Conciseness

The body is lean and assumes competence: no generic explanations of eventing concepts, each section carries non-obvious project-specific knowledge ('the outbox stores its assembly-qualified name; a rename makes Type.GetType() return null', 'Inbox dedups by {eventId, handlerName}', module Order values). Every token earns its place, matching anchor 5.

Actionability

Gives exact file paths, type signatures, API calls ('await outbox.AddAsync(evt, cancellationToken)'), and the registration line 'builder.Services.AddIntegrationEventHandlers(typeof({Consumer}Module).Assembly)'. However, the code is templated with unresolved placeholders ('SomePayload: "…"', 'TenantId: /* current tenant */'), so it is shaped like executable code with minor gaps — anchor 4, not the fully copy-paste-ready anchor 5.

Workflow Clarity

A clear 3-step sequence (define → publish → handle/register) with a closing checklist containing a validation item ('Build + tests green') and a test-drain instruction ('integration tests drain with OutboxDrain.DrainAsync'). It lacks an explicit validate-and-fix feedback loop (no command for building/tests or error-recovery guidance), so anchor 4 rather than 5; the sequence is far too complete for anchor 3.

Progressive Disclosure

Well-organized sections with one clearly signaled one-level-deep reference ('Full model: .agents/rules/eventing.md'), and no bundle files exist to verify further. Not anchor 5: the skill exceeds 50 lines with the deep material (the 'full model') deferred to an external project path that cannot be verified within the skill bundle, and the dense Gotchas section could be part of that deferred detail — good structure with minor organization gaps, i.e. anchor 4.

Specificity

Quotes two concrete actions — 'Publish a cross-module integration event via the Outbox' and 'handle it idempotently in another module' — each with precise qualifiers covering the publish→consume lifecycle. Not a clean anchor 5 ('multiple specific concrete actions') since registration and contract definition are unstated, and above anchor 3 because the two actions are highly specific rather than generic.

Completeness

Explicitly answers both: what ('Publish a cross-module integration event via the Outbox and handle it idempotently in another module') and when ('Use when one module must react to something that happened in another') with a concrete, natural trigger phrase. Matches the anchor 5 exemplar pattern exactly; anchor 4 would require the 'when' to be less explicit than it is.

Trigger Term Quality

Includes natural phrases a user would say: 'one module must react to something that happened in another', plus 'integration event', 'Outbox', 'cross-module'. Missing common variations such as 'event bus', 'publish a message', or 'notification', so it fits anchor 4 ('good keyword coverage; a few natural terms missing') rather than 5.

Distinctiveness Conflict Risk

Clear niche defined by distinct triggers — 'Outbox', 'integration event', cross-module reactivity — that are unlikely to fire for unrelated skills. Matches anchor 5 ('clear niche with distinct triggers; minimal conflict risk').
