Curator Repo-Learn Skill (v2.88)

Single Repository Pattern Extraction - Learn from a specific GitHub repository.

Role & Priorities

Priorities (ordered): accuracy → relevance → speed → coverage

Scope: Clone repository, analyze structure, extract patterns, update procedural memory.

Agent Teams Integration (v2.88)

Optimal Scenario: B (Custom Subagents)

Why Scenario B for Repo-Learn

• Independent operation: Single repo, single task
• High specialization need: Pattern recognition requires expertise
• Low coordination need: No multi-stage pipeline
• Efficient execution: Direct spawn, no team overhead

Scenario Analysis

| Criterion | Weight | Score | Rationale | |-----------|--------|-------|-----------| | Coordination Need | 25% | 2/10 | Independent operation | | Specialization Need | 25% | 9/10 | Requires pattern recognition | | Quality Gate Need | 20% | 6/10 | Moderate validation needed | | Tool Restriction Need | 15% | 3/10 | Standard tools sufficient | | Scalability | 15% | 2/10 | Single repo focus | | Total | 100% | 5.2/10 | Scenario B optimal |

Workflow (Scenario B)

yaml
# Direct Subagent Spawn
Task(subagent_type="ralph-researcher", prompt="""
Analyze repository ${REPO_URL}:

1. Clone repository (shallow)
2. Detect domain and language
3. Scan for:
   - Function/method patterns
   - Class/interface definitions
   - Configuration patterns
   - Error handling patterns
   - Testing patterns
4. Extract rules with:
   - domain: <detected>
   - category: <detected>
   - confidence: 0.75-0.95
   - source_repo: ${REPO_URL}
   - source_file: <path>
5. Update ~/.ralph/procedural/rules.json
6. Create manifest with files[] array

Return: patterns extracted, rules added, domain detected

Domain Detection (GAP-C02 FIX)

Automatic domain detection from repository content:

bash
# Domain Keywords
backend:    api, server, rest, graphql, controller, service
frontend:   react, vue, angular, component, hook, state
database:   sql, query, schema, migration, orm, prisma
security:   auth, jwt, token, encrypt, hash, csrf
testing:    test, spec, jest, vitest, mock, coverage
devops:     docker, kubernetes, ci, deploy, pipeline
hooks:      hook, lifecycle, callback, trigger, event
general:    config, util, helper, common, shared

Error Handling

| Error | Recovery | |-------|----------| | Invalid URL | Show usage, exit | | Repository not found | Suggest alternatives, exit | | Clone failure | Retry with different depth | | No patterns found | Log warning, return empty | | Rules merge failure | Restore from backup |
