# Prompt Library Skill

Extract and save effective prompts from work sessions.

## Process

1. **Scan session** for prompts that:
   - Achieved the desired outcome efficiently
   - Used clever techniques or patterns
   - Could be reused for similar tasks
   - Demonstrated good prompt engineering

2. **Categorize** each prompt:
   - `CODE` - Code generation, refactoring, debugging
   - `REVIEW` - Code review, architecture analysis
   - `DOCS` - Documentation, READMEs, comments
   - `TEST` - Test generation, coverage
   - `DEPLOY` - CI/CD, packaging, deployment
   - `DESIGN` - UI/UX, system design
   - `DATA` - Data processing, analysis
   - `META` - Prompts about prompting

3. **Extract template** - generalize specifics into placeholders

4. **Pre-write format-match check** (mandatory):
   - Run `grep -E '^### P-' ~/projects/DecisionLog/PROMPTS.md | head -3` to confirm the target file already contains `P-YYYYMMDD-###` entries.
   - If the file has zero `P-` entries OR has entries in a different format (e.g., named templates without P-IDs), STOP. The destination has drifted. Surface to user: "PROMPTS.md format doesn't match the skill's catalog shape (P-IDs + Category field). Which file should I write to, or should we re-route the skill?"
   - This catches path-drift before silently writing into the wrong file. Discovered 2026-05-23 — the public-notes `PROMPTS.md` is a *templates* file, NOT a catalog; writing P-ID entries there would corrupt it.

5. **Append to** `~/projects/DecisionLog/PROMPTS.md` (in the private repo `AreteDriver/DecisionLog`). This is the skill's design target: P-IDs + Category field + the same CODE/REVIEW/DOCS/TEST/DEPLOY/DESIGN/DATA/META vocabulary as the Categories table above. A separate file at `~/projects/notes/PROMPTS.md` exists for *named template scaffolds* (Universal, CI/CD Diagnostic, GitHub Profile, etc.) — that one is hand-maintained, not a /prompt-library target.
