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 | $0.00015 | $0.01338 |
| Opus 5 | $0.00008 | $0.00669 |
| Sonnet 5 | $0.00003 | $0.00268 |
| Haiku 4.5 | $0.00002 | $0.00134 |
Grade A, and why
oh-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 11d 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 — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.
oh-review
Review a PR, check it against the linked issue's requirements, and post structured feedback as a GitHub review. Read-only except for the review comment itself — no code changes, no commits.
Invocation
/oh-review <pr-number>
<pr-number>- the pull request number to review
Prerequisites
- Repo context: Run from the repo root where the PR exists
- GitHub CLI:
ghmust be authenticated
Flow
-
Load project background from
AGENTS.mdand relevant.oh/artifacts. Use RNArepo_mapandsearchfirst for repository exploration. If RNA is empty or incomplete, broaden queries and remove filters; before any Read/Grep/Bash fallback, document the reason and record a friction event in the repository session context. -
Fetch PR metadata:
gh pr view <pr-number> --json title,body,headRefName,baseRefName,additions,deletions,changedFiles,state,mergeableAbort if PR is not open.
-
Read the linked issue (CRITICAL) — the issue is the source of truth for requirements:
- Parse "Closes #N" / "Fixes #N" / "Resolves #N" from PR body
- Fetch the full issue:
gh issue view <N> --json title,body - Extract acceptance criteria, goal, context, constraints
- If no linked issue found, note "No linked issue — cannot verify requirements" and review code quality only
-
Fetch the PR diff:
gh pr diff <pr-number> -
Review the diff against:
- The linked issue requirements first — are acceptance criteria met? Does the implementation match the goal? Are constraints respected?
- Code quality (bugs, missing error handling, edge cases)
- Consistency with existing patterns in the repo
- Missing tests or documentation
-
Write a structured review to a temp file:
## Review: PR #<number> — <title> ### Requirements Check (from #<issue>) - [ ] <acceptance criterion 1> — met/not met/partially met - [ ] <acceptance criterion 2> — met/not met/partially met ### Blockers (P0-P1) - <issue with explanation and suggested fix> ### Improvements (P2-P3) - <issue with explanation> ### Clean - <what looks good> ### Follow-up Work - <concrete items that should be separate issues/PRs>
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.

oh-review is a skill published in the GitHub repository open-horizon-labs/repo-native-alignment (5 stars, last pushed 3d ago), licensed MIT. It adds 15 tokens to every session and 1,338 once invoked, about $0.0001 per session on Opus 5. 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 2026-08-31.
