Conciseness

The body is command-dense and assumes domain knowledge (no explanations of SourceLink, P/Invoke, or TFMs), but the artifact-text and identifier-confusion audits are described twice — once in the section prose ("Package Artifact text containment names the Unicode concern kinds found") and again in the follow-on paragraph — which could be consolidated. This matches anchor 4 (efficient with minor trimmable instances); it is not 5 because of that duplication and a few dense sentences that could be tightened.

Actionability

Every section supplies copy-paste-ready commands with realistic targets, e.g. 'dnx dotnet-inspect -y -- package Microsoft.Extensions.AI -S Signals' and 'dnx dotnet-inspect -y -- library System.Text.Json -D @SourceLink --effective', covering package and library paths, rollup and focused sections. Fully executable examples covering the common cases matches anchor 5; there are no gaps that would drop it to 4.

Workflow Clarity

An explicit entry point and escalation path is given up front ("Use the rollup first. For unfamiliar signals, follow explain \"<question>\" and its returned section/resource rather than expanding into every audit"), and sections progress from rollup to focused audits to provenance. It is not 5 because subtle conditionals like "category discovery is structural until --effective is added" state behavior without guidance on when to apply it; the skill is read-only reporting, so no destructive/batch validation cap applies.

Progressive Disclosure

With no bundle files present, the ~85-line body is organized under clear section headers and cleanly signals sibling skills ("see the correctness skill; ... see the sourcelink skill") one level deep. This matches anchor 4 (good structure with minor organization gaps) rather than 5, since the body exceeds simple-skill territory and detail like the SourceLink sub-section catalog could plausibly live in a separate reference file.

Specificity

"Check NuGet package and .NET library provenance, advisories, compatibility metadata and unsafe/interop declarations; investigate focused audit evidence" names multiple concrete actions within a well-defined domain. This matches the anchor for multiple specific concrete actions with comprehensive coverage; it is not a 4 because the action list spans the full inspection surface (provenance, advisories, compatibility, unsafe/interop, audit evidence) rather than leaving minor gaps.

Completeness

The description clearly answers "what" ("Check NuGet package and .NET library provenance, advisories, compatibility metadata and unsafe/interop declarations; investigate focused audit evidence") but contains no "Use when..." clause or equivalent explicit trigger guidance, which caps completeness at 3 per the judging guidelines. It is not 4 because the "when" is entirely absent rather than merely imprecise.

Trigger Term Quality

"NuGet package", ".NET library", "advisories", "compatibility metadata", and "unsafe/interop" are terms users would naturally say, but common synonyms like "vulnerabilities", "security", or "supply chain" are absent. Good keyword coverage with a few natural terms missing matches anchor 4; it is not 5 because synonym coverage is not comprehensive.

Distinctiveness Conflict Risk

"NuGet package and .NET library provenance ... unsafe/interop declarations" carves out a clear niche with distinct .NET-specific triggers and minimal overlap risk with generic tooling or document skills. It clearly matches the anchor for a distinct niche; it is not 4 because the NuGet/.NET scope leaves little ambiguity about when this skill applies.
