Conciseness

The body is dense with Act-specific operational data (tier table, Article 6(3) carve-outs, per-role obligation matrix, 2025→2027 phasing) that is not general knowledge, so most tokens earn their place. Minor trimmable padding remains: the three "This skill is NOT..." paragraphs duplicate the description's disclaimers, and the ~40-term Keywords section is inline keyword stuffing. Matches anchor 4 (efficient with minor instances that could be trimmed), not 3 since there is no concept-teaching filler.

Actionability

Fully executable, copy-paste-ready commands with embedded samples for every decision ("python scripts/ai_system_risk_classifier.py path/to/systems.json"), plus four numbered workflows and a concrete Output Standards template. Specific runnable guidance covering the common cases matches anchor 5; the only unshown detail is the systems.json input schema, which the embedded-sample invocations cover.

Workflow Clarity

Workflows 1–4 are numbered with goals, durations, and conditional branching ("3. If high-risk: run planner"), and Workflow 3 is an explicit pre-deployment checkpoint list. However, no error-recovery feedback loops exist (e.g., what to do when a classification is disputed or a cross-check fails), so it matches anchor 4 (clear sequence, most checkpoints) rather than anchor 5's explicit feedback loops. Not a destructive/batch operation, so no cap applies.

Progressive Disclosure

Structure is good: sections are well-organized, and references are one level deep and clearly signaled ("See references/eu_ai_act_titles.md for the full Article-by-Article walkthrough" plus a References section with per-file descriptions). However, the bundle provides no references/, scripts/, or assets/ directories, so every cited path is unverifiable, and the keyword dump plus full tier/role tables are inlined in the overview. Anchor 4 (good structure, references mostly clear, minor organization gaps) fits better than anchor 5, which would require a verified, clean one-level-deep bundle.

Specificity

The description enumerates three concrete decisions with full legal specifics: risk-tier classification across four named tiers ("prohibited (Art. 5), high-risk (Art. 6 + Annex III), limited-risk (Art. 50), or minimal-risk"), the "Article 43 conformity assessment route (Module A internal control vs Module H full QMS + notified body) and... Annex IV technical documentation", and per-role obligation scoping for provider/deployer/importer/distributor/authorized representative. Multiple specific concrete actions with comprehensive coverage matches anchor 5; anchor 4 would require minor coverage gaps that are not present.

Completeness

Both questions are explicitly answered: the "what" is the three enumerated Article-level decisions, and the "when" is concrete — "Use during AI system intake review, when planning conformity assessment, or when scoping deployer obligations." This clearly matches anchor 5; it exceeds anchor 4 because the trigger guidance is specific, not merely present.

Trigger Term Quality

Includes natural terms users would say such as "EU AI Act", "high-risk", "conformity assessment", "deployer obligations", and "compliance", but misses common variations and synonyms like "AI regulation Europe", "CE marking", "GPAI", or spelled-out article names that appear only in the body's Keywords section. Good keyword coverage with a few natural terms missing matches anchor 4 rather than the exhaustive synonym coverage of anchor 5.

Distinctiveness Conflict Risk

The skill occupies a clear single-regulation niche (Regulation (EU) 2024/1689) and actively disambiguates from neighbors: "NOT executive AI strategy (see chief-ai-officer-advisor). NOT a legal substitute." Distinct triggers and minimal conflict risk match anchor 5.
