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 | $0.03465 | $0.03465 |
| Opus 5.5 | $0.01386 | $0.01386 |
| Sonnet 5.5 | $0.00693 | $0.00693 |
| Haiku 4.5 | $0.00347 | $0.00347 |
Grade A, and why
symfony-flex-backend 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.
How it starts
The opening of the file, as written. The whole thing — 392 lines — stays where its author put it; the contents beside it link to each section on GitHub.
What is this?
CLAUDE.md is the long-form AI assistant guide for this repository. It provides
project context, architecture expectations, workflow conventions, and practical
rules for making Symfony backend changes that stay aligned with repository
standards.
This repository is a production-ready Symfony JSON REST API backend template with Docker setup for local development. It is designed to be consumed by frontend applications or other backend services.

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.
