82%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-crafted, expert-level patterns skill: dense with boundary-specific rules, concrete XML/CLI examples, and a useful symptom→cause diagnostic table, with no filler. The main gaps are minor — a couple of named patterns (incremental Inputs/Outputs, extension-point usage) lack executable examples, and the ~110-line body could shed detail into a one-level-deep reference file to keep SKILL.md a leaner overview.
Suggestions
Add a minimal working target snippet demonstrating correct incremental Inputs/Outputs declarations, since rule 3 requires them but no example is given (actionability).
Show a short example of extending $(BuildDependsOn) versus using BeforeTargets="Build" in the extension-points table (actionability).
Move the detailed evaluation-order semantics and design-time build contracts into a one-level-deep references/ file so SKILL.md stays a lean overview (progressive_disclosure).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is lean and rule-dense: evaluation-order diagram, a minimal CORRECT/WRONG XML pair, compact tables for extension points and symptom→cause mapping, with no padding or explanation of concepts Claude already knows beyond one justifiable framing sentence ("MSBuild operates as a component within the .NET SDK..."). It matches 'Lean and efficient; assumes Claude's competence; every token earns its place'; it is above level 4, where noticeable over-explanation would remain. | 5 / 5 |
Actionability | Mostly executable guidance: copy-paste XML (`<OutputType Condition="'$(OutputType)' == ''">Library</OutputType>`), concrete CLI invocations (`dotnet build --no-restore`, the `/t:Restore;Build` anti-pattern), and real target/property names (`_GetProjectReferenceTargetFrameworkProperties`, `SetTargetPath`/`GetTargetPath`, `SetTargetFramework`). It falls short of level 5 because some named rules lack a runnable example — e.g. incremental build `Inputs`/`Outputs` declarations are required by rule 3 but no sample target is shown, and the extension-points table gives no usage snippet. | 4 / 5 |
Workflow Clarity | The multi-step processes are clearly sequenced — the project-reference protocol (outer dispatch → inner build → GetTargetPath) and the four-step cross-repo coordination protocol ending in "Test end-to-end with the SDK's MSBuild integration tests" — and the multi-targeting test checkpoint is stated. It is not level 5 because there are no explicit error-recovery feedback loops (e.g. what to do when the end-to-end test fails) and the symptom→cause table aids diagnosis without prescribing a verification sequence. It clears level 3, which requires missing or merely implicit checkpoints. | 4 / 5 |
Progressive Disclosure | No bundle files exist (no references/, scripts/, or assets/ directories), so the skill is self-contained with no nested references to get lost in; section headers, tables, and the evaluation-order diagram make navigation easy. It scores 4 rather than 5 because at ~110 body lines the detailed reference material (full evaluation-order semantics, design-time build contracts, the bug table) is approaching the point where a one-level-deep reference file would keep SKILL.md as a leaner overview — the 5-anchor's ideal split is not fully realized; it is well above level 3, where structure would be genuinely disorganized or content clearly misplaced. | 4 / 5 |
