Defame1297 620f20b0fd refactor(kyberforge)!: merge skill-audit and agent-audit into factory-audit
Why

The two audit skills carried 1,724 lines of byte-identical duplication: the ADR-0020 boundary
resolver (1,061), vale-wrap.sh (526), the Vale style rules (44) and the Contributing-files parser
(93). Nothing shared them — they were held in sync by a 413-line pre-push gate and its 797-line
test suite. Sync-by-gate had already failed once: at 484357a the two parser copies drifted into
different spellings of the bullet loop while a docstring asserted they were identical. That drift
was behaviour-neutral and was re-unified by hand at 598a7c3, so the copies were identical at merge
time — but nothing had caught it, and the next drift need not be neutral.

Implementation Notes

Self-containment binds BETWEEN skills, not within one. The agentskills.io spec forbids reaching
across skill directories, which is why two separate skills needed embedded copies; two files inside
ONE skill may source a third. That is the whole reason the merge removes duplication rather than
relocating it.

The union of both bodies measured 1,532 words against BODY_MAX_WORDS=900, and only 211 of those
words were shared, so SKILL.md is a dispatch body. Step 0 resolves the flow from the target path
before any validation, and its table mirrors validate.sh's detection exactly: a directory holding
SKILL.md or a SKILL.md file (skill); a *.agent.md, or a .md directly under an agents/ directory
(agent); anything else stops without running a validator. Steps 1-3 live in
references/skill-flow.md and references/agent-flow.md, and gotchas that apply to one flow live in
that flow's file, since it is loaded on every invocation anyway. If validate.sh reports on the
other artifact type, the body restarts at Step 0.

Named factory-audit rather than forge-audit because forge is a live skill, and a family prefix that
matches a live sibling reads as ownership rather than membership.

The description carries one arrow per boundary target, because ADR-0020 resolves only the first
target after an arrow. It drops the quoted "audit this skill"-style phrases, which restated
"audited" in a second register (ADR-0020's duplicate-register rule). 241 characters, Gotchas 16%
of the body: no size SUGGESTIONs.

The boundary resolver stays embedded in two files rather than imported: a cache-installed plugin
cannot read outside its own directory, and the repo-root hook resolves via .pre-commit-hooks.yaml
where entry[0] is the only token pre-commit rewrites, so no single file is reachable by both.
tests/test-adr0020-contract.sh hashes both copies for byte-identity, and asserts validate.sh sources
the resolver and that no third copy exists.

The entry scripts classify the target from its resolved parent directory, so a bare agent filename
typed inside agents/ works; resolve SCRIPT_DIR CDPATH-safely; and exit 2 when a lib-*.sh is
missing, rather than dying with exit 1, the tier the flows relay as real findings.

The provenance run functions stash their findings code in KYBERFORGE_PROV_RC and
return 0, so validate-provenance.sh calls them UNTESTED. Testing a function's
status (`f || RC=$?`) disables errexit for its entire body, and no subshell or
`set -e` inside can re-arm it once the call sits in a condition context
(measured, both spellings). Their error paths use `exit`, which is unaffected
either way; this keeps errexit armed for anything added later.

Case 0's readability guard reads the file instead of asking `[[ -r ]]`. `-r` is
access(2), which answers yes for uid 0 even on a mode-000 file, and this repo's
dev environment is root -- so the guard could never fire where it exists to fire.
A read attempt is also the stricter question, catching EIO. This is the reasoning
scripts/check-vale-style-sync.sh carried before this commit deleted it; the
hazard did not go with it.

All three entry scripts are CDPATH-safe, vale-wrap.sh included: both of its cd sites are cleared,
the --config resolution and the directory-mirror walk, where an exported CDPATH would otherwise
print a decoy path into the -print0 stream and build the mirror from the decoy's files. The two
remaining bare cd calls take absolute paths, which CDPATH is never consulted for.

Impact

BREAKING: skill-audit and agent-audit no longer exist as invocable skills. kyberforge goes to
2.0.0 (catalog 0.4.7).

Check logic is unchanged: differential runs of the old and new validators across every skill and
agent produced byte-identical stdout, stderr and exit codes, and the reconstructed Python payloads
differ only in comments and the references/field-inventory.md -> agent-field-inventory.md rename.
One doctrine governs the tiers: exit 0 is audited and clean, exit 1 is audited with findings OR a
target present but unreadable, exit 2 is that nothing was audited at all. Edge paths DID change,
deliberately (full table in ADR-0025):
- a missing target exits 2 (never ran), not 1, under its own "does not exist" message; detection is
  by path shape, so a shape-matching path that is simply absent used to reach the validator and come
  back as a FAIL against a file that never existed;
- an unshaped target exits 2 under the generic "matches neither" message, and a directory with no
  SKILL.md under a third, distinct one -- three exit-2 messages, not one;
- a dangling symlink or a symlink loop stays exit 1: it is present but broken, which is a finding
  about the artifact rather than a usage error;
- a SKILL.md file path is audited as its skill directory instead of refused;
- a .md agent outside an agents/ directory is refused rather than audited;
- a missing script library, a missing python3, a missing PyYAML, and no argument at all each exit 2.
  validate-provenance.sh already exited 2 for the last two; validate.sh now matches it.

.pre-commit-hooks.yaml is a published contract consumed by external repos. Both hook IDs and both
files: regexes are unchanged; only entry: and description: moved.

scripts/check-vale-style-sync.sh (413), scripts/sync-vale-styles.sh (21),
tests/test-check-vale-style-sync.sh (797) and agent-audit/scripts/README.md (47) are deleted. The
checker made 17 assertions: 6 compared the two Vale copies and are moot; 10 are rehomed into
tests/test-vale-wrap.sh (case 0, cases 28-31, and the suite's Vale-absent skip); and the
cross-manifest files: agreement check, which selected hooks by entry: and so could not survive both
hooks sharing one, is ported as case 33 pairing hooks by id:. Cases 28, 30 and 33 carry mutation
self-tests; narrowing the local skill prefilter to 6 of 38 SKILL.md files now fails the suite.

Skills go 39 to 38. Pre-push goes 9 repo-authored hooks to 8.

ADR: 0025
BREAKING-CHANGE: the skill-audit and agent-audit skills are removed. Both flows are served by
  factory-audit, which auto-detects whether it was handed a skill directory or an agent file.

Plugin/APM scope — the single vendor-neutral file

One file, no counterpart: <package-root>/.apm/agents/<name>.agent.md. apm compile emits it to both the Claude Code and the Copilot CLI target. The .agent.md extension here is convention, not a Copilot marker — the file is vendor-neutral.

Frontmatter

The permitted keys are the apm-agent-allowlist section of factory-audit's references/agent-field-inventory.md. Read them from there as data — that section is the single source of truth, factory-audit's validate.sh parses it at load time, and it changes. Any restatement of the roster, here or in a template or in script output, goes stale one step further out than the list itself.

  • name — kebab-case, must equal the filename stem, unique within the scope.
  • description — write it against references/contract.md.
  • Everything else — check the allowlist section before adding a key. A key outside it fails the audit.

Why the list is narrow. apm compile copies frontmatter verbatim to every target with no per-target integrator, so a harness-specific value is wrong on at least one of them (ADR-0016). The rule is about a field's shape, not a fixed roster:

  • tools is an allowlist whose vocabulary differs per harness — Claude Code names its own tools, Copilot CLI uses aliases (execute/read/edit/search/agent/web) — so one value is wrong on one target. It stays out. Omitting it means inherit-all-tools on both, which is never wrong.

  • disallowedTools is a denylist, and denying by name cannot fail that way: a name the other harness does not recognise denies nothing, so the worst case is a missing fence, never a wrongly granted capability. That asymmetry is the whole exception (ADR-0016's 2026-08-14 amendment). Claude Code honours it for plugin subagents; the three fields plugin agents do silently ignore are hooks, mcpServers and permissionMode, and this is not one of them. Copilot's handling of the key is unconfirmed, which ADR-0016 accepts as a stated risk.

    Its syntax is the same at every scope, and this is the one scope that cannot reach it anywhere else: MCP tools are denied as mcp__<server>, mcp__<server>__* or mcp__*; both a YAML list and a delimited string are accepted, and this repo writes the comma-separated string form (disallowedTools: Edit, Write, NotebookEdit) — match it.

  • The Claude-only knobs (isolation, maxTurns, effort, memory, permissionMode, skills, color, initialPrompt, background, hooks, mcpServers) have no Copilot equivalent and are never written to this file at all. "Silently ignored at plugin scope" is the wrong framing: they are absent, not tolerated. To use any of them, copy the agent to .claude/agents/ (project scope) or ~/.claude/agents/ (user scope).

Write disallowedTools on every read-only plugin-scope agent — and say the agent is read-only in the body as well, because the fence does not cover the inherited Bash tool.

source_keys is provenance metadata, not a runtime field: both harnesses ignore it. Add it only when research sources informed the agent, with slugs matching H2 headings in the package root's sources.md.

Body

Follow the Body section of references/contract.md: role instruction, one job, and delegation to installed skills instead of transcribed procedure.

Before invoking factory-audit

  • name kebab-case, matching the filename stem, unique in scope
  • description written to references/contract.md
  • Every frontmatter key present in the apm-agent-allowlist section — in particular no tools
  • No FILL IN: placeholder and no <!-- ... --> template comment anywhere in the file
  • System prompt body non-empty, and a read-only agent says so in prose as well as in disallowedTools
  • Body covers all four required elements: inputs expected, process steps, output format, error handling — what the agent does on malformed, missing or contradictory input

Then return to the flow reference you came from.
