Conciseness

The body is dense with product-specific, non-inferable facts (which Flex keys are silently ignored, built-in theme IDs, dark-container requirement) with no generic concept explanations, matching 'efficient; minor instances of over-explanation that could be trimmed'. It does not reach 5 because the 'consult docs before claiming names/props' rule is stated five separate times (sections 3–5, Important Facts, Avoid) and the standalone-Flex no-`theme`-prop warning is repeated in five places (security checkpoint, section 2, section 6, Common Mistakes, Avoid) — intentional emphasis, but trimmable.

Actionability

The Flex theming example is copy-paste ready with validated keys and comments, and every mechanism section carries exact doc URLs to fetch — 'mostly executable guidance; concrete code or commands with minor gaps'. It falls short of 5 because the IQ Chat contrast example uses a '"#..."' placeholder, the Theme-API/token-override examples use '{...}' stub bodies, and the IQ Answer/ACK sections provide no concrete props or variables at all (only doc pointers).

Workflow Clarity

The routing workflow is unambiguous: a surface→mechanism table, then one section per surface, each with its doc URLs. There is an explicit validation checkpoint — the security checklist with 'If ANY checkbox is unchecked, STOP and fix before proceeding' — and error-recovery feedback via Common Mistakes entries giving symptom → why → fix, plus a 'use troubleshooting FIRST' hand-off. This matches 'clear sequence with explicit validation steps; feedback loops for error recovery; checklists for complex processes'; no destructive/batch cap applies.

Progressive Disclosure

Good structure: the overview routes by surface, inlines only the highest-value pitfall details, and defers bulk key tables to a clearly signaled 'Bundled References' section with one-line descriptions of each file; references are one level deep. It does not reach 5 because the bundle file references/lucero-tokens.md exists but is never listed or linked anywhere in the body — one of four reference files is undiscoverable from SKILL.md, a 'minor organization gap'.

Specificity

Multiple concrete mechanisms are named per surface — 'Theme API for dashboards, CSS variables for IQ Answer, IQChatOptions for IQ Chat, Flex runtime theme' — alongside concrete capability nouns ('custom colors, white-labeling, dark/light modes, and per-tenant themes'). This matches the anchor 'lists multiple specific concrete actions; comprehensive coverage' within its domain; it is not the level below because no capability is left at generic 'helps with styling' abstraction.

Completeness

Both questions are answered explicitly: what ('Visual customization and branding for Luzmo surfaces' plus a per-surface mechanism routing map) and when ('Use for custom colors, white-labeling, dark/light modes, and per-tenant themes' plus a concrete 'Triggers on:' phrase list). This matches the anchor 'clearly and explicitly answers both what AND when with concrete trigger phrases'; the when-clause is explicit, so the cap of 3 for a missing 'Use when' clause does not apply.

Trigger Term Quality

An explicit 'Triggers on:' list gives natural user phrases — 'change colors', 'brand styling', 'dark mode', 'white-label', 'custom theme', 'IQ Chat styling', 'ACK theming' — covering synonyms and product-specific variations, with 'dark/light modes' also in the Use-for clause. This is comprehensive natural-term coverage; it does not fall to 4 because the common phrasings users would actually say are present, not merely 'good coverage with natural terms missing'.

Distinctiveness Conflict Risk

The description carves a clear niche (Luzmo visual theming only) and actively disambiguates from sibling skills: 'Not for chart data or slots (use data-visualization) or data security (use multitenancy)'. Triggers include component-specific terms ('IQ Chat styling', 'ACK theming') unlikely to fire for the wrong skill, matching the anchor 'clear niche with distinct triggers; minimal conflict risk'.
