Use the bare, **unnamespaced** names. The `<plugin>:` form (`gitea:gitea-prs`) also still resolves, because user-scope native installs were left enabled on purpose (ADR-0018) — a working namespaced call is not evidence that anything is broken and is not something to "fix". Prefer the bare name anyway: it is what `apm install` deploys, and what survives those user-scope installs eventually being converted.
Use the bare, **unnamespaced** names. That is what `apm install` deploys and the only form this repo's own install produces — a project skill has no plugin to prefix (ADR-0018). Whether the `<plugin>:` form (`gitea:gitea-prs`) also resolves depends on native plugin installs at user scope, outside this repo; write the bare name either way.
Fall back to raw shell only when no skill covers it.
## Session rules
- **Do not add repo-owned keys to `.claude/settings.json`.** apm treats it as its own deployed artifact and `apm audit --ci` replays the install and diffs, so anything apm would not have written is permanent drift that fails the `apm-audit-ci` pre-push hook. A hook you want here is authored in `plugins/<name>/.apm/hooks/` and deployed by apm, never hand-written into that file. Machine-specific settings go in the gitignored `.claude/settings.local.json`; shared enforcement goes in `.pre-commit-config.yaml`.
- **Do not add repo-owned keys to `.claude/settings.json`.** apm treats it as its own deployed artifact and `apm audit --ci` replays the install and diffs, so anything apm would not have written is permanent drift that fails the `apm-audit-ci` pre-push hook. A hook you want here is authored in `plugins/<name>/.apm/hooks/` and deployed by apm, never hand-written into that file. The `SessionStart` entry already in it is exactly that: kyberforge authors it in `plugins/kyberforge/.apm/hooks/hooks.json` and apm merges it in, so it is apm's own output, it is what the replay expects, and it belongs in the commit — do not strip it (ADR-0019). Machine-specific settings go in the gitignored `.claude/settings.local.json`; shared enforcement goes in `.pre-commit-config.yaml`.
- **`apm.lock.yaml` turning up modified is expected, not a bug.** kyberforge's `SessionStart` hook runs `apm outdated` at startup and `apm update --yes` when something is behind, which rewrites the lock. Commit or discard it deliberately.
- **A `.apm/` edit is not live in this session until it is pushed.** The six dependencies resolve from the holocron remote, unpinned against the default branch. `apm install` deploys from the lock; `apm update` is what re-resolves refs.
- **The ADR-0020 skill gates ship hot, with no baseline.** 26 of 39 descriptions and 9 of 39 bodies exceed their FAIL tier, and the `Kyberforge.CompositionNote` Vale rule fires 10 errors across `gitea-issues`, `gitea-labels-milestones`, `gitea-prs` and `gitea-workflow`. Editing any of those skills *for any reason* means retrofitting it to the contract first — a one-line fix cannot be committed until the skill complies. Deliberate; tracked as Gitea issue #99. `skill-size-check` will not warn you about the Vale half, so check both: `pre-commit run --all-files`.
- **Run `bash tests/run-tests.sh` before considering any change done.**
- **Run `bash tests/run-tests.sh --strict` before considering any change done.** Keep the flag: without it a suite whose dependency is missing exits 77 and is counted SKIPPED rather than failed, so the run goes green having verified less than it claims.
- **Before pushing, run the whole gate locally:** `pre-commit run --hook-stage pre-push --all-files`. Pushing runs 14 repo-defined hooks, not just the test suite.
- **Pushing without a network** needs `SKIP=apm-marketplace-check,apm-pack-check-clean git push` — those two resolve a remote marketplace entry via `git ls-remote`. Skip only those two; the rest are real local checks, and adding one to `SKIP` disarms it silently.
- **Author commits with `git-commits`** — it validates Conventional Commits, which `commit-msg` enforces.

**Graduation rule:** When three or more entries cover the same pattern, the human reviews and promotes it to the appropriate standing location: `CONTEXT.md` for domain-level principles, `core/instructions/coding.md` for coding conventions, `core/instructions/testing.md` for testing conventions, or `core/instructions/subagent-orchestration.md` for delegation conventions. Those four are the whole set — `core/instructions/` holds `coding.md`, `governance.md`, `subagent-orchestration.md` and `testing.md`, and nothing else. Git conventions have no standing file of their own: promote them to `core/instructions/coding.md`, or create a new instruction file deliberately rather than assuming one exists.

**Correction (2026-08-17): the evidence under the correction above is gone, and the claim goes with
it — not to its opposite.** Observed on this machine: `~/.claude/plugins/installed_plugins.json` is
`{"version": 2, "plugins": {}}`; there is no `enabledPlugins` key anywhere in `~/.claude.json`
(`grep -c enabledPlugins` returns 0); `~/.apm/marketplaces.json` is `{"marketplaces": []}`. The
`holocron` entry in `~/.claude/plugins/known_marketplaces.json` survives, but a registered
marketplace is not an installed plugin. So the user-scope installs the 2026-08-14 correction cited
are not there, and neither is the state the *original* consequence described before it. The claim
about the namespaced form has now been written twice off two different observations of the same
machine, and this ADR has already reversed itself once on it. That is the finding: the fact is
machine state, not a property of this decision, and it changes without any commit. No instruction
file — `AGENTS.md`, `CONTEXT.md`, or a skill body — should assert either way whether
`<plugin>:<skill>` resolves. The rule that survives every observation is the one that was always the
actionable half: write the bare name, because it is the only form `apm install` produces.
**apm owns `.claude/settings.json`.** (ADR-0019 supersedes the "exactly `{"hooks": {}}`" claim
