Repomix (Codebase Packaging)

Use Repomix to pack entire codebases into a single, context-optimized format for analysis.

Tools

Tool Purpose

repomix_pack_codebase

Pack local codebase

repomix_pack_remote_repository

Pack a GitHub repository

repomix_grep_repomix_output

Search within packed output

repomix_read_repomix_output

Read sections of packed output

Packing a Remote Repository

repomix_pack_remote_repository({ remote: "https://github.com/5dlabs/my-project", branch: "develop" })

Returns a packed representation of the entire codebase.

Searching Packed Output

After packing, search for specific patterns

repomix_grep_repomix_output({ pattern: "authentication", output_id: "abc123" })

Reading Specific Sections

repomix_read_repomix_output({ output_id: "abc123", start_line: 100, end_line: 200 })

Use Cases

Task Approach

PRD Analysis Pack repo to understand existing architecture

Code Review Pack to see full context of changes

Task Planning Pack to understand dependencies

Integration Pack multiple repos for merge planning

Best Practices

• Pack before planning - Understand the codebase first

• Use grep for navigation - Don't read everything

• Focus on relevant sections - Use start/end lines

• Cache outputs - Reuse packed output for multiple queries
