Use when reviewing, auditing, QAing, critiquing, verifying, or assessing any artifact — a spec, code change, diff, PR, research report, skill, prompt, or document. Also use for pre-completion verification ("verify this works", "prove this is done", "evidence before claiming complete"). Trigger phrases include "review this", "audit this", "QA this", "find issues", "find defects", "critique this", "check this for problems", "what's wrong with this", "evaluate this", "run QA", "review the diff", "review the PR", "review my code", "deep QA", "defect audit", "code review", "assess this", "verify this works", "verify before completing", "prove this is done", "is this actually working". The single skill for all quality assurance — adversarial review, pre-completion verification, and evidence gathering. Cross-model critic lanes (GPT/Gemini via OpenAI-compatible endpoint) are enabled by default for blind-spot diversity; disable with --no-cross-model.

From the source SKILL.md

Systematically audit an existing artifact for defects using parallel critic agents across QA dimensions tailored to the artifact type. Unlike deep-design (which designs and iterates) or deep-research (which explores the web), deep-qa takes an artifact as-is and finds what's wrong with it.

What this skill does

Deep Qa is a community-contributed Claude Code skill in the science-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/deep-qa/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when reviewing, auditing, QAing, critiquing, verifying, or assessing any artifact — a spec, code change, diff, PR, research report, skill, prompt, or document. Also use for pre-completion verification ("verify this works", "prove this is done", "evidence before claiming complete").

Who uses this skill

The Deep Qa Claude Code skill is built for researchers, data scientists, academics, and analysts working with complex data and scientific literature. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 70,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
