refactor(skills): retrofit the corpus to the ADR-0020 context contract (#129)

Browse Source 
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`.

## Gotchas
- `rev` must be an immutable tag or commit SHA — never a branch name. `pre-commit autoupdate` breaks silently on branches.
- Fixers (`trailing-whitespace`, `end-of-file-fixer`, `pretty-format-json`) modify files but do NOT auto-stage them. The commit is blocked; the user must re-stage and recommit. Warn when adding fixers.
- `pre-commit validate-config` catches YAML structure errors but does NOT check whether hook `id`s exist in the target repo's manifest, and does NOT download or run hooks. It is fast; run it after every write.
- When removing a hook leaves its repo block with zero hooks, delete the entire repo block — an empty `hooks: []` causes `validate-config` to fail.
- `language: system` and `language: script` are deprecated names. Use `language: unsupported` and `language: unsupported_script` for new local hooks.
- `rev` must be an immutable tag or commit SHA, never a branch name. A branch looks like it works and then breaks `pre-commit autoupdate` silently.
- `pre-commit validate-config` checks YAML structure only — it never confirms a hook `id` exists upstream, so a config it accepts can still fail on first use.
## Route
Check before acting:
| Condition | Flow | Read |
|---|---|---|
| No `.pre-commit-config.yaml` in the repo | Create | `references/create-config.md` |
| `.pre-commit-config.yaml` exists | Modify | `references/modify-config.md` |
- `.pre-commit-config.yaml` does not exist → **Create from scratch**
- File exists → **Modify existing**
Read only the file matching the resolved flow — each is self-contained.
## Create from scratch
The target is always `.pre-commit-config.yaml`, the config that consumes hooks. A request to publish hooks for other repos to consume means `.pre-commit-hooks.yaml`, a different file this skill does not author.
1. Run a shallow extension scan:
```bash
git ls-files | grep -oE '\.[a-z]+$' | sort | uniq -c | sort -rn
```
2. Read `references/hooks-by-language.md` to map detected extensions to recommended hooks. For a minimal starting point instead of a full recommendation set, `pre-commit sample-config > .pre-commit-config.yaml` prints a small starter config to build on.
3. State the proposed config in full before writing. Wait for user confirmation.
4. Write `.pre-commit-config.yaml`.
5. Run `pre-commit validate-config`. If non-zero: show the error, fix it, re-validate. Never leave a broken config.
## Gates common to both flows
## Modify existing
Read `.pre-commit-config.yaml` first. Note any stale `rev` values (see **Rev staleness** below) but do not change them.
### Adding a hook
1. Run a shallow extension scan to detect languages in the repo:
```bash
git ls-files | grep -oE '\.[a-z]+$' | sort | uniq -c | sort -rn
```
2. Read `references/hooks-by-language.md` for the correct repo URL, rev, and recommended args for any hook before writing.
3. Check for duplicates — if the same hook ID or equivalent tool already exists in the config, say so and stop.
4. To sanity-check a hook against the repo's actual files before committing to it in config, smoke-test it with `pre-commit try-repo <repo-url> <hook-id> --verbose` (or a local path for hooks under development). This runs the hook without writing anything.
5. If the hook's source repo already exists in the config, add the hook under that repo block. Otherwise append a new repo block.
6. State the proposed addition. Wait for confirmation.
7. Write. Run `pre-commit validate-config`. If non-zero: show error, fix, re-validate.
### Removing a hook
1. Identify the hook entry and its repo block.
2. State what will be removed: hook ID, and whether the parent repo block will also be deleted (if it would have zero hooks remaining). Wait for confirmation.
3. Remove the hook entry. If the repo block now has zero hooks remaining, remove the entire repo block.
4. Write. Run `pre-commit validate-config`. If non-zero: revert the edit, show the error, and stop — do not leave a broken config (removal edits are not safely auto-fixable, unlike a bad new hook block, which can usually be corrected in place).
### Configuring top-level keys
Only when the user explicitly asks. Valid keys: `fail_fast`, `default_stages`, `default_language_version`, `minimum_pre_commit_version`, `exclude`, `files`, `default_install_hook_types`.
State the proposed change and wait for confirmation before writing.
## Rev staleness
When reading the config, for each repo listed in `references/hooks-by-language.md`, compare its `rev` in the user's config against the rev in that file. Flag any mismatch as potentially outdated and tell the user to run `pc-run` to autoupdate. Repos not in the reference cannot be checked — skip them silently. Do not modify `rev` values yourself.
The reference table's pins can themselves go stale between updates — treat a mismatch as a prompt to check, not a certainty. `pre-commit autoupdate` (via `pc-run`) is the authoritative source for what the current rev actually is.
## Scope boundary
This skill manages `.pre-commit-config.yaml` only. It does not:
- Author `.pre-commit-hooks.yaml` (publishing hooks for external consumers)
- Run `pre-commit install`
- Execute hooks or run the test suite
- Bump `rev` values
For those operations, use `pc-run`.
1. State the proposed config or edit in full and wait for confirmation before writing. Hook choices are opinions imposed on everyone else's commit loop, not defaults to assume.
2. Run `pre-commit validate-config` after every write. On a non-zero exit, show the error and resolve it before reporting done — never leave a config that cannot be parsed.
3. Never edit a `rev` value. Report staleness and hand the bump to `pc-run`, which runs `autoupdate` against the hook repos themselves.

# Creating a `.pre-commit-config.yaml`
Reached from `SKILL.md`'s Route table when the repo has no config yet. Self-contained — the modify
flow's file is not needed here. `SKILL.md`'s three common gates still apply.
## Steps
1. Detect what languages are actually in the repo with a shallow extension scan, rather than
inferring them from the project's name or README:
```bash
git ls-files | grep -oE '\.[a-z]+$' | sort | uniq -c | sort -rn
```
2. Read `references/hooks-by-language.md` and map the detected extensions to recommended hooks.
Take the repo URL, `rev` and args from that file rather than from memory — a `rev` that does not
exist is the most common way a fresh config fails on its first run.
For a deliberately minimal starting point instead of a full recommendation set,
`pre-commit sample-config > .pre-commit-config.yaml` prints a small starter config to build on.
3. State the proposed config in full and wait for the user's confirmation.
4. Write `.pre-commit-config.yaml`, then run `pre-commit validate-config`. If it exits non-zero,
show the error, fix it in place, and re-validate.

# Modifying an existing `.pre-commit-config.yaml`
Reached from `SKILL.md`'s Route table when the repo already has a config. Self-contained — the
create flow's file is not needed here. `SKILL.md`'s three common gates still apply.
Read the existing `.pre-commit-config.yaml` before editing. Note any stale `rev` values (see
**Rev staleness** below) but do not change them.
## Adding a hook
1. Run a shallow extension scan, so the addition is judged against the languages actually present:
```bash
git ls-files | grep -oE '\.[a-z]+$' | sort | uniq -c | sort -rn
```
2. Read `references/hooks-by-language.md` for the correct repo URL, `rev` and recommended args
before writing anything.
3. Check for duplicates. If the same hook ID, or an equivalent tool, is already configured, say so
and stop rather than adding a second one.
4. To sanity-check a hook against the repo's real files before committing to it, smoke-test it:
```bash
pre-commit try-repo <repo-url> <hook-id> --verbose
```
Use a local path in place of the URL for a hook under development. This runs the hook without
writing anything.
5. If the hook's source repo is already a block in the config, add the hook under that block.
Otherwise append a new repo block.
6. State the proposed addition, wait for confirmation, write, and run `pre-commit validate-config`.
On a non-zero exit, show the error, fix it, and re-validate.
## Removing a hook
1. Identify the hook entry and its parent repo block.
2. State what will be removed — the hook ID, and whether the parent repo block goes with it because
it would be left with zero hooks. Wait for confirmation.
3. Remove the hook entry. If the repo block now has no hooks left, remove the whole block: an empty
`hooks: []` fails `validate-config`.
4. Write, then run `pre-commit validate-config`. On a non-zero exit, **revert the edit**, show the
error, and stop. A removal is not safely fixable in place the way a malformed new hook block is,
so recovering the prior state beats patching forward.
## Configuring top-level keys
Only when the user explicitly asks. Valid keys: `fail_fast`, `default_stages`,
`default_language_version`, `minimum_pre_commit_version`, `exclude`, `files`,
`default_install_hook_types`.
State the proposed change and wait for confirmation before writing.
## Rev staleness
For each repo in the config that also appears in `references/hooks-by-language.md`, compare the
two `rev` values. Flag a mismatch as potentially outdated and tell the user to run `pc-run` to
autoupdate. Repos absent from the reference cannot be checked — skip them silently. Do not modify
any `rev` yourself.
The reference table's own pins go stale between updates, so treat a mismatch as a prompt to check
rather than proof of staleness. `pre-commit autoupdate`, via `pc-run`, is the authoritative answer
to what the current `rev` actually is.
