Conciseness

The body is dense and assumes competence — no concept explanations, no library introductions — but the Quick Start blocks substantially duplicate code that reappears in Phase A1/A3 and B3, and Critical Gotchas #1/#3/#9/#11/#13 restate in-mode instructions. These are minor trimmable redundancies rather than real padding, so anchor 4 fits better than 5.

Actionability

Nearly all guidance is copy-paste ready executable Python covering creation, layout, width redistribution, updates, deletes, and failure fallbacks. One minor gap: the Build Quick Start block calls `mp.Workspace()` and uses `dau` without the `import mixpanel_headless as mp` or the query step in that block, so it does not run standalone — anchor 4's 'concrete code with minor gaps'.

Workflow Clarity

Each mode has numbered, explicitly ordered phases with validation checkpoints: B1 validates candidate events ("Never build reports for events with zero volume"), B2 forces a plan before building, M1 requires presenting current state to the user before modifying, B5 is a dedicated verify phase, and B3 includes a try/except fallback for failed reports. The strict operation-ordering checklist in M2 and Gotcha 3 covers the destructive batch case.

Progressive Disclosure

The body is a navigable overview with bulk API detail correctly split into four real, one-level-deep reference files. References are well signaled both at point of need ("See references/dashboard-reference.md Section 3.4", "Choose a template from references/dashboard-templates.md" — both verified to exist) and in an annotated See Also section. This matches the anchor-5 example of a clear overview with well-signaled references.

Specificity

"Full CRUD and analysis for Mixpanel dashboards" is elaborated into concrete actions — "analysis (read + understand existing), creation (new builds), modification (update existing), and explanation (data-driven annotation)" — giving comprehensive, specific coverage of the skill's four capabilities. It exceeds anchor 4 because the parenthetical elaboration closes the coverage gaps that would leave it at 'minor gaps'.

Completeness

Both parts are explicit: the what ("Full CRUD and analysis for Mixpanel dashboards… Covers dashboard analysis, creation, modification, and explanation") and the when ("Use when the user asks to build, create, analyze… or asks about dashboard layout"). The when-clause is maximally explicit, so it does not fit anchor 4's 'could be more specific'.

Trigger Term Quality

Ten natural verb triggers ("build, create, analyze, read, understand, explain, modify, update, enhance, or manage dashboards") plus topic nouns ("dashboard layout, text cards, or report arrangement") give comprehensive synonym coverage; no file extensions apply to this domain.

Distinctiveness Conflict Risk

"Mixpanel dashboards" establishes a clear niche, but the Use-when clause lists generic triggers ("manage dashboards", "dashboard layout") without the Mixpanel qualifier, so a user asking about a Grafana or generic analytics dashboard could trigger this skill. Mostly distinct with minor overlap risk against closely related visualization/dashboard skills, rather than the minimal conflict of anchor 5.
