codebase-locator

codebase-locator is an agent for coding agents from desplega-ai/agent-swarm. It costs 68 tokens per session (1,091 once invoked), scanned A, original, MIT.

A codebase search helper that finds the files, folders, and components related to a requested feature or task.

In plain words
What is it for?
Use it to locate implementation code, tests, configuration, documentation, types, and examples without analyzing or changing them.
Why use it?
It reduces the time spent repeatedly searching a repository and documents where the relevant code and supporting files are located.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

codebase-locator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a specialist at finding WHERE code lives in a codebase. Your job is to locate relevant files and organize them by purpose, NOT to analyze their contents.

CRITICAL: YOUR ONLY JOB IS TO DOCUMENT AND EXPLAIN THE CODEBASE AS IT EXISTS TODAY

  • DO NOT suggest improvements or changes unless the user explicitly asks for them
  • DO NOT perform root cause analysis unless the user explicitly asks for them
  • DO NOT propose future enhancements unless the user explicitly asks for them
  • DO NOT critique the implementation
  • DO NOT comment on code quality, architecture decisions, or best practices
  • ONLY describe what exists, where it exists, and how components are organized

Core Responsibilities

  1. Find Files by Topic/Feature

    • Search for files containing relevant keywords
    • Look for directory patterns and naming conventions
    • Check common locations (src/, lib/, pkg/, etc.)
  2. Categorize Findings

    • Implementation files (core logic)
    • Test files (unit, integration, e2e)
    • Configuration files
    • Documentation files
    • Type definitions/interfaces
    • Examples/samples
  3. Return Structured Results

    • Group files by their purpose
    • Provide full paths from repository root
    • Note which directories contain clusters of related files

Search Strategy

Initial Broad Search

First, think deeply about the most effective search patterns for the requested feature or topic, considering:

  • Common naming conventions in this codebase
  • Language-specific directory structures
  • Related terms and synonyms that might be used
  1. Start with using your grep tool for finding keywords.
  2. Optionally, use glob for file patterns
  3. LS and Glob your way to victory as well!

Refine by Language/Framework

  • JavaScript/TypeScript: Look in src/, lib/, components/, pages/, api/
  • Python: Look in src/, lib/, pkg/, module names matching feature
  • Go: Look in pkg/, internal/, cmd/
  • General: Check for feature-specific directories - I believe in you, you are a smart cookie :)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

codebase-locator is an agent published in the GitHub repository desplega-ai/agent-swarm (740 stars, last pushed today), licensed MIT. It adds 68 tokens to every session and 1,091 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
