überPrompt

Appearance

uberprompt tail ​

Print recent traces and stream new ones as they arrive.

Usage ​

bash
uberprompt tail

Prints the most recent traces from the traces collection. Then it opens a MongoDB change stream and prints new traces as they arrive.

Output ​

Each trace is printed as a single line with key fields:

$ uberprompt tail

[12:34:01] triage-router v3  model=gpt-5.1  latency=1240ms  tokens=850  ok
[12:34:03] faq-responder v2  model=gpt-5.1  latency=890ms   tokens=620  ok
[12:34:05] escalation-writer v1  model=gpt-5.1  latency=2100ms  tokens=1420  error: timeout
  ⏳ watching for new traces...
[12:35:12] refund-checker v4  model=gpt-5.1  latency=1050ms  tokens=780  ok

Traces without a prompt binding (from OTLP sources that don't use the SDK) show the operation name instead of a prompt name.

How it works ​

  1. Queries the traces collection for recent documents, sorted by ts descending
  2. Prints each trace summary
  3. Opens a change stream on traces with fullDocument: "updateLookup"
  4. Prints each new or updated trace as it arrives
  5. Runs until interrupted (Ctrl+C)

Prerequisites ​

Run uberprompt init first to create the required collections and indexes.

Set MONGODB_URI in your .env file.
