output-workflow-trace-file

output-workflow-trace-file is a skill for Claude Code, Codex from growthxai/output. It costs 55 tokens per session (635 once invoked), scanned A, original, Apache-2.0.

A local trace-file renderer that turns the final output of an Output SDK workflow run into readable Markdown.

In plain words
What is it for?
Use it to view the latest local trace, or find a trace by workflow name or run ID.
Why use it?
It saves you from reading large JSON trace files and separates the workflow's result from its internal execution details.

    Output size or generation rate is not bounded. Unbounded output enables denial-of-service through resource exhaustion, log flooding, or context-window stuffing.
    Fix: Set explicit limits on output length, generation count, and rate. Use max_tokens and truncation to prevent unbounded output.

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-file 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Show just the final output of an Output.ai workflow trace — the actual result, rendered as readable markdown.

The argument the user provided is either a workflow name (e.g. context_competitors) or a workflow run ID. If no argument is provided, use the most recent trace across all workflows.

Instructions

  1. Find the trace JSON file:

    • Trace files live in logs/runs/<workflow_name>/ as JSON files
    • Filenames follow the pattern: <timestamp>_<workflow_id>.json
    • If a workflow name is given, find the latest .json file in logs/runs/<workflow_name>/
    • If a run ID is given, search across all logs/runs/*/ folders for a file containing that ID in its filename
    • If no argument, find the most recently modified .json file across all logs/runs/*/ folders
  2. Extract the output from the trace file. You only need output from the JSON root — skip children and input.

    Strategy for large files (trace files can be 10k+ lines):

    • First, try jq '.output' <file> to extract directly — this is the fastest path
    • If jq is not available: read the last 500 lines of the file (the output field is at the root level, near the end of the JSON). Work backwards in chunks if needed
    • Do NOT read the entire file from the top — the children array with step details can be thousands of lines and you don't need any of it
  3. Save a markdown file to tmp/trace_result_<workflow_name>_<id>.md (create the tmp/ directory if it doesn't exist) with:

    Header (brief)

    • One line: workflow name, ID, duration

    Result

    Render output as clean, readable markdown:

    • String fields that contain markdown → render directly
    • Arrays of objects → render each as a sub-section with key fields
    • Arrays of strings → numbered lists
    • Nested objects → sub-sections with key-value pairs
    • URLs → render as links
    • Long text excerpts → render as blockquotes

    The goal is a document you'd want to READ, not debug. Make it look good.

  4. Tell the user the saved file path.

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.
