A workflow stop command for ending a running Output SDK workflow before it finishes.

In plain words
What is it for?
Use it to terminate an in-progress workflow by its ID after checking for partial changes and dependent systems.
Why use it?
It lets you cancel a workflow that is stuck, no longer needed, or using incorrect input. Stopping can leave earlier side effects in place.

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

output-workflow-stop 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 1mo 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.

Stop Running Workflow

Overview

This skill stops a running workflow execution. The workflow will be marked as TERMINATED and will not complete its remaining steps. Use this carefully as it cannot be undone.

When to Use This Skill

  • Cancelling a workflow that's no longer needed
  • Stopping a workflow that appears stuck
  • Terminating a long-running workflow to free resources
  • Aborting a workflow with incorrect input
  • Emergency stop during unexpected behavior

When NOT to Use This

  • If the workflow is about to complete (let it finish)
  • If you're unsure whether stopping is safe
  • For debugging (use npx output workflow debug instead)
  • If the workflow has side effects that may leave data in an inconsistent state

Instructions

Stop a Workflow

npx output workflow stop <workflowId>

Safety Considerations

Before stopping, consider:

  1. Side effects: Has the workflow made changes that need to be rolled back?
  2. Partial completion: Are there steps that completed with side effects?
  3. Dependencies: Are other workflows or systems waiting on this result?
  4. Recovery: Do you need to restart or clean up after stopping?

Examples

Scenario: Stop a stuck workflow

# Check status - workflow has been running too long
npx output workflow status abc123xyz
# Status: RUNNING (for 2 hours)

# Decide to stop it
npx output workflow stop abc123xyz
# Workflow abc123xyz has been stopped

# Verify it's terminated
npx output workflow status abc123xyz
# Status: TERMINATED

Scenario: Cancel a workflow started with wrong input

# Realized input was wrong immediately after starting
npx output workflow start expensive-job --input '{"wrong": "input"}'
# Workflow ID: job-abc123

# Stop before it processes too much
npx output workflow stop job-abc123

# Start again with correct input
npx output workflow start expensive-job --input '{"correct": "input"}'

Scenario: Stop multiple workflows

# Get list of running workflows
npx output workflow runs list --json | jq '.[] | select(.status == "RUNNING") | .workflowId'

# Stop each one (carefully review first!)
for id in abc123 def456; do
  echo "Stopping $id"
  npx output workflow stop $id
done

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.
