Conciseness

Lean, table-driven routing content with zero explanation of concepts Claude already knows — every section is actionable triage data. Two intro lines ("These issues can be resolved without escalating to the gateway team:" and "These issues require gateway team involvement:") merely restate their headings and could be trimmed, matching anchor 4's 'minor instances that could be trimmed' rather than anchor 5's 'every token earns its place'.

Actionability

Fully concrete instruction-only guidance: the symptom table pairs each symptom with a specific first check ("spec.address binding", "Listen address (0.0.0.0 vs localhost)", "PolicyBinding → ApiInstance cross-reference") and an exact skill to invoke; escalation criteria are precise ("crash loop, OOMKill", "reproducible after configuration is confirmed valid"); the checklist names concrete artifacts ("flexctl version output", platform list). Per the scoring notes, absence of code is not penalized when guidance is this actionable, and the common cases are all covered.

Workflow Clarity

The diagnostic workflow is clearly sequenced — triage by symptom table, dispatch by available artifact, then escalation decision, then package checklist — with explicit validation gates: escalation is gated on "configuration is confirmed valid by omni-gateway-config", dump analysis is required "before escalating", and the ticket checklist is an explicit pre-flight list. The "Known-good config still failing → live deployed state" row provides an error-recovery path, matching anchor 5's 'checklists + validation steps + feedback loops'.

Progressive Disclosure

The body is a short, well-sectioned overview that delegates all detail via clearly signaled one-level references to sibling skills (omni-gateway-logs, omni-gateway-config, omni-gateway-dump, omni-gateway-install), each referenced with its purpose restated in 'Related Jobs'. No content that belongs in a separate file is inlined, and navigation is trivial — with no bundle files needed, this matches the simple-skill exception for a top score.

Specificity

Lists several specific actions — "Diagnose Omni Gateway errors and failures given any combination of log output, dump files, or symptom descriptions", "decide whether to request debug logs from a customer", "determine whether an issue requires escalation" — but does not enumerate the triage-to-sub-skill routing or escalation-package assembly, so coverage has minor gaps (anchor 4, not 3: well beyond 1-2 actions; not 5: not comprehensive).

Completeness

Clearly answers both: what — "Diagnose Omni Gateway errors and failures given any combination of log output, dump files, or symptom descriptions" — and when — an explicit "Use when the user reports a gateway error (5xx, 4xx, gateway unreachable, policy not applying), has log output to analyze, needs to decide whether to request debug logs… or needs to determine whether an issue requires escalation" with concrete trigger phrases. Matches the anchor-5 example pattern exactly.

Trigger Term Quality

Good natural keyword coverage: "gateway error (5xx, 4xx, gateway unreachable, policy not applying)", "log output to analyze", "debug logs", "escalation". A few natural terms users would say are missing, e.g. specific codes like 502/504, "connection refused", "gateway down", so it falls between "good coverage" (4) and "comprehensive with synonyms" (5).

Distinctiveness Conflict Risk

"Omni Gateway" names a clear niche with product-specific triggers, but the trigger "has log output to analyze" overlaps with the sibling omni-gateway-logs skill's own trigger, creating minor overlap risk with a closely related skill (anchor 4). Not 5: the description does not state it is the family's triage entry point, so both skills could plausibly fire on the same input.
