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`.

## Skill and agent context gates (ADR-0020)
The `skill-size-check` pre-commit hook, scoped to `^plugins/[^/]+/\.apm/skills/[^/]+/SKILL\.md$`,
runs `scripts/skill-size-check.sh`. That scope means it never lints the
`plugins/kyberforge/docs/research/examples/` reference skills. It is also shipped to external repos
as `kyberforge-skill-size-check` (see
runs `scripts/skill-size-check.sh`. It is also shipped to external repos as
`kyberforge-skill-size-check` (see
[External consumers](#external-consumers-the-root-pre-commit-hooksyaml)).
**Two things fall outside that scope, both deliberately.** The `[^/]+/SKILL\.md$` tail admits only a
`SKILL.md` sitting directly in a skill directory under `.apm/skills/`:
- the `plugins/kyberforge/docs/research/examples/` reference skills, which are vendored upstream
corpus and not this repo's to gate;
- `plugins/kyberforge/.apm/skills/skill-author/assets/templates/SKILL.md` — inside `.apm/skills/`,
but two directories deeper. It is the `FILL IN:` scaffold `skill-author` copies, so its
`description: >` is a comment block rather than a description and every ADR-0020 measurement over
it would be meaningless. A reader adjusting the pattern needs to know it is there.
Everything else it matches exactly, with nothing over- or under-caught. Re-derive both halves:
```
git ls-files | grep -cE '^plugins/[^/]+/\.apm/skills/[^/]+/SKILL\.md$' # the real skills
git ls-files | grep -E '^plugins/[^/]+/\.apm/skills/.*SKILL\.md$' \
| grep -vE '^plugins/[^/]+/\.apm/skills/[^/]+/SKILL\.md$' # the scaffold only
```
The first count equals the number of skill directories (`ls -d plugins/*/.apm/skills/*/ | wc -l`);
the second returns exactly the template. The remaining unmatched `SKILL.md` files in the tree are the
generated flat mirror, which is excluded by the `.apm/` segment on purpose — a mirror edit is drift,
not an authoring change.
### `skill-frontmatter`, the other hook on that scope
A second `repo: local` pre-commit hook, `skill-frontmatter`, runs on the **same** `files:` pattern at
the same stage. It is a short shell loop: for each file, `grep -q "^name:"` and
`grep -q "^description:"`, failing with "missing required frontmatter fields" if either is absent.
**It overlaps ADR-0020's "description present and non-empty" FAIL, and the overlap is not clean.**
The ADR (`:95-101`) requires that question be decided on the **YAML-folded value** and nowhere else,
precisely because a line regex gets it wrong in both directions. Measured on fixtures:
| Frontmatter | `skill-frontmatter` | `skill-size-check` |
|---|---|---|
| `description:` with no value, then `model: sonnet` | passes — the key is on a line | ERROR, "missing or empty" |
| `"description": …` (quoted key, valid YAML) | **fails** — `^description:` does not match | passes, description read normally |
So the grep is not a second opinion on presence. It is blind to the shape ADR-0020 was written
against, and it is the only one of the two that objects to a quoted key. Neither disagreement is
currently live in the corpus, and the honest reading is that presence is `skill-size-check`'s
question — the grep's contribution to it is noise on one shape and silence on the other.
What the grep does add is the `name:` key, which **no** ADR-0020 check reads: a `SKILL.md` with no
`name:` passes `skill-size-check` at exit 0. That is its real and only unique coverage, and the
reason not to fold it into the size gate on the grounds of redundancy.

never reaches the check at all, being a compound modifier rather than a terminal name. The
SUGGESTION text says how to opt in — write it as `/name` or `-> name` and it gets checked properly.
**Known gap: the arrow form only works for hyphenated names.** Target extraction is built on
`NAME_HYPH` (`scripts/skill-size-check.sh:543`), which requires at least one hyphen, and
`ARROW_BOUNDARY` (`:561`) inherits that. So `-> gitea-prs` is extracted and checked, while
`-> triage` is not extracted at all — no ERROR, no SUGGESTION, exit 0. The unicode arrow `→` is not
recognised in either case. This makes the SUGGESTION's own advice unsafe for a single-word skill:
taking it silences the finding rather than checking it. `/name` has no such restriction and is the
form to prefer. Tracked as a defect; `tests/test-adr0020-targets.sh` has one arrow case and its
target happens to be hyphenated, so nothing currently covers this.
**The two promotion conditions are not symmetric, and the order matters.** `_add()` decides
**notation first**: when the name is written `/name`, or reached through any arrow form, the target
is marked error-eligible there and the terminal test is never run. Terminality gates only the *bare*
path — a name in prose earns its error from corroboration, and a compound modifier can never dangle.
Reading the row as "terminal AND (notation OR corroborated)" gets the notation half backwards: it
predicts that `` … Do not use for Y — use /no-such-skill afterwards. `` is a SUGGESTION, because
`afterwards` is a follower outside `FOLLOWER_OK`. It exits 1. That was the defect — `-> name` reached
`_add()` with `strict=True` from both its call sites and `/name` did not, so the one spelling
ADR-0020 offers an author who wants a route checked unconditionally was the one spelling a stray
follower could silence.
**Known gap: a BARE arrow target must be hyphenated.** Target extraction is built on `NAME_HYPH` in
`scripts/skill-size-check.sh`, which requires at least one hyphen, and `ARROW_BOUNDARY` inherits
that. So `Not X -> gitea-prs` is extracted and checked, while `Not X -> triage` yields no target.
The exclusion is deliberate, not an oversight: `research`, `triage`, `forge`, `prototype` and `tdd`
are all real skill names *and* ordinary English, so a bare single-word rule would flag most of the
corpus. The marked spellings carry no such restriction — `` `triage` `` and `/triage` are both
extracted — and are the forms to prefer. **Both arrow spellings are recognised:** `ARROW_MARKED`,
`ARROW_BOUNDARY` and `BOUNDARY_ARROW` are each built from `(?:->|→)`, so the unicode arrow `→`
behaves exactly like `->` in every case below. Cite these constants by symbol name, never by line
number: the script moves often enough that a pinned line lands a reader in an unrelated comment
block and reads as plausible.
**The gap is no longer silent.** It used to be exactly that — no ERROR, no SUGGESTION, exit 0 — which
made the dangling-target SUGGESTION's own advice unsafe for a single-word skill: taking it silenced
the finding instead of checking it. `boundary_clause_status()` now separates the case out and
reports it as `unparsed` (see below), naming the parse failure and the two spellings that fix it.
The target is still not *resolved*; the author is now told so rather than left with a green gate.
`tests/test-adr0020-targets.sh` covers both directions (`arrow-single-word-target` and the silent
control `arrow-single-word-marked`).

`.claude/` or `.agents/` anywhere, produced findings identical to the working tree. The figures that
reproduction recorded — 26 description FAILs, 9 body FAILs, 2 dangling targets, 0 missing references
— are the pre-retrofit corpus as it stood when the experiment was run, kept here as the evidence for
the install-independence claim. They are not current: the retrofit under #99 took the first three to
zero. What the experiment establishes is that the two trees agree, not what either measured.
### Boundary-clause detection: three outcomes, not two
`boundary_clause_status()` returns one of three values, and the two findings get separate messages:
| Status | When | Reported as |
|---|---|---|
| `present` | a prose marker (`do not`, `instead`, `rather than`, `not for`) or an arrow clause was found | nothing |
| `absent` | neither was found | SUGGESTION: add a boundary clause, in either form |
| `unparsed` | an arrow clause was found and **no target could be read out of it** | SUGGESTION: the clause is present — this is a *parse* failure, not a missing clause |
The third had to be split out. Collapsing it into `absent` is a **wrong** finding, not a strict one:
it sends the author to add a clause that is already there. Three of them instead reworded a correct
clause until the regex accepted it, one stripping the very filename that discriminates the skill
from its neighbour (**#110**).
`unparsed` is narrow and certain on purpose. It fires only on the arrow form, which *always* names a
target, so zero targets means the name is written in a shape the extractor cannot see — in practice
a bare single-word target, per the known gap above, and the message says to write it `` `name` `` or
`/name`. A **prose** clause yielding no target is not reported at all: "Do not use for anything else"
is a complete and legitimate boundary clause that names nowhere to go.
**One arrow, one target.** An arrow clause naming two or more targets draws its own SUGGESTION,
quoting both names and asking for a split, because only the first is ever resolved: the conjunction
continuation (`CONT_MARKED` / `CONT_ANY`) is wired to the prose route verbs and never to arrows. So
`Not X -> a or b` resolved `a`, left `b` resolved by nothing and reported by nothing, and then let
the audit print "1 of 1 boundary target(s) resolve" on a clause naming two — a gate under-reporting
its own coverage, which is the one failure mode ADR-0020 says a gate must not have (**#107**). The
clause is **rejected rather than the arrow scan extended**: extending it would widen the resolver's
deliberately conservative false-positive tuning across every arrow in the corpus, where splitting
costs the author one full stop. The convention is one arrow per target — `Not X -> a. Not Y -> b.` —
already what every retrofitted `gitea-*` skill does in practice, now stated in
`skill-author`'s `references/contract.md` instead of being folklore.
**Dotted filenames in a boundary clause now parse.** `CLAUSE_BODY` — what may sit between `Not` and
the arrow — used to be `[^.;]`, a class that cannot cross a `.`, so every clause naming a dotted
filename between the two (`AGENTS.md`, `.vale.ini`, `.pre-commit-config.yaml`) was invisible to both
`BOUNDARY_ARROW` and `ARROW_BOUNDARY`. The two resulting failures were different sizes (**#110**):
- with a **backticked** target the clause was *misdiagnosed*. The backtick sweep still extracted the
target, so the route was checked, but the gate reported "no boundary clause" on a clause that was
present and working. That is the misdiagnosis the three rewordings above came from.
- with a **bare** target the clause was *unchecked*. `ARROW_BOUNDARY` is the only extractor for a
bare arrow target, so `Not AGENTS.md -> no-such-skill` produced no target, no dangling report and
no missing-clause SUGGESTION. Silence, not noise — the worse of the two.
`CLAUSE_BODY` is now `(?:[^.;]|\.(?=\S))`: a dot inside a filename is followed by a non-space, a
sentence-ending dot by whitespace or end of string, so the class crosses `AGENTS.md` and still stops
at a real sentence end. **Read the second bullet forward as well as back:** a bare target sitting
after a dotted filename is now extracted, resolved, and a blocking ERROR when it dangles, where the
same clause used to pass unchecked in silence.
### SUGGESTION-only checks
Three more, deterministic to measure but judgment to act on:
Deterministic to measure, judgment to act on:
- a description with **no boundary clause at all**;
- a description with **no boundary clause at all** (`absent`);
- an **arrow clause whose target could not be read** (`unparsed`);
- an **arrow clause naming more than one target**;
- a `## Gotchas` section with **more than five entries**;
- a `## Gotchas` section over **25% of the body**.
### Hand-invoked skills are exempt from the routing rules, and only those
A skill or agent whose frontmatter carries `disable-model-invocation: true` skips three checks:
- the boundary-clause check, `absent` and `unparsed` alike;
- the multi-target arrow check;
- the 250-character description **target** (`hand_invoked()` in `scripts/skill-size-check.sh`).
It keeps the 400-character description FAIL and **both** body word tiers, and if its description
does happen to name a target, that target is still resolved and can still dangle.
Why the exemption is right: `disable-model-invocation: true` removes the skill from the
model-visible listing entirely — it is not preloaded, and the Skill tool refuses to call it — so its
description is never matched against user intent. ADR-0020 and `skill-author`'s contract therefore
give such a skill **one plain human-facing sentence**: no trigger list, no boundary clause. No
validator knew the field existed (**#108**), so the boundary-clause SUGGESTION fired on exactly the
shape the contract mandates, and its remedy — "so the router knows where NOT to send this skill" —
was addressed to a router that cannot see the skill at all. An author who followed the advice made
the file worse. There is no router to inform.
The half that does **not** lift is the point. The body is still loaded on invocation and still
competes with the caller's live conversation, so neither body tier moves. The 400-character ceiling
stands too: a hand-invoked description is not preloaded, but it is still the one line the user reads
when choosing from the `/` menu, and that ceiling is an outlier stop rather than a routing-quality
budget — which is precisely why the 250-character target is the tier that lifts.
The field is read as a **boolean**, not as a mention of the key. PyYAML already resolves the
unquoted YAML 1.1 booleans, so the extra handling catches a quoted `"true"`, which a host reads as
truthy; `disable-model-invocation: false` is the model-invoked case written out longhand and buys
nothing. A frontmatter parse failure returns false rather than raising — the flag is a *modifier* on
other checks, and `description_value()` on the same text already reports the broken frontmatter, so
raising here would diagnose one file twice two different ways.
`caveman` and `zoom-out` are the two carriers here. `tests/test-skill-size-check.sh` pins both
halves — what the carve-out lifts, each with a flag-removed control, and what it must not.

nothing; only the two FAIL tiers, the dangling-target ERROR and the missing-`references/` ERROR do.
Read the count as a work queue, and the FAIL columns above as the gate.
`Kyberforge.CompositionNote` is the ADR-0020 Vale rule banning composition and architecture prose

those four skills means fixing its prose findings as well as its size findings.

that reintroduces one blocks the commit even though no skill carries one today.
Consequence: editing a non-compliant skill *for any reason* means retrofitting it to the contract
first — a one-line fix to `gitea-prs` cannot be committed until that skill complies. This is
deliberate; it guarantees convergence and avoids a half-state. Tracked as Gitea issue **#99**.
Because nothing is grandfathered, the gates now bite on **first commit**: a new skill, or an edit
that pushes a description past 400 characters or a body past 900 words, is blocked until it
complies. That is the steady state the retrofit was for — it is no longer true that an unrelated
one-line fix to a skill requires retrofitting that skill first.

### The blind spot: `references/` is unlinted, for two independent reasons
Every `references/*.md` file in the corpus is outside the prose gate. Count them with
`git ls-files | grep -cE '^plugins/[^/]+/\.apm/skills/[^/]+/references/.*\.md$'` rather than reading
a figure here; it moves with every retrofit. This is the gap that matters most, because the context
contract's own remedy for an over-long body is to move prose **into** `references/` — the gate pushes
text across its own boundary and then stops watching it.
**Closing either cause alone changes nothing.** There are two, and they are independent:
| Cause | Where | Effect on a `references/` file |
|---|---|---|
| the `Kyberforge` style is scoped `[**/SKILL.md]` | `skill-audit/assets/vale/.vale.ini` | matches no section, so Vale lints 0 files and exits 0 |

Verified both ways. Handing skill-audit's `vale-wrap.sh` a reference file directly — bypassing
pre-commit entirely, so only the style scope is in play — prints `0 errors … in 0 files` and exits 0,
where the same wrapper on a `SKILL.md` reports `in 1 file`. And the hook's `files:` regex, applied to
`git ls-files`, selects only the skill-directory `SKILL.md` files scoped at the top of this page, so
pre-commit never hands Vale a reference file to begin with. Widening the glob to `[**/*.md]` would
still lint nothing through the hook; widening the hook's `files:` alone would hand Vale files its own
config declines to match, which is the [0-file NOT RUN](#a-0-file-vale-run-is-not-run) shape — a
green run that measured nothing. **Issue #117** records the style-scope half; the hook half has to
land in the same change or the fix is cosmetic.
The consumer manifest is a third axis and does not rescue this either: `.pre-commit-hooks.yaml`'s
`(^|/)SKILL\.md$` is layout-agnostic but still filename-shaped, so an external repo running
`kyberforge-vale-audit-skill` has the same gap.
### `vale-wrap.sh`, never bare `vale`
Both audit skills' Step 1 and both pre-commit hooks call **each copy's own**
