Repo Layout

Repo layout

The top-level layout of agentm on disk. For why this shape, see How the pieces fit, ADR 0001, and ADR 0002.

⚡ Quick Reference

Question	Answer
Where does a phase spec live?	Not in agentm — the phase loop (/setup /plan /work /review /release /bugfix) ships in the crickets developer-workflows plugin since the V5 unbundling (ADR 0011). agentm owns the durable state substrate the phases run on, not the specs.
Where does an adapter live?	adapters/<host>/ — claude-code, antigravity (the two supported hosts).
Where does the install scaffold live?	templates/ — state files, hooks, wiki scaffold.
Where does the test infra live?	scripts/ — never propagated to target projects.
Where does this wiki get copied from on install?	Nowhere. Target projects get templates/wiki/ (an empty scaffold), not this one — see ADR 0002.
Where do personal customizations live?	crickets — the sibling toolkit repo (since v2.0.0 / ADR 0006).
Where does the shared install plumbing live?	lib/install/ — byte-identical to crickets/lib/install/; synced via scripts/sync-lib.sh, parity-gated in CI.
Where does the vault-less mode signal live?	Two on-host layers — the device-level state_mode in <install-prefix>/.agentm-config.json and the higher-precedence per-repo <repo>/.harness/.project-mode. See Single-repo state mode.

The supported adapters

Since the V5 unbundling (ADR 0011) each adapter ships only agentm's own surfaces — the phase-gated dev loop and the review sub-agents moved to the crickets developer-workflows / code-review plugins, so there is nothing to parity-check there (their absence is pinned by scripts/test_devloop_slim_retired.py). scripts/check-parity.sh asserts what remains matches across hosts.

Adapter	Ships (agentm's own surfaces)
adapters/claude-code/	the recent-wiki-changes utility command (.claude/commands/) · the doctor skill (.claude/skills/doctor/)
adapters/antigravity/	the always-on rules — operating contract + vault context (.agents/rules/{harness,agentmemory-context}.md); the workflows/ + skills/ dirs were removed in the slim

A third directory, adapters/gemini/, remains in the tree but is not a supported host — Gemini CLI was dropped in v2.4.0 (Compatibility). Its removal is pending reconciliation.

Canonical sub-agents (harness/agents/): adapt-evaluator, memory-idea-researcher — the memory-engine pair. The review sub-agents (explorer, adversarial-reviewer, adversarial-reviewer-cross) and documenter are crickets-provided (code-review / developer-workflows / wiki-maintenance plugins) since the V5 unbundling (ADR 0011).

Canonical skills (harness/skills/): design, doctor, memory, ship-release, wiki-author. Wiki authoring's diataxis-author is provided by crickets' wiki-maintenance plugin (graceful-skip if crickets is not paired), recommended by name like dependabot-fixer / pii-scrubber.
