ultrawork

ultrawork is a skill for Claude Code, Codex from mrzhangguoguo/oh-my-workbuddy. It costs 60 tokens per session (2,470 once invoked), scanned A, original, MIT.

A workflow for completing many independent tasks at the same time using multiple coding agents. It grounds the work in the available context, defines acceptance checks, assigns parallel tasks, and gathers evidence before finishing.

In plain words
What is it for?
Use it for parallel execution of independent coding, research, or verification tasks that do not require shared task state or tightly coordinated workers.
Why use it?
It reduces waiting when separate pieces of work can proceed independently while keeping a final check on their results.

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 A, and why

ultrawork scanned grade A with 0 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 12d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 227 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Ported from oh-my-codex ultrawork. OMX runtime conventions ($macro invocation, omx CLI, .omx/ state directory) are replaced with WorkBuddy idioms (Skill tool, Agent tool, task list, .workbuddy/memory).

<Use_When>

  • Multiple independent tasks can run simultaneously.
  • User says "ulw", "ultrawork", or explicitly wants parallel execution.
  • A task benefits from concurrent execution plus lightweight evidence before wrap-up.
  • You need a direct-tool lane plus optional background evidence lanes without entering Team or a durable goal workflow. </Use_When>

<Do_Not_Use_When>

  • Task needs durable goal tracking, ledger checkpoints, or resume across stories — invoke the ultragoal skill instead.
  • Task needs coordinated workers, shared task state, or long-running parallel execution — spawn teammates via the Agent tool (the team pattern) instead.
  • Task requires a full autonomous pipeline — invoke the autopilot skill (default loop: deep-interview -> ralplan -> ultragoal, with Agent-tool teammates only when needed).
  • Task intentionally requires the legacy persistent single-owner completion/verification loop — invoke the ralph skill explicitly; do not present it as the default durable path.
  • There is only one sequential task with no parallelism opportunity — execute directly, use ultragoal for durable tracking, or delegate a single bounded task to an Agent.
  • The request is still in plan-consensus mode — keep planning artifacts in ralplan until execution is explicitly authorized. </Do_Not_Use_When>

<Why_This_Exists> Sequential task execution wastes time when tasks are independent. Ultrawork keeps the execution branch fast while tightening the protocol: gather enough context first, define pass/fail acceptance criteria before editing, decide deliberately between local execution and delegation, and finish with evidence rather than vibes. </Why_This_Exists>

<Execution_Policy>

  • Gather enough context before implementation. Start with the task intent, desired outcome, constraints, likely touchpoints, and any uncertainty that would change the execution path.
  • If uncertainty is still material after a quick repo read, do a focused evidence pass first instead of immediately editing.
  • Define pass/fail acceptance criteria before launching execution lanes. Include the command, artifact, or manual check that will prove success.
  • Prefer direct tool work when the task is small, coupled, or blocked on immediate local context. Delegate only when the work is independent enough to benefit from parallel execution.
  • When useful, run a direct-tool lane and one or more background evidence lanes at the same time. Evidence lanes can cover docs, tests, regression mapping, or bounded repo analysis.
  • Fire independent Agent calls simultaneously — never serialize independent work.
  • Read references/agent-tiers.md before first delegation for agent/role selection guidance.
  • Auto-delegate a researcher Agent when official docs, version-aware framework guidance, best practices, or external dependency behavior materially affect task correctness; treat it as an evidence lane, not a replacement primary workflow.
  • Use run_in_background: true for operations over ~30 seconds (installs, builds, tests).
  • Run quick commands (git status, file reads, simple checks) in the foreground.
  • Apply the shared workflow guidance: outcome-first framing, concise visible updates for speculative/blocked lanes, local overrides for the active workflow branch, evidence-backed validation, explicit stop rules, and continuation of clear safe execution branches instead of restarting or re-asking.
  • If the user says continue, continue the active workflow branch rather than restarting discovery or re-asking settled questions. </Execution_Policy>

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.
