<Purpose> Ultrawork is a parallel execution engine for high-throughput task completion. It is a component, not a standalone persistence or verification mode: it provides parallelism, context discipline, and smart delegation guidance, but not durable goal tracking, Team's tmux worker lifecycle, Ralph's legacy persistence loop, architect sign-off, or long-running completion guarantees. </Purpose>

<Use_When>

  • Multiple independent tasks can run simultaneously
  • User says "ulw", "ultrawork", or explicitly wants parallel execution
  • 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 -- use ultragoal instead
  • Task needs coordinated tmux workers, shared task state, mailbox/dispatch coordination, or long-running parallel execution -- use team instead
  • Task requires a full autonomous pipeline -- use autopilot instead (default loop: deep-interview -> ralplan -> ultragoal, with team only when needed)
  • Task intentionally requires the legacy persistent single-owner completion/verification loop -- use ralph 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 to a single executor
  • 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.
  • Always pass the model parameter explicitly when delegating.
  • Read references/agent-tiers.md before first delegation for agent selection guidance.
  • Auto-delegate researcher 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 pattern: 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>

<Steps> 1. Read agent reference: Load references/agent-tiers.md for tier selection. 2. Context + certainty check:

  • State the task intent in one sentence.
  • List the constraints and unknowns that could invalidate a quick fix.
  • If confidence is low, explore first and narrow the task before editing.

3. Define acceptance criteria before execution:

  • What must be true at the end?
  • Which command or artifact proves it?
  • Which manual QA check is required, if any?

4. Classify the work by dependency shape:

  • Independent tasks -> parallel lanes.
  • Shared-file or prerequisite-heavy tasks -> local execution or staged lanes.

5. Choose self vs delegate deliberately:

  • Work locally when the next step depends on immediate repo context, shared files, or tight iteration.
  • Delegate when the task slice is bounded, independent, and materially improves throughput.

6. Run execution lanes:

  • Direct-tool lane for immediate implementation or verification work.
  • Background evidence lanes for tests, docs, repo analysis, or regression checks.

7. Run dependent tasks sequentially: Wait for prerequisites before launching dependent work. 8. Close with lightweight evidence:

  • Build/typecheck passes when relevant.
  • Affected tests pass.
  • Manual QA notes are recorded when the task needs a human-visible or behavior-level check.
  • No new errors introduced.

</Steps>

<Tool_Usage>

  • Use LOW-tier delegation for simple lookups and bounded evidence gathering.
  • Use STANDARD-tier delegation for standard implementation and regression work.
  • Use THOROUGH-tier delegation for complex analysis, architectural review, or risky multi-file changes.
  • Prefer a direct-tool lane when the immediate next step is blocked on local context.
  • Prefer background evidence lanes when you can learn something useful in parallel with implementation.
  • Use run_in_background: true for package installs, builds, and test suites.
  • Use foreground execution for quick status checks and file operations.

</Tool_Usage>

State Management

Use the CLI-first state surface (omx state ... --json) for ultrawork lifecycle state. If explicit MCP compatibility tools are already available, equivalent omx_state calls are optional compatibility, not the default.

  • On start:

omx state write --input '{"mode":"ultrawork","active":true,"reinforcement_count":1,"started_at":"<now>"}' --json

  • On each reinforcement/loop step:

omx state write --input '{"mode":"ultrawork","reinforcement_count":<current>}' --json

  • On completion:

omx state write --input '{"mode":"ultrawork","active":false}' --json

  • On cancellation/cleanup:

run $cancel (which should call omx state clear --input '{"mode":"ultrawork"}' --json)

<Examples> <Good> Two-track execution with acceptance criteria up front:

Acceptance criteria:
- `npm run build` passes
- `node --test dist/scripts/__tests__/codex-native-hook.test.js` passes
- Manual QA: verify `$ultrawork` activation message still points to the session state file

Direct-tool lane:
- update `skills/ultrawork/SKILL.md`

Background evidence lane:
- use /prompts:test-engineer for this scoped task

Why good: Context is grounded first, acceptance criteria are explicit, and the direct-tool lane runs alongside a bounded evidence lane. </Good>

<Good> Correct use of self-vs-delegate judgment:

Shared-file edit in progress across `src/scripts/codex-native-hook.ts` and its test -> keep implementation local.
Independent regression mapping for keyword-detector coverage -> delegate to a test-engineer lane.

Why good: Shared-file work stays local; independent evidence work fans out. </Good>

<Bad> Parallelizing before the task is grounded:

use /prompts:executor for this scoped task
use /prompts:test-engineer for this scoped task

Why bad: No context snapshot, no pass/fail target, and delegation starts before the work is shaped. </Bad>

<Bad> Claiming success without evidence or manual QA:

Made the changes. Ultrawork should be updated now.

Why bad: No verification output, no acceptance evidence, and no manual QA note when the behavior is user-visible. </Bad> </Examples>

<Escalation_And_Stop_Conditions>

  • When ultrawork is invoked directly, apply lightweight verification only -- build/typecheck passes when relevant, affected tests pass, and manual QA notes are captured when needed.
  • Ultrawork does not own persistence, durable ledgers, architect verification, deslop, full QA, or the full verified-completion promise. Do not claim those guarantees from direct ultrawork alone.
  • Escalate to ultragoal when the work needs durable goal state, story checkpoints, or resume across implementation steps.
  • Escalate to team when the work needs coordinated tmux workers, shared task state, or durable multi-worker lifecycle control.
  • Escalate to explicitly requested ralph only for the supported legacy single-owner persistence/verification fallback.
  • Ralph owns persistence, architect verification, deslop, and the full verified-completion promise only when explicitly selected as the supported legacy fallback; direct ultrawork does not own those guarantees.
  • If a task fails repeatedly across retries, report the issue rather than retrying indefinitely.
  • Escalate to the user when tasks have unclear dependencies, conflicting requirements, or a materially branching acceptance target.

</Escalation_And_Stop_Conditions>

<Final_Checklist>

  • [ ] Task intent and constraints were grounded before editing
  • [ ] Pass/fail acceptance criteria were stated before execution
  • [ ] Parallel lanes were used only for independent work
  • [ ] Build/typecheck passes when relevant
  • [ ] Affected tests pass
  • [ ] Manual QA notes recorded when behavior is user-visible
  • [ ] No new errors introduced
  • [ ] Completion claim stays inside ultrawork's lightweight-verification boundary

Relationship to Other Modes

ultrawork (this skill)
 \-- provides: in-session parallel execution discipline + lightweight evidence

ultragoal (durable goal execution)
 \-- owns: goal ledger, checkpoints, resume across stories, final gate discipline
 \-- may use: team for parallel lanes when a story benefits from coordinated workers

team (tmux coordinated execution)
 \-- owns: worker panes, shared task state, mailbox/dispatch, lifecycle control
 \-- can return: checkpoint-ready evidence to an Ultragoal leader

autopilot (strict autonomous delivery loop)
 \-- default flow: deep-interview -> ralplan -> ultragoal -> code-review -> ultraqa
 \-- may use: team only when an Ultragoal story needs parallel execution

ralph (supported legacy explicit fallback)
 \-- owns: single-owner persistence loop + architect verification when intentionally selected

ecomode (deprecated compatibility-only)
 \-- do not route users there from ultrawork; it is not the current model-selection path

Ultrawork is the parallelism and execution-discipline layer. Ultragoal is the current default durable goal/ledger follow-up. Team is the coordinated tmux parallel runtime, often nested under an Ultragoal story when durable work needs multiple lanes. Autopilot orchestrates the full default lifecycle through deep-interview, ralplan, ultragoal, code-review, and ultraqa. Ralph remains active as an explicit legacy fallback for persistent single-owner verification, but it is not the recommended default durable path. Ecomode is deprecated compatibility-only and should not be advertised as the ultrawork model-selection route. </Advanced>
