Conciseness

The body is dense with project-specific facts (naming tables, tracking-pattern routing, pipeline destinations, key file registry) and contains no explanations of concepts Claude already knows. The only rationale prose (constraint 1's declarative-helper exemption) is non-obvious repository knowledge that earns its tokens, fitting anchor 5's "every token earns its place".

Actionability

Concrete, executable guidance throughout: a copy-paste grep command, exact file paths ("static/app/utils/analytics.tsx", "static/gsApp/utils/rawTrackAnalyticsEvent.tsx"), and a situation-to-pattern routing table that tells the reader exactly which pattern and reference to use. Per the scoring notes, an instruction-heavy skill with this specificity meets the fully-actionable anchor.

Workflow Clarity

Multi-step workflows are explicitly sequenced with validation gates: "NEVER create a new event without checking if one already exists" with numbered search steps, Amplitude-first with grep fallback, an AskUserQuestion confirmation gate ("Do not proceed to instrumentation without explicit confirmation"), and a troubleshooting reference covering error recovery (events not firing, TypeScript errors). This matches anchor 5's explicit-checkpoint and feedback-loop pattern; the work is not destructive or batch, so no cap applies.

Progressive Disclosure

SKILL.md is a genuine overview: four references (amplitude-mcp.md, event-definitions.md, tracking-patterns.md, troubleshooting.md) — all verified to exist — each clearly signaled with when to read it ("Read references/event-definitions.md for step-by-step instructions", the "Open reference" routing column, and the troubleshooting "when:" bullets). References are one level deep and easy to navigate, matching anchor 5 exactly.

Specificity

"Instrument and discover analytics events in Sentry's frontend UI" names the domain, and the description enumerates multiple concrete actions — "adding tracking to buttons, pages, modals, or custom interactions", "defining new analytics events", "searching for existing events", "auditing analytics coverage". Coverage is comprehensive, matching the anchor-5 example's structure rather than the minor-gaps level of 4.

Completeness

It explicitly answers both what ("Instrument and discover analytics events in Sentry's frontend UI") and when ("Use when adding tracking... when defining... when searching... when auditing...") with concrete trigger phrases, structurally matching the anchor-5 example. The 'when' clause is present and specific, so no cap applies.

Trigger Term Quality

The trigger list covers natural phrases users would actually say — "add analytics", "track click", "what events exist for", "how many people", "is anyone clicking", "usage of", "who is using" — including synonyms and question phrasings. No natural variants are missing, so it exceeds the good-coverage anchor at 4.

Distinctiveness Conflict Risk

The Sentry frontend UI analytics-instrumentation scoping gives it a clear niche with distinct triggers, matching anchor 5's "clear niche with distinct triggers; minimal conflict risk". The broad usage-question triggers ("how many users", "usage of") carry only minimal overlap risk because they are anchored to analytics-event scoping.
