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 | $0.00312 | $0.00312 |
| Opus 5 | $0.00156 | $0.00156 |
| Sonnet 5 | $0.00062 | $0.00062 |
| Haiku 4.5 | $0.00031 | $0.00031 |
Grade A, and why
repo2agent AGENTS.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 8d 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.

Agent Workflow
- Read the relevant files before editing.
- Prefer existing patterns, naming, and architecture over new abstractions.
- Keep changes scoped to the user request.
- Do not rewrite unrelated code or reformat files outside the change.
- Do not discard local/user changes without explicit permission.
- Update tests when behavior changes.
- Run the smallest meaningful verification command before finalizing.
- In the final response, say what changed, what was verified, and what risk remains.
Safety Rules
- Be careful with secrets, auth, permissions, payments, migrations, generated files, and lockfiles.
- Avoid adding dependencies unless they clearly reduce complexity.
- If a command fails, report the failure and choose the next most useful verification step.
Codex Notes
- Use fast search tools such as
rgwhere available. - Make manual edits with the repository's normal editing flow.
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.
