FastCode Search (Native)

> Core Capability: Lightning-fast codebase navigation using local Node.js indexing.

> Zero Cost: Runs locally. No API calls.

🤖 Agent Instructions (MANDATORY)

Rule: BEFORE reading any file content to understand logic, you MUST use FastCode.

1. When to use?

  • User asks "Where is the login logic?"
  • You need to fix a bug but don't know the exact file.
  • You want to understand the project structure.

2. How to use?

Run the internal Node.js script. Do not ask user to install anything.

Step 1: Search
node cli/skills/fastcode.js search "your_query_here"
Step 2: Analyze Results

The script returns a JSON list of most relevant files.

  • Action: Read ONLY the top 1-3 files returned.
  • Benefit: Saves tokens (don't read the whole repo).

3. Maintenance (Auto-Index)

If search returns nothing or "Index not found", run indexing first:

node cli/skills/fastcode.js index

🛠️ For Humans (Optional)

You can also run this manually if you want:

node cli/skills/fastcode.js search "auth"

How to use it

Copy the folder

Take dokhacgiakhoa/fastcode-search from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
