review-pr

review-pr is a command for Claude Code from mcpwright/census-mcp. It costs 26 tokens per session (308 once invoked), scanned A, a copy of review-pr, MIT.

A command that asks a separate code-review agent to inspect the current branch's changes before a pull request. A pull request is a proposed set of changes for review before merging into a project.

In plain words
What is it for?
It helps check the commit range and changed files, launch an adversarial review against a chosen base branch, and report the findings before opening a pull request.
Why use it?
It adds a fresh review of the actual diff, which can reveal issues the author or current agent missed. It does not make fixes automatically.

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

review-pr 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 2d 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.

Origin

This is a copy

100% identical to review-pr — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Run a pre-PR code review of the current branch using the code-reviewer subagent. The point is a review in a fresh context — so do not summarize the diff yourself; let the subagent read the code.

Base ref: $1 (default main if empty).

  1. Sanity-check the range: run git log <base>..HEAD --oneline and git diff --stat <base>...HEAD so you (and I) can see what's in scope. If the branch is main or has no commits over the base, stop and say so.
  2. Launch the code-reviewer subagent (Task tool, subagent_type: code-reviewer). Tell it only the base ref and that it should run git diff <base>...HEAD and read the touched files itself. Do not paste the diff or describe the change — its value is the independent read.
  3. Relay the subagent's report back verbatim under a ## Code review heading.
  4. Do not fix anything yet. Wait for me to decide which findings to address; then I'll have you fold them in before the PR.

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.
