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 | $0.00000 | $0.00160 |
| Opus 5 | $0.00000 | $0.00080 |
| Sonnet 5 | $0.00000 | $0.00032 |
| Haiku 4.5 | $0.00000 | $0.00016 |
Grade A, and why
pr-review 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 7d 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
Review the current branch changes and suggest PR content.
- Get the current branch and base branch:
git branch --show-current
git log --oneline main..HEAD
git diff main...HEAD --stat
- Analyze the changes:
- Summarize what changed (new features, bug fixes, refactoring, etc.)
- Identify which parts of the monorepo are affected (lib/, web/, or both)
- List the key files modified
- Generate a PR description with:
- Title: Concise summary of the changes
- Summary: 2-3 bullet points explaining the changes
- Test plan: How to verify the changes work correctly
Present the suggested PR content for the user to review and modify.
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.

pr-review is a command published in the GitHub repository princeton-ddss/blackfish (24 stars, last pushed 11d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 160 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
