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 | $0.03127 | $0.03127 |
| Opus 5.5 | $0.01251 | $0.01251 |
| Sonnet 5.5 | $0.00625 | $0.00625 |
| Haiku 4.5 | $0.00313 | $0.00313 |
Grade A, and why
product-os 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.
How it starts
The opening of the file, as written. The whole thing — 203 lines — stays where its author put it; the contents beside it link to each section on GitHub.

About {Your Company}
Conventions
- {Language preference} throughout all documents (e.g. UK English, US English)
- Strategy documents apply Reforge frameworks (activation moments, PNIP pyramid, psych framework, growth loops)
- Project/experiment documents follow the template in
pm-playbook/— always include hypothesis, evidence, success metrics, guardrails, and risks - Goals should be outcome-oriented, not deliverables. "Increase trial-to-paid from 4% to 10%" not "Launch new onboarding flow"
- Tone is direct, professional, and concise. No emojis unless explicitly asked. Avoid corporate fluff
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.
