fix: ignore hidden agent skills during review

[Ugesh-Praavin]

Summary

Fixes #294.

• Exclude hidden path segments and node_modules from default skills/ discovery during maintainer review
• Share the default skill-path predicate with maintainer setup to keep discovery behavior aligned
• Preserve explicitly declared skills, custom roots, and existing review state
• Add regression coverage for .claude/, .cursor/, and .agents/ skills

Testing

• pnpm vitest packages/intent/tests/review.test.ts --run: 46 passed, 1 pre-existing unrelated failure
• pnpm vitest packages/intent/tests/maintainer.test.ts --run: 31 passed, 3 existing unrelated failures
• pnpm exec prettier --check packages/intent/src/review/review.ts packages/intent/src/shared/utils.ts packages/intent/tests/review.test.ts packages/intent/src/maintainer/existing.ts: passed
• git diff --check: no whitespace errors (Windows CRLF warnings only)

The new regression test for hidden agent directories passes.

Summary by CodeRabbit

• Bug Fixes
  • Default skill discovery now excludes SKILL.md files located in hidden directories or node_modules. Skills in standard locations continue to be discovered, while custom roots, explicitly declared skills, and previously recorded skills remain eligible under their existing rules. This helps keep the set of skills found during review consistent with the configured discovery paths.

📝 Walkthrough

Walkthrough

Maintainer setup and review discovery now use a shared path predicate to filter default skill files. A test covers hidden agent directories and a regular skill path. A Changeset declares a patch release for @tanstack/intent.

Shared default skill path filtering packages/intent/src/shared/utils.ts, packages/intent/src/maintainer/existing.ts, packages/intent/src/review/review.ts, packages/intent/tests/review.test.ts, .changeset/icy-loops-act.md	The shared isDefaultSkillPath predicate excludes paths with hidden components or a node_modules component. Maintainer setup and default review discovery use the predicate. Existing custom-root, declared-skill, and previously recorded-skill conditions remain unchanged. The test checks hidden agent directories and a regular skill path. The Changeset declares a patch release.

Review details

Systems and components

• observed — packages/intent (library) was modified; 4 changed files map to changed impact.

Before / after behavior

• observed — Modified behavior in packages/intent/src/maintainer/existing.ts: Imports isDefaultSkillPath alongside parseFrontmatter for use in skill-file filtering.
• observed — Modified behavior in packages/intent/src/maintainer/existing.ts: Replaces the exclusion of paths containing hidden components or node_modules with the isDefaultSkillPath predicate; files failing that predicate are no longer included.
• observed — Modified behavior in packages/intent/src/review/review.ts: The utility import adds isDefaultSkillPath for skill-path classification.
• observed — Modified behavior in packages/intent/src/review/review.ts: Skill files under skills/ now qualify only when isDefaultSkillPath(path) is true; previously, any SKILL.md under a skills/ directory qualified. The existing custom-root, declared-skill, and previously recorded-skill alternatives remain unchanged.
