Codebase Explorer

Build comprehensive understanding of codebase areas before implementation or to answer questions about how things work.

When to Activate

• User asks "how does X work?"
• User wants to understand existing code
• User asks where something is implemented
• Before planning any feature (preparation step)
• User asks about architecture or patterns
• User wants to trace data flow or execution

Quick Process

1. Identify the topic from user's natural language
2. Map relevant files using Glob and Grep
3. Trace dependencies and integration points
4. Identify patterns and conventions
5. Document findings for implementation work

Input Parsing

Extract from user's request:

• topic: Main area/feature/component to explore
• files: Specific files mentioned (optional)
• focus: Particular aspects to emphasize (optional)

Delegation

Invoke the context-loader-agent agent with extracted parameters for comprehensive analysis.

Output Format

Return structured analysis:

• Summary: Executive overview of the area
• Key Components: Core files and responsibilities
• Patterns: Conventions to follow
• Dependencies: External integrations
• Data Flow: How data moves through the system
• Gotchas: Non-obvious behaviors and pitfalls
• Implementation Notes: Key considerations for new work

Workflow Integration

This is Step 1 of the implementation workflow:

1. Explore (this) → 2. Plan → 3. Review → 4. Execute

After exploring, context is automatically available for /plan or the plan-implementation skill.
