Claude Code AI - Gitea MCP 598a7c326a refactor(skills): retrofit the corpus to the ADR-0020 context contract (#129)
Retrofits all 39 skills to ADR-0020's description/body context contract, then fixes what six rounds of independent review found in that retrofit — including four ways the hot gate itself failed open.

Closes #99, #107, #108, #110, #111, #114, #115, #120.

## The retrofit (waves 1-5)

| | Start | Now |
|---|---|---|
| Description FAILs (>400 chars) | 26 | **0** |
| Body FAILs (>900 words, body-only) | 9 | **0** |
| Dangling routing targets | 2 | **0** |
| `Kyberforge.CompositionNote` | 10 | **0** |
| Preload tax | 21,005 chars | **~10,500** |

Under the 12,000-char success criterion. Per-wave detail is on #99.

## The review fixes

**The gate failed open four ways, three of them found after the retrofit shipped.** An unrecognised follower token made a dangling target vanish. A skill directory with no `SKILL.md` resolved as a valid target, so a commit could be green locally and red in a fresh clone — three existing fixtures were relying on that, one of which made the install-leak A/B pass vacuously. Then the free-standing `/name` sweep turned out to be gated on the sentence carrying a boundary marker, so route notation in any other sentence was invisible — not an ERROR, not a SUGGESTION, not an INFO — which left the documented "`/name` always blocks" promise false from a second direction. All four fixed and pinned.

**Two checks were silently not running.** `validate-provenance.sh` checks 7-8 were dead across nine skills. Waking them exposed a deeper problem: they assume `Research doc:` names a source index, but 30 of 121 entries point at topic content documents, so every new check-7 INFO was a false positive and check 8 was saved from a false-FAIL flood only by an *unannounced* skip. Checks 7/8 are now scoped to source indexes and every skip announces itself (#121).

**The retrofit's own anti-goal, four times.** ADR-0020 warns that a blunt gate gets satisfied by deleting content rather than relocating it. `diagnose` and `skill-audit` relocated prose and then read it unconditionally; `prototype` and `vale-config` deleted rules outright that survived nowhere. All four addressed.

## Verification

- `bash tests/run-tests.sh --strict` — 24 suites, 0 skipped, 0 failed
- `bash tests/run-bats.sh` — 325 tests, 0 failures
- `pre-commit run --all-files` — 17/17
- `pre-commit run --hook-stage pre-push --all-files` — 16/16, with `apm marketplace check` and `apm pack --check-clean` run against the remote, not skipped
- `scripts/skill-size-check.sh` over all 39 skills — rc 0, 0 ERROR/FAIL, SUGGESTION-only
- Preload tax measured at **10,498 chars**, max description 390 — both inside budget
- Every new test proven non-vacuous by a deliberate mutation of the behaviour it covers

**Per-commit sync, stated accurately:** the ten commits from the latest review round each pass `check-plugin-content-sync` in isolation, verified by checking each out in a detached worktree with a clean between. The earlier gitea window (`dfacf05..bedbd1d`, nine commits) does **not** — its mirror was regenerated in one batch at `bbc7300`. An earlier revision of this description claimed the property held for every commit; it does not, and a bisect through that window lands on a red commit. **Squash-merge** to collapse it, or accept that this range is not bisectable.

## Version bump

Six plugins and the catalog take a **patch**, not a minor. The branch is **89 commits — 40 `fix` / 30 `refactor` / 12 `docs` / 5 `chore` / 2 `test` — zero `feat`, zero `!`, zero `BREAKING CHANGE`** — and adds no skill, agent, command or hook. (Two earlier revisions of this section cited a stale histogram, most recently 78 commits; the figures above are measured at HEAD.) Both rules this repo ships (`forge/references/version-bump.md`, landing in this PR, and `git-commits/references/conventional-commits-spec.md`) make that a patch, and the catalog set is unchanged at 7 entries.

Not settled by that: four published files were removed from the installed tree, three moved, and `caveman` gained `disable-model-invocation`, retiring its old triggers. Under a strict reading those are major-class and currently ship under `refactor:` with no marker. Whether the deployed skill surface is a public contract is written down nowhere — worth deciding, but it outlives this PR.

## Deliberately not in scope

#112 (cherry-pick ownership, now resolved in favour of `git-commits`), #113 (`rtk git` normalisation), #116 (research fan-out), #101 (audit-skill merge), #122 (non-spec skill-root files), #123 (no PRD producer) stay open. #117 is the one worth reading: the contract's remedy is to move prose into `references/`, which is exactly where neither the size gate nor Vale looks — and the blind spot is wider than #117 currently records, since there is no root `.vale.ini` at all, so every ADR, `CONTEXT.md` and `README.md` is unlinted too.

That blind spot let this branch carry two `level: error` `Kyberforge.SentenceOpenerThereIs` violations into `references/` files it created — `provider-adapter-author/references/provider-matrix.md:31` and `agent-audit/references/finding-criteria.md:95`. Both are reworded in `afadaae`, confirmed by routing each file through the audit's own `vale-wrap.sh` (1 error each before, 0 after). Five further occurrences sit in `references/` files already on `main`; those are the pre-existing corpus and stay with #117, which is the real fix.

Also unfixed and not this PR's: `apm install` appends a duplicate `SessionStart` entry to `.claude/settings.json`, so a fresh clone cannot get pre-push green without an edit AGENTS.md warns against. Reproduces identically on `main`.

Use when managing Git submodules — the full lifecycle of a nested
repository inside a superproject — including phrasings that never say the
word, such as "add a dependency repo" or "vendor this repo inside ours".
Not multiple checkouts of one repo -> `git-worktrees`.
Not the superproject's own remotes -> `git-remotes`.
metadata:
category: git
source_keys:
- git-scm-submodule-docs

## Gotchas
- **`update` leaves the submodule in detached HEAD.** Branch inside the submodule before editing, or the work is unreachable once the pointer moves.
- **Push the submodule before the superproject.** The superproject stores only a SHA, and one missing from the submodule's remote breaks every collaborator's `update`.
- **`--recursive` is never the default.** Subcommands stop one level deep, so nested submodules go stale silently.
- **`git rm` leaves `.git/modules/<name>/` behind.** Nothing cleans it up, and it blocks re-adding a submodule there.
## Working rules
Run `rtk git` from the superproject root. Enter the submodule directory only for commits and pushes
that belong to the submodule's own history — the two repositories have independent histories, and
the same command from the wrong directory writes to the wrong one.
Before committing a superproject pointer, run `rtk git submodule status --recursive`. Prefixes: `-`
not initialized, `+` working tree differs from the recorded commit, `U` merge conflict. Add
`--cached` to read the SHAs the superproject index will record rather than the working-tree state.
A `-dirty` suffix means uncommitted changes inside the submodule, and committing the pointer over
them pins a state nobody else can reproduce.
To run one command across every submodule: `rtk git submodule foreach --recursive '<cmd>'`. Inside
`<cmd>`, Git sets `$name`, `$sm_path`, `$displaypath`, `$sha1` and `$toplevel`; append `|| :` to
continue past a failure instead of aborting the traversal. `$sm_path` and `$displaypath` name the
same directory from different vantage points — if which one you want is not obvious, read the
variable table in `references/setup-and-update.md` before writing the command.
## Dispatch
Read only the row that matches the request.
| Task | Reference |
|---|---|
| Clone a superproject with submodules; add, initialize, update or re-pin one; run a command across all of them with `foreach` | `references/setup-and-update.md` |
| Change where a submodule points — `sync`, `set-url`, `set-branch`, a local mirror override, `absorbgitdirs`, or any `.gitmodules` / `.git/config` key | `references/urls-and-config.md` |
| Remove a submodule, or `deinit` one without removing it | `references/removal.md` |
Removal and `deinit` are destructive: state what will be deleted and get confirmation before
executing.
## Output format
```yaml
operation: <clone|add|init|update|status|sync|set-url|set-branch|absorbgitdirs|deinit|remove>
status: <success|error|partial>
message: <one line; include git's own output on error>
