Three ways the gates could report green having measured nothing. All three were
invisible to a passing test suite, because pre-commit prints nothing at all for a
hook that exits 0 — a gate that declines to check and a gate that checked and
passed produce the identical signal.
- A UTF-8 BOM, a leading blank line, a trailing space after a `---` marker or
CRLF line endings defeated the `^---\n` frontmatter matcher. Every ADR-0020
check was then skipped and the file passed: measured at the time, a
550-character description with a 1,000-word body exited 0 behind a BOM.
All four shapes are now tolerated, and frontmatter that genuinely cannot be
parsed is a hard ERROR rather than a silent skip.
- An agent file with a valueless `description:` followed by another key let a
line regex capture the *next* key, which looked non-empty, so the
missing-or-empty branch never fired and every gate below it early-returned on
the empty folded value — zero output, exit 0, on a blocking gate. The one
field this contract is entirely about was the one field a gate could fail to
notice was absent. Presence is now decided on the YAML-folded value and
nowhere else, and a missing or empty description is a hard FAIL in all three
validators.
- The hand-rolled frontmatter fallback disagreed with PyYAML across the FAIL
boundary on folded scalars, so which reader happened to be available decided
the verdict. A fallback that mis-parses a scalar shape reports a vacuous pass,
which is worse than not running, so it is deleted: python3 and PyYAML are hard
requirements that fail loudly with an install pointer.
Boundary-target resolution no longer derives its universe from its own location.
A `${BASH_SOURCE}`-relative repo root leaked this repo's 39-skill universe into
every consumer repo running the hook through pre-commit, so a consumer skill
routing to `skill-audit` resolved against a plugin it had never installed. The
interim form resolved through `.claude/` and `.agents/`, which are gitignored
`apm install` output — the same commit reported 2 dangling targets on a machine
that had run the install and 6 on a fresh clone. Resolution now walks up from the
file being checked to an authoring root (nearest ancestor holding
`plugins/*/.apm/{skills,agents}`, else the nearest `.git`, in two passes so a
nested `.git` cannot outrank a real monorepo root); the universe is every skill
and agent under `<root>/plugins/*/` plus the file's own apm package and that
package's declared `dependencies.apm`. Deployed trees are consulted only when no
authoring root exists at all — the consumer case. One commit now gets one verdict,
which a gate shipping hot with no baseline file has to.
Narrowed in the same pass: a routing target inferred from the prose boundary form
and corroborated by nothing else reports at SUGGESTION instead of blocking. A
blocking check with no escape hatch is the wrong trade when the inference from
prose is the weak part of it.
New deterministic checks, all previously untested or absent: every
`references/<file>.md` a body names must exist (ERROR — a broken pointer is not a
style opinion); a description with no boundary clause at all, a Gotchas section
over five entries, and a Gotchas section over 25% of the body are SUGGESTIONs.
Where no universe can be determined the target check prints `INFO ... DID NOT
RUN` rather than passing quietly. Each prose-scanning check needed its own
false-positive fix — a fenced example of a Gotchas section was being read as the
section itself — and those fixes are pinned rather than assumed.
The resolver is one block copied verbatim into all three scripts between
BEGIN/END markers, because a cache-installed plugin's scripts cannot read outside
their own plugin directory. Nothing asserted the copies were still identical; a
one-line edit to a single copy passed every constant-agreement assertion, since
constants are not what drifts.
Tests land here rather than in a later commit. The existing suites assert the old
behaviour and go red against these scripts, so splitting them would leave a commit
whose own `run-tests` pre-push gate fails in isolation.

# Two independent gate families live in this script. Do not conflate them.
|
||
#
|
||
# 1. SPEC CONFORMANCE (MAX_LINES / MAX_WORDS, unchanged). Enforces
|
||
# agentskills.io's skill-authoring.md guidance: keep SKILL.md within 500
|
||
# lines and roughly 5,000 tokens, so the full body doesn't crowd out
|
||
# conversation history and other active skills once loaded into context.
|
||
# MAX_WORDS counts the WHOLE FILE, frontmatter included.
|
||
#
|
||
# 2. CONTEXT BUDGET (ADR-0020: description chars, body-only words, resolvable
|
||
# boundary targets). A skill's name + description is preloaded into every
|
||
# agent's context every session whether or not the skill is ever invoked;
|
||
# the body is loaded only on invocation, and then competes with the caller's
|
||
# live conversation. Those are different costs with different ceilings, so
|
||
# they get their own numbers and their own measurements.
|
||
#
|
||
# The two families measure different things on purpose and neither replaces the
|
||
# other: 2,770 whole-file words is a conformance backstop, 900 body-only words
|
||
# is a quality gate, and a file can sit well inside one while failing the other.
|
||
#
|
||
# Vale can't express any of this (its checks operate on text patterns, not raw
|
||
# file size), so this is a plain script instead of a Vale rule.
|
||
#
|
||
# Both spec ceilings are inclusive: a file at exactly MAX_LINES or MAX_WORDS
|
||
# passes, and only one past it fails. That matches
|
||
# skill-audit/scripts/validate.sh, which has always used `line_count <= 500` as
|
||
# its pass condition — the two previously disagreed at exactly 500 lines, so a
|
||
# SKILL.md could pass its own audit and still be blocked by the commit hook.
|
||
# The ADR-0020 ceilings are inclusive the same way.
|
||
#
|
||
# Token counts aren't computed exactly here — word count (`wc -w`) is used as
|
||
# a proxy. Measured over this repo's 39 in-scope SKILL.md files, characters per
|
||
# word runs min 5.97 / median 6.79 / mean 6.77 / max 7.22. At the standard
|
||
# ~4-characters-per-token English approximation that is 1.49 / 1.70 / 1.69 /
|
||
# 1.81 tokens per word.
|
||
#
|
||
# MAX_WORDS=2770 is therefore calibrated to the corpus WORST case rather than
|
||
# its median: 2770 words at the densest observed 7.22 chars/word is ~20,000
|
||
# characters, or ~5,000 tokens at the 4-characters-per-token approximation. So
|
||
# what this gate guarantees is "under 5,000 tokens even for the densest prose
|
||
# the corpus has produced" — the earlier median-calibrated MAX_WORDS=2900 let
|
||
# such a file sit at exactly the ceiling and still spend ~5,240 tokens. A
|
||
# median-density file at 2770 words spends ~4,700 tokens, so typical prose
|
||
# gives up ~130 words of headroom to close that gap. The largest SKILL.md in
|
||
# the repo is 2,760 words whole-file (skill-author), twelve words under the
|
||
# ceiling — this is a gate two files have already grown into, not headroom.
|
||
#
|
||
# It is a one-sided proxy in the useful direction — nothing under the word
|
||
# ceiling is wildly over the token ceiling — but it is not exact BPE
|
||
# tokenization and does not replace one. Re-measure the corpus before treating
|
||
# any of these numbers as still current.
|
||
#
|
||
# python3 AND PyYAML are required for the ADR-0020 half, and both are hard
|
||
# dependencies rather than best-effort: python3 because pre-commit (which is how
|
||
# this script runs) is itself a Python application, and PyYAML because the
|
||
# hand-rolled folding reader that used to cover its absence disagreed with a
|
||
# real parser across the FAIL boundary. Two readers that measure the same
|
||
# description differently is worse than one reader that refuses to start.
|
||
|
||
# These constants are intentionally duplicated in
|
||
# skill-audit/scripts/validate.sh (Python) rather than shared from one file:
|
||
# this script is a standalone bash pre-commit hook, that one is an in-skill
|
||
# Python validator invoked in a different context (same rationale as
|
||
# vale-wrap.sh's per-plugin duplication — see its own header comment).
|
||
# tests/test-skill-size-check.sh asserts both files agree on these values, so
|
||
# drift between them fails CI rather than silently diverging.
|

#
|
||
# The ADR-0020 constants below are duplicated the same way and carry the same

# warning: skill-audit/scripts/validate.sh holds a second copy of

# --- Extraction -----------------------------------------------------------
|
||
# False positives are the design constraint here, not recall. The rules:
|
||
# * A BARE target must be hyphenated AND sit in a boundary sentence (one
|
||
# carrying "do not"/"instead"/"rather than"/"not for"). Without the second
|
||
# condition, pc-run's "run pre-commit hooks" reads as a route to a
|
||
# non-existent `pre-commit` skill.
|
||
# * A BARE arrow target counts only in ADR-0020's compressed boundary form,
|
||
# `Not <thing> -> <skill-name>`. Without that, diagnose's process chain
|
||
# "fix -> regression-test" reads as a route to `regression-test`.
|
||
# * A backticked hyphenated token counts only inside a boundary sentence.
|
||
# Unconditionally, `pre-push` or `commit-msg` in a TRIGGER clause is a hard
|
||
# FAIL with no escape hatch. Gating it costs nothing (measured over this
|
||
# corpus: 54 targets before and after); DELETING it costs 7 real targets
|
||
# across three gitea skills, so it is gated, not removed.
|
||
# * SINGLE-WORD targets are deliberately NOT matchable bare — `research`,
|
||
# `triage`, `forge`, `prototype` and `tdd` are all real skill names and all
|
||
# ordinary English, so a bare-word rule would flag most of the corpus. A
|
||
# single-word target must be written `` `forge` `` or /forge to be seen.
|
||
# That is a known recall limitation, accepted over the false positives.
|
||
# Tool names (Read/Write/Edit) are excluded by the lowercase-only pattern; MCP
|
||
# tool names (issue_write) by its rejection of underscores; file names by its
|
||
# rejection of dots and slashes.
|
||
#
|
||
# ATTRIBUTIVE USE. The boundary-sentence gate above does NOT solve the
|
||
# `pre-commit` false positive, and the comment that claimed it did was wrong:
|
||
# "instead", "rather than", "do not" and "not for" are exactly the words a
|
||
# boundary clause uses, so the gate is open precisely where the risk is. All of
|
||
# these were hard dangling FAILs with no suppression:
|
||
# Use pre-commit hooks instead of ad-hoc scripts.
|
||
# Invoke the pull-request template instead of writing one by hand.
|
||
# Use conventional-commits formatting rather than free-form messages.
|
||
# Composes label-resolution logic instead of duplicating it.
|
||
# Do not use for X — run the `pre-push` hooks instead.
|
||
# What separates every one of them from a real route is grammar, not marking:
|
||
# the hyphenated token is a compound MODIFIER of the noun that follows it
|
||
# ("pre-commit hooks", "pull-request template"), where a route target is
|
||
# terminal — followed by punctuation, a conjunction, or a boundary word. So a
|
||
# target whose next token is an ordinary lowercase noun is CONFIRM-ONLY: it
|
||
# still resolves and still counts as a route when the name exists, but it can
|
||
# never raise a dangling error on its own.
|
||
#
|
||
# This is deliberately NOT the simpler "only marked targets may dangle" rule,
|
||
# which would have been wrong here: BOTH live true positives in this corpus are
|
||
# BARE — research's "(use neuledge-context)" and gitea-issues' "Composes
|
||
# gitea-labels-\n milestones", where the `>` fold yields "gitea-labels-
|
||
# milestones" and the trailing hyphen is what keeps it terminal. Marking is a
|
||
# poor proxy, so the follower token is the signal, and it is applied to
|
||
# backticked targets too.
|
||
#
|
||
# TERMINAL IS NOT ENOUGH — IN-SENTENCE CORROBORATION. The follower test clears
|
||
# `pre-push` in the example above only because that example happens to be
|
||
# followed by the noun "hooks". Move the same token into terminal position and
|
||
# it was a hard FAIL again, with no suppression mechanism anywhere in this gate:
|
||
# Do not use for running hooks — run `pre-commit` instead.
|
||
# Do not use for the commit message — see `commit-msg`.
|
||
# Do not use for type errors — run `type-check` first.
|
||
# Instead, use `semantic-release`.
|
||
# Do not use for the old flow — use the clean-up instead.
|
||
# Do not run end-to-end, run unit-tests.
|
||
# Every one of those is grammatically identical to a genuinely broken route:
|
||
# "route verb + hyphenated name + terminal" is also exactly how prose cites a
|
||
# tool, a hook, a file format or an English compound. Nothing local separates
|
||
# them, and the skills most exposed are the ones this contract sends authors
|
||
# back to rewrite first — pc-run, pc-author, vale-run, vale-config and the apm-*
|
||
# family are all ABOUT hyphenated tools.
|
||
#
|
||
# So the confidence to BLOCK a commit comes from the sentence, not the token: a
|
||
# prose-form target may raise a hard error only when its own sentence names at
|
||
# least one OTHER target that RESOLVES. A routing sentence proves itself by
|
||
# routing somewhere real; a lone unresolvable name proves nothing. That is not a
|
||
# rule fitted to the fixtures — it is the shape of both live true positives,
|
||
# which sit beside `write-docs` and `gitea-labels-milestones` respectively, and
|
||
# it changes this corpus's verdict by exactly nothing.
|
||
#
|
||
# An uncorroborated unresolvable target is NOT discarded: every caller reports
|
||
# it at its SUGGESTION tier, naming the target. The finding stays visible on
|
||
# every run; only the power to block a commit is withdrawn, which is the part
|
||
# that had no escape hatch.
|
||
#
|
||
# EXPLICIT ROUTE NOTATION is exempt from corroboration and always blocks:
|
||
# ADR-0020's compressed arrow (`Not <thing> -> <name>`) and Claude Code's
|
||
# invocation form (`/<name>`). Neither is ever how English cites a tool — nobody
|
||
# writes `-> pre-commit` or `/pre-commit` to mean the hook — so there is no
|
||
# ambiguity to resolve, and an author who wants a route checked unconditionally
|
||
# has two ways to say so.
|
||
#
|
||
# NAMESPACE: `plugin:skill` is live in this repo (native user-scope installs
|
||
# still resolve `gitea:gitea-prs`), so the patterns admit an optional
|
||
# `<plugin>:` prefix and normalize_target() strips it before resolution.
