What it does

Gives every engineer an on-demand diagnostician inside Slack. Type the command with a service name and the agent investigates on the spot, summarizing what looks wrong and what it would try, without leaving chat.

When to use it

Use it when someone notices something off but no monitor has fired yet, or when you want a quick second opinion during an active incident. It's the fastest path from a hunch to a structured investigation.

How it works

  1. 1An engineer invokes the slash command in Slack with the target service name.
  2. 2The agent queries Datadog for that service's current error, latency, and resource metrics.
  3. 3It pulls the latest commits and deploys for the service from GitHub to see what changed recently.
  4. 4Logic assembles a diagnosis and a short menu of proposed remediation options ranked by likely impact.
  5. 5The agent replies in the same Slack thread with the findings and the options, leaving the decision and execution to the requesting engineer.
