output-debug-workflow

output-debug-workflow is a skill for Claude Code from growthxai/output. It costs 41 tokens per session (1,385 once invoked), scanned A, original, Apache-2.0.

A troubleshooting process for Output SDK workflows that fail, hang, return incorrect results, or produce errors. It checks services, gathers execution evidence, examines traces, and guides targeted fixes.

In plain words
What is it for?
Use it to investigate a failing or stuck workflow, verify required services, inspect execution traces, and apply a focused correction.
Why use it?
It turns an unclear workflow failure into a sequence of checks that can identify whether the problem is infrastructure, execution, or the workflow itself. This makes debugging more systematic.

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-debug-workflow scanned grade A with 1 finding 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.

Your task is to systematically debug an Output SDK workflow issue in a local development environment.

The arguments the user provided describe the problem they're experiencing, and may include a specific workflow ID.

Use the todo tool to track your progress through the debugging process.

Debugging Process

Overview

Follow a systematic approach to identify and resolve workflow execution issues: verify infrastructure, gather evidence, analyze traces, and apply targeted fixes.

<pre_flight_check> EXECUTE: Claude Skill: output-meta-pre-flight </pre_flight_check>

<process_flow>

Step 1: Verify Services Running

Before debugging, confirm that all required services are operational. The output-services-check skill provides comprehensive guidance.

<verification_commands>

# Check Docker containers are running
docker ps | grep output

# Verify Output services respond
curl -s http://localhost:3001/health || echo "API not responding"

# Check Temporal UI is accessible
curl -s http://localhost:8080 > /dev/null && echo "Temporal UI accessible" || echo "Temporal UI not accessible"

</verification_commands>

<decision_tree> IF docker_not_running: RUN: docker compose up -d WAIT: for services to start (30-60 seconds) IF output_dev_not_running: RUN: npx output dev WAIT: for services to initialize IF all_services_running: PROCEED: to step 2 </decision_tree>

Expected State:

  • Docker containers for output are running
  • API server responds at http://localhost:3001
  • Temporal UI accessible at http://localhost:8080

Step 2: List Workflow Runs

Identify the failing workflow execution by listing recent runs. The output-workflow-runs-list skill provides detailed filtering guidance.

<list_commands>

# List all recent workflow runs
npx output workflow runs list

# Filter by specific workflow type (if known)
npx output workflow runs list <workflowName>

# Get detailed JSON output for analysis
npx output workflow runs list --json

# Limit results to most recent
npx output workflow runs list --limit 10

</list_commands>

output-debug-workflow is a skill published in the GitHub repository growthxai/output (443 stars, last pushed today), licensed Apache-2.0. It adds 41 tokens to every session and 1,385 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
