Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00020 | $0.05351 |
| Opus 5 | $0.00010 | $0.02676 |
| Sonnet 5 | $0.00004 | $0.01070 |
| Haiku 4.5 | $0.00002 | $0.00535 |
Grade A, and why
ultrawork-plan 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 10d 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.

Ultrawork Plan Command
Standalone interactive planning - use when you want to plan before committing to execution.
This command follows the planning skill protocol (skills/planning/SKILL.md).
Overview
/ultrawork-plan "goal"
↓
Initialize → Exploration → Clarification → Design → Task Breakdown
↓
Output: design.md + tasks/ (ready for /ultrawork-exec)
Delegation Rules (MANDATORY)
The orchestrator MUST delegate exploration to sub-agents. Direct execution is prohibited except for Overview.
| Phase | Delegation | Direct Execution |
|---|---|---|
| Overview Exploration | N/A | ALWAYS via Skill(skill="ultrawork:overview-exploration") |
| Targeted Exploration | ALWAYS via Task(subagent_type="ultrawork:explorer") |
NEVER |
| Planning (non-auto) | N/A | ALWAYS (interactive by design) |
| Planning (auto) | ALWAYS via Task(subagent_type="ultrawork:planner") |
NEVER |
Exception: User explicitly requests direct execution (e.g., "run this directly", "execute without agent").
Interruptibility (Background + Polling)
To allow user interruption during exploration, use background execution with polling.
# Poll pattern for all Task waits
while True:
# Check if session was cancelled
phase = Bash(f'bun "{CLAUDE_PLUGIN_ROOT}/src/scripts/session-get.js" --session ${CLAUDE_SESSION_ID} --field phase')
if phase.output.strip() == "CANCELLED":
return # Exit cleanly
# Non-blocking check
result = TaskOutput(task_id=task_id, block=False, timeout=5000)
if result.status in ["completed", "error"]:
break
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-plan is a command published in the GitHub repository mnthe/hardworker-marketplace (4 stars, last pushed 4mo ago), licensed MIT. It adds 20 tokens to every session and 5,351 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
implement
Execute the implementation plan by processing and executing all tasks defined in tasks.md.
