Conciseness

The body is directive and dense with no explanations of concepts Claude already knows, but sentences like the Step 1 approval paragraph and the local-source checkout bullet pack many clauses that could be tightened. Matches 'efficient; minor instances of over-explanation that could be trimmed' rather than the every-token-earns-its-place anchor.

Actionability

Guidance is mostly executable with exact commands (`npm outdated --json --depth=0 > .tmp/dependency-maintenance/outdated.json`, `npx --no-install expo install --check`, `npm install --ignore-scripts`), but there are minor gaps: `validate-mobile-files.js` is named without an invocation path, and the install command omits the package/version operand. Fits the 4 anchor (concrete commands with minor gaps) rather than fully copy-paste ready.

Workflow Clarity

Steps 1-4 plus Finish are explicitly sequenced with telemetry checkpoints, per-package AskUserQuestion approval gates, explicit validation commands after each update, and a feedback loop on failure (restore snapshot, reconcile node_modules, return `BLOCKED`). Not 4: validation checkpoints and error-recovery loops are present at every risky stage, not just most.

Progressive Disclosure

The single-file body is well sectioned by step with one clearly signaled top-level external reference (shared-instructions.md, 'read first'), and there are no nested or buried references. Not 5: at ~80 lines with a long multi-host update-path branch list in Step 1, some detail would sit better in a separate reference file; not 3: references that exist are clear and content placement is otherwise appropriate.

Specificity

The description lists multiple concrete actions — 'Checks the mobile-app plugin first, then updates the native host, other Microsoft packages, and all remaining direct npm packages in order with validation and rollback' — fully covering the skill's behavior with no vague filler, matching the comprehensive-coverage anchor. Not 4: there are no minor gaps; every clause names a concrete action in third person.

Completeness

It explicitly answers both questions: 'Use when a Power Apps mobile project needs dependency updates or an npm audit review' provides concrete trigger phrases, and the ordered action list defines what it does. Not 4: the 'when' clause is already explicit and specific, not something that could be made clearer.

Trigger Term Quality

Natural trigger phrases are present — 'Power Apps mobile project', 'dependency updates', 'npm audit review' — which users would plausibly say, matching the good-coverage anchor. Not 5: it lacks synonym and extension variations such as 'packages', 'upgrade', 'outdated', or 'package.json'.

Distinctiveness Conflict Risk

'Power Apps mobile project' dependency updates is a clear niche with distinct, domain-scoped triggers, so conflict risk with generic npm or document skills is minimal. Not 4: the domain qualifier makes overlap with even closely related generic dependency-update skills unlikely.
