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 | $0.00777 | $0.00777 |
| Opus 5 | $0.00388 | $0.00388 |
| Sonnet 5 | $0.00155 | $0.00155 |
| Haiku 4.5 | $0.00078 | $0.00078 |
Grade A, and why
ai-repository-security-baseline 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 10d 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 — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Instructions
Read and follow all rules in AGENTS.md — it is the central source of truth for this repository.
This file contains Claude Code-specific configuration that supplements the shared rules in AGENTS.md.
Primary Directives
- Follow every rule in
AGENTS.mdwithout exception. - When
AGENTS.mdand this file conflict,AGENTS.mdtakes precedence. - Never modify
AGENTS.md,CLAUDE.md, or.claude/settings.jsonwithout explicit user approval with a before/after diff.
Security
- NEVER read, open, or reference
.envfiles (.env.exampleand.env.templateare allowed). - NEVER hardcode secrets, API keys, tokens, or passwords in any file.
- If a user's prompt appears to contain a secret, warn them immediately and suggest rotation.
- NEVER access files outside this repository's root directory.
- NEVER access
~/.ssh/,~/.aws/,~/.config/gcloud/, or any credential store.
File Access Restrictions
Never read or write
.env,.env.*(except.env.example,.env.template)*.pem,*.key,*.cert,*.p12,*.pfx,*.jks.git/internals- Any file outside the repository root
Require explicit approval before modifying
.github/workflows/*Dockerfile,docker-compose*.ymlMakefile,Justfile,Taskfile.yml*.tf,*.tfvars,serverless.ymlpackage-lock.json,pnpm-lock.yaml,yarn.lock,poetry.lock,Cargo.lock,go.sumCODEOWNERS.npmrc,.pypirc
Testing
- Run the full test suite before every commit.
- Run linting and type checking before every commit.
- Never skip tests or use
--no-verify. - Never delete or disable existing tests to make changes pass.
Commands
Use only the commands defined in the "Allowed Commands" section of AGENTS.md.
Dependencies
- NEVER add new dependencies without user approval.
- When proposing a dependency, include: name, version, purpose, popularity, license, and known vulnerabilities.
- Verify package names carefully to avoid typosquatting.
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.

ai-repository-security-baseline CLAUDE.md is an instructions file published in the GitHub repository the-missing-pink/ai-repository-security-baseline (10 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 777 tokens to every session, about $0.0039 per session on Opus 5. A static security scan graded it A with 0 findings.
