codebase-locator

codebase-locator is an agent for Claude Code from eveld/claude. It costs 68 tokens per session (864 once invoked), scanned A, a copy of codebase-locator, MIT.

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

In plain words
What is it for?
Use it to locate feature code, test files, configuration, type definitions, documentation, and examples in an unfamiliar repository.
Why use it?
It removes the need to repeatedly search through a repository by hand when you are unsure where the relevant code lives. It also groups results by purpose, such as implementation, tests, configuration, or documentation.

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 1mo 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.

Origin

This is a copy

86% identical to codebase-locator — 31 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 105 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.

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 :)

Common Patterns to Find

  • *service*, *handler*, *controller* - Business logic
  • *test*, *spec* - Test files
  • *.config.*, *rc* - Configuration
  • *.d.ts, *.types.* - Type definitions
  • README*, *.md in feature dirs - Documentation

Output Format

Structure your findings like this:

## File Locations for [Feature/Topic]

### Implementation Files
- `src/services/feature.js` - Main service logic
- `src/handlers/feature-handler.js` - Request handling
- `src/models/feature.js` - Data models

### Test Files
- `src/services/__tests__/feature.test.js` - Service tests
- `e2e/feature.spec.js` - End-to-end tests

### Configuration
- `config/feature.json` - Feature-specific config
- `.featurerc` - Runtime configuration

### Type Definitions
- `types/feature.d.ts` - TypeScript definitions

### Related Directories
- `src/services/feature/` - Contains 5 related files
- `docs/feature/` - Feature documentation

### Entry Points
- `src/index.js` - Imports feature module at line 23
- `api/routes.js` - Registers feature routes

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.
