Conciseness

Quotes: 'DbSetFindingConvention — discovers entities from DbSet<T>', 'IReadOnly* → IMutable* → IConvention* → IRuntime*', 'Filter in RuntimeModelConvention.ProcessModelAnnotations if it's a design-time-only annotation'. Every section is dense, repo-specific fact (file paths, class/method names, test locations) with no padding and no explanation of concepts Claude already knows — lean and efficient, matching anchor 5 rather than anchor 4's 'minor instances of over-explanation'.

Actionability

Quotes: the 5-step 'Adding A Configurable Metadata Facet' procedure with exact artifacts ('CSharpRuntimeModelCodeGenerator', 'CSharpSnapshotGenerator'), concrete APIs ('GetFlattenedProperties()', 'AddInverseNavigation'), exact test paths ('test/EFCore.Design.Tests/Migrations/ModelSnapshotSqlServerTest.cs'), and the command 'EF_TEST_REWRITE_BASELINES=1'. Guidance is mostly executable and specific for an instruction-only skill, but minor gaps remain (e.g. 'Update public API baselines' states the step without the how), keeping it just below anchor 5's copy-paste-ready, common-cases-covered bar.

Workflow Clarity

Quotes: the ordered facet and annotation procedures ending in 'Update public API baselines and cover configuration-source precedence, convention dispatch, runtime/compiled model propagation, and snapshot round trips', plus a dedicated Validation checklist ('Model builds without InvalidOperationException during finalization', 'No spurious migration is generated against a project with an existing snapshot'). Sequences are clear with validation checkpoints embedded, matching anchor 4, but there is no explicit error-recovery feedback loop (validate → fix → retry), which anchor 5 requires.

Progressive Disclosure

Quotes: eleven clearly headed sections including a Testing table ('| Convention unit tests | test/EFCore.Tests/Metadata/Conventions/ |') and a Validation checklist. Structure is good and navigable with no bundle files to reference, matching anchor 4's 'good structure; most content is appropriately placed'; it does not reach anchor 5 because all detail lives inline in a 107-line SKILL.md with no one-level-deep references, and sections like 'Relational Model' or 'Migration Snapshot Compatibility' are candidates for split-out reference files.

Specificity

Quotes: 'Implementation details for EF Core model building' plus concrete class names ('ConventionSet, ModelBuilder, IConvention implementations, ModelRuntimeInitializer, RuntimeModel'). The domain is named precisely with concrete technical targets, but the capability is described with no action verbs ('implementation details' is generic), matching anchor 3's 'names domain and 1-2 concrete actions but not comprehensive' rather than anchor 4's list of several specific actions; it is well above anchor 2 ('Processes PDF files') because the class list delimits scope concretely.

Completeness

Quotes: 'Implementation details for EF Core model building' (what) and 'Use when changing ConventionSet, ... or related classes' (when). Both are present and the 'when' clause is explicit with concrete triggers, but the 'what' is stated abstractly ('implementation details') rather than as concrete actions, so it does not clearly match anchor 5's fully explicit what-and-what-for example; it is well above anchor 3 because the 'when' is explicit, not weakly implied.

Trigger Term Quality

Quotes: 'Use when changing ConventionSet, ModelBuilder, IConvention implementations, ModelRuntimeInitializer, RuntimeModel'. These are the exact class names an EF Core developer would naturally mention, giving good keyword coverage, but common variations like 'conventions', 'fluent API', 'metadata', or 'compiled model' are missing, so it falls short of anchor 5's comprehensive synonym/extension coverage.

Distinctiveness Conflict Risk

Quotes: 'EF Core model building' with triggers 'ConventionSet', 'IConvention implementations', 'ModelRuntimeInitializer', 'RuntimeModel'. This is a clear niche with unambiguous, distinctive class-name triggers and minimal conflict risk; the trailing 'or related classes' adds slight breadth but does not realistically cause the wrong skill to trigger.
