pr-reviewer

pr-reviewer is a skill for Claude Code, Codex from codebygarv/Ai-skills. It costs 45 tokens per session (484 once invoked), scanned A, original, MIT.

A pull-request review helper that examines a complete set of code changes, rather than just one function, and reports findings by severity.

In plain words
What is it for?
Use it before approving a pull request to review intent, changed-file interactions, test coverage, migration safety, and whether unrelated work should be split out.
Why use it?
It checks whether the change matches its stated purpose and scope while also looking for bugs, missing tests, compatibility risks, and maintainability problems.

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-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 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.

How it starts

The opening of the file, as written. The whole thing — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Review a pull request the way a senior engineer would: assess whether the change accomplishes its stated intent, is appropriately scoped, and doesn't introduce bugs, architectural drift, or maintainability regressions — then organize findings by severity like a real PR review.

When to Use

  • Reviewing a complete PR/diff (multiple files, a coherent change set) rather than a single function.
  • Before approving or requesting changes on a real PR.

Differs from Code Reviewer: Code Reviewer is line/function-level quality; PR Reviewer additionally evaluates scope, intent-match, and whether the PR is the right size and shape as a unit of change.

What to Analyze

  1. Intent match — does the diff actually do what the PR title/description claims, completely?
  2. Scope — is the PR doing one coherent thing, or mixing unrelated changes that should be separate PRs?
  3. Correctness — bugs, logic errors, edge cases across the changed files, including interactions between changed files.
  4. Test coverage — are the changed code paths covered by new or existing tests? Is anything risky shipped untested?
  5. Backward compatibility / migration safety — does this break existing callers, APIs, or data assumptions?
  6. Maintainability — does this diff make the codebase easier or harder to work in going forward?

Output Format

  • One-line summary of what the PR does and whether it appears to accomplish it.
  • Findings grouped by severity: BlockingShould FixNitQuestion (things worth asking the author, not necessarily wrong).
  • Each finding references the specific file and, where possible, the line or hunk.
  • A final verdict: Approve / Approve with comments / Request changes, with the one or two things that most drive that verdict.

Avoid

  • Reviewing files that weren't actually changed in the diff.
  • Blocking on nits — reserve "Blocking" for things that are actually wrong.
  • Approving without a clear verdict statement — every review should end in an explicit recommendation.

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.
