Sentry Spike to Draft Fix PR, Held for Review

When a Sentry issue crosses an event threshold, an agent reads the stack trace, locates the offending code.

What it does

Converts a noisy Sentry error into a concrete, reviewable code change. The agent parses the stack trace, finds the relevant source in the repo, and drafts a targeted patch. It opens the change as a draft pull request so the fix never lands without an engineer reading it.

When to use it

Good for well-scoped, repetitive exceptions (null guards, missing validation, off-by-one) where the fix is mechanical but you still want code review. It turns the on-call engineer's job from writing the patch to approving one.

How it works

  1. 1A Sentry issue alert triggers the flow once an error crosses its event threshold.
  2. 2A logic step filters out muted, ignored, or already-linked issues.
  3. 3The agent reads the stack trace and inspects the matching files via the GitHub API.
  4. 4It drafts a minimal fix and opens a draft pull request describing the root cause.
  5. 5A Slack message links the PR and pings the on-call reviewer.
  6. 6The human reviews and merges; the workflow leaves the merge decision entirely to them.
