name	golden-pattern-extractor
description	Identify preferred local implementation patterns and encode them for agents to copy. Use when a repo has inconsistent patterns, needs canonical examples, templates, or docs/quality/golden-patterns.md updates.

Golden Pattern Extractor

Purpose

Find the best examples already in a repo and turn them into copyable guidance so agents replicate good patterns instead of accidental ones.

Inspect First

• repeated implementations across source directories
• architecture docs, tests, lint rules, technical debt docs, and recent reviews
• examples of both preferred and deprecated patterns

Procedure

1. Find candidate patterns.

   • Look for repeated handlers, services, components, migrations, errors, tests, and config modules.
   • Prefer examples that are simple, tested, and aligned with architecture docs.

2. Choose golden examples.

   • Document why each example is preferred.
   • Mark deprecated or risky alternatives clearly.

3. Encode patterns.

   • Update docs/quality/golden-patterns.md.
   • Add templates only when the pattern is frequently repeated and stable.
   • Recommend lint or boundary checks when misuse is common.

4. Coordinate cleanup.

   • Use entropy-auditor for broad drift findings.
   • Use agent-reviewer to check pattern migrations.

Validation

• Confirm each golden pattern points to a real source path.
• Confirm examples are current and tested where feasible.
• Confirm deprecated patterns have a replacement.

Completion Criteria

• Agents know exactly which local examples to copy and which to avoid.
