review-train

review-train is a skill for Claude Code from big-emotion/agent-atelier. It costs 179 tokens per session (3,691 once invoked), scanned A, original, MIT.

A batch code-review workflow for all open GitHub pull requests. A pull request is a proposed code change awaiting review; this workflow reviews each one and adds a structured review and status label.

In plain words
What is it for?
Use it to review a GitHub pull-request queue, check each change across five areas, post one review comment per pull request, and mark each as approved or needing changes.
Why use it?
It removes the need to open and review every pull request one at a time while keeping the work limited to review actions.

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-train 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 10d 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.

How it starts

The opening of the file, as written. The whole thing — 207 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Train

Code-review a whole list of open pull requests in one pass — and only review. Enumerate every open PR, dispatch a team of parallel reviewer sub-agents, post one structured high-detail review comment per PR, and tag each PR with an approved or changes-requested label.

This skill is strictly review-scoped. It never fixes CI, never resolves merge conflicts, never pushes to any branch, never merges, never closes PRs. Its only writes are: one review comment per PR and one label per PR. It still follows a grouped-confirmation model — all analysis is done read-only first, one plan is presented, and it waits for a single explicit confirmation before posting anything.

If the user also wants CI fixes / conflict resolution / merging, that is a different job — point them at the merge-train skill instead. Do not blur the two.

When to Activate

  • User shares a GitHub pull-requests URL and asks to review them (not merge).
  • User says: "review all the open PRs", "code review the PR queue", "do a review pass on the open PRs", "review and label the PRs", "give me a detailed review on every open PR".
  • User invokes /review-train (optionally with a GitHub PRs URL or --dry-run).

If the user asks to merge / fix CI / resolve conflicts, this is the wrong skill — defer to merge-train.

Inputs

  • Primary: a GitHub pull-requests URL. Any of: /pulls, a search query (/pulls?q=...), a label/milestone filter, or a single PR URL. Honor the filter in the URL — only the PRs the URL would list are in scope. A single-PR URL ⇒ review just that one.
  • If no URL is given, default to the current repo's open PRs (gh pr list); confirm the repo if ambiguous.
  • Flags:
    • --dry-run — produce the full plan + the drafted review bodies and stop; never post a comment or label.
    • --reference <comment-url> — a GitHub comment URL whose structure and depth the reviews must match. If omitted, auto-detect (see Phase 0).
    • --no-label — post review comments but do not apply/modify labels.
    • --include-drafts — also review draft PRs (default: drafts are listed but skipped).
    • --concurrency <n> — max parallel reviewer agents (default 4).
    • --ci-timeout <minutes> — per-PR ceiling on how long to wait for CI to reach a definitive state before reviewing (default: 30). Once the ceiling is hit, the PR is reviewed anyway with CI still pending after <timeout> recorded as context.
    • --ci-poll <seconds> — interval between gh pr checks polls while waiting for CI (default: 30).
    • --no-wait-ci — skip the CI-settle wait entirely and review immediately on whatever CI state is current (may be pending). Default off.

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.
