Context Hunter skill

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
