debug
Structured debugging session — reproduce, isolate, diagnose, and fix. Trigger with an error message or stack trace, "this works in staging but not prod", "something broke after the deploy", or when behavior diverges from expected and the cause isn't obvious.

Output
If Connectors Available
If ~~monitoring is connected:
Pull logs, error rates, and metrics around the time of the issue
Show recent deploys and config changes that may correlate
If ~~source control is connected:
Identify recent commits and PRs that touched affected code paths
Check if the issue correlates with a specific change
If ~~project tracker is connected:
Search for related bug reports or known issues
Create a ticket for the fix once identified
Tips
1. Share error messages exactly — Don't paraphrase. The exact text matters.
2. Mention what changed — Recent deploys, dependency updates, and config changes are top suspects.
3. Include context — "This works in staging but not prod" or "Only affects large payloads" narrows things fast.
