Six defects, each one a place where two files that an author reads in the same sitting told them different things — or where the trim dropped a rule and nothing noticed because no gate covers prose. **"Use proactively" contradicted itself across the pair.** All three agent templates said to add it where the runtime should delegate unprompted, while `agent-audit`'s `KyberforgeCopilot.ProactivePhrase` rule grades it a hard FAIL in any `*.agent.md` — which is the Copilot half of every project/user pair *and* the vendor-neutral plugin-scope file, since that compiles to a real Copilot agent downstream. Following the template produced a file the repo's own gate rejects. The phrase is now permitted in exactly one place, the Claude Code `.md`, and `references/contract.md` carries the per-file table plus the consequence authors ask about next: a pair whose CC half has it and whose Copilot half does not is correct, because `agent-audit` checks that both halves describe the same job, not that they match word for word. **The output-schema rule contradicted itself inside one file.** `contract.md` said any content only one branch reaches moves to `references/`, and then offered an "Output format template" body pattern with no qualification. Stated once now, so it is not re-litigated: an output schema stays in the body only when every flow produces it and it is roughly 50 words or less. No third option. **Gotchas tiers disagreed with the script.** `validate.sh` emits the entry count through `suggest()` and exits 0, while `skill-author` and `skill-audit` both called more than five entries a FAIL. Whether a given gotcha earns its place is judgment, so the prose moves to the script's tier rather than the reverse. The paraphrase rule stays a FAIL and is explicitly marked as the auditor's call — no script detects it. **The dispatch exemplar was cited at the wrong number.** `apm-workflow`'s body is 421 words; 554 is its whole-file count. Both `contract.md` and `body-discipline.md` cited 554 while describing a body budget, so an author calibrating against the exemplar overshot by ~30% — the exact whole-file/body-only conflation those two sections exist to warn against, reproduced inside the warning. **"Error handling" came back as a required body element.** It was one of four and is the one that gets dropped, and dropping it is not neutral: an agent handed malformed input with no instruction invents a recovery, and a subagent's invented recovery is invisible to its caller until the output is wrong. Restored in `agent-audit`'s rubric as a SUGGESTION, in `agent-author`'s contract and both scope checklists as a required element, and as an `## Errors` section in all three templates. **`skill-author` Step 4 gains the one check the audit misses.** An empty body reports `PASS SKILL.md body word count 0` — a word gate cannot tell "concise" from "absent". Step 4 now hand-checks for a non-empty section, and its commit verification is conditioned on actually being inside a git worktree, which a skill under `~/.claude/skills/` is not. Also here: absolute repo paths removed from `skill-author`'s SKILL.md and contract.md in favour of naming the skill (`zoom-out`'s description is quoted inline instead of pointed at), the boundary-target universe documented to match the resolver, a two-hops-from-SKILL.md limit on reference chains, and `new-agent.sh`'s next-steps output naming the description budget and the deliberate absence of an agent body gate.

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, loading one rubric from
references/per group - 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/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 |

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.
