Conciseness

Lean and free of basic-concept padding, with concrete file paths and tool names throughout; the Known providers/features/activities snapshot blocks add reference tokens that could be trimmed slightly, keeping it just below a 5.

Actionability

Concrete, executable guidance — exact paths like testing/e2e/src/lib/feature-support.ts, named MCP tools, and a precise output path pattern — but the detailed report format and per-dimension steps are delegated to references rather than inline.

Workflow Clarity

A clear 7-step numbered sequence is followed by an explicit 'Verification before finishing' checklist with validation (report non-empty, git status read-only, every real gap has a URL), providing feedback loops for error recovery.

Progressive Disclosure

The body is an overview with three clearly signaled, one-level-deep references (provider-doc-urls.md, audit-checklist.md, report-template.md), all of which exist as real files; content is appropriately split and easy to navigate.

Specificity

Lists multiple concrete actions — auditing 'feature parity gaps and outdated model lists', producing 'a dated markdown report', and a read-only constraint naming feature-support.ts and model-meta.ts — with comprehensive, file-level specificity.

Completeness

Clearly states what it does and gives explicit when guidance via the invocation syntax, but the 'when' is command-form rather than natural-language trigger phrases, so it is not a 5.

Trigger Term Quality

Includes the explicit '/gap-analysis <provider|feature <name>|models|--all>' trigger plus domain terms (feature parity, model lists, provider adapters), but lacks natural synonyms a maintainer might say (e.g. 'model diff', 'feature matrix').

Distinctiveness Conflict Risk

Targets a narrow maintainer niche (TanStack AI adapter audit, read-only report) with distinct triggers and minimal overlap with other skills.
