claude-skills-reference
Snapshot of Claude Code skills, copied here as a reference for Jerry to study how Anthropic structures task-specific guidance for a coding agent.
These are not Jerry's own skills — they're examples of the pattern. Each skill is a directory with a SKILL.md (instructions to the agent) plus optional supporting files (references, hooks, templates).
What's here
| Skill | Source | What it does |
|---|---|---|
caveman/ |
caveman plugin |
Ultra-compressed communication mode — drops articles, filler, pleasantries. Three intensity levels (lite / full / ultra) plus three classical-Chinese variants. |
caveman-commit/ |
caveman plugin |
Generates conventional-commit messages with the same compression discipline. ≤50 char subject, body only when "why" isn't obvious. |
caveman-review/ |
caveman plugin |
Compressed PR review comments. One line each: location, problem, fix. |
compress/ |
caveman plugin |
Compresses natural-language memory files (CLAUDE.md, todos) into the caveman format. Saves input tokens. |
mermaid/ |
Anthropic built-in | Generates Mermaid diagrams from prose requirements. Supports 18+ diagram types with per-type reference docs under mermaid/references/. |
Pattern worth borrowing
Each skill has a top-level SKILL.md that:
- States the trigger ("when user says X, or invokes /Y")
- Defines the rules (what to do, what NOT to do)
- Gives worked examples (before/after, good/bad)
- Lists boundaries (when to deactivate / when not to apply)
The mermaid skill goes further: it has a per-diagram-type references/ directory the agent loads on demand, so the SKILL.md stays small while the catalogue can be large.
For Jerry's review work, the same shape would help — one code-review-skill/SKILL.md listing the playbook rules, with references/<topic>.md files the agent loads when the review touches that topic (e.g. references/go-concurrency.md, references/auth.md).
How Jerry could use these
- Read
SKILL.mdfiles to see how compact, behavior-changing instructions look. The caveman skills in particular cram a behavior change into ~50 lines without sacrificing precedence rules. - Steal the trigger pattern: a one-line "when the user / agent does X, do Y" at the top of every skill makes the agent's behavior predictable.
- Steal the "examples" pattern: every skill has before/after examples. Concrete examples > abstract rules.
