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 | $0.00198 | $0.00198 |
| Opus 5.5 | $0.00079 | $0.00079 |
| Sonnet 5.5 | $0.00040 | $0.00040 |
| Haiku 4.5 | $0.00020 | $0.00020 |
Grade A, and why
repopact 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 2mo 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 Project Instructions
Read AGENTS.md before doing any work in this repository.
AGENTS.md is the binding project contract. Follow it over this file when there is overlap.
Required behavior:
- Re-read
AGENTS.mdat the start of each implementation session. - Check for child
AGENTS.mdfiles in the directories being edited. - Keep all durable documentation under
docs/except the allowed root files. - Update
docs/developers/task-logs.mdafter every meaningful task, fix, feature, or documentation change. - Use
docs/plan/specs.md,docs/plan/design.md, anddocs/plan/tasks.mdfor planned work. - Run relevant checks before committing.
- Do not add AI signatures, co-author trailers, generated-by notes, or tool metadata.
- GPG signing is not required.
If a task conflicts with AGENTS.md, stop and ask the project owner for direction.
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.
