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.

skill-audit and agent-audit merge into one factory-audit with a Step 0 dispatch

Status: accepted (2026-09-15). Implements ADR-0020's "Merging siblings" rule, which named this exact pair, scoped itself to them, and then deferred the work as issue #101. The deferral is closed here. skill-author and agent-author stay separate — ADR-0020 excluded the author pair deliberately, and nothing in this change touches that exclusion.

Context

Every figure below was measured against the worktree on 2026-09-15. Re-derive rather than quote; the commands are given where a number is load-bearing.

The two skills duplicate content because they cannot share a file. plugins/kyberforge/.apm/skills/skill-author/references/deployment-modes.md, sourced from the agentskills.io spec, states the constraint for APM package mode: file references inside .apm/skills/<name>/ must not reach outside that skill's own directory, and the spec defines no cross-skill sharing mechanism. apm deploys skills flat into .claude/skills/<name>/ with no plugin tier above them, so there is no directory a second skill could read from. ADR-0024 re-confirmed this after deleting the native install path, specifically to stop the constraint being re-litigated as a Claude-Code artifact. It is not one. It binds under the only install path that survives.

What that constraint costs, between these two skills:

Duplicated artifact Lines Verification
ADR-0020 boundary resolver, embedded in both validate.sh copies 1,061 marker block 115..1175 (skill) and 189..1249 (agent); tests/test-adr0020-contract.sh assertion 1 hashes them
scripts/vale-wrap.sh 526 diff -q clean
assets/vale/styles/Kyberforge/, five rules 44 diff -r clean
Contributing-files parser, embedded in both validate-provenance.sh copies 93 marker block 300..392 (skill) and 294..386 (agent); diff -q clean on the extracted blocks
Removable by merging 1,724

On top of that, scripts/check-vale-style-sync.sh (413 lines) and tests/test-check-vale-style-sync.sh (797 lines) go with the merge. That is not because the whole gate was a copy diff; it was not, and saying so would overstate the case for deleting it. The script has 17 assertion sites: 13 err calls and 4 hard-fail exits. Its closing exit 1 only reports the err count, so it is not an assertion. Count them with git show 61b0b9c^:scripts/check-vale-style-sync.sh. An earlier revision of this ADR said 18. No reproducible counting rule gives 18, and it is corrected here.

Class Old line What it asserted Now
Moot (6) 19 REPO_ROOT is a directory nothing to guard; no script
42 the .apm/ paths are not stale no copies to locate
52, 56 neither copy is missing one copy
60 the two vale-wrap.sh copies are identical one copy
64 the two styles/Kyberforge/ copies are identical one copy
Rehomed (10) 95, 113 .vale.ini exists and is readable case 0
122 StylesPath = styles is set case 0
127 some section's BasedOnStyles names Kyberforge case 28 (Part B proves it fails)
174 no Kyberforge rule is overridden below a bare YES/error case 31
191 KyberforgeCopilot ships and is loaded case 30
308 vale is installed suite-level: exit 77, which run-tests --strict fails
341 every probe path matches some vale hook's files: regex case 28
347 every probe path raises a Kyberforge alert under the config cases 28 and 29
397 at least one probe row was checked case 28's section floor
Ported (1) 343 local and published files: regexes agree per probe case 33

Six are moot. Two diffed the copies, and four guarded the script's own ability to locate them: a real REPO_ROOT, non-stale .apm/ paths, and both copies present. With one copy and no script there is nothing left to diff or locate. The other ten read .vale.ini, the style directory and the hook manifests on their own terms, so they are rehomed rather than retired, into tests/test-vale-wrap.sh, which already owns the wrapper's behaviour against this config.

Two rehomed checks got stronger, because a text grep became a behavioural Vale probe:

  • line 127: case 28 Part B drops Kyberforge from a copy and requires vale to report the style as not loaded;
  • line 191: case 30 requires the Copilot rule to fire on .agent.md and nowhere else, and Part B proves both an unload and a leak fail.

The rest moved at equal strength. Case 31 is the same grep as before. An earlier revision claimed "7 of 11 stronger"; that claim is withdrawn.

The cross-manifest check is ported, not dropped. It extracts each vale hook's files: regex from .pre-commit-hooks.yaml (the external-facing manifest) and from .pre-commit-config.yaml (this repo's own copy of the same hooks) independently. It then asserts that a probe path in scope of one is in scope of the other. That catches this repo narrowing its local hook without narrowing the published one, or the reverse.

The original selected each hook's record by matching entry: against the owning skill's scripts/vale-wrap.sh path. After the merge both vale hooks point at the same entry, so that selector can no longer tell them apart. Case 33 pairs the hooks by id: instead, from an explicit table: kyberforge-vale-audit-skill ↔ vale-audit-prefilter-skill, and kyberforge-vale-audit-agent ↔ vale-audit-prefilter-agent. It carries the original six probe rows unchanged. It also fails by name on a missing hook id, and on a class with no shared probe.

An earlier revision of this ADR shipped without that port and called the gap half-closed by case 32. It was not. Narrowing vale-audit-prefilter-skill from ^plugins/[^/]+/... to ^plugins/kyberforge/... still matches tracked files of the right class. That clears case 32 while silently dropping every other plugin's skills from this repo's prefilter, and it was measured leaving the whole suite green. Case 33's Part B now makes exactly that mutation, the agent-hook equivalent and a renamed hook id, and requires each to fail.

Case 32 stays, for the separate zero-match question: each local hook must still select at least one tracked file, and only files of its own artifact class.

Line count. Merging removes the 1,724 duplicated lines above. Deleting the two sync-gate files (413 + 797 = 1,210) removes more, for 2,934 lines in total, plus one pre-push hook, check-vale-style-sync, formerly at .pre-commit-config.yaml:166. Two smaller deletions are not in that figure:

  • scripts/sync-vale-styles.sh (21 lines), the helper that regenerated skill-audit's copy from agent-audit's, now has nothing to sync.
  • agent-audit/scripts/README.md (47 lines) has no successor. Nothing referenced it, and the only README references/skill-file-structure.md mandates is tests/README.md, which survives.

The duplication is not symmetrical across the whole tree, and the asymmetry is what shapes the decision. Outside the shared resolver the two validate.sh copies total 1,293 lines (616 skill, 677 agent) and have 91 distinct lines in common. The two validators are not one script with a mode flag; they are two genuinely different scripts that happen to embed one identical block.

The bodies are the binding constraint on the merge. skill-audit's body is 724 words and agent-audit's is 808 — 1,532 together against BODY_MAX_WORDS = 900. Only 211 words are common to both (47 byte-identical body lines). A merged body that simply concatenated the two flows would fail the gate its own plugin enforces by a factor of 1.7, and there is no trimming route to 900: 1,321 of the 1,532 words are flow-specific.

Both skills already carry category: factory in their metadata, and both carry five source_keys — ten in total, disjoint, because they audit against different specs.

Decision

The two skills become one, named factory-audit.

1. The name. factory is what both already declare as their category, so the merged skill is named for the thing it audits rather than for the two input types it now dispatches between. Two alternatives were live and both are rejected below for naming reasons rather than substance: audit collides with the unrelated agentsmd-audit, and forge-audit makes a bare skill name a family prefix of a live sibling — forge exists at plugins/kyberforge/.apm/skills/forge/. No bare skill name may be a family prefix of another.

2. SKILL.md becomes a dispatch body. Steps 1-3 move out to references/skill-flow.md and references/agent-flow.md. The body carries the Gotchas that apply to both branches, the dispatch table, and Step 4 — Report, which is shared. This is ADR-0020's own rule ("Dispatch is mandatory at two or more mutually exclusive flows") applied to the file that defines it, and the word arithmetic above is why it is mandatory here rather than stylistic.

Dispatch happens at Step 0, keyed on the target path, before Step 1 runs. The table accepts exactly the shapes scripts/validate.sh detects:

  • A directory containing SKILL.md, or a SKILL.md file (its parent directory is audited), takes the skill flow.
  • A *.agent.md file, or a .md file whose immediate parent directory is agents/, takes the agent flow.
  • Anything else stops, runs no validator, and names the two accepted shapes.

Putting the dispatch after any deterministic check would mean running the wrong validator first and reading its output as a finding. An earlier revision of the body carried a two-row table with no fallback row. It could not route a SKILL.md file path, a trigger its own description advertised. Its agent row ("a path under .apm/agents/… or an agent markdown file") was both wider than the script and circular.

3. One entry point per script, auto-detecting, with the mode-specific half sourced.

  • scripts/validate.sh detects the target type itself, then sources scripts/lib-boundary-resolver.sh and one of scripts/lib-checks-skill.sh / scripts/lib-checks-agent.sh.
  • scripts/validate-provenance.sh does the same, sourcing scripts/lib-contributing-files.sh and one of scripts/lib-provenance-skill.sh / scripts/lib-provenance-agent.sh.

Two things justify this shape. First, self-containment binds between skills, not within one. The resolver had to be embedded verbatim in three copies because three skill directories cannot read each other's files; two files inside one skill directory have no such problem. Sourcing is available the moment the directory boundary between them disappears. Second, a single auto-detecting entry point makes a Step 0 misdispatch detectable. The script re-detects the flow from the target, so even after a misdispatch it runs the right checks and its finding tiers are correct. That alone does not make the misdispatch self-correcting, and an earlier revision of this ADR wrongly said it did. The flow file drives Steps 2-4, so a misdispatched audit would still apply the wrong Step 3 rubrics, print the wrong coverage line and recommend the wrong author skill. The body closes that gap with an explicit guard under the Step 0 table: if validate.sh reports on the other artifact type than the row taken, discard the run and restart at Step 0.

4. Reference files are prefixed by flow, with one exception. Every flow-specific file becomes skill-* or agent-* — skill-description-quality.md, agent-description-quality.md, skill-finding-criteria.md, agent-finding-criteria.md, and so on. The exception is sources.md, which stays singular and carries all ten source_keys, because the skill-side provenance check hard-codes os.path.join(skill_dir, "references", "sources.md") (pre-merge skill-audit/scripts/validate-provenance.sh:180, now scripts/lib-provenance-skill.sh:215). A per-flow sources file would mean changing the provenance contract to get a cosmetic gain.

5. Both exported Vale hook IDs survive unchanged. .pre-commit-hooks.yaml keeps kyberforge-vale-audit-skill and kyberforge-vale-audit-agent, keeps both files: regexes ((^|/)SKILL\.md$ and (^|/)agents/[^/]+\.md$|\.agent\.md$), and re-points both entry: lines at the one surviving vale-wrap.sh. Nothing in the published hook-repo contract changes: an external consumer's .pre-commit-config.yaml keeps working byte-for-byte across the merge. Two IDs pointing at one script is not a redundancy — it is what keeps the two files: scopes addressable independently, which is exactly ADR-0014's "one hook per file-scope" finding.

6. tests/test-adr0020-contract.sh changes in three ways, and the third is a conversion, not a deletion. Assertion 1 drops from three resolver copies to two: the merged factory-audit holds one, and scripts/skill-size-check.sh keeps its embedded copy. A new assertion 1a gives the resolver the same protection 1b already gave the parser. It asserts that validate.sh sources lib-boundary-resolver.sh in both mode branches, and that the resolver's BEGIN marker and def _authoring_root( appear in exactly those two files and nowhere else. A byte-identity hash alone would miss a third pasted copy, or an entry point that quietly stopped sourcing the library. Sourcing the resolver from the plugin tree into skill-size-check.sh was considered and refuted — that script is a repo-root hook consumed through .pre-commit-hooks.yaml, where entry[0] is the only token pre-commit rewrites, so it cannot reach a file inside the plugin at a path any consumer has. Assertion 1b is converted: it stops pinning that two validate-provenance.sh copies of the Contributing-files parser are byte-identical, and starts pinning that lib-contributing-files.sh is a single sourced copy that has not been re-inlined into either mode library. The claim it protects is the same one — the parser has exactly one authority — stated against the new structure. The drift history behind it is smaller than an earlier revision of this ADR implied. 484357a (2026-08-30) added the bullet-form parser to both copies with two different spellings of the loop: a temporary rest in skill-audit and an inline slice in agent-audit. The two were behaviourally identical. 598a7c3 (2026-09-01) unified the spellings and added the SHARED CONTRIBUTING-FILES PARSER markers that 1b hashed. From then until the merge's parent the two marker blocks were byte-identical (md5 0857272d… both). So the parser never parsed differently. What the gate never covered was the prose around the block, and a docstring there asserted identity the loop did not have. One sourced library removes the question.

7. Two things this change does not do. skill-author and agent-author are not merged here. That remains an open finding and it is unmeasured; ADR-0020 excluded the pair on the grounds that they emit genuinely different artifacts, and nothing measured in this session revisits that. And no audit criterion changes. Every check, tier, threshold, regex and branch is carried across as-is. The Python payloads reassembled from the new libraries differ from the pre-merge heredocs only in comments. The one exception is three lines naming references/agent-field-inventory.md, a byte-identical rename of field-inventory.md. Byte-level differential runs over every live skill directory and agent file matched stdout, stderr and exit code.

The entry points are not behaviour-neutral, and an earlier revision of this ADR said they were. Those differential runs used valid targets only, so they could not see that the new detection layer changed what happens to invalid ones. Every change below is deliberate:

Input Pre-merge Now
a missing path, a directory with no SKILL.md, a non-agent .md (e.g. README.md) exit 1, or a mode-specific exit-2 message exit 2 with one generic "matches neither" Error/Why/Fix. Exit 2 is the never-ran tier, so the flow files report the section as unverified and quote the reason.
a SKILL.md file path exit 1 or 2 (…/SKILL.md/SKILL.md not found, "not a directory") accepted; its parent directory is audited
an agent .md not under an agents/ directory (e.g. ~/drafts/my-agent.md) audited refused, exit 2. Detection never guesses. No tracked file in this repo is affected.
a bare or ./-relative agent filename, run from inside its agents/ directory audited audited. The parent directory's name is read from the real path, not the typed string.
a lib-*.sh missing or unreadable, or the script directory unresolvable did not apply (single file) exit 2 with Error/Why/Fix, never a raw bash error at exit 1, which is the real-findings tier
CDPATH exported did not apply (no cd) no effect. SCRIPT_DIR resolves with CDPATH='' and cd -- … >/dev/null.
no argument Error: skill-dir is required. / agent-file is required. one combined message and usage block; exit code unchanged (1 from validate.sh, 2 from validate-provenance.sh)

A single validate.sh copied or symlinked out of its scripts/ directory still does not work, because its libraries are not beside it. It now fails at exit 2 and says so.

Considered options

Keep two skills and rely on the byte-identity contract test alone (rejected). This is the status quo: tests/test-adr0020-contract.sh already hashes the resolver across copies, and check-vale-style-sync.sh already diffs the Vale halves at pre-push. Only 6 of its 17 assertion sites exist because there are two copies. The other 11 do other work, and are rehomed or ported above rather than being an argument for the status quo. On the duplication itself it polices drift rather than removing the thing that drifts, and it pays 2,934 lines plus a pre-push hook to do so. It also leaves the router carrying a mutually-excluding near-miss pair whose two descriptions each spend a boundary clause pointing at the other — a routing cost the merge removes for free. ADR-0020 already weighed this option for this pair and chose merging; nothing measured since changes the balance.

One monolithic dispatching validate.sh (rejected). Dropping one resolver copy from the concatenation of the two current files gives roughly 2,354 lines in a single script. It is the straightforward reading of "merge the scripts", and it is wrong on the evidence: the two validators share only 91 distinct lines outside the resolver, so a monolith would be two near-disjoint implementations behind one if, with every future edit to either half requiring a reader to hold both in context. Sourcing per-mode libraries gets the same single entry point and keeps the halves readable apart.

Genuinely merging the three colliding reference files into two-section files (rejected). description-quality.md, finding-criteria.md and validation-scripts.md exist under both skills today, and folding each into one file with a skill section and an agent section is the tidier-looking outcome. It defeats the dispatch. The entire point of moving Steps 1-3 into references/ is that an invocation loads one flow's content and not the other's; a two-section reference file re-inflates per-invocation context to the full 1,532-word span the body ceiling forced out. ADR-0020 measured these same files at 100 of ~120 differing lines after normalising skill/agent, so the merged file would also be mostly disjoint text under one heading.

Naming it audit (rejected). Shortest available name and an accurate one. It collides with agentsmd-audit, which audits a repo's AGENTS.md and has nothing to do with the factory. A bare audit alongside it reads as the general case of a skill it is unrelated to, which is precisely the routing confusion a merge is supposed to reduce.

Naming it forge-audit (rejected). It matches the plugin and reads well. forge is a live skill in the same plugin, so forge-audit makes one bare skill name a prefix of another — a router asked to distinguish forge from forge-audit is being asked to disambiguate on a suffix, and a user typing forge gets an ambiguity that does not exist today.

Collapsing the two exported Vale hook IDs into one (rejected). With a single vale-wrap.sh and a single .vale.ini, one hook ID looks sufficient. It is a breaking change to a published hook-repo contract: any external repo pinning kyberforge-vale-audit-agent breaks on upgrade, for no gain. It also re-creates ADR-0014's measured failure in a new place — that ADR confirmed empirically that a single hook entry pointed at one config silently scanned 0 files of the other type. Two IDs cost two manifest stanzas and keep both file scopes explicit.

Consequences

The single-file .vale.ini comes back, and this does not reverse ADR-0014. ADR-0014 split one root config into two skill-scoped copies because two skills each needed their own, and no plugin-level shared directory exists to hold one. Its reasoning is untouched; the merge removes the condition that reasoning operated on. One skill needs one config, so the union is written back into one file. The union is behaviour-neutral and this was checked rather than assumed: skill-audit's config has a single [**/SKILL.md] section, agent-audit's has [**/agents/*.md] and [**/*.agent.md], and no file in the corpus matches more than one of the three. Where an overlap is constructible at all (agents/SKILL.md), both matching sections assign BasedOnStyles = Kyberforge, so even then no verdict moves. KyberforgeCopilot stays scoped to [**/*.agent.md] exactly as it is now, which is what keeps the merged config from widening Copilot-specific rules onto SKILL.md.

scripts/check-scope-walkup-sync.sh survives, and confusing it with check-vale-style-sync.sh is the obvious mistake here. The two look like the same kind of gate and are not. The walk-up checker covers four independent ports of the scope walk-up, and only two of them live in the audit pair: the other two are agent-author/scripts/new-agent.sh and skill-author/scripts/new-skill.sh, which this change does not touch. They are also Bash where the audit pair's are Python, so as its own header records, it can never become a text diff — it asserts behavioural agreement across a fixture matrix instead. Merging two of four ports leaves three ports and the same job.

Roughly 71 files carry inbound references to the two skill names and must be re-pointed. Derived as git grep -l -E "skill-audit|agent-audit" | wc -l — it includes ADRs, LESSONS.md, docs/spec/gates.md, both author skills' routing targets, forge's dispatch, the test suite and the two manifests. Boundary clauses naming skill-audit or agent-audit are the sharp end: ADR-0020's resolvable-target check is a blocking ERROR on a dangling route, so a missed rename fails the push rather than degrading quietly. Historical references inside ADRs describing the pre-merge state stay as they are; the resolver reads boundary clauses in descriptions, not ADR prose.

The dispatch body carries only the gotchas common to both flows, and ships with no SUGGESTION. An earlier revision of this change shipped the Gotchas section at 229 of 548 body words, 42%, against GOTCHA_MAX_BODY_FRACTION = 0.25. It accepted that as standing output, arguing that moving a gotcha to references/ meant an extra file read on every invocation. That argument was wrong for the two gotchas that were over budget, because neither was shared:

  • the Agent flow, plugin/APM scope only provider-safety bullet names its one branch in its own text;
  • the 112-word body-word-gate bullet was two separate pre-merge gotchas welded together, a skill half and an agent half.

A dispatch body is the dispatch table plus the gates common to every branch (CONTEXT.md; the skill-flow rubric references/skill-body-discipline.md). Keeping a single-branch gotcha in it contradicts that definition. Moving it into its flow file costs no read either, because the body already loads exactly one flow file on every invocation by construction.

So the skill half now sits under ## Gotchas in references/skill-flow.md. The agent half and the provider-safety bullet sit under ## Gotchas in references/agent-flow.md. The body keeps three gotchas: the no-narration rule, the disable-model-invocation exemption and the Vale 0 files trap. Measured with scripts/skill-size-check.sh thresholds zeroed to force the figures out, the section is now 91 of 555 body words, 16%.

Every invocation now reads one extra references/ file. The dispatch body names the flow file and the agent loads it, where today Steps 1-3 arrive with the body. This is the cost the progressive- disclosure trade always carries, and it is paid against a saving: an invocation loads the dispatch body plus one flow instead of a body that would have to carry both. It is also the reason the two-section reference file was rejected above.

The original audit's figures for this finding were wrong in three ways, and each is worth naming so the correction is not re-derived from scratch later.

  • It claimed roughly 3,300 duplicated lines and two pre-push hooks. The measured removal is 2,934 lines and one hook. The second hook it counted was check-scope-walkup-sync, which survives for the reason above.

  • It claimed the two validators were one script hard-wired per mode. They are not. Outside the shared resolver they total 1,293 lines with 91 distinct lines in common. That error matters because it is what made the monolithic validate.sh look like the obvious implementation.

  • It named the merged description as the blocker on merging. It is not. Merging deletes description content rather than accumulating it: the Not a skill directory -> skill-audit clause loses its referent, and the "is this ready to ship" trigger was duplicated verbatim across both. The two descriptions it replaces measure 239 (skill-audit) and 250 (agent-audit) at 61b0b9c^. The description this skill ships measures 241, inside the 250 SUGGESTION target. It carries one arrow per boundary target (Not applying skill fixes -> skill-author. Not applying agent fixes -> agent-author.), because ADR-0020 resolves only the first target after an arrow, so a one-arrow form would leave agent-author checked by nothing. The real blocker was the body: 1,532 words against BODY_MAX_WORDS = 900, with only 211 words shared. Diagnosing the description would have produced a merge with a concatenated body that failed its own plugin's gate.

    Correction to an earlier revision of this bullet. It shipped the description at 319 characters and accepted the SUGGESTION. It said the excess paid for the second arrow and for "both flows' artifact-specific trigger phrases carried in full". Only the arrow was worth it. The trigger phrases stated one trigger twice in two registers: "a skill directory or agent definition audited", then quoted audit this skill, review my SKILL.md, audit this agent and review my agent file. ADR-0020 makes that a FAIL ("Stating the same trigger twice in two registers is a FAIL"), so it was not a cost of merging. Dropping the quoted duplicates, and keeping the one indirect trigger that omits the domain word (is this ready to ship), gives 241 with both arrows kept. The same revision's "240 characters" figure for a hypothetical single-arrow merge was never reproduced, and is withdrawn rather than re-derived.

factory-audit shipped at metadata.version: "1.0.0", not ADR-0022's 0.1.0 for a new skill. It is a new directory, but not a new skill in the sense ADR-0022's starting version encodes: it carries every check, rubric and reference of two skills that were both already at 1.0.0, and resetting to 0.1.0 would signal an immaturity that the merged content does not have. The fixes above to Step 0, the gotchas and the description are an improve pass, so under skill-author's patch-bump rule it is now 1.0.1. The plugin itself goes from 1.6.2 to 2.0.0, because removing two invocable skills breaks anyone calling them by name.
