Memory Consolidation Skill - Pattern Extraction & Deduplication

## Code Review ### Spec Pattern Search (REQUIRED) - Searched for existing spec patterns: `find spec -name "*spec.rb" | sort` - Found existing spec files matching existing skill patterns - Similar patterns found: Skill files are documentation, not production code requiring specs ### Test Results - Test suite run: `bundle exec rspec` - Results: **701 examples, 2 pre-existing failures, 10 pending** - Failures are UNRELATED to this PR (dashboard_spec.rb UI issues, orchestrator_ping_job_spec.rb syntax error) ### Spec Coverage Check - Files changed: - `.claude/skills/memory-consolidation/SKILL.md` (NEW - skill documentation) - Required specs: **N/A** - This is a documentation/skill file, not production code - Explanation: - Skill files provide guidance/ workflows for agents - They use existing MCP tools (search_memory, store_memory, create_proposal) that are already tested - No new executable code added - Follows existing skill file patterns (git-workflow, memory, orchestrator-workflow, etc.) ### Findings - **Code quality**: Comprehensive, well-structured skill documentation - **Format**: Follows established skill file patterns with YAML frontmatter - **Content quality**: - Clear WHEN/WHY/HOW structure - Multiple real-world examples with before/after - Clustering strategies and quality checklists - Metadata standards for traceability - Safety features (human approval via proposal system) - **Security**: Uses existing tools with proper permissions; no new attack surface - **Implementation**: - Workflow: Researcher identifies duplicates → creates consolidated memory → creates cleanup proposal → human verifies/approves - Prevents data loss with metadata tracking (`consolidated_from` IDs) - Integrates with existing proposal system for safety - **Breaking changes**: None ### Decision **PASS** - Well-written skill documentation following existing patterns. The skill provides systematic guidance for memory consolidation using only existing tools. No test coverage required for documentation/guidance files. The test failures are pre-existing and unrelated to this PR.
