Lists multiple specific concrete actions: 'analyzing error patterns', 'classifying severity', 'applying retry logic', 'suppression budgets', and 'escalation rules'. Uses third person voice correctly.

Clearly answers both what ('Diagnoses and routes failures by analyzing error patterns...') AND when with explicit 'Use when...' clause covering multiple trigger scenarios including error handling, troubleshooting, recovery, and escalation decisions.

Excellent coverage of natural terms users would say: 'errors', 'failures', 'troubleshooting', 'API errors', 'timeouts', 'retry', 'escalate', 'service outages', 'tool dependency failures'. These are terms users naturally use when encountering problems.

Clear niche focused specifically on error handling, failure diagnosis, and recovery logic. The combination of retry logic, suppression budgets, and escalation rules creates a distinct domain unlikely to conflict with general coding or documentation skills.

The skill is lean and efficient, avoiding explanations of concepts Claude already knows. Every section serves a purpose with no padding or unnecessary context about what errors are or how triage works conceptually.

Provides clear tier definitions and concrete examples, but the suppression budget code is pseudocode rather than executable. The workflow steps are clear but lack fully executable implementations for the retry/escalation logic.

Excellent 5-step workflow with explicit validation checkpoint preventing advancement when tier is unknown. Clear feedback loop pattern (detect → gather → classify → execute → report) with explicit escalation conditions and the 'do not advance' guardrail.

Well-organized with clear sections progressing from triggers to tiers to workflow to examples. The note about extracting suppression budget to a separate file for advanced implementations shows appropriate awareness of when to split content.
