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-trace 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 3d 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.

Workflow Trace Analysis

Overview

This skill provides guidance on retrieving and analyzing workflow execution traces using the Output CLI. Traces show the complete execution history including step inputs, outputs, errors, and timing information.

When to Use This Skill

  • You have a workflow ID and need to understand what happened
  • A workflow failed and you need to identify which step failed
  • You need to examine the input/output data at each step
  • You want to understand the execution flow and timing
  • You need to find error messages and stack traces
  • Debugging retry behavior or unexpected results

Instructions

Step 1: Retrieve the Execution Trace

Basic trace (text format, may be truncated):

npx output workflow debug <workflowId>

Full trace (JSON format, recommended for detailed analysis):

npx output workflow debug <workflowId> --json

Tip: Always use --json when you need complete trace data. The text format truncates long values which can hide important debugging information.

Step 2: Analyze the Trace

Follow this checklist when examining a trace:

  1. Identify the failed step: Look for steps with error status or failure indicators
  2. Examine error messages: Find the exact error message and stack trace
  3. Check step inputs: Verify the data passed to the failing step was correct
  4. Check step outputs: Look at outputs from preceding steps
  5. Review retry attempts: Note how many retries occurred and their outcomes
  6. Check timing: Look for unusual delays that might indicate timeouts

Step 3: Use the Temporal UI for Visual Analysis

Open http://localhost:8080 in your browser for a visual workflow inspection:

  1. Search for your workflow by ID
  2. View the event history timeline
  3. Click on individual events to see details
  4. Inspect step inputs and outputs
  5. See retry attempts and timing information
  6. Export trace data if needed

output-workflow-trace is a skill published in the GitHub repository growthxai/output (435 stars, last pushed 3d ago), licensed Apache-2.0. It adds 43 tokens to every session and 1,083 once invoked, about $0.0002 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 2026-09-03.
