SKILL.md

When fixing an unhandled error from the telemetry dashboard, the issue typically contains an error message, a stack trace, hit count, and affected user count.

The invalid data still flows through the system and will cause failures elsewhere.

Read each frame in the stack trace from bottom to top. For each frame, understand:
