# Adversarial code reviewing

> Use when the call is ship or do not ship, and confidence feels untested.

Performs skeptical, high-signal code reviews that try to break confidence in a change by surfacing grounded, material failure modes. Use when asked for an adversarial review, ship/no-ship assessment, or a review focused on subtle production risks instead of balanced feedback.

## Use it

I want to use the Adversarial code reviewing skill by Lachlan Donald.
This is what it does, in the author's own words: Performs skeptical, high-signal code reviews that try to break confidence in a change by surfacing grounded, material failure modes. Use when asked for an adversarial review, ship/no-ship assessment, or a review focused on subtle production risks instead of balanced feedback.
Download the whole folder at https://github.com/lox/agent-skills/tree/main/adversarial-code-reviewing, SKILL.md and every file beside it, into your skills directory: ~/.claude/skills/adversarial-code-reviewing/ for Claude Code, ~/.agents/skills/adversarial-code-reviewing/ for Codex, ~/.cursor/skills/adversarial-code-reviewing/ for Cursor. Get it from the author's repo, not from startupskills.dev.
Then tell me the path you installed it to and how to invoke it.

Nothing here is vendored: install from the author's repo. This file carries none of the author's file.
