A collection of Claude skills — reusable, packaged instructions that teach Claude how to carry out a particular kind of task. Each skill lives in its own folder with a SKILL.md (the workflow Claude follows) and any supporting reference files.
Skills work in Cowork (the Claude desktop app) and in Claude Code. See each skill's own README for install and usage details.
| Skill | Description |
|---|---|
| code-optimization | Analyze a codebase for maintainability, propose and prioritize refactors, then implement them safely on a dev branch with tracked issues and a review-ready PR. Pure refactoring only — never changes behavior or weakens security. |
| code-review | Review a pull request with a panel of independent agents, score every finding for confidence, and post only what survives the filter. Comes in two depths — a full five-dimension review, and a quick two-dimension pass for a fast look. |
Cowork: package the skill folder as a .skill file (zip -r <skill>.skill SKILL.md references), open it in Cowork, and click Save skill.
Claude Code: copy the skill folder into ~/.claude/skills/ (personal) or .claude/skills/ (per-project). The folder must contain SKILL.md.
Each skill's README has the full details.
