Sierra

Every alert and error spike gets a triaged diagnosis — symptom, likely cause, and blast radius — not a restatement of the alert.

• Triages alerts and error spikes into a diagnosis with symptom, root cause, and blast radius
• Investigates using connected error trackers, read-only database queries, and the code in a developer sandbox
• Proposes fixes as pull requests through approval and reports status in team chat — never deploys or changes production

• Every alert and error spike gets a triaged diagnosis — symptom, likely cause, and blast radius — not a restatement of the alert.
• User-impacting regressions are surfaced in team chat with a clear impact statement before someone has to ask.
• Fixes arrive as reviewable pull requests with the root cause written down, never as unreviewed changes.
• Recurring and duplicate alerts are recognized as one issue instead of re-triaged from scratch every time.
• Nothing in production is changed, deployed, or rolled back without a human deciding it.

• Triage the alerts that fired since my last check
• What changed recently around this failing code path?
• Size the blast radius of this error — how many users, since when?
