pr-review

pr-review is a skill for Codex from ashermahonin/agentic-skills. It costs 72 tokens per session (460 once invoked), scanned A, original, MIT.

A read-only review of a pull request or local code changes. It checks behavior, regressions, tests, security, compatibility, migrations, performance, accessibility, operations, and documentation.

In plain words
What is it for?
Use it before merging or releasing changes, or whenever you need a risk-focused review of a diff.
Why use it?
It finds defects and maintenance risks before code is merged, pushed, or released. Findings include their severity, location, impact, and a direction for fixing them.

Token cost

What it costs to keep this loaded

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.

Security

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 10d 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

PR Review

Purpose

Find defects and material maintenance risks before a change lands. Review behavior first; style matters only when it obscures correctness or raises change cost.

Change context

  • Identify changed files and intent of the change.
  • Find affected flows, contracts, data, security boundaries, and tests.
  • Read the diff with the old behavior in mind.
  • Look for missing validation and docs drift.

Change method

  1. Reconstruct the intended behavior from the request, diff, tests, and nearby contracts.
  2. Trace correctness, failure handling, concurrency, compatibility, migration, and rollback effects.
  3. Check authorization, secrets, privacy, untrusted input, and destructive operations where relevant.
  4. Use engineering-quality criteria for responsibilities, dependencies, side effects, errors, and tests; do not turn preferences into findings.
  5. Review performance and operations when shared or hot paths changed.
  6. Report findings by severity with a tight file/line reference, concrete impact, and fix direction. If none are found, state residual risk and checks not run.

Engineering constraints

  • Keep review read-only unless the user also asks for fixes.
  • Verify uncertain external behavior with current documentation before raising a finding.
  • Do not approve behavior you could not reconstruct from code and evidence.

Evidence

  • Prioritized findings with evidence
  • Open questions and assumptions
  • Missing or unrun validation
  • Residual risk and merge recommendation

Ready when

  • Findings lead the response and are ordered by impact.
  • Every finding describes a plausible failure, not a hypothetical preference.
  • Line references are as narrow as the evidence permits.
  • A clean review still reports test gaps and residual risk.

Handoff

Hand off actionable findings to implementation or release decision with severity and evidence.

References

  • references/review-checklist.md: Use this checklist for reviews.
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
