Conciseness

The body assumes Akka.NET competence and spends its tokens on non-obvious domain facts ('EventStream is LOCAL ONLY', 'Supervision is for CHILDREN', 'Don't inject ILogger<T> into actors') with tight code samples. However, the Section 6 'Common Mistakes Summary' table and the Section 7 'Quick Reference' decision trees substantially restate Sections 1-4, which is more than a trivial amount of recap.

Actionability

Seven of ten sections contain concrete, near-executable C# (DistributedPubSub mediator setup, OneForOneStrategy with decider switch, try-catch ReceiveAsync handler, Props.Create vs resolver.Props<T>, ILoggingAdapter usage). Not anchor 5: several snippets omit field declarations (e.g. _log, _httpClient, ParseFeed in RssFeedPollerActor) and sections 5, 8, and 10 defer 'full code samples' to reference files that are not present in the bundle, leaving those topics without complete detail.

Workflow Clarity

This is a best-practices reference rather than a linear procedure, and its three decision trees ('Need to communicate between actors?', 'Exception occurred in actor?', 'Creating actor Props?') give unambiguous branch-by-condition guidance covering the main decision points. Not anchor 5 because the anchors' validation checkpoints and error-recovery loops have no equivalent here, though the skill involves no destructive or batch operations that would cap the score.

Progressive Disclosure

The body is well sectioned and its references are clearly signaled and only one level deep ('See [work-distribution-patterns.md](work-distribution-patterns.md) for full code samples'), but none of the three referenced files (work-distribution-patterns.md, cluster-local-abstractions.md, async-cancellation-patterns.md) exist in the bundle — the actual bundle contains only SKILL.md. The apparent content split is therefore illusory: navigation leads to dead links and the detailed material is unreachable, which sits between 'references mostly clear, minor gaps' (4) and 'references present but not clearly signaled' (3).

Specificity

Quotes several specific concrete capabilities: 'EventStream vs DistributedPubSub', 'supervision strategies', 'Props vs DependencyResolver', 'cluster/local mode abstractions for testability' — matching anchor 4 (lists several specific actions, minor gaps). Not anchor 5 because the 'best practices including' framing names topics rather than concrete actions and 'error handling' is generic without the try-catch vs supervision distinction the body actually teaches.

Completeness

The 'what' is clear (a list of specific best-practice areas), but there is no 'Use when...' clause or equivalent explicit trigger guidance anywhere in the description, capping this at 3 per the judging guidelines. It matches anchor 3: clear 'what' with 'when' missing.

Trigger Term Quality

Good coverage of natural domain terms a user would say: 'Akka.NET', 'EventStream', 'DistributedPubSub', 'supervision', 'Props', 'DependencyResolver', 'cluster'. Not anchor 5 because the most natural trigger words — 'actor', 'actor system', 'actor model' — never appear, and no synonyms or related terms (e.g. Akka.Hosting, sharding) are included.

Distinctiveness Conflict Risk

Names a clear niche — Akka.NET-specific APIs ('EventStream vs DistributedPubSub', 'Props vs DependencyResolver', 'supervision strategies') — with distinct triggers and minimal overlap risk with any other skill, matching anchor 5.
