.claude/skills/context-hunter/# Context Hunter Before writing code, investigate how similar problems are already solved in this codebase. ## Before Implementation ### Discover Existing Patterns 1. **Find analogous features**: Search for code that solves similar problems. Study it before proposing your approach. 2. **Trace data flow**: How does similar data move through the system? Note caching, validation, and error handling patterns. 3. **Identify utilities**: Search for existing helpers before creating new ones. ### Detect Unwritten Conventions Look for implicit rules encoded in the codebase: - **Schema patterns**: `deleted_at` columns indicate soft-deletion. Audit columns indicate tracking requirements. - **Naming patterns**: Note consistency in `user_id` vs `userId` vs `userID`. - **Test patterns**: What's tested thoroughly reveals team priorities. ### Verify Assumptions - Run the test suite to understand current state - Check linter and formatter configs - Read recent commits in affected areas - Examine database schemas for constraints ## During Implementation ### Match Existing Code Your changes should be indistinguishable from existing code: - Use the same patterns, abstractions, and utilities - Follow the same error handling approach - Respect module boundaries - Match naming conventions exactly ### Surface Concerns When you discover conflicts between requirements and existing patterns: - Ask clarifying questions before proceeding - Flag risks you've identified - Offer alternatives that align with codebase conventions ## Checklist Before proposing changes, confirm: - [ ] Studied analogous features in the codebase - [ ] Checked for reusable utilities - [ ] Reviewed test patterns for similar functionality - [ ] Noted naming and schema conventions - [ ] Verified approach matches existing patterns
