review is a skill for Claude Code, Codex from greglas75/zuvo. It costs 70 tokens per session (23,753 once invoked), scanned A, original, MIT.

A structured workflow for reviewing code changes with several specialized checks, confidence scoring, validation, and optional fixes.

In plain words
What is it for?
Use it to review uncommitted changes, staged changes, commit ranges, or selected files, then report must-fix issues, recommendations, and minor concerns.
Why use it?
It organizes a code review into repeatable checks and produces a prioritized report of problems that need attention.

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 yesterday.

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 — 1,360 lines — stays where its author put it; the contents beside it link to each section on GitHub.

zuvo:review

Triage the diff, audit it through independent lenses, confidence-score every finding, run cross-model adversarial validation, and deliver a verdict. No separate "go" step required -- the review runs end to end.

Mandatory File Loading

PHASE 0 — Bootstrap (always, before reading any input)

  1. ../../shared/includes/codesift-setup.md      -- [READ | MISSING -> STOP]

This is the ONLY file loaded before reading the diff.

PHASE 0.5 — Classify (read diff, determine content type)

After CodeSift setup, read the git diff. Classify content type:

  • prod-only: diff touches production files only (no *.test.*, *.spec.*)
  • test-only: diff touches test files only
  • mixed: diff touches both production and test files

Print: [CLASSIFIED] Diff type: {prod-only|test-only|mixed}

PHASE 1 — Conditional Load (based on diff type)

Include prod-only test-only mixed
../../shared/includes/env-compat.md Full Full Full
../../shared/includes/quality-gates.md CQ1-CQ40 section only* Q1-Q25 section only** Full
../../shared/includes/cross-provider-review.md Full Full Full

* CQ section only: Read from start of file to the ## Q1-Q25 heading. Skip Q section. ** Q section only: Read from ## Q1-Q25: Test Quality Gates heading to end of file. Skip CQ section. *** cq-patterns loading rule: After Step 1 (classify code type), check the "High-Risk Gates by Code Type" table in cq-checklist.md. If the code type has <=10 relevant gates, load cq-patterns-core.md (~500 tok) instead of cq-patterns.md (~8.4K tok).

What ships with it

4 files 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.
