markusdowne/error-triage-ladder

Diagnoses and routes failures by analyzing error patterns, classifying severity, and applying retry logic, suppression budgets, and escalation rules. Use when handling errors, troubleshooting failures, recovering from API errors or timeouts, deciding whether to retry or escalate an issue, or managing service outages and tool dependency failures. Applies to any scenario where a check has failed, evidence of success is missing, or an unresolved error needs a structured response. Includes explicit untrusted-content/prompt-injection guardrails for third-party inputs.
