Conciseness

The SMART block ("Specific: Clear definition / Measurable: Quantifiable…"), the Strategic/Tactical/Operational framework table, and generic do's/don'ts ("Don't use 3D charts - They distort perception") restate business and dataviz knowledge Claude already has. The troubleshooting section is dense and earns its tokens, so the body is mostly efficient with some removable padding — anchor 3 rather than 2, which would require noticeably verbose throughout.

Actionability

Concrete, near-executable guidance: the MRR normalization CASE expression, the DATE_TRUNC cohort fix, the kpi_snapshot refresh job, and the dynamic-threshold function are all real code. Not 5 because the Python snippets have gaps ("SUM(...)" placeholder in refresh_mrr_summary, missing import statistics), so they are not fully copy-paste ready.

Workflow Clarity

There is no sequenced design process — the intended flow (pick framework level, select KPIs, structure hierarchy) is only implicit in the Dashboard Hierarchy tree, and the checklist-style do's/don'ts and troubleshooting entries lack verification checkpoints. Anchor 3 (sequence/checkpoints implicit) fits; not 4+ because no explicit steps are stated for the core design task.

Progressive Disclosure

The body is a concise overview with a single, clearly signaled, one-level-deep reference: "Detailed sections (starting with `## Common KPIs by Department`) live in `references/details.md`. Read that file when the navigation summary above is insufficient." The referenced file exists, matches its description exactly, and contains no nested references — matching the 5 anchor.

Specificity

"Design effective KPI dashboards with metrics selection, visualization best practices, and real-time monitoring patterns" names the domain and several distinct actions (design, metrics selection, visualization, real-time monitoring), but the actions are abstract patterns rather than concrete operations like extract/fill/merge, so it does not reach the comprehensiveness of the 5 anchor.

Completeness

Both parts are explicit: the what ("Design effective KPI dashboards with metrics selection, visualization best practices, and real-time monitoring patterns") and an explicit when clause ("Use this skill when building… designing… creating… or debugging…") with four concrete trigger scenarios. This matches the 5 anchor exactly; it is not 4 because the when-clause is fully explicit rather than improvable.

Trigger Term Quality

Natural phrases users would actually say are comprehensively covered: "executive SaaS metrics dashboard tracking MRR, churn, and LTV/CAC ratios", "operations center with live service health and request throughput", "cohort retention analysis view", and "debugging a dashboard where metrics contradict each other". Trigger terms include concrete metric names and synonyms spanning build, design, and debug intents; no file extensions apply to this domain.

Distinctiveness Conflict Risk

The KPI-dashboard niche is clear and triggers like MRR, churn, LTV/CAC, and cohort retention are distinct, but "visualization best practices" and generic dashboard language carry minor overlap risk with closely related charting/dataviz skills. This sits at anchor 4 (mostly distinct, minor overlap) rather than 5 (minimal conflict risk).
