# Pattern Library Manager ## Purpose Add, tighten, or document reusable approved patterns and anti-patterns in this bundle without leaking host-project facts into publishable rules. This skill owns small reusable pattern-library changes: descriptions, bad/good examples, graph links, trigger/output evals, and validation alignment. ## When To Use Use this skill when the user asks to: - add a reusable approved pattern; - add a reusable anti-pattern; - tighten an existing common pattern or anti-pattern; - add code examples to a pattern or anti-pattern; - add pattern examples sourced from official documentation or user-provided snippets; - add eval coverage for a pattern-routing regression; - update `common/approved-patterns.md`, `common/anti-patterns.md`, or `common/anti-patterns/**` for reusable behavior. ## When Not To Use Do not use this skill for: - project-specific patterns or anti-patterns; use local-only `project/**` overlays instead; - general skill creation unrelated to patterns; use `agent-rules-skill-author`; - implementation, bugfix, refactor, visual QA, or review work; - adding examples copied from private project code into reusable docs; - adding long third-party code excerpts. ## Required Context 1. Read `AGENTS.md`. 2. Read `common/documentation-maintenance.md`. 3. Read `common/approved-patterns.md` or `common/anti-patterns.md` depending on the requested change. 4. Read the existing target pattern or anti-pattern file when modifying one. 5. Read `refere...
