Conciseness

The body is lean and consistently repo-specific (symbol names, module paths, exact commands) with almost no explanation of concepts Claude already knows. It falls short of level 5 because version-pinned statements ('CMP 1.11+', 'CMP 1.12+') sit in the main flow rather than a deprecated/old-patterns section, and section 6 enumerates all eleven MCP tool names where a shorter pointer would do. It is well above level 3 since nothing is padded and nearly every line carries project-specific information.

Actionability

Guidance is fully executable: a copy-paste-ready Kotlin snippet for float formatting, exact commands ('python3 scripts/sort-strings.py', './gradlew :schema-strings:sync', './gradlew :desktopApp:hotRun'), exact file paths, and a decision table mapping scenarios to named functions. This matches 'Fully executable; copy-paste ready code or commands; specific examples cover the common cases'.

Workflow Clarity

The 'Workflow to Add a String' is a clearly sequenced 4-step process including a regeneration command and a validation step, and the schema-strings section explains error feedback (':schema-strings:test' fails on hand-written keys). It stops short of level 5 because the final 'Validate UI presentation' step is vague and there is no explicit fix-and-retry loop; it is above level 3 because validation checkpoints are present rather than absent.

Progressive Disclosure

The single file is well organized into numbered sections with a closing 'Reference Anchors' section of exact paths, and it correctly routes bulk lookup to strings-index.txt rather than inlining strings.xml content. It is not level 5 because the referenced bundle files (strings-index.txt, scripts/sort-strings.py) are not present in any references/ or scripts/ directory, and sections like the MCP tooling guide are dense enough to justify a separate reference file.

Specificity

Lists multiple concrete actions — build shared Compose Multiplatform UI, adaptive layouts on Material 3 Adaptive, add/change composables, add user-facing strings, tablet/desktop/landscape layout work — with comprehensive coverage of the skill's domain. This matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage' and exceeds the 'several specific actions; minor gaps' level 4 anchor.

Completeness

Explicitly answers both: what ('Build shared Compose Multiplatform UI... plus the string and resource rules') and when ('Use this whenever you add or change a composable, add a user-facing string, or work on tablet, desktop or landscape layout'). This is the anchor-5 pattern of clear 'what' plus concrete 'when' triggers; level 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

Natural trigger phrases like 'add or change a composable', 'add a user-facing string', and 'tablet, desktop or landscape layout' match what a developer would actually say, but a few natural terms (resources, dialogs, previews, themes) are missing. Good coverage per the level 4 anchor, short of the synonym-and-extension completeness of level 5.

Distinctiveness Conflict Risk

Scoped to a named project (Meshtastic-Android) and a specific niche (shared CMP UI, Material 3 Adaptive, string/resource rules) with distinct triggers, so conflict risk with other skills is minimal. Clear match to the level 5 anchor 'Clear niche with distinct triggers; minimal conflict risk'.
