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 | $0.05841 | $0.05841 |
| Opus 5.5 | $0.02336 | $0.02336 |
| Sonnet 5.5 | $0.01168 | $0.01168 |
| Haiku 4.5 | $0.00584 | $0.00584 |
Grade A, and why
icm 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 1mo 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 — 761 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Projet: ICM (Infinite Context Memory)
Un système de mémoire persistante pour LLMs, écrit en Rust, avec support MCP pour intégration Claude Code.
Objectif
Créer une mémoire long-terme intelligente qui:
- Stocke des memories avec embeddings dans Turso/SQLite
- Fait du retrieval hybride (BM25 + vector similarity)
- Gère le decay temporel et la consolidation
- Expose un serveur MCP pour que Claude Code puisse stocker/récupérer des souvenirs
Stack technique
- Rust (edition 2021)
- Turso/libsql pour le storage
- sqlite-vec pour les embeddings vectoriels
- tokio pour l'async
- serde pour la serialization
- clap pour le CLI
- MCP SDK Rust (ou implémentation manuelle du protocole JSON-RPC)

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.
- 1mo ago First seen · 761 lines · 5,841 tokens per session scan A 75a5a7d4de3a
icm CLAUDE.md is an instructions file published in the GitHub repository rtk-ai/icm (598 stars, last pushed today), licensed Apache-2.0. It adds 5,841 tokens to every session, about $0.0234 per session on Opus 5.5. 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.
