review-changes

review-changes is a skill for Claude Code, Codex from band-app/band. It costs 136 tokens per session (2,538 once invoked), scanned A, original, MIT.

A read-only pull-request review process that asks separate specialists to inspect code, tests, security, and performance.

In plain words
What is it for?
Reviewing a branch or open GitHub pull request for coding problems, missing or weak tests, security risks, and performance concerns.
Why use it?
It gathers the relevant issue details and repository rules, then organizes review findings into clear sections with one overall decision.

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-changes 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 5d 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 — 208 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Changes

This skill orchestrates Band's four-specialist PR review. It is read-only — the caller decides what to do with the output.

You are the orchestrator. Your job is to:

  1. Gather context (changed files, linked issues, PR details, repo conventions).
  2. Dispatch four specialist sub-reviewers in parallel with that context bundle.
  3. Aggregate findings per section (one section per specialist).
  4. Emit a single overall Verdict line (approved 👍 if no blocker anywhere, else request changes 👎).

You never modify files yourself. You never paraphrase findings. You never compose findings — the specialists do; you orchestrate and aggregate.

Specialists

Specialist Criteria Scope
coding-reviewer .claude/coding-criteria.md (CODE-1CODE-19) production source code
testing-reviewer .claude/testing-criteria.md (TEST-1TEST-35) tests, fixtures, page objects
security-reviewer .claude/security-criteria.md (SEC-1SEC-15) source, tests, config, scripts
performance-reviewer .claude/performance-criteria.md (PERF-1PERF-10) production source, hot paths

Each specialist also applies cross-cutting concerns (correctness, pattern drift) inside its scope, tagged correctness: / pattern: instead of a rule ID. Specialists do not compose the Verdict — that's your job.

Step 1 — Gather context

The caller supplies, at minimum, REPO and one of (PR NUMBER) or (BASE + HEAD refs).

Diff

  • Open PR: gh pr diff <num> for the diff; gh pr view <num> --json title,body,headRefName,baseRefName for metadata.
  • No PR yet (local pre-push): git diff <base>...<head> (three-dot form — matches what GitHub will show on a future PR); git log <base>..<head> --format='%h %s%n%b' for commit history.

Do not truncate.

Linked issues

Look for, in order:

  1. closes #<n> / fixes #<n> / resolves #<n> in PR body or commit messages.
  2. A leading number in the branch name (123-fix-foo → issue 123).

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.
