Oncall Investigator

Overview

Investigate a production incident from Slack-first context and converge on the earliest failure point, the most likely single root cause, and the fastest safe customer unblock. Prefer signal over verbosity and evidence over speculation. When the primary input is a Slack incident channel URL, treat posting the final investigation back into Slack as the default completion behavior unless the user explicitly asks for draft-only or no-post mode. Treat the shared SpotDraft skill library at https://github.com/SpotDraft/oncall-investigator-skills/tree/master as a first-class source of debugging workflows.

Inputs

• Accept a Slack incident channel URL as the primary input.
• Derive all investigation context from the channel, linked threads, and corroborating sources.
• Reuse identifiers found in Slack across every other tool.
• Default to posting the completed investigation in the same Slack channel and thread tied to that incident URL.
• If the user explicitly asks not to post, prepare the same report as a draft in the local response instead.
