review-pr

A review workflow for checking a GitHub pull request, a proposed change to a project, and writing findings to REVIEW.md.

In plain words
What is it for?
Use it to review php-src or another GitHub pull request and, after confirmation, post findings as inline comments with the GitHub command-line tool.
Why use it?
It organizes code-review findings against PHP project standards while keeping publication of comments under your control.

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 C, and why

review-pr scanned grade C with 1 finding 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.

Tells the agent never to refusehighAnti-refusal

Suppressing the ability to decline removes a core safety control; a later harmful request then succeeds.

How it starts

The opening of the file, as written. The whole thing — 187 lines — stays where its author put it; the contents beside it link to each section on GitHub.

review-pr

Review a GitHub pull request against php-src coding standards. Produces REVIEW.md in pwd. Optionally posts findings as inline review comments via the gh CLI — only on explicit user confirmation.

Inputs

  1. PR identifier (required) — a number (12345), #12345, or URL (https://github.com/php/php-src/pull/12345). Default repo is php/php-src.
  2. gh CLI — must be authenticated (gh auth status).
  3. $PHP_SRC_DIR — used to read surrounding context for the diff (file content beyond the hunk).

What it produces

  • REVIEW.md in the task directory resolved per _shared/task-dir.md (default $PHP_SRC_DIR/.claude/php-core-dev/pr-<N>/REVIEW.md) — severity-graded findings, same format as review-local.
  • Slug: pr-<N>. Written to .current.
  • Optionally, on user "yes": inline review comments on the PR via gh pr review / gh api.

Workflow

1. Pre-checks

  • gh auth status succeeds. Otherwise stop with Run: gh auth login.
  • $PHP_SRC_DIR is set and looks like php-src.
  • Argument resolves to a PR.

2. Fetch PR metadata + diff

gh pr view <PR-N> --repo php/php-src \
  --json number,title,body,state,baseRefName,headRefName,headRefOid,url,files,author,labels

gh pr diff <PR-N> --repo php/php-src

Record:

  • Title, author, base branch, head branch (baseRefName / headRefName)
  • Head SHA (headRefOid) — needed for posting inline comments
  • File list with status (added / modified / removed / renamed)
  • Total additions / deletions
  • PR URL

If the PR is closed or merged, proceed but note it in the Scope section.

3. Backup existing REVIEW.md

test -f ./REVIEW.md && mv ./REVIEW.md ./REVIEW.md.bak

4. Read surrounding context

For each touched file, read the post-image from $PHP_SRC_DIR if the PR is against the same checked-out branch as the working tree. Otherwise, read via gh:

gh api /repos/php/php-src/contents/<path>?ref=<headRefOid> --jq '.content' | base64 -d

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.
