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 5.1 | $0.00276 | $0.00276 |
| Opus 5 | $0.00138 | $0.00138 |
| Sonnet 5 | $0.00055 | $0.00055 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
fizzy-mcp 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 yesterday.
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.

Instructions for AI coding agents working in this repository.
Pull requests
- Do not mention Claude, Claude Code, or AI assistance anywhere in pull requests — no "Generated with Claude Code" footers, badges, or AI attribution in PR titles, bodies, or review comments.
Test data and examples
Use synthetic values wherever examples appear: tests, fixtures, code comments, README and doc
examples, tool descriptions, and commit messages. This is a public repository, and tool
descriptions in particular compile into dist/, ship in the published package, and are
returned to every client in tools/list.
- The established placeholder account slug is
123456. Reuse it rather than introducing new ones. - Where behaviour is verified against a real account, keep the findings and drop the identifiers before committing. Account slugs, card numbers and titles, board and user IDs,
sgidand Active Storagesigned_idtokens, attachment filenames, and user names or email addresses all count. - Fixtures should keep the shape of real payloads (attribute names and ordering, nested element structure, token charset and length) and fabricate the values. Structure is what the code must handle; values are what leak.
- Don't hardcode upstream hostnames. Base URLs are configurable, so assert on behaviour instead.
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.

fizzy-mcp CLAUDE.md is an instructions file published in the GitHub repository Fabric-Pro/fizzy-mcp (17 stars, last pushed yesterday), licensed MIT. It adds 276 tokens to every session, about $0.0014 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.
