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

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

What shipped:

  • New §3b in /review phase spec (harness/phases/04-review.md) — "Optional: evaluator augmentation (agent-toolkit)". 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 agent-toolkit 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 agent-toolkit (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; agent-toolkit 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 agent-toolkit 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 agent-toolkit 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 agent-toolkit (installer + body + docs); task 3 is the harness-side wiring (this release); task 5 is the coordinated release pair (this release + agent-toolkit v0.6.0).
  • v2.1.0 — release notes, CHANGELOG.md
  • Paired release: agent-toolkit v0.6.0.

2026-05-12 — v2.0.0: agent-toolkit 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 — agent-toolkit split. Paired with agent-toolkit v0.5.0.

What shipped:

  • Sibling repo split. The new agent-toolkit 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 agent-toolkit 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 agent-toolkit 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 agent-toolkit 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 (agent-toolkit 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 agentic-harness 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.
