The clean provenance bill was an artifact. Checks 7 and 8 assume `Research doc:` names a source index whose H2s are slugs, but 30 of 121 corpus entries point at topic content documents whose H2s are topics. Those 30 produced every new check-7 INFO — all false positives. Check 8 aimed at the same documents, which carry no `Status:` line at all, would have emitted a large false-FAIL flood; the only thing preventing it was an unannounced `rd_status != extracted` skip. So "0 new FAILs" rested on exactly the fail-open class this branch exists to remove, and naively fixing the skip would have turned the branch red. Checks 7/8 now run only when the research doc's basename is `sources.md`, and every other case emits a visible INFO naming the slug. The dangling-path INFO stays ahead of the basename gate, because a path that does not resolve is rot whatever it is named. `parse_status` accepts the bullet form and a trailing note after the backticked value, so a status it cannot read no longer reads as "nothing to check". Corpus: 36 INFOs of which 30 were false, to 56 of which none are. FAIL stays 0, and no Status line flipped to `extracted` under the new parser, so no FAIL was suppressed by luck. Also closed, each a silent pass: a nonexistent directory, a directory with no SKILL.md, and extra arguments now exit 2; a UTF-8 BOM no longer defeats frontmatter parsing; the bare `except Exception: return False` that turned an unreadable file into a clean pass is gone, with all reads pinned to UTF-8; check 3 walks nested `references/` subdirectories; `FILL IN:` at end of line no longer escapes checks 1 and 6; duplicate `## slug` blocks and repeated `Research doc:` lines are announced rather than half-read. The agent-audit copy carried all of the above unfixed and is now ported, minus the four fixes that are genuinely N/A at agent scope — it reads a plugin-root `sources.md` and has no checks 7/8 and no `references/` tree. Its silent exit 0 for a file outside plugin scope is preserved deliberately: that is a verdict about a valid file, not a skip, and `check-scope-walkup-sync.sh` pins it. Every exit-2 gate therefore decides from the argument alone, before the walk-up runs. `validation-scripts.md` said flatly that silence from the validator is a pass, not a skip. That sentence is what made a typo'd path dangerous, and both copies are corrected here. The matching SKILL.md exit-code guidance lands with the audit rubric change, which touches the same files. Tests: skill-audit 45 to 65, agent-audit 24 to 43, every new case proven by mutation. Refs: #111, #118, #121
skill-audit
Audit a skill directory against the agentskills.io specification and the house context-budget contract (ADR-0020). Runs structural validation then a qualitative review across description quality, body discipline, patterns, formatting, file structure, scripts, and internal consistency, plus a provenance chain check.
What it does
- Runs
scripts/validate.shandscripts/validate-provenance.shfor structural and provenance checks, plusscripts/vale-wrap.sh— a Vale prefilter that deterministically flags non-imperative description openers, composition and architecture notes, vague wording, padding phrases, and "There is/are" sentence openers - Reads all files in the skill directory
- Applies qualitative checks across five dimension groups — always loading
references/finding-criteria.md, then one rubric fromreferences/per group the criteria put in play - Outputs a compact findings report — findings only, grouped by dimension, each with Why and Fix — and a result block with handoff to
skill-author
validate.sh enforces two independent length families that must not be conflated: the agentskills.io spec conformance ceilings (500 lines, 2,770 words, both counting the whole file) and the ADR-0020 context budget (250/400 description characters, 600/900 body-only words).
Alongside those it runs four shape checks that are not length measurements at all. Two are FAILs: every routing target named in the description — in the compressed Not <thing> -> <name> arrow and in the prose form — must resolve to a real skill or agent, and every references/<file>.md the body names must exist on disk. Three are SUGGESTIONs: a missing boundary clause, a Gotchas section over five entries, and a Gotchas section over 25% of the body. The resolution universe for boundary targets is derived by walking up from the audited SKILL.md — the authoring root above it, its own apm package, and that package's declared apm.yml dependencies — so a fresh clone and a machine that has run apm install return the same verdict. When no universe can be determined the check prints INFO ... DID NOT RUN and does not silently pass.

Files
| File | Purpose |
|---|---|
SKILL.md |
Skill instructions for agents |
scripts/validate.sh |
Structural validator — checks name format, name matches directory, description presence and length, body-only word count, line and whole-file word ceilings, boundary-clause presence, boundary-target resolution, references/ pointer existence, Gotchas entry count and body share, placeholder detection, script executable bit, and interactive-prompt detection |
scripts/validate-provenance.sh |
Provenance validator — checks sources.md completeness, source_keys/slug consistency, Contributing files existence, bidirectional linkage, Research doc: fields, and upstream research doc alignment |
scripts/vale-wrap.sh |
Vale prefilter wrapper — runs the bundled Kyberforge Vale styles against SKILL.md and reports alerts as deterministic FAILs ahead of Step 3's qualitative review |
assets/vale/.vale.ini |
Vale configuration — points Vale at the bundled Kyberforge style path, self-located relative to vale-wrap.sh |
assets/vale/styles/Kyberforge/CompositionNote.yml |
Vale rule — flags composition and architecture notes in a description (e.g. "cross-cutting", "entry point", "rather than duplicating") |
assets/vale/styles/Kyberforge/DescriptionOpener.yml |
Vale rule — flags non-imperative "This..." description openers |
assets/vale/styles/Kyberforge/PaddingPhrase.yml |
Vale rule — flags generic "see references/" padding phrasing in conditional references |
assets/vale/styles/Kyberforge/SentenceOpenerThereIs.yml |
Vale rule — flags body sentences starting with "There is"/"There are" |
assets/vale/styles/Kyberforge/VagueWording.yml |
Vale rule — flags known filler wording (e.g. "helps with", "utilize") |
references/finding-criteria.md |
Every dimension's FAIL and SUGGESTION criteria — the one Step 3 file loaded on every run; it decides which rubrics below are worth loading |
references/description-quality.md |
Rubric for the description dimension — three-part shape, the 250/400-character budget, the hand-invoked (disable-model-invocation) contract, and the internal-mechanics FAIL |
references/body-discipline.md |
Rubric for the body-discipline dimension — the core test, the 600/900 body-only budget against the 2,770-word whole-file backstop, the mandatory-dispatch rule, and the Gotchas constraints |
references/patterns.md |
Rubric for the patterns dimension — which instruction construct fits which job, and how each is correctly formed |
references/file-structure.md |
Rubric for the file-structure and internal-consistency dimensions — permitted directories, cross-plugin path rules and their two structural exemptions, README drift |
references/formatting-and-scripts.md |
Rubric for the formatting and scripts dimensions — heading and fencing conventions, and the agentic-use criteria for bundled scripts |
references/validation-scripts.md |
Step 1 troubleshooting — the manual structural fallback when validate.sh cannot run, and the script exit codes that are easy to misread (loaded only on a script failure) |
references/sources.md |
Provenance record — agentskills.io sources that informed this skill and which files each contributed to |
tests/validate.bats |
(source-only) Bats test suite for validate.sh |

(source-only) Bats test suite for validate-provenance.sh |

Rows marked (source-only) exist in the authoring source (.apm/skills/skill-audit/) but are
not present in an installed plugin: scripts/sync-plugin-content.sh strips
<category>/<name>/tests when it generates the flat mirror, because these are dev-time fixtures no
plugin host needs to discover (ADR-0017). Run them from a repo checkout, not from an install.
