PR Reviewer
A structured pull-request review workflow. Instead of an unstructured "look over this diff" pass, the agent gathers full context, assigns a risk tier, works a fixed correctness/security/tests/performance checklist, and reports findings in a severity-tagged format (blocker / major / minor / nit) with file:line references and concrete fixes.
When to use
- Before merging any non-trivial PR, especially ones touching auth, payments, public APIs, or shared/widely-imported code.
- As a first pass before a human review, to surface the mechanical issues (missing edge cases, weak tests, injection risks) so the human reviewer can focus on design and product judgment.
- On your own PRs before requesting review, to catch obvious issues early.
Not a replacement for architectural/design review — it reviews the diff in front of it, not whether the feature should exist.
Install

bash
npx openagents-cli add openagents/pr-reviewer --runtime claude-code| Runtime | Installed to |

cursor | .cursor/rules/pr-reviewer/ |
codex | .codex/skills/pr-reviewer/ |
generic | .openagents/pr-reviewer/ |
Inputs
| name | type | required | default | description |
|---|---|---|---|---|
pr_ref | string | yes | — | PR number, branch name, or commit range (e.g. 123, feature/x, main..HEAD) |
base_ref | string | no | main | Base branch/ref to diff against |
post_comments | boolean | no | false | Post inline comments to the PR instead of just printing a report |
Example run
> Review PR #482 against main. Don't post comments, just give me the report.
The agent will:
- Run
gh pr diff 482andgh pr view 482 --json title,body,filesfor context. - Classify the PR as High/Medium/Low risk (e.g. High — touches
src/auth/session.ts). - Work the checklist in
rules/review-checklist.md. - Verify new tests actually exercise the changed behavior.
- Print a report using
templates/review-comment.md, ordered blocker → nit.
Files
WORKFLOW.md— the step-by-step procedure (entry point).rules/review-checklist.md— the correctness/security/tests/performance checklist.templates/review-comment.md— output format and severity definitions.
Limitations
- Requires the
ghCLI (or equivalent git/platform access) to fetch PR diffs and metadata; without it, supply a localgit diffrange instead. - Does not run the test suite or a security scanner itself — it reads code, it doesn't execute it. Pair with your CI for dynamic checks (fuzzing, SAST, dependency audits).
- Large diffs (2000+ changed lines) are flagged rather than silently reviewed in full; scope the review to specific files/directories for best results.
post_comments: trueis a side-effectful action — the workflow always confirms the exact comments before posting.
