Review

Review the requested code changes as if you are reviewing another engineer's PR.

User-provided target or constraints (honor these): $ARGUMENTS

Target selection

• If no target is provided, review the current code changes: staged, unstaged, and untracked files.
• If the user provides a base branch, review the changes that would merge into that branch. Find the merge base and inspect the diff from that commit.
• If the user provides a commit SHA, review only the changes introduced by that commit.
• If the user provides a PR number, PR URL, or text like PR#68 feat/headless-mode "feat: add non-interactive prompt mode", assume the GitHub CLI is available. Use gh pr view to inspect PR metadata, resolve the base/head branches, fetch as needed, compute the merge base, and review the PR diff. Do not checkout a different branch unless the user explicitly asks or confirms.
• For PRs, do not assume the head branch exists on origin; it may live on a contributor fork. Prefer gh pr checkout --detach <number> only if checkout is acceptable, or fetch the head repository/ref reported by gh pr view --json headRepository,headRefName into a temporary remote/ref before diffing.
• For a PR scenario such as /review PR#68 feat/headless-mode "feat: add non-interactive prompt mode", use the PR number/title/branch as hints, verify them with gh pr view 68, then review the code changes relative to the PR base branch.

Review rubric

Only report issues the original author would likely fix if they knew about them.

Flag a finding only when:

• it meaningfully affects correctness, security, performance, reliability, or maintainability;
• it is discrete and actionable;
• it appears introduced by the reviewed change;
• you can identify the affected code path or user scenario;
• it is not merely a style preference, nit, or intentional behavior change.

Do not stop at the first issue. Return all qualifying findings. If there are no findings worth fixing, say so clearly.

Investigation guidance

Use repository tools to inspect the actual diff and surrounding code. Prefer precise commands such as:

• git status --short
• git diff --staged
• git diff
• git diff <merge-base>...HEAD
• git show <sha>
• gh pr view <number> --json number,title,body,baseRefName,headRefName,url,author

Read nearby implementation and tests when needed to prove whether a suspected issue is real. Avoid speculative findings.

Priority rubric

Use these severity levels for finding titles:

• [P0] — Drop everything to fix. Blocking release, operations, or major usage. Only use for universal issues that do not depend on assumptions about inputs.
• [P1] — Urgent. Should be addressed in the next cycle.
• [P2] — Normal. Should be fixed eventually.
• [P3] — Low. Nice to have.

Finding format

For each finding, include:

• priority tag in the title: [P0], [P1], [P2], or [P3];
• concise title;
• file path and line range;
• one short paragraph explaining why this is a bug and when it matters;
• confidence score if useful.

Keep line ranges as short as possible and make sure they overlap the reviewed diff when possible.

End with an overall verdict:

• patch is correct if existing code/tests should not break and no blocking issues were found;
• patch is incorrect if the patch has blocking correctness, security, reliability, or maintainability issues that should prevent merging.

Do not mark a patch incorrect for non-blocking issues such as style, formatting, typos, documentation nits, or ordinary [P2]/[P3] follow-ups unless they still indicate the patch should not merge.

Do not fix the code unless the user asks after the review.
