TMDb: Skill for Claude Code

.claude/skills/review-changes/SKILL.md

review-changes is a skill for Claude Code from adamayoung/TMDb. It costs 0 tokens per session (4,013 once invoked), scanned A, original, Apache-2.0.

A pre-pull-request review of the current branch's changes compared with the main branch. It checks correctness, concurrency, design, tests, and API or documentation issues, then returns findings grouped by severity without changing the code.

In plain words
What is it for?
Use it to review Swift code, committed workflow scripts, and other reviewable project changes before opening a pull request. The report is then used by someone else to make fixes and can be run again.
Why use it?
It provides a structured second check before changes are submitted for review. The review process adjusts to the size of the change and independently checks serious findings on larger changes.

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 9d 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.

The opening of the file, as written. The whole thing — 303 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Changes

Produce the pre-PR review of the current branch's changes against main, following the canonical .github/CODE_REVIEW.md. This skill scales the review to the size of the change — a single agent when the diff is small, a parallel fan-out with adversarial verification when it's large — and returns a severity-graded report. It does not edit code; the caller (e.g. /deliver's code-review phase, or you) applies the fixes.

Principles

  1. One source of truth. Every reviewer — single or fanned-out — follows .github/CODE_REVIEW.md: the severity rubric, scope, and the mandatory adversarial re-evaluation. Don't invent criteria.
  2. Scale to the change. Don't pay for a fan-out Workflow on a 60-line diff; don't review a 12-file multi-model change through one over-stretched context.
  3. Findings only. Return the report; the caller fixes (test-first) and may re-invoke to converge.
  4. Adversarial verification cuts noise. On the large path, every Critical/High finding is independently refuted before it's reported — the strongest lever against false positives.

0. Gate — skip if there is no reviewable code

Code review exists to review code — Swift source, plus the committed scripts under .claude/workflows/ (decision infrastructure) and Scripts/ (enforcement infrastructure: check-defaulted-witnesses.py runs from make lint and as its own CI Lint step, so a bug there silently weakens a gate — it shipped as a false green once already, passing on an empty scan). If the diff touches none of them, there is nothing to review — return immediately, don't spawn any reviewer.

git diff --name-only origin/main...HEAD \
  | grep -qE '\.swift$|^\.claude/workflows/|^Scripts/' \
  || echo "no-reviewable-code"

If that prints no-reviewable-code (e.g. a docs-only, config-only, or skills-prose change), stop here and report "No reviewable code — code review skipped." Do not run §1–§3. (JSON fixtures under Tests/**/Resources/ accompany Swift changes; a fixture-only change with no .swift is rare — note it and let the caller decide.)

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.
