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 | $0.03297 | $0.03297 |
| Opus 5.5 | $0.01319 | $0.01319 |
| Sonnet 5.5 | $0.00659 | $0.00659 |
| Haiku 4.5 | $0.00330 | $0.00330 |
Grade C, and why
amadeus CLAUDE.md scanned grade C with 2 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 2mo 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 97 lines — stays where its author put it; the contents beside it link to each section on GitHub.
To avoid collisions with other agents, always create a dedicated worktree and branch and switch to them before starting work.
Project Instructions
- Communicate with the user in Japanese.
- Write documentation in English by default.
- As an exception, write
amadeus/**/*.mdin Japanese. - Write code comments in English.
- Write commit messages in English.
- If you find violations of these language rules while working, fix them as part of the same change.
Fable 5 Delegation Policy
To avoid hitting the Fable 5 rate limit prematurely, reserve the main session for requirements clarification, design, planning, audits, reviews, and final integration decisions. During implementation, delegate well-scoped execution tasks to subagents whenever the expected resource savings exceed the coordination overhead:
- Use Sonnet for routine implementation with clear boundaries.
- Use Opus for complex or high-risk implementation that requires stronger reasoning.
- Use Fable 5 directly for exceptionally difficult or tightly coupled work that cannot be delegated safely or efficiently. Keep small, well-scoped tasks in the main session when delegation overhead would exceed the expected resource savings.
Every delegation prompt must define the scope, owned files, acceptance criteria, and verification steps. Assign non-overlapping write scopes. The Fable 5 main session remains responsible for reviewing the complete diff, confirming final verification, and deciding whether the integrated result is acceptable.

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.

amadeus CLAUDE.md is an instructions file published in the GitHub repository amadeus-dlc/amadeus (9 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 3,297 tokens to every session, about $0.0132 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
