Conciseness

The body is dense with genuinely non-obvious regulatory detail, but it repeats itself: the three decisions are stated in the intro and restated in Core Responsibilities, every tool command appears in both Quick Start and Core Responsibilities (and again in Workflows), and the ~60-term Keywords block is SEO-style padding that adds tokens without operational value. This matches the level-3 anchor ('mostly efficient but includes some unnecessary explanation or could be tightened'); it is not level 4 because the triple repetition of commands and the keyword block are clearly trimmable, and not level 2 because the core content is domain-specific rather than explanations of things Claude already knows.

Actionability

Quick Start gives copy-paste-ready commands ('python scripts/ai_system_risk_classifier.py path/to/systems.json') for all three tools, each with a documented no-arg embedded sample, and all three scripts exist in the bundle with real main entry points. Role/Article tables, the Annex IV artifact checklist, and the concrete Output Standards template make guidance executable. It stops short of level 5 because the input JSON schema is never shown in the body — the user must open the scripts or infer the format — leaving minor gaps.

Workflow Clarity

Workflows 1-4 are clearly sequenced with numbered steps, conditional branching ('If high-risk: run planner'), and Workflow 3 is itself an explicit pre-launch validation checklist with per-item confirmations. This matches the level-4 anchor (clear sequence with most checkpoints present, minor validation gaps). It is not level 5 because no workflow includes an explicit fix-and-retry feedback loop (e.g., what to do when classification is disputed or the planner flags missing Annex IV items), and several Workflow 2 steps are unactionable comments ('# 2. Assemble: ...') rather than commands; it is above level 3 because the destructive/batch validation cap does not apply — these are analytical and documentation workflows, and Workflow 3 supplies the verification gate.

Progressive Disclosure

Verified against the actual bundle: all four references/ files and all three scripts/ files referenced in the body exist, each Core Responsibility section ends with a targeted pointer ('See references/eu_ai_act_titles.md for the full Article-by-Article walkthrough'), and a consolidated, annotated References section lists every file with its scope. Reference files cross-link only laterally within the same level (no 2+ level nesting), and deep regulatory detail is correctly split out of the overview. This matches the level-5 anchor (clear overview with well-signaled one-level-deep references, content appropriately split, easy navigation).

Specificity

The description enumerates three concrete, comprehensive decisions with regulatory precision: risk-tier classification ("prohibited (Art. 5), high-risk (Art. 6 + Annex III), limited-risk (Art. 50), or minimal-risk"), the Article 43 conformity route ("Module A internal control vs Module H full QMS + notified body") plus Annex IV documentation, and per-role obligations with deadlines, and states the concrete output property "Cites Articles + Annexes for every output". This matches the level-5 anchor (multiple specific concrete actions, comprehensive coverage); level 4 requires 'minor gaps in coverage' and none are evident.

Completeness

Explicitly answers 'what' (three enumerated Article-level decisions with named deliverables) and 'when' ("Use during AI system intake review, when planning conformity assessment, or when scoping deployer obligations") with concrete trigger phrases, exactly matching the level-5 anchor. It is not level 4 because the 'when' clause is specific and trigger-anchored rather than merely present.

Trigger Term Quality

Includes the dominant natural terms a compliance user would say — "EU AI Act", "Regulation (EU) 2024/1689", "high-risk", "conformity assessment", "deployer obligations" — plus explicit trigger contexts ("Use during AI system intake review, when planning conformity assessment, or when scoping deployer obligations"). It falls short of the level-5 anchor because several natural synonyms users actually say ("AI regulation Europe", "GPAI", "CE marking AI", "notified body" as a standalone query term) are absent, matching the level-4 anchor 'good keyword coverage; a few natural terms missing'.

Distinctiveness Conflict Risk

The skill occupies a clear niche (EU AI Act operational compliance for compliance teams) and actively disambiguates with explicit negative boundaries — "NOT executive AI strategy (see chief-ai-officer-advisor). NOT a legal substitute" — minimizing wrong-skill triggering. This matches the level-5 anchor (clear niche with distinct triggers, minimal conflict risk); level 4 would require some residual overlap risk with closely related skills, which the NOT-clauses already guard against.
