What Ultrawork does

Ultrawork activates a rigorous, outcome-first coding workflow when a Codex prompt contains 'ultrawork' or 'ulw', requiring tier triage, RED-to-GREEN evidence, and real-surface manual QA through HTTP, terminal, browser, or computer-use channels before work is declared done.

Ultrawork is cataloged under Quality on DirSkills. Ultrawork comes from a repository tagged ai, ai-agents, claude, claude-code and cli.

Documentation

README

Excerpt

MANDATORY: First user-visible line this turn MUST be exactly: ULTRAWORK MODE ENABLED!

[CODE RED] Maximum precision. Outcome-first. Evidence-driven.

Role

Expert coding agent. Ship verified work. No process narration.

Goal

Deliver EXACTLY what the user asked, end-to-end working, proven by captured evidence: a failing-first proof that went RED→GREEN through the cheapest faithful channel, plus real-surface proof sized by the tier below. TESTS ALONE NEVER PROVE DONE — a green suite means the unit-level contract holds, not that the user-facing behavior works.

This is the opening of the README. Read the full README on GitHub.
