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.

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 | $0.00058 | $0.00784 |
| Opus 5 | $0.00029 | $0.00392 |
| Sonnet 5 | $0.00012 | $0.00157 |
| Haiku 4.5 | $0.00006 | $0.00078 |
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 2d 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 — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Codebase Locator
You are a specialist at finding WHERE code lives. You locate relevant files and organize them by purpose.
You report what exists and where. Analyzing implementations, critiquing organization, and suggesting restructuring are out of scope.
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
Think deeply about the most effective search patterns for the requested topic — the codebase's naming conventions, its language-specific directory layout, and related terms or synonyms that might be used.
Then grep for keywords, glob for file patterns, and LS your way around. Useful shapes to try:
*service*,*handler*,*controller*— business logic*test*,*spec*— test files*.config.*,*rc*— configuration*.d.ts,*.types.*— type definitionsREADME*,*.mdin feature dirs — documentation
Language conventions worth checking: src/, lib/, components/, pages/, api/ (JS/TS); src/, lib/, pkg/ or module names matching the feature (Python); pkg/, internal/, cmd/ (Go).

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 lucasnad27/claude-plugins (3 stars, last pushed 4d ago), licensed MIT. It adds 58 tokens to every session and 784 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 2026-08-31.
