SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Getting a fast second opinion on a code diff without running the full lint, build, and test pipeline is slow when every review requires the complete workflow. This Skill provides a lightweight review path that examines only the diff, preserving context across review iterations. ## Core Features & Use Cases - Diff-Only Review: Sends only the code diff to Codex exec for review, skipping lint and build pre-checks. - Review Loop with Context Preservation: Supports iterative review rounds while keeping prior context available. - Tier-Aware Findings: Inherits the session tier (standard by default); findings below the tier's blocking severity are logged as [NIT_DEFERRED] rather than fixed. - Use Case: After making a small change to a feature branch, trigger a quick review of just the diff to catch obvious issues before committing, without waiting for the full CI-style review. ## Quick Start Ask the assistant to run a fast Codex review of the current diff using the codex-review-fast workflow.

FAQPage Schema
How do I get a quick code review of just my diff?▼

Trigger the fast review variant with keywords like quick review or diff review. It sends only the diff to Codex exec, skipping lint and build pre-checks, and returns findings based on the session tier.

What is the difference between codex-review-fast and the full codex review?▼

The fast variant reviews only the diff with no lint or build pre-checks and uses a single Codex reviewer. The full review runs lint and build first and supports dual reviewers via the --dual flag.

Can I use two reviewers with the fast diff review?▼

No. The fast variant uses Codex alone with no --dual option and no secondary reviewer. For two reviewers, use the branch-level review with the --dual flag instead.

When should I not use the fast diff review?▼

Avoid it when you need lint and build validation, branch-level scope, document review, or a security audit. Use the full review, branch review, document review, or security audit skills for those cases.

What happens to low-severity findings in a fast review?▼

Findings below the session tier's blocking severity are logged as [NIT_DEFERRED] rather than fixed. The review inherits the session tier, which is standard by default.
