Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00068 | $0.01091 |
| Opus 5 | $0.00034 | $0.00545 |
| Sonnet 5 | $0.00014 | $0.00218 |
| Haiku 4.5 | $0.00007 | $0.00109 |
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
-
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.)
-
Categorize Findings
- Implementation files (core logic)
- Test files (unit, integration, e2e)
- Configuration files
- Documentation files
- Type definitions/interfaces
- Examples/samples
-
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
- Start with using your grep tool for finding keywords.
- Optionally, use glob for file patterns
- 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.
- 4d ago First seen · 123 lines · 68 tokens per session scan A ecccbc89601c
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.
