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 | $0.00226 | $0.00226 |
| Opus 5 | $0.00113 | $0.00113 |
| Sonnet 5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00023 | $0.00023 |
Grade A, and why
code-index CLAUDE.md 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 3d 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.
What it actually says
Code navigation
This repo has a code index exposed via MCP. Retrieval tools: code_search,
symbol_lookup, file_outline, module_outline, where_am_i,
get_symbol_body, get_symbol_bodies, callers, callees, references,
trace, file_imports, recent_changes, propose_rename. Admin: admin
(with op=init|setup_check|install_hook|stats|verify).
- For ANY discovery task ("where is X", "what calls Y", "find the code that..."), use the index tools. Do not Read or Grep to explore.
- Read files only AFTER the index has identified the exact path.
- Use
file_outlineinstead of Read when you only need to know what's in a file. - For exact identifiers (camelCase, snake_case, ALL_CAPS), use
symbol_lookup. For conceptual queries, usecode_search. - The index auto-updates on
Edit/Write/MultiEdit; you don't need to refresh it.
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.

code-index CLAUDE.md is an instructions file published in the GitHub repository achreftlili/code-index (1 stars, last pushed 3mo ago), licensed MIT. It adds 226 tokens to every session, about $0.0011 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.
