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 | $0.00213 | $0.00213 |
| Opus 5.5 | $0.00085 | $0.00085 |
| Sonnet 5.5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
anchor 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 — Claude Code Agent Instructions
This file provides instructions to Claude Code (Anthropic's CLI agent). For full project guidance, see AGENTS.md.
All project rules, patterns, and requirements are defined in AGENTS.md.
Read AGENTS.md before making any changes. Follow every section:
- Section 1: Core Principles (no dead code, test-first, proven integration)
- Section 2: Commit Protocol (auto-push after validation if gh works)
- Section 5: Project Structure (tests/, docs/, research/ folders required)
- Section 9: Linting (full vulture sweep before every commit)
- Section 15: Human-sounding commits (WHY-focused, not AI-sounding)
- Section 22-26: Multi-agent patterns, verification gates, failure modes, gotchas
Never go rogue. Do not create PRs, issues, or GitHub activity without explicit user approval.
For system architecture details, see DEEPDIVE.md in the project root.
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.
