The ADR-0020 boundary resolver (boundary_targets()/unresolved_targets())
only ever read a SKILL.md's description. A target named in the BODY -- a
dispatch table row, a "run X" step, both routine in a 900-word procedure
-- was checked by nothing. Two real instances shipped before either was
caught by reading rather than by a gate: bin/write-docs routed twice to a
deleted `to-prd` skill, and bin/triage told an agent to run a nonexistent
`/setup-matt-pocock-skills` (both fixed in 03abcff; that fix was the
symptom, this gate is the actual ask per #124).
Added a separate, narrower extractor -- body_targets() /
unresolved_body_targets() in the shared lib-boundary-resolver.sh -- rather
than reusing the description resolver at wider scope. The description
gate's sentence-level heuristics (BOUNDARY_MARKER, the follower test,
in-sentence corroboration) are tuned for a one-to-three-sentence routing
clause and misfire on dispatch-table/procedure prose in both directions,
so the body gate reads only explicit route notation (`/name`,
backticked-or-slash-prefixed `-> name` / `-> name`), already the
description gate's own unconditionally-blocking tier.
Three guards were added after running the extractor over the real
39-skill corpus and reading every hit rather than assuming the design was
correct:
- a target must be hyphenated, even in notation -- single-word citations
like `/fork` (forge, citing Claude Code's own /fork command) and
`/name` (skill-author, a placeholder) are not routes.
- a bare hyphenated word after any arrow is not notation -- only
ARROW_MARKED (backticked/slash-prefixed) is used, not NOTATION_ARROW's
bare form, so ordinary process-chain prose ("prop -> new ref ->
re-render", caveman) is not read as a route.
- a name immediately preceded by `<` is a closing tag
(`</what-to-do>`, grill-with-docs), not /name notation.
Wired into both consumers that must agree by contract: scripts/
skill-size-check.sh (the pre-commit hook) and factory-audit's
lib-checks-skill.sh (the audit). Verified identical findings across both
over the whole corpus.
tests/test-adr0020-targets.sh gains a dedicated section pinning the two
live true positives and all three guards. docs/spec/gates.md and
ADR-0020 get a matching amendment.

Skills no longer carry a README.md, so the size advice in
skill-size-check and factory-audit's validator now names a references/
file instead.
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Why: scripts/skill-size-check.sh embedded a byte-identical 1,061-line copy
of the ADR-0020 boundary resolver only because it was also exported
through .pre-commit-hooks.yaml, whose consumers could not reach a file
inside the plugin. 4de5b6b retired that export, so the hook now runs only
in this repo and can source factory-audit's lib-boundary-resolver.sh like
validate.sh does. One copy removes the edit-one-paste-the-other hazard.
Implementation Notes:
- The hook's Python program is assembled from its own preamble, the
library's resolver and its own checks, read from quoted here-docs. The
assembled program matches the old one line for line except one comment,
and the hook's stdout, stderr and exit code are identical over every
corpus SKILL.md and the 26 differential-suite fixtures.
- The hook fails closed, naming the library, when it is missing or
defines no resolver.
- test-adr0020-contract.sh assertion 1 now pins the single copy: one
marker pair in the library, none in the hook, fail-closed on a missing
or gutted library, and a sentinel planted in a copied library that must
appear in the hook's output. 1a expects exactly one authority. 27 -> 29
passes.
- ADR-0020 and ADR-0025 carry dated amendments; gates.md and the
library, hook and mode-library comments no longer describe two copies.
- factory-audit is new on this branch, so the version-bump gate exempts
it; kyberforge is already at 2.0.0 against main's 1.6.2.

Why: two branches that both bump a skill 1.0.0 -> 1.0.1 with different
content merge without a conflict, and each passed the gate against its own
merge-base, so main could ship two changes under one version.
Implementation Notes:
- check-skill-version-bump requires the pushed version to exceed both the
merge-base and the main tip; failures name the baseline they missed.
- Presence is read from the tree, so a blob missing from a partial clone is
a read failure instead of a silently exempt "new" skill.
- A leading UTF-8 BOM no longer reads as a missing version.
- Version parts reject leading zeros in all three validators
(check-skill-version-bump, skill-size-check, factory-audit).
- New tests cover equal bumps, moved files, major/minor ordering, bad refs,
unreadable blobs, mode-only changes, symlinks and tag peeling.
Impact: ADR-0022 amended (reverses "not main's current tip"); gates.md
updated to match, including pre-commit 4.6.1's exact ref selection.
ADR: 0022

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.
