maintainer review treats SKILL.md files in hidden agent directories as library skills

[viclafouch]

Problem

intent maintainer review treats every SKILL.md under a skills/ directory as a library skill, including skills in hidden agent directories such as .claude/skills/. These are repository-local agent skills: they are not published and declare no sources. Review reports each one as pending, and recording fails, so maintainer check cannot pass in a repository that has project-level agent skills.

maintainer setup already excludes these paths when it registers existing skills, so the two commands disagree on what a library skill is.

Reproduction

In a pnpm workspace with one package skill and one project-level Claude Code skill:

.claude/skills/add-a-package/SKILL.md      # repository-local agent skill, no sources
packages/client/skills/client-core/SKILL.md
_artifacts/{domain_map.yaml,skill_spec.md,skill_tree.yaml}

pnpm exec intent maintainer setup
pnpm exec intent maintainer review --updated "Initial review."
pnpm exec intent maintainer check

maintainer setup registers only packages/client/skills/client-core/SKILL.md, as expected.

maintainer review --updated fails:

Review skill:.claude/skills/add-a-package/SKILL.md has unresolved source evidence. Fix the source mapping before recording it.

maintainer check reports:

Review skill .claude/skills/add-a-package/SKILL.md: No source paths declared. Add the evidence used to author this skill.

Adding .claude/** to review.ignore in skill_tree.yaml does not help: that list filters unmapped changes, not skill discovery.

Cause

Review selects skill files with a path test only (review.ts#L565-L572):

basename(path) === 'SKILL.md' &&
  (/(^|\/)skills\//.test(path) || /* ... */)

Setup applies the same test and also skips hidden segments and node_modules (existing.ts#L74-L83):

basename(path) === 'SKILL.md' &&
  /(^|\/)skills\//.test(path) &&
  !path
    .split('/')
    .some((part) => part.startsWith('.') || part === 'node_modules')

Expected

Review discovers the same default set as setup: hidden agent directories (.claude/, .cursor/, .agents/, …) stay out unless the skill tree declares the path explicitly, or review state already records it.

Suggested fix

Apply the hidden-segment filter of existing.ts to the /(^|\/)skills\// branch in review.ts, and keep the customRoots, declaredSkills and review-state branches as they are. A shared helper would keep the two rules from drifting again.
