ultrawork

A set of instructions that activates a special “ultrawork” mode when a prompt contains “ultrawork” or “ulw.” It tells the coding agent how to approach tasks, test changes, and collect evidence.

In plain words
What is it for?
Use it when working in a project that relies on the ultrawork or ulw prompt directive and its associated task rules.
Why use it?
It gives the agent a defined process for handling tasks that require careful verification and a clear record of what was tested.

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 C, and why

ultrawork scanned grade C with 2 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.

How it starts

The opening of the file, as written. The whole thing — 478 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

Tier triage (classify ONCE at bootstrap; record tier + one-line

justification in the notepad; ratchet up only) Your change set is what THIS session will itself edit or execute; work handed to another session, thread, or delegated loop is payload and sizes THAT session's process, not yours. Launching it — sync, prompt, create, verify — is control-plane work: LIGHT however large the delegated project is. Default is LIGHT. Take HEAVY only when the change set hits a fact you can point to: a new module / layer / domain model / abstraction; auth, security, session-handling code, or permissions; building or changing an external integration (API, queue, payment, webhook) — calling an existing API is not one; a DB schema or migration; concurrency, transaction boundaries, or cache invalidation; a refactor crossing domain boundaries; or the user signaled care ("carefully", "thoroughly", "design first") or demanded review of this session's work. When unsure, take HEAVY. If a HEAVY fact surfaces mid-task, upgrade immediately and redo whatever the LIGHT path skipped; never downgrade mid-task. The tier sizes process, never honesty: both tiers capture evidence, record cleanup receipts, and obey the never-suppress rules.

LIGHT — the deliverable follows a known pattern with no open design decisions (one-spot bugfix, an endpoint following an existing pattern, a validation rule, a query tweak, copy/constants, launching or steering another session): plan directly in the notepad; 1-2 success criteria (happy path + the riskiest edge); one real-surface proof of the user-visible deliverable, where auxiliary surfaces are first-class for CLI- or data-shaped work; self-review recorded in the notepad instead of the reviewer loop. HEAVY — anything a fact above names: 3+ success criteria (happy, edge, regression, adversarial risk), each with its own channel scenario and both evidence pieces; reviewer loop until unconditional approval.

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.

ultrawork is a skill published in the GitHub repository code-yeongyu/lazycodex (3,350 stars, last pushed 23d ago), licensed MIT. It adds 62 tokens to every session and 6,280 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
