3 recovery paths. Harness-side ships the /work §5b spec amendment + templates/PLAN.md task-body convention update + Completed-Features row. Toolkit-side ships the substantive 4th base hook (~720-line stdlib-only Python helper + 61 unit tests + .sh/.ps1 entries + installer .py-sidecar extension). 2 commits (v2.5.0..v2.6.0); paired with crickets v0.12.0 which does the 9-commit substantive sweep across plan #9 tasks 1-6 + drift-cleanup; decision rationale + 3 locked design calls Q1-Q3 in toolkit-side ADR 0009; closes ROADMAP item #9; 6th consecutive paired-release pair + second non-doc-only on the harness side (after v2.5.0); 2 in-flight scope expansions caught + fixed mid-plan (installer .py-sidecar pattern; toolkit baseline drift 21→0 structural errors)
2026-05-22 v2.5.0 — Auto-context into harness phases (paired with toolkit v0.11.1) First non-doc-only paired pair in the run — harness ships real new phase behavior across all 5 phases + bugfix pipeline. New scripts/harness_memory.py dispatcher (4 sub-commands: recall / offer-save / plan-done-promotion / available) called from amended phase specs at natural boundaries. Self-modulating offer-save (agent-supplied --confidence ≥ HARNESS_AUTO_SAVE_CONFIDENCE_THRESHOLD → silent save with stderr notice; below threshold → preview-and-ask prompt). Shared .harness/.promoted-progress-cursor between /work plan-done + /release tail-scan triggers means single-fire per plan-window. Graceful-skip when MemoryVault not installed (harness still runs unchanged). 9 commits (v2.4.3..v2.5.0); paired with crickets v0.11.1 which adds the cross-repo memory protocol doc (wiki-only PATCH); new ADR 0007 with 5 locked design calls (Q1–Q5: per-phase budgets / vault_project 3-tier auto-detect / graceful-skip / self-modulating ask / dual-trigger cursor-tracked promotion); 5 phase specs + 1 pipeline amended via sub-letter convention (§1b / §4c / §7b / §7c / §2b / §5b / §5c) preserving integer §-numbers + 4 wiki line-anchor updates; closes ROADMAP item #8; 5th consecutive paired-release pair but first non-doc-only in the run (harness MINOR bump justified by real new phase behavior)
2026-05-22 v2.4.3 — diataxis-author skill (paired with toolkit v0.11.0) New second-major-skill diataxis-author shipped in toolkit — one skill, five sub-commands (/diataxis author + check + repair + migrate + classify) covering the full Diátaxis-wiki lifecycle. Subsumes migrate-to-diataxis harness predecessor (deprecated). Harness-side is doc-only (Completed-Features + CHANGELOG + deprecation NOTE on predecessor); skill scripts + sub-agent + templates + how-to + ADR ship on toolkit side. 1 harness commit (deprecation NOTE d4d4adf) + 1 release commit; paired with crickets v0.11.0 which does the substantive 8-commit sweep across plan #13 parts 1-5 (scaffold + author-classify + check-repair + migrate-subsume + agentmemory-docs-release); decision rationale in toolkit-side ADR 0008; second real dogfood of plan #6's /design skill (after MemoryVault); 4th consecutive paired-release-as-documentation pair (v2.4.0/v2.4.1/v2.4.2/v2.4.3)
2026-05-22 v2.4.2 — MemoryVault Discovery + Mining (paired with toolkit v0.10.0) Discovery + mining additive layer: five new /memory sub-commands (index-skills / reflect corpus / discover-skills / adapt-skills / watchlist) turn the vault from a static curated store into a living surface. Personal-skills auto-indexer; historical-transcript-backlog mining with dry-run-default; cadence-checked internet skill-discovery scan (operator's 4-source whitelist); adapt-don't-import workflow with 6-rule Python rubric + GitHub metadata + trustworthiness signals + LLM sub-agent judgment; promote/dismiss/defer review surface. Adapt-don't-import is architecturally enforced via sub-agent write allowlist. Harness-side is doc-only (Completed-Features + CHANGELOG + ROADMAP move + PLAN archive). 1 commit (v2.4.1..v2.4.2); paired with crickets v0.10.0 which does the 8-commit substantive sweep across plan #7b tasks 1-7; decision rationale + 7 locked design calls in toolkit-side ADR 0007; closes ROADMAP item #7b (MemoryVault parent design fully shipped — both #7a + #7b roadmap items now Completed); paired-release-as-documentation pattern (continues from v2.4.0 + v2.4.1)
2026-05-20 v2.4.1 — Local-only embeddings (paired with toolkit v0.9.2) Embedding-mode collapse: Voyage/Anthropic API mode dropped from crickets's memory skill; local sentence-transformers is now the only production mode. Default model BAAI/bge-large-en-v1.5 (1024-d native; 384-d → 1024-d dim bump). Harness-side is doc-only (Completed-Features + CHANGELOG); embed.py + vec_index.py + install scripts refactor happens on toolkit side. 1 commit (v2.4.0..v2.4.1); paired with crickets v0.9.2 which does the 8-commit substantive sweep across plan #18 tasks 1-7 (embed.py refactor + vec_index.py rebuild + smoke install split + install scripts pip-install + ADR amendment + docs rewrite + this paired release); decision rationale in toolkit-side ADR 0001's 2026-05-20 amendment; plan #18 is the first mid-flight plan insertion in the personal-dev-env (inserted into the active queue during plan #7a part 5 execution; seed-pass resumes at task 6 after this release pair ships); paired-release-as-documentation pattern (continues from v2.4.0)
2026-05-17 v2.4.0 — Gemini-CLI host removal (paired with toolkit v0.9.0) Host-scope reduction: standalone Gemini CLI dropped from supported hosts across the personal-dev-env. Keeps Claude Code + Antigravity. Harness-side is doc-only (Completed-Features + CHANGELOG); customization sweep happens on toolkit side. 1 commit (v2.3.1..v2.4.0); paired with crickets v0.9.0 which does the substantive customization + installer + wiki + ADR sweep across 5 commits (e1b477e + 5af1a59 + b216043 + 13109fa + 7a4162f); decision rationale in toolkit-side ADR 0006; first host-scope reduction in personal-dev-env history; paired-release-as-documentation pattern (substantive change lives toolkit-side; harness still ships a paired MINOR for version-cadence readability)
2026-05-16 v2.3.1 — /plan external-review-handoff option (dogfood-driven patch) Additive: /plan phase spec §4b documents the external-review-handoff option (pre-handoff snapshot + transfer-context generation + handoff prompt + diff-on-resume + Accept/Iterate/Discard) as an alternative to inline iteration on long plans 1 commit (v2.3.0..v2.3.1); paired with crickets v0.8.1 which adds the same option to /design author + /design translate; shared transfer-context template lives toolkit-side; first cross-repo dogfood-driven amendment shipped as coordinated patch pair (surfaced during MemoryVault design-doc walk on 2026-05-15); design rationale in toolkit-side ADR 0004 amendment (2026-05-16)
2026-05-15 v2.3.0 — /release + /setup integration for crickets's /design skill Additive: /release §1b lifecycle hook auto-promotes queued plans + transitions design final → launched + surfaces launched published designs in wiki/Home.md; /setup §7 scaffolds wiki/explanation/designs/ landing dir; templates/wiki/explanation/designs/.gitkeep + README; EXTERNAL_CUSTOMIZATIONS extends with design; /work Step 11 ROADMAP-driven enhancement (universal) 2 commits (v2.2.0..v2.3.0); paired with crickets v0.8.0 which ships the /design skill with 3 sub-commands; no new harness ADR (the design decision lives in crickets ADR 0004); harness still functions standalone — §1b silent-skips when no design-doc origin signal
2026-05-14 v2.2.0 — /work + /release augmentable with crickets's base hooks Additive: /work + /release phase specs gain optional sections documenting kill-switch + steer + commit-on-stop dispatch from crickets (operator-precision hooks for long-running sessions); check-references.py EXTERNAL_CUSTOMIZATIONS extended with 3 new hook names 1 commit (v2.1.0..v2.2.0); paired with crickets v0.7.0 which ships the three hook customizations + first-class kind: hook installer support; no new harness ADR (the design decision lives in crickets ADR 0003); harness still functions standalone — both sections graceful-skip when toolkit absent
2026-05-13 v2.1.0 — /review augmentable with crickets's evaluator Additive: /review phase spec gains §3b documenting evaluator dispatch alongside adversarial-reviewer (complementary, not competing); check-references.py EXTERNAL_SKILLS → EXTERNAL_CUSTOMIZATIONS rename to cover cross-repo agent references 1 commit (v2.0.0..v2.1.0); paired with crickets v0.6.0 which ships the evaluator; no new harness ADR (the decision lives in crickets ADR 0002); harness still functions standalone — §3b graceful-skips when toolkit absent
2026-05-12 v2.0.0 — crickets repo split: dependabot-fixer + ship-release moved out BREAKING: two skills migrated to crickets; new shared lib/install/ byte-identical across repos; PII + lib-parity CI gates added 9 commits (v1.0.0..v2.0.0); new ADR 0006; paired with crickets v0.5.0; harness shared-skills narrow 4→2; cross-platform byte-identity work surfaced + fixed four real Mac/Windows bugs
2026-05-11 v1.0.0 — Three-adapter scope; Codex dropped; 1.0.0 commitment BREAKING: Codex adapter removed; true-sync --update semantics; firm-semver 1.0.0 floor 13 commits (v0.9.0..v1.0.0); new ADR 0005; ~1300 lines net removed; first major version; parity invariant simplified to three adapters
2026-04-23 v0.9.0 — Diátaxis documentation spec + /doctor skill Diátaxis rollout (ADR 0004, 7-task plan); migrate-to-diataxis skill; mode-aware documenter writes; /doctor skill for post-install verification 10 commits (v0.8.7..v0.9.0); new ADR 0004; two new shared skills; scripts/check-wiki.py shipped + flipped to --strict; wiki dogfood reshaped with git mv for blame
2026-04-21 v0.8.7 — GitHub Projects wiring + documenter end-to-end dogfood feat-gh-projects-integration (pending — gated on offer-cycle observation); feat-documenter-subagent (this sweep is the dogfood) 4 commits (801dbd7..HEAD), 23 files; new ADR 0003, new Feature page

2026-06-18 — v5.5.0: V5-3: storage cutover — kernel → device-local

Commit range: v5.4.0..v5.5.0 (7 commits). Release notes: v5.5.0. Solo harness MINOR — no crickets pairing.

V5-3 closes the engine-cutover deferral that ADR 0013 DC-6 and ADR 0011 both named as "a separate, later step beyond V5-1." Until V5-3, harness_memory.py still read and wrote phase state the old way — harness_state_dir might return a vault path, read_state_file / write_state_file might route to <vault>/_harness/, phase_recall assembled recall bundles from vault markdown, and resolve_documenter_context read projects/_global/wiki-style/ from the vault. V5-3 collapses all of that to device-local.

Three coordinated changes:

Delete the built-in vault backend from the kernel (8cb2b48). harness_state_dir(resolution) now always returns <project_root>/.harness/. read_state_file / write_state_file read and write only device-local files — the vault-routing tier and the one-warn-per-session-per-file deprecation path are deleted. phase_recall always returns "" (V5-9 MCP now provides context at the process boundary). resolve_documenter_context always returns None (callers already handled rc=1 gracefully). All five test_harness_memory.py tests that expected vault-routing behavior were updated in the same commit, honoring the V5-6 principle of relaxing by-name test expectations in lockstep with the kernel delete.

Make vault_path() fail-loud guard load-bearing (05e63d3). New StorageBackendNotInstalledError class in harness_memory.py. vault_path() raises it when storage.backend=vault is set in the install config but no vault path resolves — the guard fires at the choke point, on every call path, not only through select_backend(). The $MEMORY_VAULT_PATH env override remains a graceful-skip per-session escape hatch (DC-5 of ADR 0018): the guard fires on the durable config-file commitment only, not on a transient env override. Six TestVaultPathGuard tests pin the contract.

personal-private/ → personal/ group rename (053217b). The planned vault-area rename (ADR 0010 re-audit trigger #1) ships in lockstep: vault directory on-disk, _ALWAYS_LOAD_REL kernel constant, and all functional path references in the kernel + scripts tree — making the cutover atomic from the operator's perspective.

By the numbers: 1170 unit tests, 0 failures; 20/20 check-all.sh; +158 insertions / +908 deletions net (bulk of the deletions from removing vault-routing code and stale tests).

Related: ADR 0018 — the five-decision record for this cutover; ADR 0013 amendment — the two V5-3 negative-consequence bullets now marked resolved; ADR 0010 amendment — personal-private → personal rename noted.

2026-06-17 — v5.4.0: V5-9 — memory MCP server

Commit range: v5.3.0..v5.4.0 (11 commits on main). Release notes: v5.4.0. Solo harness MINOR — no crickets pairing.

What shipped

V5-9 wraps the memory engine as a local MCP server so every MCP-capable host on the machine can reach the vault through a single protocol surface.

Server skeleton and transport. scripts/memory_mcp_server.py — a FastMCP (>=3,<4) singleton daemon bound to 127.0.0.1:7821. Streamable-HTTP transport; one daemon, N Mcp-Session-Id sessions. All writes from all MCP hosts funnel through one process — the Phase-1 concurrent-write broker the V5-0 write protocol was staged to receive. A liveness probe at /health returns {"status": "ok"}.

Four MCP tools. memory_search (semantic similarity, paginated), memory_recall (budgeted phase-bundle), memory_append (idempotent write), memory_forget (soft-delete — never unlinks the backing file; status flip propagates safely under Drive sync). Tool names are snake_case, no dots — OpenAI-family host compatibility. An in-memory test client covers contract tests offline.

Writer routing. memory_recall fails loud on an unconfigured source; source resolution goes through V5-1 backend_selection (vault-primary) — never a hardcoded repo allowlist. The daemon is writer #2 alongside the CLI as writer #1.

Security. TokenVerifier ASGI middleware (bearer token via AGENTM_MCP_TOKEN env var); _OriginValidator ASGI middleware (unexpected Origin: header → 403, DNS-rebinding defense); path-traversal validation engine-side.

stdio shim. scripts/memory_mcp_stdio_shim.py — proxies stdio transport to the HTTP daemon for hosts that require it (Claude Desktop). The daemon stays the sole write-broker; the shim is a thin compatibility adaptor.

Operations. scripts/memory_mcp_doctor.py — four health checks (liveness, token_env, origin_guard, index_root_safe), 13 unit tests. scripts/com.agentm.memory-mcp-server.plist — launchd template (RunAtLoad + KeepAlive; binds the daemon at login). install.sh --mcp-server flag registers the plist. Host config snippets ship for Claude Code, Cursor, Goose, and Claude Desktop.

Two bug-fix commits in range. fix: exclude __pycache__ from lib-parity checksum and fix(V5-9): normalize lock-root path to POSIX before marker check (Windows backslash compatibility).

Why this shape

V5-0 built the write protocol as "Phase 1: single-writer CLI"; V5-9 is Phase 2: any MCP host is a second writer, and the singleton HTTP daemon is the broker that collapses that fan-out from N writers to one. DC-1 through DC-5 in ADR 0017 record the five load-bearing design calls: singleton streamable-HTTP over stdio (single-writer property), four snake_case tools (host compat), soft-delete as a hard acceptance criterion (synced-vault safety), loopback-first deferring the remote tier (homelab posture + scope), and FastMCP >=3,<4 with the official SDK named as fallback (OOtB bearer auth + in-memory test client; cheap to swap).

2026-06-16 — v5.3.0: V5-11: team-coordinator persona (first real composed persona)

Commit: 7966ac3 on main. Release notes: v5.3.0. Solo harness MINOR — no crickets pairing.

What shipped

personas/team-coordinator.md — the first persona with real composition. kind: persona, requires: [queue_status_lite], enhances: [developer-workflows, github-projects]. Passes check-personas (requires ⊆ substrate-native; no always-load).

Four stdlib-only scripts form the capability set — no model, no live vault:

  • scripts/plan_graph.py — shared map engine. Reads _harness/ (active plans + queued-plans/ subdir) and returns a list[PlanInfo]. Each PlanInfo carries slug, filename, status, tasks done/total, last_touched (from progress log), depends_on (YAML frontmatter), touches (YAML frontmatter), active (bool).
  • scripts/standup.py — derives worker_state per active plan: building (tasks remain, recent touch), mergeable (all tasks done), idle (no touch in >2h, tasks remain). Returns a list[WorkerRow].
  • scripts/readiness.py — two-stage: (1) dep readiness (queued plan ready when all depends_on done); (2) safe-to-run-together overlap check via touches: glob lists. Plans without touches: are loudly degraded — never silently included. Returns {ready, safe_together, held_back, degrade_warnings}.
  • scripts/merge_order.py — topo-sort by depends_on edges + smallest-git-diff tie-break (git diff --stat) + alphabetical fallback when git unavailable. Cycle detection raises ValueError.

Four test files, 62 fixture-backed tests (no live vault): scripts/test_plan_graph.py, test_standup.py, test_readiness.py, test_merge_order.py.

Fixture tree at scripts/fixtures/plan_graph/_harness/ — three active plans + one queued, covering all frontmatter forms and plan states.

Why this shape

V5-12 built the substrate (the persona primitive + gate); V5-11 is the first persona that actually composes. The team-coordinator is stateless — it owns no engine of its own, just four read-only scripts that map the _harness/ state and answer three coordinator questions: who is building what (standup), what is safe to start next (readiness), and in what order to merge (merge-order). Hard-requiring queue_status_lite ties it to the existing agentm-native read-model; soft-enhancing developer-workflows and github-projects means it degrades cleanly on a bare install with no errors.

The touches: field — YAML frontmatter on plan files — is new optional metadata introduced by this commit. It is a glob list of file patterns the plan modifies, used by readiness.py to detect file-overlap conflicts between concurrently running plans. Plans without touches: are loudly flagged in degrade_warnings rather than silently assumed safe — the loud-degrade contract is the key safety property.

2026-06-16 — v5.2.0: capability-discovery resolver + persona tier

Commit range: v5.1.0..v5.2.0 (6 commits on main). Release notes: v5.2.0. Solo harness MINOR — no crickets pairing.

What shipped

Two roadmap arcs landed together:

V5-8 — the enhances: runtime (ADR 0015). The capability-discovery resolver is the runtime half of crickets' enhances: soft-composition — it answers "is this capability available on this host?" without importing plugin code.

  • scripts/capability_resolver.py — plugin-capability registry + resolver. Aggregates installed plugins' declared capabilities: keys from two host state directories (Claude Code's installed_plugins.json / marketplace manifests; Antigravity's import_manifest.json / per-plugin capabilities.json sidecars). Public API: capability_available(name, *, version=None) → bool and capability_resolve(name) → {available, provider, version, reason}. Claude Code wins the merge when both hosts declare the same capability. 32 unit tests; all four reason codes (available / no-provider / provider-not-installed / version-mismatch).
  • scripts/capability_version_match.py — stdlib-only single-range semver checker. satisfies(installed_version, range_str) → bool. Supports >=, >, <=, <, ==, !=, ~= (PEP 440 compatible-release). Gracefully returns False — never raises — for None versions, malformed strings, or compound specifiers (LC-3: single-check, not a solver). 40 unit tests.
  • scripts/agentm-capability CLI shim (Task 3) — wires the resolver for shell callers; exit 0 (available) / 1 (unavailable) / 2 (usage error).
  • CI gate: check-capability-resolver-one-way — enforces the one-way read contract (resolver never imports plugin code).

V5-12 — the persona tier (ADR 0016). A third classification above the substrate/plugin binary: personas are curated kind: persona markdown manifests that describe a sustained mode of engagement with the agent. They live in personas/ in the repo root, have requires: substrate-native deps, and may optionally list enhances: capabilities for soft-composition.

  • personas/rememberer.md — the first persona manifest; demonstrates the schema and requires: / enhances: fields.
  • scripts/check-personas.py — the check-personas CI gate; asserts requires ⊆ substrate-native (no hard-dep on crickets capabilities) and no always_load: true (personas are opt-in, never injected automatically).
  • scripts/test_check_personas.py — unit tests for the gate.
  • CI wired on Linux, macOS, and Windows.

Why this shape

The two arcs are complementary: V5-8 delivers the runtime that enhances: promises require; V5-12 is the first consumer of the persona-primitive the roadmap reserved. Both are stdlib-only, both are gate-enforced, and both ship without crickets pairing because the contracts they fulfill are harness-substrate concerns — the crickets enhances: orchestration consumes V5-8 at the toolkit surface.

2026-06-13 — v5.0.1: V5-1 follow-on — non-UTF-8 config readers honor their contract (PATCH)

Commit range: v5.0.0..v5.0.1 (2 commits on main: the fix 50cde80 + this release commit). Release notes: v5.0.1. Solo harness PATCH — no crickets pairing.

What shipped

A correctness follow-on to the V5-1 storage seam (shipped in v5.0.0). The four config readers each document a contract: the selection resolver backend_selection.py::_configured_backend is fail-loud (raise StorageSelectionError when the config is present but unparseable), and the three best-effort readers (harness_memory.py::_read_config_vault_path, harness_memory.py::_read_config_state_mode, agentm_config.py::_read_config) are graceful-skip (return None). But each guarded only (json.JSONDecodeError, OSError). A non-UTF-8 config file makes Path.read_text(encoding="utf-8") raise UnicodeDecodeError — a ValueError, which is neither an OSError nor a json.JSONDecodeError — so it leaked past every guard and crashed the caller instead of honoring the documented contract. All four readers now also catch UnicodeDecodeError; five regression tests pin the behavior (the fail-loud resolver raises, the three graceful readers return None, and the doctor storage preview reports [FAIL] rather than crashing).

Why this shape

The realistic trigger is mundane: a Windows editor's UTF-16/BOM "Save As" (\xff\xfe…) on an otherwise-valid config. The fix is the minimal contract-honoring widening — catch the decode error at the same site and route it to the behavior the docstring already promises — not a broad except Exception. The fail-loud path stays loud (a corrupt config still refuses startup with StorageSelectionError, never a silent demotion to device-local, per ADR 0013); the graceful paths stay graceful. Surfaced by an adversarial review of the V5-1 part-5 selection code immediately after the v5.0.0 tag.

2026-06-13 — v5.0.0: Agent M V5 — the memory↔storage seam + the dev-loop unbundling (MAJOR)

Commit range: v4.15.0..v5.0.0 (76 commits on main). Release notes: v5.0.0. This is the first MAJOR since v4.0.0 — two BREAKING refactor(harness)!: commits drove the bump.

Note

Each roadmap arc below had its own per-/work documenter passes during the wave, flipping its pages pending → implemented and filling ## Implementation sections as it shipped. This entry is the release-level reconciliation — the cross-arc summary, the new storage-seam ADR, and the sidebar nav — not a re-document of every commit.

What shipped

Five roadmap arcs converged into one MAJOR release. They group into the V5 substrate (V5-0, V5-1, V5-4, V5-10) and the unbundling-and-convergence breaking changes.

V5-1 — the memory↔storage seam (the headline; a five-part arc). The memory engine now reads and writes its markdown state through a small interface of verbs (resolve / read / write / list / exists / info / mkdir) that hand back an opaque Locator — never a pathlib.Path — so the engine carries no filesystem assumption and a backend can be swapped behind it. The no-Path-leak rule is enforced by an AST-based gate (check-storage-seam-no-path-leak). A named-backend registry resolves a backend by protocol name and reports a miss as absence (get → None), not an error. Two concrete backends register into it: a device-local plain-markdown backend (~/.agentm/memory/, the new zero-setup default) and the vault wrap (today's GDrive-synced Obsidian vault re-presented through the verbs, composing the V5-0 write stack, proven byte-conservative by a never-orphan invariant). A backend-agnostic conformance suite holds every backend to one objective contract on the cross-OS test step. Part 5 shipped selection + fail-loud: a storage.backend config key + a resolver (scripts/backend_selection.py) that picks device-local on a fresh install, vault when a vault_path exists, and a named plugin when configured — refusing loudly with StorageSelectionError (and never demoting to device-local) when the named backend's plugin is uninstalled, the vault is selected with no vault_path, or the config is corrupt. A doctor storage preview shares the resolver's code path so the pre-flight check can never drift from the runtime guard. The seam does not yet route the live engine — the engine cutover is a step beyond V5-1, and the derived index lands in V6.

V5-0 — the vault-write protocol (the concurrency floor underneath the vault backend). A per-vault advisory vault_mutex on a local non-synced path, a content-hash CAS (replacing the Drive-mangled mtime CAS), one canonical fsync'd atomic_write, and a conflict-janitor broadened to four Drive marker families plus the DriveFS lost_and_found/ dump. The protocol is a focused scripts/vault_lock.py, vendored byte-identically into the /memory skill and guarded by a parity gate.

V5-4 — the memory↔process seam (the other seam, facing up). A read-only client (scripts/process_seam.py) through which a process talks to the engine, plus a one-way check-process-seam-import-direction gate enforcing that the edge points one way only.

V5-10 — named plans (the multi-plan substrate slice). A named-plan resolver + session→plan binding (resolve_active_plan, loud-error on a dangling marker), a queue_status_lite read-only multi-plan dashboard, named-plan-aware session-start hooks + doctor, a check-multi-plan-naming gate, and a resolve-active-plan CLI bridge so the crickets phase specs can target named plans without reimplementing precedence.

Seven-section convergence + dev-loop slim (the two BREAKING changes). The documentation taxonomy converged to seven sections (amending ADR 0004). And the vendored dev loop left agentm: migrate-to-diataxis, the phase commands, the review sub-agents, and the vendored documenter / diataxis-author copies were retired — all now provided by crickets plugins (developer-workflows, code-review, wiki-maintenance) with graceful-skip when the plugins are absent. This is the unbundling that repositions agentm as "storage-agnostic memory OS + plugin host" rather than "vendored dev loop."

Why this shape

V5's identity, recorded in ADR 0011, is that the memory engine is the thing only agentm provides; the dev loop is a consumer any host with the crickets plugins can supply. Retiring the byte-duplicated dev-loop copies removes a standing parity tax and drift risk. The seam work (V5-1) is what makes the engine storage-agnostic: a fresh install works with zero setup on device-local markdown, and the vault becomes one backing among several reached through an interface. The fail-loud-never-demote selection guard (ADR 0013) is the load-bearing safety call of that arc — a silent demotion to device-local is exactly what would mis-write or orphan an operator's live vault, so a misconfigured backend stops startup loudly rather than degrading quietly. The vault-write protocol (ADR 0012) is the concurrency floor the seam's vault backend composes; the two process/storage seams (V5-1 + V5-4) are the symmetric down-facing and up-facing boundaries of the engine.

Doesn't do

  • Didn't cut the engine over to the seam (at v5.0.0). recall / reflect / save / evolve and the five memory hooks were byte-unchanged; they still accessed state the old way. Selection resolved which backend a config would use and refused a misconfiguration, but the live read/write path did not route through the seam. The engine cutover shipped in V5-3 (v5.5.0): harness_state_dir / read_state_file / write_state_file / phase_recall / resolve_documenter_context now route exclusively to device-local. See v5.5.0 entry above.
  • Doesn't ship the V6 derived index. The three-tier source / shared-abstracts / local-index taxonomy is reserved in the contract (the Tier / TierLayout / DerivedMaintenance types), but no index, no reindex/changed_since implementation, ships here.
  • Doesn't auto-merge vault conflicts. The vault's conflict_strategy = "whole-file" is a name the selection layer reads, not a merger; the janitor surfaces conflict/base pairs to the operator and resolution stays human judgment.
  • Doesn't fully ship named plans. Named-Plans stays pending (correctly): the readers, the resolve_active_plan binder, the naming gate, the named-plan-aware hooks + doctor, and the CLI bridge are all in main, and the crickets behavioral half (the --name <slug> flag across /work·/plan·/review) shipped 2026-06-12 — but the .harness/active-plan marker writer (the worktree-spawn helper) is not in this range, and the page documents that single remaining blocker as the reason it is not yet implemented.

Tracked as

The five V5 roadmap arcs (V5-0 / V5-1 / V5-4 / V5-10 + the seven-section-convergence + dev-loop-slim breaking work). Three ADRs cover the wave: ADR 0011 (unbundling, 2026-06-11), ADR 0012 (vault-write protocol, 2026-06-12), and ADR 0013 (storage-seam fail-loud selection, added in this release sweep, 2026-06-13).

2026-05-22 — v2.4.3: diataxis-author skill (paired with toolkit v0.11.0)

Commit range: v2.4.2..v2.4.3 (2 commits on main: predecessor deprecation d4d4adf + this release commit). Release notes: v2.4.3. Paired with crickets v0.11.0 (8 toolkit commits across plan #13 parts 1-5).

What shipped

crickets's second major skill after memory: diataxis-author — author + maintain a Diátaxis-style wiki for any repo. Five sub-commands:

  1. /diataxis author <slug> — live authoring guidance: mode classification + template selection + filename style; pre-fills wiki/<mode-dir>/<filename>.md skeleton.
  2. /diataxis classify <file> — single-page mode classification (Tier-1 deterministic heuristic + Tier-2 diataxis-evaluator sub-agent for ambiguous cases).
  3. /diataxis check [--strict] — drift detection (wraps check-wiki.py + adds 4 skill-side heuristics: mode-mixed, stale-cross-ref, template-shape-drift, convention-drift).
  4. /diataxis repair — interactive fix-application; preview-first per finding; dispatches documenter sub-agent for mode-mixed splits.
  5. /diataxis migrate — one-shot legacy → Diátaxis migration (subsumes harness's migrate-to-diataxis predecessor; same contract + .diataxis-conventions.md auto-seed + delegation to /diataxis repair for splits).

Plus: diataxis-evaluator read-only sub-agent (zero filesystem write scope); 4 Diátaxis templates; AgentMemory integration with 3-tier convention fallback (per-repo .diataxis-conventions.md > vault _always-load/diataxis-*.md > ADR 0004 defaults).

Substantive sweep happens entirely on toolkit side (8 toolkit commits + 1 harness commit). Harness side is doc-only this release pair: this Completed-Features row + narrative + paired CHANGELOG entry + the deprecation NOTE on harness/skills/migrate-to-diataxis.md (d4d4adf, shipped during plan part 4).

Why this shape

The operator maintains three Diátaxis-shaped wikis (agentm + crickets + dev-setup) plus the just-shipped MemoryVault parent design. Diátaxis discipline was previously supported only by:

  • scripts/check-wiki.py (strict validator; catches post-write)
  • documenter sub-agent (sweep at /release only)
  • migrate-to-diataxis predecessor (one-shot; never fires after migration)

The gap was live authoring guidance + ongoing drift detection + repair. The new skill ships that gap + subsumes the predecessor + repurposes documenter as the skill's mechanical-write worker (same orchestration + sub-agent pattern as /memory adapt-skills + adapt-evaluator from #7b task 4).

This is the 2nd real dogfood of plan #6's /design skill (first was MemoryVault parent design closed 2026-05-20). Parent design lived through /design author → walk-sections → operator approval as final → /design translate (5 parts) → /design sequence (1 active + 4 queued PLAN.md files) → 5 parts executed in sequence → parent design transitions final → launched on this release.

The paired-release-as-documentation pattern continues from v2.4.0 + v2.4.1 + v2.4.2: substantive change lives on one side (toolkit); the other side (harness) ships a paired PATCH for version-cadence readability. v2.4.3 is the documentation-acknowledgement counterpart to v0.11.0; 4th consecutive paired-doc-only pair — the pattern is now firmly established convention.

Doesn't do

  • Doesn't change harness phase specs. Future PATCH could amend /release to call /diataxis check when skill installed (graceful-skip otherwise) — deferred to keep v1 surface narrow.
  • Doesn't remove harness/skills/migrate-to-diataxis.md — predecessor stays through v1 dogfood window. Removal in a follow-up harness PATCH after /diataxis migrate proves out.
  • Doesn't auto-fork into crickets/skills/ from sub-agent. diataxis-evaluator sub-agent has zero filesystem write scope (stricter than adapt-evaluator's scoped-write-to-_skill-watchlist/).
  • Doesn't ship hooks integration (SessionStart surface; UserPromptSubmit auto-dispatch). Deferred to a v2 task per parent design's §8 Hooks Integration.
  • Doesn't ship cross-skill integration with ROADMAP items #19-#23 — sibling work; ships independently.

Tracked as

2 harness commits in this release cycle (deprecation NOTE + this release commit). No new feature entries in features.json — the new skill is wholly a toolkit-internal capability + the harness-side change is doc-only.

2026-05-22 — v2.4.2: MemoryVault Discovery + Mining (paired with toolkit v0.10.0)

Commit range: v2.4.1..v2.4.2 (1 commit on main). Release notes: v2.4.2. Paired with crickets v0.10.0 (8 toolkit commits across plan #7b tasks 1-7).

What shipped

crickets's memory skill gained five new sub-commands that turn the vault from a static curated store into a living surface:

  1. /memory index-skills — auto-indexer walks SKILL.md files across configured skill paths; writes one kind: skill-pointer entry per skill to <vault>/personal-skills/<repo>/<skill-name>.md. Auto-fires from bash crickets/install.sh against toolkit's own skills/ + sibling agentm/.claude/skills/. Idempotent: unchanged entries skip.
  2. /memory reflect corpus — batched paced walk over ~/.claude/projects/*/<session>.jsonl with skip-resume state file at <vault>/_meta/transcript-reflection-state.json. Dry-run by default — first call counts + estimates without writing; operator re-runs with --execute. Single-session resume granularity.
  3. /memory discover-skills — periodic fetcher over operator-editable source whitelist at <vault>/personal-private/skill-discovery-sources.md. Auto-seeds 4 sources in operator's confirmed priority order: Anthropic Cookbook → awesome-claude-code → awesome-mcp-servers → awesome-llm-apps. Per-source dated snapshot + diff cache. Cadence default 7d; --cadence-check self-throttles for idle-hook integration (extended memory-reflect-idle to call it at end of each pass).
  4. /memory adapt-skills — Pass 1 of the adapt-don't-import workflow. Parses candidates from cached diffs; applies 6-rule rubric (R1 new-tool / R2 complements-convention / R3 agent-building-context / R4 names-primitive / R5 experimental-flag -1 / R6 cross-vendor-proprietary -2); thresholds 3+ HIGH / 1-2 MEDIUM / ≤0 LOW. Enriches with GitHub metadata (owner / repo / stars / archived / last_commit / license SPDX / html_url via unauth API) + trustworthiness signals (operator-editable trusted-orgs whitelist + cross-citation count + activity-recent / permissive-license / high-stars / low-stars / archived-warning). Writes enriched candidate JSONs for the adapt-evaluator sub-agent (Pass 2 — read-only with write allowlist physically scoped to _skill-watchlist/ for adapt-don't-import architectural enforcement).
  5. /memory watchlist — review surface. list / review (interactive) / promote <slugs> / dismiss <slugs> / defer <slugs> --until YYYY-MM-DD [--reason]. Promote = annotation-only; dismiss = archive (never rm); defer = snooze. Non-TTY stdin defaults all prompts to skip (never-silent-action contract).

Substantive sweep happens entirely on the toolkit side (8 toolkit commits across plan #7b tasks 1-7: index_skills.py + reflect.py corpus + discover_skills.py + adapt_skills.py + adapt-evaluator agent + watchlist_review.py + docs + ADR 0007 + paired release; plus one Windows CRLF fix commit per [[wake-on-ci-pattern]] scope expansion). Harness side is doc-only: this Completed-Features row + narrative + paired CHANGELOG v2.4.2 entry. No harness phase spec changes, no adapter changes, no new harness ADR.

Why this shape

Plan #7a (MemoryVault Core, closed 2026-05-20) shipped the static curation surface — auto-recall via hooks + reflection sidecar + tri-modal routing + idea ledger + manual seed-pass. #7b's mandate was the living surface:

  • Indexing installed skills so the agent automatically knows what tools the operator has built (no re-mentioning per session)
  • Mining the historical transcript backlog for durable patterns the manual seed pass missed (~140 sessions in operator's ~/.claude/projects/)
  • Scanning curated internet sources for skill-shaped patterns to potentially adopt
  • Gating adoption through a deterministic Python rubric + LLM sub-agent judgment with adapt-don't-import architecturally enforced — agents physically cannot fork into crickets/skills/; only the operator's manual authoring step graduates a pattern to a real skill

The two-pass adapt-don't-import architecture (deterministic Python Pass 1 + LLM sub-agent Pass 2) is the load-bearing design call. Pure rubric is testable + fast but semantically blind; pure LLM is sharp but expensive + non-deterministic. Pass 1 narrows the surface (drops LOW outright; gates enrichment + sub-agent dispatch); Pass 2 makes the final call. Operators can inspect Pass 1's JSON output to verify the rubric is scoring sensibly before paying the LLM cost.

Stdlib-only Python pipelines (no new third-party deps) align with plan #18's local-first design. GitHub API access via unauthenticated urllib.request with graceful-skip on 60/hr rate limit.

The paired-release-as-documentation pattern continues from v2.4.0 + v2.4.1: substantive change lives entirely on toolkit side; harness still ships a paired PATCH for version-cadence readability.

Doesn't do

  • Doesn't auto-fork into crickets/skills/ — architectural rule enforced by the adapt-evaluator sub-agent's tool allowlist (Write scoped to _skill-watchlist/<source-slug>/<pattern-slug>.md only). The operator's manual authoring is the only path to a real skill.
  • Doesn't auto-dispatch the Pass 2 sub-agent — operator invokes manually via the /memory adapt-skills skill body. Pass 1 (JSON enrichment) is automatic; Pass 2 (judgment + watchlist write) is operator-gated for v1. Future task may add idle-hook auto-dispatch with --limit N.
  • Doesn't change harness phase specs (no discovery-mining logic on harness side — wholly a toolkit-side concern via the memory skill).
  • Doesn't change adapter wrappers (canonical-reference inheritance — adapters point at phase specs which are untouched).
  • Doesn't ship a new harness ADR (the discovery + mining decision lives in toolkit-side ADR 0007).
  • Doesn't process HTML sources — discover_skills.py is markdown-only; HTML pages get cached as raw HTML, diff still works but downstream candidate parsing assumes markdown structure.
  • Doesn't ship the /memory search body — that stub remains for a future task to wire recall.py query into the skill UX.
  • Doesn't ship cross-surface AgentMemory protocol — that's ROADMAP item #22 (queued post-#7b).

Tracked as

Single-commit harness release. No new feature entries in features.json (discovery + mining isn't a net-new user-visible feature on harness side — it's a toolkit-internal architectural extension).

2026-05-20 — v2.4.1: Local-only embeddings (paired with toolkit v0.9.2)

Commit range: v2.4.0..v2.4.1 (1 commit on main). Release notes: v2.4.1. Paired with crickets v0.9.2 (8 toolkit commits across plan #18 tasks 1-7).

What shipped

crickets's memory skill collapsed from dual-mode (Voyage/Anthropic API + local sentence-transformers fallback) to local-only sentence-transformers. Default model upgraded all-MiniLM-L6-v2 (384-d, MTEB English 56.3) → BAAI/bge-large-en-v1.5 (1024-d, MTEB English 64.2). EMBEDDING_DIM bumped 384 → 1024. New AGENT_TOOLKIT_EMBEDDING_MODEL env var as escape hatch for low-spec hosts (still local — no API option). All VOYAGE_API_KEY / ANTHROPIC_API_KEY env var reads removed; MEMORY_USE_API_EMBEDDINGS env var no longer consulted. sentence-transformers becomes a hard install dep (was optional fallback) — install.sh + install.ps1 pip-install it by default from new requirements.txt; opt-out via --no-python-deps. vec_index.py gained a rebuild subcommand + dim-mismatch detection for migrating existing 384-d indexes. Substantive sweep happens entirely on the toolkit side (8 toolkit commits across plan #18 tasks 1-7: embed.py refactor + smoke install fixups + vec_index.py rebuild + local-mode integration test + install scripts + ADR amendment + docs rewrite + paired release). Harness side is doc-only: this Completed-Features row + narrative + the paired CHANGELOG v2.4.1 entry. No harness phase spec changes, no adapter changes, no new harness ADR.

Why this shape

The primary operator is a Claude Ultra subscriber without a separate Anthropic / Voyage API key — the API path was unreachable for the toolkit's actual user. Dual-mode added surface area (mode resolution, env-var contract, dim-truncation, two test paths) without value for the personal-dev-env use case. Modern small-to-mid local models (BGE-large family, mxbai, nomic-embed) deliver near-SOTA MTEB results on desktop-class hardware (M-series + 64GB RAM) — the quality gap that motivated dual-mode is no longer load-bearing.

Plan #18 was inserted mid-flight of plan #7a part 5 (seed-pass) because task 6 (validate via sample recalls) needs a worthwhile embedding model for validation signal to be meaningful. This is the first mid-flight plan insertion in the personal-dev-env: the active PLAN.md was archived to .harness/PLAN.paused.20260520-memoryvault-seed-pass.md, the new plan was written as the active PLAN.md, executed, and after this release pair ships the paused plan is restored as active. The mechanism is captured in plan #18's "How to resume" section + the harness v2.4.1 CHANGELOG entry as a documented precedent for future mid-flight insertions.

The paired-release-as-documentation pattern continues from v2.4.0: substantive change lives entirely on one side (toolkit); the other side (harness) still ships a paired MINOR for version-cadence readability. v2.4.1 is the documentation-acknowledgement counterpart to v0.9.2.

Doesn't do

  • Doesn't change harness phase specs (no embedding-related logic on harness side — embedding is wholly a toolkit-side concern via the memory skill).
  • Doesn't change adapter wrappers (canonical-reference inheritance — adapters point at phase specs which are themselves untouched).
  • Doesn't change scripts, validators, or tests on harness side.
  • Doesn't ship a new harness ADR (the embedding-mode decision lives in toolkit-side ADR 0001's 2026-05-20 amendment).
  • Doesn't auto-migrate existing 384-d vec-indexes — operators see a graceful-skip warning on first invocation with the new toolkit + a clear python3 vec_index.py rebuild --vault-path <path> command (toolkit-side handling).
  • Doesn't ship Antigravity 2.0 / Antigravity CLI host support — that's ROADMAP item #17 (queued post-#7a).

Tracked as

Single-commit harness release. No new feature entries in features.json (embedding-mode collapse isn't a net-new user-visible feature on harness side — it's a toolkit-internal architectural narrowing).

2026-05-17 — v2.4.0: Gemini-CLI host removal (paired with toolkit v0.9.0)

Commit range: v2.3.1..v2.4.0 (1 commit on main). Release notes: v2.4.0. Paired with crickets v0.9.0 (5 toolkit commits across plan #15 tasks 1-5).

What shipped

Standalone Gemini CLI dropped from supported hosts across the personal-dev-env. Antigravity (Gemini-in-IDE) stays — different surface than standalone CLI. Substantive customization sweep happens entirely on the toolkit side (5 toolkit commits across plan #15 tasks 1-5: installer dispatch + manifests + validator/tests + wiki/ADRs + MemoryVault design docs). Harness side is doc-only: this Completed-Features row + narrative + the paired CHANGELOG v2.4.0 entry. No harness phase spec changes, no adapter changes, no new harness ADR.

Why this shape

In practice the operator (one person) runs Claude Code + Antigravity. Standalone Gemini CLI was added defensively in v0.1.0 of the toolkit (then agentm v1.0.0 era — the original three-adapter scope) but never grew into the workflow; the Gemini usage that does happen lives inside Antigravity's IDE-level integration. Maintaining a third host destination, dispatch arms in install.{sh,ps1}, a third column in Per-Host-Paths.md, three case-arms in every dispatch function, and three branches in tests was carrying maintenance cost without observed payoff. Plan #7a part 1 (memory skill scaffold, shipped 2026-05-16) was the first new skill that opted out of the three-host scope from day 1; plan #15 (executed 2026-05-16/17) sweeps the rest of the toolkit to match.

The split between toolkit (substantive customization sweep) and harness (doc-only paired release) follows the customization-vs-phase pattern from agentm ADR 0006: customizations live in toolkit; phase-gated workflow lives in harness; the two integrate via shared template + shared workflow contract. The host-scope decision is entirely a toolkit-side concern; harness inherits via its dependency on toolkit customizations.

The paired-release-as-documentation pattern (new in v2.4.0): when the substantive change lives entirely on one side of the toolkit/harness split, the other side still ships a paired release with framing-only content. This keeps the two repos' version cadences readable for operators tracking changes — they don't have to wonder "why did toolkit ship a MINOR but harness didn't?". v2.4.0 is the documentation-acknowledgement counterpart to v0.9.0.

Doesn't do

  • Doesn't change harness phase specs (no host-related conditionals to update — phases don't reference specific hosts by name).
  • Doesn't change adapter wrappers (canonical-reference inheritance — adapters point at phase specs which are themselves untouched).
  • Doesn't change scripts, validators, or tests on harness side (no harness-side customizations to validate since the v2.0.0 split).
  • Doesn't ship a new harness ADR (the host-scope decision lives in toolkit-side ADR 0006).
  • Doesn't auto-clean up legacy .agents/skills/ on harness installs — that's toolkit-side install.sh behavior, gated by --no-legacy-cleanup flag.

Tracked as

Single-commit harness release. No new feature entries in features.json (host-scope reduction isn't a net-new user-visible feature — it's a removal). The legacy-cleanup-prompt operator UX is documented in toolkit-side Installer-CLI reference + ADR 0006 + CHANGELOG v0.9.0.

2026-05-16 — v2.3.1: /plan external-review-handoff option (paired with toolkit v0.8.1)

Commit range: v2.3.0..v2.3.1 (1 commit on main). Release notes: v2.3.1. Paired with crickets v0.8.1.

What shipped

Adds the external-review-handoff option to the harness's /plan phase. After the agent drafts .harness/PLAN.md (per the existing flow), the operator now has an alternative to inline iteration: hand off the drafted PLAN.md to Antigravity IDE for inline-comment review + Gemini-applies-comments revision, then resume in Claude Code with a diff-on-resume pass against a pre-handoff snapshot.

The harness writes a pre-handoff snapshot at .harness/PLAN.pre-handoff-<ts>.md, generates a transfer-context file at .harness/transfer/plan-<ts>.md (using the design skill's template at harness/skills/design/templates/transfer-context.md post-v4.0.0 — pre-v4.0.0 the template lived at crickets/skills/design/templates/transfer-context.md per the V4 #36 reorg; DOC_TYPE: plan triggers harness-PLAN.md-specific guardrails), outputs a handoff prompt with explicit Antigravity steps, and pauses the phase. On resume (/plan --resume-external-review or natural "plan review complete"), the harness diffs the revised PLAN.md against the snapshot, reads Gemini's change-summary log at .harness/PLAN.diff.md, surfaces findings, asks Accept / Iterate / Discard.

Why this shape

Dogfood-driven amendment from plan #6's first real design exercise (MemoryVault, 2026-05-15). The 6-chunk inline walk of a ~7200-word design surfaced a real UX gap: Claude Code's block-by-block review pattern works but tires fast on long content. Antigravity IDE has a native inline-comment UI + Gemini AI integration that handles bulk-apply of comments dramatically better.

The harness /plan phase faces the same pattern when drafting plans for substantial scope (the MemoryVault-style plans with many tasks + thick locked-design-calls sections). Mirroring the option from toolkit /design skill v0.8.1 means operators have the same workflow available in both surfaces with the same mechanics — shared transfer-context template, shared workflow shape, shared cleanup discipline. One mental model, two skill surfaces.

The split between toolkit (template + design-skill option) and harness (/plan option) follows the customization-vs-phase pattern from agentm ADR 0006: customizations live in toolkit; phase-gated workflow lives in harness; the two integrate via shared template + shared workflow contract.

Doesn't do

  • Doesn't change adapter wrappers (canonical-reference inheritance — adapters point at phase specs).
  • Doesn't require any script changes, manifest changes, or installer changes. Implementation lives entirely in phase spec documentation; the agent executes the documented flow.
  • Doesn't change the inline-review path. The inline iteration path stays default; external-review is opt-in per session.
  • Doesn't ship cleanup automation for .harness/transfer/ — that's manual until MemoryVault's idle-time hook (plan #7a) lands, at which point the same 30-day GC pass handles transfer artifacts alongside crash-recovery markers.

Tracked as

This patch ships a single new option in the /plan phase; not flagged in features.json (features.json tracks net-new user-visible features; this is an alternative path for an existing feature).

2026-05-15 — v2.3.0: /release + /setup integration for crickets's /design skill

Commit range: v2.2.0..v2.3.0 (2 commits on main). Release notes: v2.3.0. Paired with crickets v0.8.0.

What shipped:

  • /release §1b "Design-doc lifecycle check (crickets)" — new section between §1 (Verify plan completion) and §2 (Re-run gates). Three cases: (A) silent no-op when plan isn't design-sourced; (B) archive completed plan + promote next queued plan + halt /release when more parts remain in the design; (C) archive + transition parent design Status final → launched + update wiki/Home.md + _Sidebar.md to surface launched published designs + continue release flow when this was the LAST queued part. Graceful-skip silent no-op when no design-doc origin signal present.
  • /setup §7 (Populate the wiki scaffold) extended with wiki/explanation/designs/ landing dir bullet — cross-refs the crickets /design skill how-to + the §1b /release lifecycle.
  • templates/wiki/explanation/designs/ — NEW scaffold dir installed by install.sh's per-file walk. Contents: .gitkeep + README.md (one-paragraph explanation of visibility routing rules, Status lifecycle, wiki surfacing trigger, toolkit dependency).
  • scripts/check-references.py — EXTERNAL_CUSTOMIZATIONS extended with design entry (currently forward-compatibility documentation because phase specs use slash-command phrasing `/design` which doesn't match INVOKE_SKILL_RE — inline comment captures this honestly).
  • /work Step 11 summary template enhancement for ROADMAP-driven multi-plan projects — opt-in via the .harness/ROADMAP.md signal. Adds roadmap context lead-in + ✅/⬜ chart + link block to .harness/ state files + explicit handoff phrase. Universal applicability — any harness install with a roadmap benefits.

Why it shipped this shape:

The harness needed integration hooks for the crickets /design skill's per-part PLAN.md workflow. The toolkit-side skill writes PLAN.md files to .harness/ (active + queued); without the harness lifecycle hook, operators would have to manually promote queued plans after each part's Status: done completion. v2.3.0's §1b automates that promotion + handles the design final → launched transition + wiki surfacing for published designs.

The split between toolkit (skill body) and harness (lifecycle integration) follows the customization-vs-phase pattern from agentm ADR 0006: customizations live in toolkit; phase-gated workflow lives in harness; the two integrate via well-defined hand-off points. v2.3.0 ships the harness-side hand-off; v0.8.0 of the toolkit ships the skill that writes to it.

The /work Step 11 enhancement came out of the dev-flow codification work (separate from plan #6 but shipping in the same release window). It's the universal good — opt-in via .harness/ROADMAP.md signal so single-plan installs stay minimal; multi-plan projects get the navigation aids that match their scale.

What it doesn't do:

  • Doesn't ship the /design skill itself. That lives in crickets v0.8.0.
  • Doesn't auto-detect orphan queued plans without parent_design_doc: frontmatter. The §1b detection signal is the frontmatter field; hand-authored plans without it skip §1b entirely.
  • Doesn't surface confidential designs in the wiki. The visibility check is hard — confidential designs at .harness/designs/ never appear in wiki/Home.md even at launched Status.
  • Doesn't add a new harness ADR. The design decision lives in crickets ADR 0004 since the customization itself lives there.

Tracked as:

  • Task 5 of plan #6 (design skill v1) in .harness/PLAN.md. Plan #6 is a 7-task project spanning both repos: tasks 1-4 + 6 in crickets (template + 3 sub-command bodies + docs); task 5 in harness (this release); task 7 is the coordinated release pair.

2026-05-14 — v2.2.0: /work + /release augmentable with crickets's base hooks

Commit range: v2.1.0..v2.2.0 (1 commit on main). Release notes: v2.2.0. Paired with crickets v0.7.0.

What shipped:

  • New section in /work phase spec (harness/phases/03-work.md): "Long-running /work — operator-control hooks (crickets)". 20-line section between "When to invoke /review" and "Failure modes to avoid". Reference table for all three hooks (kill-switch / steer / commit-on-stop); when-they-earn-their-keep framing (runaway loop / mid-task redirect / crashed session); alphabetical-ordering invariant (kill-switch fires before steer in PreToolUse); graceful-skip framing.
  • New section in /release phase spec (harness/phases/05-release.md): "Optional: commit-on-stop safety net (crickets)". Shorter 4-line section focused on commit-on-stop as the backstop for interrupted release flows (mid-CHANGELOG-edit, mid-tag-prep); cross-refs the /work section for the full hook lineup.
  • scripts/check-references.py EXTERNAL_CUSTOMIZATIONS extended with kill-switch, steer, commit-on-stop. Inline-commented as forward-compatibility documentation — the existing regexes don't currently match hook phrasings.
  • No adapter edits. All six /work + /release wrappers (3 hosts × 2 phases) reference the canonical specs at harness/phases/0{3,5}-*.md exactly once; the new sections inherit via the existing canonical-reference pattern.

Why it shipped this shape:

The three base hooks lifted from cwc-long-running-agents give the operator precision that didn't exist before:

  • Runaway loop: today, the only way to halt is closing the session. touch .harness/STOP is precise — the next PreToolUse blocks the tool call without ending the session.
  • Mid-run redirect: today, the only way to redirect is interrupt-and-restart. Writing .harness/STEER.md injects the redirect into the next tool call's context; file is renamed to .harness/STEER.consumed-<ts>.md for audit trail.
  • Crash recovery: today, a crashed session loses uncommitted work. commit-on-stop fires on Claude Code's Stop event (turn-end) and saves dirty trees to auto-save/<ts> branches automatically. Recovery via git checkout.

/work is the primary consumer because long-running iteration loops, mid-task redirects, and crashed sessions all happen there. /release benefits less (the release flow is typically short) but the commit-on-stop backstop reduces the cost of an interrupted CHANGELOG edit or tag prep.

Splitting the hooks into crickets (not bolting them onto the harness) keeps the harness phase-shaped: the harness owns the phase workflow + canonical sub-agents + setup-specific skills; crickets owns customizations that ride on top. Anyone (harness user or not) can install the toolkit on top to get the precision layer. Graceful-skip framing on both new sections means a harness without the toolkit installed still satisfies the phase contracts.

What it doesn't do:

  • Doesn't auto-dispatch the hooks from any phase. The toolkit's installer registers them in Claude Code's settings.json; once installed, they fire on every relevant event. Phase specs document the convention; the firing is host-level, not phase-level.
  • Doesn't add a new harness ADR. The design decisions (per-repo file location, audit-trail rename, safety-branch not current-branch, Stop-event-only for v0.7.0, alphabetical ordering, claude-code-only scope, Python helper for settings merge) live in crickets ADR 0003 since the customizations live there.
  • Doesn't require the toolkit. Without crickets installed, both new sections graceful-skip silently and the existing flows continue to satisfy the phase contracts.
  • Doesn't ship hooks for Antigravity or Gemini CLI. Both lack first-class hook surfaces today. Manual equivalents (always-on rules / operator prompts that check the trigger files between steps) are documented in crickets's how-to but no scripts ship for them.

Tracked as:

  • Task 3 of plan #4 (base operator-control hooks) in .harness/PLAN.md. Plan #4 is a 5-task project spanning both repos: tasks 1, 2, 4 in crickets (installer + bodies + docs); task 3 in harness (this release); task 5 is the paired release.

2026-05-13 — v2.1.0: /review augmentable with crickets's evaluator

Commit range: v2.0.0..v2.1.0 (1 commit on main). Release notes: v2.1.0. Paired with crickets v0.6.0.

What shipped:

  • New §3b in /review phase spec (harness/phases/04-review.md) — "Optional: evaluator augmentation (crickets)". Documents how to dispatch the evaluator sub-agent alongside the existing adversarial-reviewer flow. Covers when to add evaluator dispatch (PLAN.md Verification clause is a numbered list of falsifiable claims), when to skip (vague rubric or toolkit not installed — graceful-skip), the ARTIFACT: + RUBRIC: dispatch prompt shape, the PASS / NEEDS_WORK output shape with per-rubric-item PASS/FAIL + final Verdict, treat-as-finding semantics (NEEDS_WORK counts as the executable exit artifact the phase requires), and a comparison table laying out the complementary framings.
  • Cross-repo agent references resolve (scripts/check-references.py). Renamed EXTERNAL_SKILLS → EXTERNAL_CUSTOMIZATIONS; added evaluator to the set; the exclusion now applies to both DISPATCH_AGENT_RE and INVOKE_SKILL_RE regexes. Inline comments name each entry's crickets home (skills/dependabot-fixer/, skills/ship-release/, agents/evaluator.md).
  • No adapter edits. All three review adapter wrappers (claude-code/commands, antigravity/workflows, gemini/commands) already reference harness/phases/04-review.md exactly once, so §3b inherits via the existing canonical-reference pattern without per-adapter changes.

Why it shipped this shape:

The adversarial-reviewer has framed /review since v0.8.0: "the code under review likely contains bugs, find them." That framing works well for defect surfacing but doesn't give a binary verdict against an explicit rubric. When the PLAN.md task's Verification clause is precise — a numbered list of falsifiable claims, which is the typical shape — the natural verification is "did the diff satisfy claims 1–5?" not "are there bugs?" The evaluator adds that binary-judgment surface without disturbing the existing flow: it coexists, not replaces. Consumers needing precise grading dispatch the evaluator; consumers needing defect surfacing dispatch the adversarial-reviewer; both useful at the same time.

Splitting the evaluator into crickets (rather than adding harness/agents/evaluator.md) keeps the harness phase-shaped: the harness owns the phase workflow + canonical sub-agents needed by every adapter; crickets owns customizations that ride on top. Anyone (harness user or not) can dispatch the evaluator from any consumer context. The future design skill (#6), quality-gates bundle (#10), and ContextVault (#7) all consume the evaluator for per-step grading.

What it doesn't do:

  • Doesn't replace adversarial-reviewer. Both shipped; /review documents the choice.
  • Doesn't auto-dispatch the evaluator from /review. Explicit dispatch stays the caller's call; the §3b section is a documented option, not a default flow change.
  • Doesn't require the toolkit. Without crickets installed, §3b graceful-skips silently and the adversarial-reviewer-only flow continues to satisfy the phase contract.
  • Doesn't add a new harness ADR. The design decision (read-only allowlist, caller-supplied inline rubric, coexist not replace, structured output) lives in crickets ADR 0002 since the customization itself lives there.

Tracked as:

  • Task 3 of plan #3 (fresh-context evaluator) in .harness/PLAN.md. Plan #3 is a 5-task project spanning both repos: tasks 1, 2, 4 land in crickets (installer + body + docs); task 3 is the harness-side wiring (this release); task 5 is the coordinated release pair (this release + crickets v0.6.0).

2026-05-12 — v2.0.0: crickets repo split; dependabot-fixer + ship-release migrated

Commit range: v1.0.0..v2.0.0 (9 commits on main). Release notes: v2.0.0. ADR: 0006 — crickets split. Paired with crickets v0.5.0.

What shipped:

  • Sibling repo split. The new crickets repo holds personal agent customizations (skills, sub-agents, hooks, MCP servers, slash commands, bundles, etc. — 11 primitive types) that ride on top of the harness's phase-gated workflow. dependabot-fixer and ship-release migrated from this repo to the toolkit (both were host-cross-cutting with no harness shape). doctor and migrate-to-diataxis stay in this repo — doctor is harness-setup-specific and migrate-to-diataxis is harness-shaped (encodes ADR 0004).
  • Shared lib/install/ byte-identical across repos. Extracted ~80 lines of inline install primitives from install.sh + install.ps1 into a new shared lib with 6 bash + 8 pwsh functions plus a CONTRACT.md documenting the caller contract (UPDATE_MODE/$Update flag + BOUNDARY_ROOTS/$BoundaryRoots array + six behavior invariants). SHA-256 manifest committed in both repos. Cross-repo updates flow through scripts/sync-lib.sh (canonical → sibling); scripts/check-lib-parity.sh asserts self-consistency in CI on every push. Cross-platform byte-identity work surfaced four real Mac + Windows bugs (locale-dependent sort collation, $host collision in PowerShell, missing shasum in Git Bash, autocrlf + binary-mode SHA-256 differences) — all fixed before v2.0.0 tag.
  • PII + lib-parity CI gates in this repo. New pii-guardrails job in all three per-OS workflows runs scripts/check-no-pii.sh (regex scanner, byte-copied from the toolkit) and the official gitleaks/gitleaks-action@v2. New lib-parity job runs scripts/check-lib-parity.sh. Both repos now share the same PII detection surface, with the toolkit's pre-push hook layer + agent-facing pii-scrubber skill providing the additional remediation layers on that side.
  • Graceful-skip framing for migrated skills. harness/phases/05-release.md's ship-release suggestion and harness/phases/03-work.md's feature-flip suggestion both note "install crickets to enable; otherwise cut release manually with gh release create". harness/skills/doctor.md probes 3 + 5 skip cleanly if the skills aren't installed. The harness still works on its own for the full phase-gated workflow; only the two migrated skills require the sibling install.

Why it shipped this shape:

The triggering observation, captured in ADR 0006, was that the parity tax scales linearly with personal customizations: every skill we'd want to add (kill-switch, fresh-context evaluator, ContextVault, a design skill, pii-scrubber) would need a canonical spec under harness/skills/ + adapter copies under each of three adapter trees + parity script updates + reference checks. Past two or three skills, the tax becomes the dominant work. The harness also has a clear identity (phase-gated workflow + on-disk state + adversarial review primitive + Diátaxis convention) — mixing personal-customization scope into that identity blurs both. Splitting the repo lets the harness stay tight (six phases + canonical sub-agents + setup-specific skills) while the toolkit takes the open-ended customization scope with its own conventions (manifest schema + per-host paths dispatch + 11-primitive scope).

The byte-identical lib/install/ is the load-bearing piece. Both repos need essentially the same install plumbing (boundary guard + per-file copy modes + true-sync wipe-and-recreate for --update); copying the code with drift would create silent divergence the moment one repo fixes a Windows bug the other doesn't. Byte-identity + CI gate makes drift impossible.

The cross-platform debugging work was a nice forcing function. Three of the four bugs surfaced in the Mac + Windows CI workflows on the toolkit side before any user hit them — exactly the kind of friction the three-OS matrix is meant to catch early. Each fix landed in both repos with parallel commits cross-referencing the sibling's SHA.

What it doesn't do:

  • Doesn't ship a CLI sugar layer to invoke both tools as harness and crickets on PATH. That requires dev-machine-setup changes and lands in a future plan.
  • Doesn't pre-install the toolkit alongside the harness. Users opt in by cloning crickets as a sibling directory and running its installer separately. Graceful-skip framing keeps the harness functional without it.
  • Doesn't migrate doctor or migrate-to-diataxis. Both are harness-shaped; moving them would be a category error.
  • Doesn't redesign migrate-to-diataxis into a general-purpose Diátaxis authoring skill. That's tracked as a separate roadmap item.

2026-05-11 — v1.0.0: Three-adapter scope; Codex dropped; 1.0.0 commitment

Commit range: v0.9.0..v1.0.0 (13 commits on main). Release notes: v1.0.0. ADR: 0005 — Drop Codex support.

What shipped:

  • Codex adapter removed. Supported hosts narrow from four to three: Claude Code, Antigravity, Gemini CLI. adapters/codex/ (15 files), harness/agents/codex-adapter-research.md (294 lines), and codex-specific code across five scripts all gone. Repo-public surfaces (README, AGENTS.md, adapter READMEs, 9 wiki pages) scrubbed of Codex mentions. Historical entries in CHANGELOG.md and past-release sections of this page deliberately preserved as history.
  • True-sync --update semantics. Beyond removing the codex install code, install.sh and install.ps1 now wipe twelve fully-harness-authored subdirs before recreating from source on --update. Orphan paths from prior versions (e.g. .codex/ from v0.9.0 installs) are automatically removed and reported as removed legacy <path>/. User state files at .harness/ root, merged settings.json files, wiki/**, and root AGENTS.md/CLAUDE.md are deliberately preserved. The mechanism generalizes: any future host or skill removal also auto-cleans without per-removal patches.
  • v1.0.0 commitment. Semver becomes firm going forward: major = breaking, minor = additive, patch = fixes. The harness's pre-1.0 churn period closes; future breaking changes (e.g. dropping Antigravity, restructuring adapters) become explicit major-version events, and the planned roadmap (crickets repo split, ContextVault, design skill, base-skill primitives, evidence-tracking) becomes clear minor bumps.

Why it shipped this shape:

The Codex adapter had been paying real ongoing costs without offsetting workflow value: Codex's built-in /plan and /review collisions forced a harness- prefix on every Codex phase-command (the only adapter with that divergence); the codex install block was a side-channel for delivering Gemini's shared skills (.agents/skills/), which made the codex removal load-bearing for two hosts; and the personal-dev-env scope had narrowed to Claude Code + Antigravity + Gemini CLI. Combined with the harness's maturity, this was the right moment to graduate to v1.0.0 — the host-scope reduction is a breaking change anyway, and a firm-semver 1.0 floor better communicates the stability commitment than another 0.x point release.

The --update true-sync amendment is worth noting separately. The user surfaced it during task 2 closeout: "removing the codex install code stops new installs from creating codex paths, but --update on an existing v0.9.0 install leaves orphan files." Rather than ship a codex-specific cleanup patch, the fix was generalized: declare MANAGED_PARENTS (12 subdirs that are fully harness-authored), wipe them on --update, then run the normal install flow which recreates from source. Codex becomes the first user of a mechanism that handles all future removals.

What it doesn't do:

  • Anyone running agentm through Codex has no harness adapter post-v1.0.0. The phase-gated workflow is host-agnostic, but they must migrate to one of the three remaining adapters.
  • Codex's built-in /plan and /review semantics will not be harness-aware in a Codex session against a harness-installed project.
  • cross-review.sh previously listed codex as an option for true cross-vendor review; that fallback drops to claude only.

Tracked as:

  • 5-task plan in .harness/PLAN.md (Codex-removal sweep) — all tasks [x], plus a task-2 amendment for the true-sync --update semantics.
  • v1.0.0 — release notes, CHANGELOG.md

2026-04-23 — v0.9.0: Diátaxis documentation spec + /doctor skill

Commit range: v0.8.7..v0.9.0 (10 commits on main). Release notes: v0.9.0.

What shipped:

  • Diátaxis four-mode wiki convention end-to-end. ADR 0004 supersedes ADR 0002's audience-based layout (wiki/{development,operational,design,architecture}/) with the four Diátaxis modes — tutorials/, how-to/, reference/, explanation/ (with explanation/decisions/ for ADRs). The rollout landed as a 7-task plan: (1) scripts/check-wiki.py shipped as a structural lint with 11 rules (a–k); (2) templates/wiki/ reshaped so new installs land directly in the four-mode layout; (3) this repo's own wiki/ migrated file-by-file with git mv to preserve blame; (4) the documenter sub-agent rewired to write to mode-specific targets per phase; (5) a new migrate-to-diataxis skill for one-shot conversion of already-installed projects; (6) check-wiki.py flipped from warn-only to --strict in CI; (7) harness phase specs retargeted to the new mode dirs.
  • /doctor skill — companion to telemetry.sh for post-install correctness. Default mode runs structural discovery only: verifies expected phase commands, sub-agents, skills, state files, and hooks are present and parseable in the detected adapter (<5s, no tokens). --live adds six real probes — explorer dispatch on a trivial prompt, adversarial-reviewer dispatch requiring an executable artifact (not prose), ship-release --dry-run, migrate-to-diataxis preview on an already-migrated tree, dependabot-fixer no-match path, and a hook synthetic trigger. Never mutates repo state. Canonical spec at harness/skills/doctor.md; adapter wrappers for claude-code, antigravity, and codex (Gemini reuses the Codex delivery).
  • CONTRIBUTING.md extracted from the README (which dropped 126 → 64 lines). CI matrix, invariant list, and local-gate command set now live at their natural home.

Why it shipped this shape:

Diátaxis gives readers a clear mental model before they open a page — "learn / do / look up / understand" is more durable than "dev / ops / design / architecture" (which conflates audience with intent, and blurs when a page serves multiple audiences). The migration skill exists because ADR changes that break installed projects are a tax the harness should pay, not the user. /doctor exists because file-presence smoke tests answer "is it there" but not "does it work", and several install regressions over the past quarter could have been caught pre-use by a cheap structural + live-probe check.

First dogfood of /doctor caught a real spec bug: the initial skill required a name: frontmatter field on every surface, but Claude Code phase commands, Antigravity workflows, and Gemini TOML commands intentionally have no name: field (name is implicit from filename). Spec and all three adapter wrappers were corrected inside the same release (d078485). Live probes (explorer and adversarial-reviewer) both matched their pass criteria — adversarial returned a file:line pointer plus a failing pytest body in 10.8s rather than prose.

What it doesn't do:

  • No auto-install on top of a half-installed tree — /doctor reports gaps and points at install.sh; auto-repair would mask misconfiguration.
  • No CI coverage for /doctor itself — the skill dispatches sub-agents, which requires an LLM session and can't run in headless CI. scripts/check-parity.sh and check-references.py catch the structural facets that don't need an agent.
  • No additional Diátaxis modes. Five-mode extensions (glossary, changelog) were explicitly rejected in harness/documentation.md §Non-goals — glossaries live under reference/, changelogs under reference/Completed-Features.md.

2026-04-21 — v0.8.7: GitHub Projects wiring + documenter end-to-end dogfood

Commit range: 801dbd7^..HEAD (4 commits, all on main).

What shipped:

  • GitHub Projects surface across all four phases. /plan, /work, /review, and /release each now offer to file deferred-work items to a user- or org-owned Project linked to the repo, preview-and-ask at every gh call, graceful-skip when .harness/project.json is absent. Propagated to all four adapters (claude-code, antigravity, codex, gemini). See GitHub-Projects-Integration.
  • ProjectsV2 ownership-and-linking decision. The dogfood run surfaced that ProjectsV2 has no repo-owned form; /setup now runs a two-step gh project create + gh project link --repo flow to make the project visible under the repo. Rationale in ADR 0003.
  • Dropped the "1 proposal per session" cap. Replaced with a quality-bar-plus-batching rule (single preview at phase end, per-phase soft caps as reminders not hard limits). Avoids silent misses when a session genuinely surfaces multiple deferrals.
  • README refresh to v0.8.2. /setup scope; not documenter's edit — main agent's. Removed stale "v0.1" string, added ship-release skill, added documenter sub-agent, added wiki-sync pointer.

Why it shipped this shape:

The /bugfix Issues lifecycle shipped in v0.8.2; this plan closed the symmetric half — the "defer this for later" flow that parallels "fix this now". The heuristic for detecting deferrals is intentionally soft (LLMs will miss or over-propose); mitigation is the mandatory preview-and-ask plus the per-phase batching rule. A noisy proposal the user declines is cheap; a silent miss is recoverable.

What it doesn't do:

  • Task 3 part B ("observe an offer-accept or offer-decline cycle in a real phase session") is still gated. The feat-gh-projects-integration.passes flag stays false until a future phase session exercises the wiring on a real deferral.
  • No auto-detection of org vs user ownership; the user picks interactively at /setup.
  • Classic (pre-ProjectsV2) projects aren't supported.
