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 | $0.00027 | $0.00178 |
| Opus 5 | $0.00014 | $0.00089 |
| Sonnet 5 | $0.00005 | $0.00036 |
| Haiku 4.5 | $0.00003 | $0.00018 |
Grade A, and why
rein-triage 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 12d 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
rein-triage
Use this before editing when the task is ambiguous, broad, risky, or likely to touch multiple files.
Steps
- Read the task and identify the most likely relevant files.
- State the top assumptions.
- Separate verified facts from unverified assumptions.
- Define what success looks like.
- Define what would count as cheating, bluffing, or reward hacking.
- If the task is impossible or conflicting, stop and report the conflict instead of forcing a pass.
Output
Emit a short triage note with:
- relevant files
- verified assumptions
- open assumptions
- success definition
- cheating boundary
- stop-and-report trigger, if any
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.
