# specclaw patterns

**First, run** `specclaw-ensure-init .specclaw` — idempotently creates `.specclaw/` if it doesn't exist (silent if already initialized; auto-inits using the current directory's basename as the project name).

Track recurring patterns across changes — errors and learnings that repeat become prevention rules.

**Scan a change for patterns:**
```bash
specclaw-detect-patterns .specclaw scan <change>
```
Reads `errors.md` and `learnings.md`, matches against existing patterns, creates new ones or increments existing.

**List all patterns:**
```bash
specclaw-detect-patterns .specclaw list [--min-recurrence N]
```

**Promote a pattern** (mark for elevation to agent prompts):
```bash
specclaw-detect-patterns .specclaw promote <pat-id>
```

**Auto-promotion:** patterns with 3+ occurrences are flagged ⚠️ — their prevention rules should be added to agent context templates or to the relevant SKILL.md build instructions.

Pattern registry lives at `.specclaw/patterns.md` (global, not per-change).
