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 | $0.00159 | $0.00159 |
| Opus 5.5 | $0.00064 | $0.00064 |
| Sonnet 5.5 | $0.00032 | $0.00032 |
| Haiku 4.5 | $0.00016 | $0.00016 |
Grade A, and why
fullstack-langgraph-nextjs-agent 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.
What it actually says
CLAUDE.md
This project uses AGENTS.md as the single source of truth for agent guidance.
Everything Claude Code needs — development commands, architecture overview, data flow, project-specific patterns, and the installed agent skills — lives in AGENTS.md.
Read AGENTS.md before working in this repository, and put any new guidance there rather than
here, so every coding agent (Claude Code, Cursor, Codex, and anything else that reads the AGENTS.md
convention) picks it up. This file exists only so that tools looking specifically for CLAUDE.md are
pointed to the right place.
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.
