 "title": "Map a codebase so Claude finds callers in one call",
 "page_title": "How to map a codebase so Claude finds callers in one call with Claude DB",
 "summary": "Index an existing project so Claude can see what defines, calls or imports a symbol.",
 "who": "A developer or reviewer who inherits a TypeScript, Python, Go, Rust, Java, Kotlin or JavaScript codebase and needs to trace where a function is used.",
 "problem": "Without a map, Claude runs grep and reads many files to work out what calls what, which is slow and often incomplete.",
 "outcome": "Claude answers who defines, calls or imports a symbol in a single lookup, with the map built from your existing code.",
 "steps": [
  "`npm install -g claude-db`",
  "`cd your-project`",
  "`claude-db install --project`",
  "Run `claude-db scan` to map the existing code into memory.",
  "In Claude Code, run `/cdb-scan` if you want to map the codebase from inside a chat, then ask who calls a function you choose."
 ],
 "agent_prompt": "In the repo <repo-path>, after running claude-db scan, ask Claude Code who defines, calls and imports the symbol <symbol-name>. Expected output is a list of definition and call sites. Verify at least one listed site with grep before trusting the result.",
 "agents": [
  "claude-code"
 ],
 "difficulty": "Intermediate",
 "time": "15 minutes",
 "basis": "readme",
 "caveat": "The README notes that plain grep wins in some cases, so check Claude DB results against grep when precision matters.",

 "lang": "typescript",
 "requirements": [
  "Node 22.16 or newer",
  "A git repository for your project",
  "Claude Code installed and able to run hooks",
  "Optional: a Postgres or MongoDB database if you want to share memory across machines"
