review

A senior-level pull-request review workflow that checks correctness, security, unnecessary complexity, and project-specific requirements.

In plain words
What is it for?
Use it to review a pull request, run correctness and security reviews, inspect the change against its specification, and verify each review phase before continuing.
Why use it?
It adds structured verification checkpoints and stops work when a required check fails, while reporting non-blocking gaps for correction.

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 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 3d 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 — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kit Preamble — review

Kit Script Root

Kit root: ${CLAUDE_PLUGIN_ROOT}

  • Absolute path above → plugin install (substituted at load time; no project scripts/ dir): prefix every kit script command with it, e.g. bash <kit-root>/scripts/checkpoint.sh …. Absolute paths also work from worktrees.
  • Literal ${…} placeholder above → standalone layout: run commands as written.

Project Context Detection

Run these checks silently at the start. Use results to adapt behavior:

  • [ -f issues.md ] — if true, this project uses the sprint system. Respect issue numbering and STATUS.md.
  • [ -f docs/sprint_state.md ] — if true and Status shows running, a sprint is active. Be aware of parallel work in worktrees.
  • [ -f docs/prd_digest.md ] — if true, read it for quick project context before starting.

Kit Rules

  • Verify gh auth status before any GitHub operation.

Checkpoint Verification Pattern

Every phase has a checkpoint. Run the verification command and check the exit code.

  • Exit non-zero (blocking gate): STOP immediately, report failure, do NOT proceed.
  • Exit 0 with an ADVISORY: line (advisory gate): report the gap, self-correct, continue. Standard prefix:
bash scripts/checkpoint.sh

Append --skill <name> --phase <phase> --issue <ID> for the specific check. checkpoint.sh resolves the main repo root internally, so the command stays a single prefix-matchable form (safe to allowlist as Bash(bash scripts/checkpoint.sh *)).

Worktree Setup Pattern

Pipeline skills operate in git worktrees to isolate changes from main.

  • Create + freeze: WT="$(bash scripts/wt_setup.sh <branch>)" — creates the worktree via scripts/worktree.sh create and writes .claude-kit/freeze-dir.txt inside it in a single step.
  • Resolve main root: bash scripts/worktree.sh root
  • Remove safely: bash scripts/wt_cleanup.sh <branch> — cd's to main root inside a subshell, then removes the worktree (never leaves CWD dangling). All file operations happen inside $WT/. Shared files live on main only.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

review is a skill published in the GitHub repository pillip/claude-dev-kit (11 stars, last pushed 17d ago), licensed MIT. It adds 111 tokens to every session and 4,993 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
