ABOUTME Index

Read .claude/aboutme-index.json to find files by purpose instead of grep-searching.

Usage

  1. Read the index:
cat .claude/aboutme-index.json
  1. Filter by keyword using jq:
cat .claude/aboutme-index.json | jq 'to_entries[] | select(.value | test("auth|jwt"; "i"))'
  1. Read the relevant files.

Commands

Command Description
/aboutme-check Find files missing ABOUTME headers
/aboutme-rebuild Rebuild the entire index
/aboutme-stale Check for stale headers
cat .claude/aboutme-index.json Read the index directly

Index Format

{
  "app/src/auth.py": "JWT authentication module for AWS Cognito access tokens...",
  "app/src/config.py": "Centralized configuration using Pydantic settings..."
}

The index is auto-rebuilt on session start and updated incrementally on file edits.
