Conciseness

The body is efficient and assumes competence — no explanation of what logs or DevTools are — and the code examples earn their tokens. Minor redundancy costs the top score: the "Tell the user: ... → share ... → explain next step" reminder is repeated at the end of all four triage sections after the Reporting Contract already established the pattern.

Actionability

Mostly executable: concrete commands (`vercel logs --follow`, `vercel workflow runs list`, `vercel workflow runs get <run-id>`, `vercel inspect <deployment-url>`, `vercel ls`) and two copy-paste-ready TypeScript logging examples. Not a 5 because the browser-verification section is directional ("Check the Network tab for failed requests") with no concrete command, and "agent-browser" is invoked without usage.

Workflow Clarity

Clear 1→4 triage sequence with explicit checkpoints (the three-part Reporting Contract applied at every step), an explicit Stop Condition section, and feedback loops: "If no logs exist: This is the problem. Add logging before continuing" and "Two consecutive triage steps produce no signal — ... ask the user for more context". This matches anchor 5; the stop rules give error-recovery guidance for the no-signal case.

Progressive Disclosure

Good structure with clear section headers, and the cross-reference to the observability and workflow skills is clearly signaled and one level deep. Not a 5 because the skill is fully monolithic (no bundle files exist), and the ~110-line body — particularly the Add Logging code block and Common Hang Causes list — is borderline content that could be split into a reference file for a leaner overview.

Specificity

The description lists several concrete triage actions — "systematically triages: runtime logs → workflow status → browser verify → deploy/env" — with only the abstract opener "Orchestrated debugging coordinator" being slightly vague. It matches anchor 4 (several specific actions, minor coverage gaps) rather than 5 because the actions are compressed into a single arrow chain and omit reporting/synthesis nuances.

Completeness

Explicitly answers both questions: what — "systematically triages: runtime logs → workflow status → browser verify → deploy/env" — and when — "Triggers from frustration signals (stuck, hung, broken, waiting)". This is equivalent to a 'Use when...' clause with concrete trigger phrases, matching anchor 5; it is not a 4 because the when-clause is explicit rather than implied.

Trigger Term Quality

Natural user phrasings like "stuck, hung, broken, waiting" are exactly what a frustrated user would say. Not a 5 because common variations users actually say — "frozen", "spinning", "timed out", "not loading", "white screen" — appear only in the frontmatter's promptSignals metadata, not in the description text itself.

Distinctiveness Conflict Risk

The debugging-triage coordinator niche with its log→workflow→browser→deploy pipeline is mostly distinct from sibling skills. Minor overlap risk remains with general debugging or observability skills because broad trigger words like "broken" and "waiting" fire on many situations.
