Conciseness

Mostly efficient - the Key Facts, output-mode table, and csproj example are lean and earn their tokens - but the Troubleshooting section opens by saying the failures 'are covered in depth in references/troubleshooting.md' and then re-details four of them inline with Symptom/Cause/Fix subsections (~35 lines duplicating the reference file), ending with 'For more, see references/troubleshooting.md' again. This is more than a minor instance of over-explanation, matching the anchor 'mostly efficient but includes some unnecessary explanation or could be tightened' rather than the 'minor instances' of level 4.

Actionability

Fully executable, copy-paste-ready guidance covering the common cases: 'dotnet publish /t:PublishContainer -c Release', a complete minimal csproj XML block, a concrete CI publish command with -p: property flags, named MSBuild properties (ContainerRepository, ContainerImageTags, ContainerArchiveOutputPath), an error code (CONTAINER2008), an env var name, and concrete verification commands. It clearly exceeds level 4 by covering the common local, tarball, CI, and registry cases.

Workflow Clarity

A clear implied sequence exists (choose output mode -> set minimal properties -> publish -> verify) with a dedicated Verification section of concrete commands and Symptom/Cause/Fix troubleshooting as an error-recovery loop. It falls short of level 5 because the sequence is never laid out as explicit ordered steps and validation checkpoints (e.g. verifying the tag before pushing in CI) are implicit rather than explicit; it is above level 3 because checkpoints and recovery paths are present, not absent.

Progressive Disclosure

The body is a well-organized overview with clearly signaled, one-level-deep references - all five references/*.md files cited in the body exist in the bundle and are linked with descriptive context (e.g. 'See [references/property-reference.md] for the full property catalog'). However, the four inline Troubleshooting subsections are content that already lives in references/troubleshooting.md and should be split out entirely, a minor organization gap that keeps this below the 'content appropriately split' bar of level 5.

Specificity

The description names multiple concrete capabilities: 'Publish .NET services as container images with the built-in SDK tooling (dotnet publish /t:PublishContainer, Microsoft.NET.Build.Containers)' plus specific coverage areas 'MSBuild property surface, base-image inference, self-contained and AOT implications, and CI/CD publishing'. This matches the anchor for multiple specific concrete actions with comprehensive coverage, and it is written in third person ('Publish...', 'Covers...').

Completeness

The 'what' is clearly and explicitly answered, but there is no 'Use when...' clause or equivalent explicit trigger guidance anywhere in the description. Per the judging guidelines, a missing 'Use when' clause caps completeness at 3, which is exactly the anchor 'has a clear what but when is missing or only weakly implied'.

Trigger Term Quality

Good keyword coverage: '.NET', 'container images', 'Dockerfile', 'dotnet publish', 'MSBuild', 'base image', 'AOT', 'CI/CD'. However, common natural synonyms a user would say are missing - 'containerize' (the official tutorial's own term), 'dockerize', and 'Docker' beyond the single 'Dockerfile' mention - matching the anchor for good coverage with a few natural terms missing rather than comprehensive synonym coverage.

Distinctiveness Conflict Risk

The description claims a clear niche with distinct triggers: SDK-specific tooling names ('dotnet publish /t:PublishContainer', 'Microsoft.NET.Build.Containers', 'MSBuild property surface') make it very unlikely to fire for a generic Docker/containerization skill. This fits the anchor for a clear niche with minimal conflict risk; the score of 4 would require noticeable overlap with a closely related skill, which is not the case.
