Core Capability: Lightning-fast codebase navigation using local Node.js indexing. Zero Cost: Runs locally. No API calls.
Rule: BEFORE reading any file content to understand logic, you MUST use FastCode.
Run the internal Node.js script. Do not ask user to install anything.
node cli/skills/fastcode.js search "your_query_here"
The script returns a JSON list of most relevant files.
If search returns nothing or "Index not found", run indexing first:
node cli/skills/fastcode.js index
You can also run this manually if you want:
node cli/skills/fastcode.js search "auth"
