Quality

Content

72%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A concise, well-organized instruction-only skill with concrete design guidance and clean structure. Its main weakness is the absence of explicit validation checkpoints in a workflow that touches destructive operations like committed events and projection rebuilds.

Suggestions

Add explicit validation/verification checkpoints to the Instructions workflow — e.g., after building projections, verify read models against expected state before promoting; test event handlers for idempotency before relying on them.

Remove the verbatim duplication of the description as the body's opening line to trim redundant tokens.

Consolidate overlapping advice between the Safety and Best Practices sections (e.g., 'never delete or modify events' appears in both) to reduce repetition.

DimensionReasoningScore

Conciseness

Lean, well-organized bullets without explaining known concepts, but the body opens by duplicating the description verbatim and Best Practices partially repeats Safety/Instructions, leaving minor redundancy to trim.

4 / 5

Actionability

Numbered instructions give concrete design steps (identify aggregate boundaries, design immutable events) appropriate for an instruction-only skill, though lacking concrete examples or templates that would push it to fully executable.

4 / 5

Workflow Clarity

A clear seven-step sequence exists, but the workflow involves destructive/risky operations (committed events, projection rebuilds) with no explicit validation checkpoints in the steps themselves, triggering the destructive-operation cap of 3.

3 / 5

Progressive Disclosure

A short, well-structured skill under 50 lines with clean section headers and no need for external bundle files, meeting the simple-skill exception for full marks.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description that clearly states capabilities and explicit use-when triggers with good natural language. Trigger term coverage is good but could add a few more synonyms.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — event store design, projection building, saga orchestration, eventual consistency — with comprehensive domain coverage matching the score-5 anchor.

5 / 5

Completeness

Explicitly answers both what (mastery of specific patterns) and when ('Use PROACTIVELY for event-sourced systems, audit trails, or temporal queries') with concrete triggers.

5 / 5

Trigger Term Quality

Good natural triggers like 'audit trails' and 'temporal queries', but missing common synonyms/variations a user might say, so just below comprehensive.

4 / 5

Distinctiveness Conflict Risk

Clear niche in event sourcing/CQRS with distinct, specialized triggers and minimal overlap with unrelated skills.
