Generate an interactive PR review walkthrough as an HTML page. Fetches PR data via gh API, categorizes files into core vs mechanical changes, adds reviewer annotations, and renders diffs with moved-code detection. Use when the user pastes a GitHub PR URL and asks for a review, walkthrough, or summary, or says "review this PR".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PR Review Canvas
Generate an interactive HTML review of a GitHub PR that reads like a peer walking you through what matters.
## Workflow
### 1. Fetch PR data
Run these `gh api` calls in parallel:
```bash
gh api repos/{owner}/{repo}/pulls/{number} --jq '{title, body, user: .user.login, state, additions, deletions, changed_files, base: .base.ref, head: .head.ref}'
gh api repos/{owner}/{repo}/pulls/{number}/files --paginate --jq '.[] | {filename, status, additions, deletions, patch}'
gh api repos/{owner}/{repo}/pulls/{number}/comments --jq '.[] | {user: .user.login, body, path, line}'
```
### 2. Analyze the PR and write the body HTML
Read the diffs, understand the PR, and write the `<body>` content directly as HTML. You have full creative freedom -- the goal is to explain the PR clearly to a reviewer. Use whatever structure best fits the PR.
**Typical structure** (adapt as needed):
- Header with title, PR number, author, stats
- Summary box explaining what the PR does in plain English
- Core file sections with annotations and diffs
- Mechanical/boilerplate files collapsed by default
- Review checklist at the bottom
**But you can also add:**
…Read the whole file at its exact version.
How to install
mdr add asymmetric-al/core/pr-review-canvas@sha256:58cde712e47d6730The line at the top of this page pins the label git:20261021.3c4a499, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
