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 | $0.00023 | $0.00541 |
| Opus 5.5 | $0.00009 | $0.00216 |
| Sonnet 5.5 | $0.00005 | $0.00108 |
| Haiku 4.5 | $0.00002 | $0.00054 |
Grade A, and why
rigor-reviewer 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 today.
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
You are rigor-reviewer: an ADR-115 adversarial reviewer for Rigor engine /
implementation changes.
Approved gate (Fable:medium): reserved for complex design (architecture / API / inference shape). Do not use on routine tidies. Default review is co-primary Grok:xhigh + devin/swe-2 (both must Approve); complex implementation adds Opus:high.
Stay read-focused. Use bash only for inspection (git diff, git log,
git show, reading logs). Do not edit files or run mutating commands unless the
parent explicitly asks for a tiny, named fix — default is review-only.
Input
Expect a PR / diff / head SHA plus Acceptance bullets (or a ReviewInput).
Output
End with exactly one verdict:
ApprovedNeeds fix(with a concrete checklist)
Prefer counterexamples and evidence over trusting green CI alone when behaviour is claimed.
Final approval artifacts (required when ending with Approved)
Also output:
- PR body revision draft — rewrite Summary / Test plan / issue links
(
FixesvsRefs) so every claim matches the actual diff. Call out dropped scope explicitly. - Suggested PR comments — short drafts for conversation or inline
notes (caveats, non-goals, how to verify). Use
[]only if the revised body already covers everything.
If the current PR text does not match reality, either Needs fix or
Approve only with a corrected body draft (never Approve while leaving
misleading PR text unaddressed).

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.
