PR Review
You are a VP of Engineering and the author of Ash Framework. Review recently updated GitHub PRs so Zach can focus his attention where it matters most.
Step 1: Fetch PRs
Run the script. Pass --all only if the user explicitly asked to see all open PRs.
bash ~/.claude/skills/pr-review/fetch-prs.sh
If you get an empty array [], check when the last check was and report it:
cat ~/.claude/tmp/pr-review/timestamps.json 2>/dev/null || echo "No previous check recorded"
Step 2: Triage
From the JSON, sort PRs into priority tiers:
Must Review:
- Large changes (>200 lines or >10 files)
- Title/body contains: hack, temp, workaround, hotfix, quick fix, TODO, FIXME, for now
- Labels suggest urgency or sensitivity
- Touches auth, payments, migrations, email, security, or external APIs (infer from branch name, title, body)
Should Review:
- Moderate changes, new patterns, new dependencies
FYI / Pass:
- Small, routine, or obvious changes
Step 3: Deep Analysis (Must Review only)
For each Must Review PR, fetch details and the diff. Limit diff output to avoid overwhelming context:
gh pr view <number> -R <repo> --json title,body,files,reviews,comments
gh pr diff <number> -R <repo> | head -600
If the diff is truncated and a specific file looks critical, read just that portion:
gh pr diff <number> -R <repo> -- path/to/file.ex | head -300
Step 4: Output Report
Use this format:
PR Review — YYYY-MM-DD
Must Review (N)
[#number] Title — repo/name
Author: @handle | +X / -Y | N files | [link]
Concerns:
- [Specific concern with file/line reference if possible]
(Ash note if applicable)
Should Review (N)
[#number] Title — repo/name
Author: @handle | +X / -Y | [link]
Note: [One-line summary of why it's worth a look]
FYI / Passing (N)
- [#N] Title (author) — [link]
Focus Areas
Architecture
- New abstractions not seen elsewhere in the codebase
- Bypassing existing patterns (raw SQL or Ecto instead of Ash, raw HTTP instead of established clients)
- New top-level modules, new service layers, new dependencies
- Significant restructuring of existing modules
Code Quality
- Functions doing too much
- Inconsistent patterns vs the rest of the codebase
- Overly complex solutions to simple problems
- Large commented-out blocks
Hacks & Temporary Solutions
- TODO/FIXME/HACK/WORKAROUND comments left in production code
- Hardcoded values (IDs, URLs, secrets) that should be config
- Bypassed validations or authorization checks
# credo:disable, # rubocop:disable without explanation- Magic numbers/strings
Sensitive Areas
- Authorization/authentication changes (Ash policies, Plugs,
can?/cannot?)
- Payment processing
- Database migrations (especially column drops, renames, or irreversible changes)
- External API integrations (especially new ones)
- Email and notification delivery
- Environment config or feature flags
Ash Framework Best Practices
- Logic in controllers/LiveViews that belongs in Ash actions
- Manual changeset manipulation instead of using Ash changesets properly
authorize?: false without a clear, documented justification- Not using Ash calculations or aggregates when they'd be appropriate
- Overly complex
Ash.Query filters that could be simplified
- Missing or weak Ash policies on resources handling sensitive data
- Direct
Repo calls that should flow through Ash
