Quality

Content

76%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 highly actionable, well-structured conventions skill with excellent concrete examples and clean progressive-disclosure signaling. Its main gaps are the absent referenced bundle files and the lack of explicit validation/feedback steps for the more error-prone operations.

Suggestions

Ship the five referenced files (clickhouse.md, mysql.md, testing.md, migrations.md, permissions.md) alongside SKILL.md, or remove the dead links, so the navigation signaled at the bottom actually resolves.

Add an explicit validation/verification checkpoint for fragile operations (e.g., a lint or compile check after applying naming/SQL rules, or a test-run step) to lift workflow clarity.

Trim the prose in the SQL construction section to a one-line rationale plus the decision table; the multi-paragraph explanation can be tightened without losing the rule.

DimensionReasoningScore

Conciseness

The body is dense and assumes Claude's intelligence (no explaining of Guice/ClickHouse basics), with only minor trimmable prose in the SQL-rationale section keeping it off the lean anchor 5.

4 / 5

Actionability

Copious copy-paste-ready GOOD/BAD Java snippets with concrete annotations (@Builder(toBuilder=true), @RequiredArgsConstructor(onConstructor_=@Inject)), class names, and method calls cover the common cases fully.

5 / 5

Workflow Clarity

This is a conventions reference rather than a sequenced workflow; the SQL decision table gives clear procedural guidance but there are no explicit validation checkpoints or feedback loops, fitting the 'sequence implicit, checkpoints missing' anchor.

3 / 5

Progressive Disclosure

Clear section headers and a well-signaled one-level reference list with one-line descriptions, but the referenced files (clickhouse.md, mysql.md, testing.md, migrations.md, permissions.md) are not present in the bundle, so navigation would break.

Description

87%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 capability and trigger conditions tied to a concrete codebase location. Its only mild weakness is slightly generic action verbs ('services') and a few missing natural synonyms.

DimensionReasoningScore

Specificity

The description lists several concrete actions ('designing APIs, database operations, or services') anchored to the Java/Opik backend domain, with only minor coverage gaps versus the comprehensive anchor 5.

4 / 5

Completeness

It explicitly answers both 'what' ('Java backend patterns for Opik') and 'when' ('Use when working in apps/opik-backend, designing APIs, database operations, or services') with concrete trigger phrases.

5 / 5

Trigger Term Quality

It surfaces good natural triggers including the specific path 'apps/opik-backend' plus 'designing APIs' and 'database operations', though a few common synonyms are missing.

4 / 5

Distinctiveness Conflict Risk

Tied to a named project and a specific directory path, it carves a clear niche with minimal overlap risk against other skills.
