Claude Code's (and Copilot's) native plugin installer has zero awareness of .apm/ nesting -- it convention-scans only flat skills/, agents/, commands/, hooks.json at each plugin's root. Confirmed via strings on the installed claude binary and live installs of git@holocron/gitea@holocron/kyberforge@ holocron, all reporting Skills(0) Agents(0) Hooks(0) post ADR-0015's apm conversion. Root cause (apm_cli/core/plugin_manifest.py): apm's plugin.json compiler deliberately strips skills/agents/commands keys, assuming the host already auto-discovers those convention directories -- it has no model of .apm/ being host-visible at all. Separately, apm's own bundle exporter (apm_cli/bundle/plugin_exporter.py, behind `apm pack --format plugin`) implements the correct .apm/ -> flat mapping, but only ever targeted build/<name>-<version>/, a path nothing in marketplace.json's source: points at. scripts/sync-plugin-content.sh wraps that bundle exporter and copies its agents/, skills/, commands/, instructions/, extensions/, and merged hooks.json back into each plugin's own root as a second tracked compiled-output category -- same governance status as .claude-plugin/plugin.json: generated from .apm/, never hand-edited. tests/ subdirectories are excluded from the mirror (dev fixtures, not host-visible runtime content; several hardcode a relative repo-root walk-up sized for the .apm/-nested depth, which breaks when duplicated one level shallower). Applied for real across all 6 plugins and verified two ways: `claude plugin validate --strict` passes on every real plugin directory, and a live `claude --plugin-dir <path> -p "list skills/agents"` behavioral test confirms content is now actually discovered. Also, from the same issue #90 review round: - scripts/check-manifests.sh pointed at each plugin's root-level plugin.json (checking skills/hooks/mcpServers/agents pointer fields) -- that file was a stale near-duplicate of .claude-plugin/plugin.json nothing else read or wrote, now deleted across all 6 plugins. check-manifests.sh is rewritten to validate .claude-plugin/plugin.json instead, and drops the pointer-field checks entirely (nothing to check -- those fields are correctly absent by design). Content-presence drift is now check-plugin-content-sync's job, a new pre-push hook wired in .pre-commit-config.yaml. docs/adr/0017 records the root cause and decision in full, including two rejected alternatives (patching plugin.json's path fields directly -- apm's compiler strips them on every run; pointing marketplace.json at apm pack's build/ output -- a version-suffixed non-source directory nothing can install from without an extra build step). ADR-0015 and CONTEXT.md are updated to point at it. Refs: #90

| agentsmd-author | Use when the user wants to create or update a repo's AGENTS.md file ("write an AGENTS.md for this repo", "add setup/test instructions for agents", "update AGENTS.md", "give this package its own AGENTS.md") — even if they don't name the file explicitly, e.g. "document this for AI coding tools" or "make sure agents know how to run tests here". Writes/updates AGENTS.md by exploring the target repo for real build, test, lint, and style conventions — never invents commands. Supports nested monorepo placement (a subdirectory can get its own AGENTS.md following nearest-file-wins precedence). Closes every run by invoking agentsmd-audit inline, and calls provider-adapter-author when an existing provider file (CLAUDE.md, etc.) now duplicates what AGENTS.md owns. Do not use to review an existing AGENTS.md without changing it — use agentsmd-audit instead. Do not use to convert CLAUDE.md/.cursor/rules into a thin adapter — use provider-adapter-author instead. | Bash Read Write Edit |

Gotchas
- Never invent a command. Every line under a setup/test/build section must come from something you actually found in the repo (
package.jsonscripts, aMakefiletarget, a CI workflow step, a README). If you can't verify a command, don't include it. - AGENTS.md has no required schema — don't force every common-sections-checklist heading into every repo. Include only sections that reflect something real about this repo; a thin, accurate file beats a padded, generic one.
- Nested placement is for genuinely different conventions, not convenience. Only create a subdirectory AGENTS.md when that subtree has its own build tool, stack, or conventions distinct from the root — otherwise you're duplicating content the root already covers, which the nearest-file-wins rule doesn't merge back together.
- This skill never touches CLAUDE.md,
.cursor/rules/*.mdc,copilot-instructions.md, or similar provider files directly — that'sprovider-adapter-author's job. Detect and hand off; don't reconcile it yourself. - This skill never audits on its own judgment — the closing
agentsmd-auditinvocation is mandatory, not optional, even when the change looks trivial.
Step 1 — Explore the target repo
Before writing anything, gather real facts: package manager and scripts (package.json, pyproject.toml, Cargo.toml, etc.), a Makefile or task runner, CI config (.github/workflows/, etc.) for the commands it actually runs, linter/formatter config files, and any existing docs (README.md, existing AGENTS.md) describing conventions. Note whether any subdirectory looks like its own package with a different stack.
Step 2 — Decide placement
- No
AGENTS.mdat the repo root yet → create one there first, covering whole-repo conventions. - A subdirectory has materially different build/test tooling or conventions than the root → create or update a nested
AGENTS.mdthere, scoped to what's different. Don't repeat root-level content — the nearest-file-wins rule means the nested file is read alone, not merged with the root. - Otherwise → update the existing file(s) in place.
Step 3 — Write or update
Use only sections that reflect something real about the repo — never fill in every common-sections-checklist heading just because it exists. Read references/content-guide.md for section-by-section guidance, a worked example, and what separates useful content from generic padding, before writing.
Step 4 — Check for an existing provider file
Look for CLAUDE.md, .cursor/rules/*.mdc, .github/copilot-instructions.md, or similar in the target repo. If one exists and now duplicates content the AGENTS.md you just wrote/updated already owns, invoke the provider-adapter-author skill on it to reconcile — don't rewrite it yourself.
Step 5 — Audit and report
Invoke the agentsmd-audit skill directly on the AGENTS.md file(s) you just wrote or updated. Resolve any FAIL findings before considering the work done — re-invoke this skill's own writing steps to fix them, then re-run the audit, same as any other close-the-loop check. Report what was created/changed, whether a provider file was reconciled, and the audit's final result.
