808-regulations-eu-digital-markets-act

Use when reviewing, designing, or modifying Java enterprise systems that may support EU Digital Markets Act gatekeeper-platform concerns, core platform services, interoperability, business-user data access, consent-dependent data combination, ranking, self-preferencing, advertising transparency, or anti-circumvention controls. This should trigger for requests such as Review a Java platform for DMA controls; Design interoperability and business-user data access evidence; Add ranking, consent, preference, or anti-circumvention audit controls; Assess gatekeeper-platform engineering evidence before production release.

Quality

Content

52%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.

The body is well-structured with a sound five-step workflow and a clean one-level-deep reference layout, but it is noticeably redundant — the same control enumerations are restated across four or five sections — and the body itself defers all actionable detail to the referenced files without inline examples or criteria. Cutting the repetition and adding a few concrete gap criteria would raise both conciseness and actionability.

Suggestions

Deduplicate the repeated control enumerations: the Scope bullets, Constraints, Workflow steps 2-4, and 'When to use this skill' section restate nearly identical lists — consolidate them into one canonical checklist and reference it from the workflow.

Move the long domain enumerations (service types, artifact types, owner roles) into the chapters-summary or engineering-examples reference and keep SKILL.md as a lean overview, which would also lift progressive_disclosure to the top anchor.

Add one or two inline concrete criteria (e.g., an example of what a ranking-audit signal gap or a missing consent-withdrawal evidence trail looks like in Java code/config) so the body is actionable on its own, and add an explicit validation step for the generated review report before owner handoff.

DimensionReasoningScore

Conciseness

Long noun-list enumerations repeat across nearly every section — the intro, Scope bullets, Constraints, Workflow steps 2-4, and 'When to use this skill' (which nearly duplicates the frontmatter description), and step 1 re-lists reference files already linked three other times. Several sections are padded restatements rather than mostly-efficient content.

2 / 5

Actionability

Concrete artifacts are named (specific reference paths, report template, Kafka messages, feature flags, audit logs, export jobs) and the report template gives step 5 a defined output, but the body stays at enumeration level with no inline examples, criteria, or snippets showing what a gap or control looks like — the operative detail is entirely deferred to the references.

3 / 5

Workflow Clarity

Five ordered steps with an explicit reading order, a gating checkpoint ('Do not start implementation review until the DMA chapters summary, examples reference, and report template are understood'), and a defined output artifact. Not a 5 because the workflow lacks explicit validation/verification of the produced review report before handoff.

4 / 5

Progressive Disclosure

Three real, one-level-deep, clearly signaled references (all verified to exist on disk) plus a dedicated Reference section. Not a 5 because substantial control enumerations that belong in the references are inlined in the body instead of keeping SKILL.md a lean overview.

Description

83%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 description with an explicit 'Use when' clause, concrete trigger-request examples, and a well-defined Java/DMA niche. Main weakness is minor overlap risk with parallel regulation skills in the same toolkit that share the same template phrasing.

DimensionReasoningScore

Specificity

Names the domain (Java enterprise, DMA gatekeeper-platform) and several concrete actions ('reviewing, designing, or modifying', 'Add ranking, consent, preference, or anti-circumvention audit controls', 'Assess gatekeeper-platform engineering evidence before production release'), but the actions are process-level rather than a comprehensive list of discrete artifact-level capabilities.

4 / 5

Completeness

Explicitly answers 'when' twice ('Use when reviewing, designing, or modifying Java enterprise systems...' and 'This should trigger for requests such as...') and conveys 'what' through concrete verbs; matches the anchor for clear and explicit what AND when with concrete trigger phrases.

5 / 5

Trigger Term Quality

Includes natural terms users would say ('Java platform', 'DMA controls', 'interoperability', 'data access', 'ranking', 'consent', 'audit controls', 'production release') plus an explicit trigger clause ('This should trigger for requests such as...'), but misses a few synonyms such as 'EU regulation compliance review' or 'gatekeeper designation'.

4 / 5

Distinctiveness Conflict Risk

Clear niche with distinct DMA-specific triggers (gatekeeper, self-preferencing, anti-circumvention), but the generic 'Java enterprise systems that may support...' opener is a shared template with sibling regulation skills in the same toolkit, creating minor overlap risk.
