Conciseness

Mostly efficient tabular presentation, but a substantial portion restates concepts Claude already knows — the CCL Categories 0–9 table, Product Groups A–E, Reasons for Control codes, the Parts structure table, Country Groups, and a 14-row license-exception glance table duplicating references/license-exceptions.md. This matches the anchor 'Mostly efficient but includes some unnecessary explanation or could be tightened'; not 2 because there is no prose padding and the genuinely non-obvious content (2026 regulatory status, decision logic, thresholds) earns its tokens, and not 4 because the volume of already-known reference data inlined is more than minor.

Actionability

Concrete, directly executable guidance dominates: 'Endurance < 3 hours → 9A012.a.1, controlled AT-only', 'Three factors determine license requirement', '25% of the fair market value... 10% for AT-only or EAR99 going to embargoed countries', 'Retain all export-related records for 5 years', plus specific URLs (snap-r.bis.doc.gov, trade.gov/consolidated-screening-list) and section citations throughout. This matches 'Mostly executable guidance; concrete code or commands with minor gaps' — a few directives remain high-level ('Read license conditions carefully', 'Records must be made available to BIS inspectors on request'), so 5's 'specific examples cover the common cases' is not fully met (no end-to-end worked example).

Workflow Clarity

The Steps 1–8 sequence mirrors the real compliance order of review (jurisdiction → classification → license requirement → exceptions → end-user controls → licensing → recordkeeping) with genuine checkpoints: 'When jurisdiction between ITAR and EAR is ambiguous, submit a CJ request', 'Stop the transaction and conduct due diligence' on red flags, and the critical EAR99-not-a-license-exemption warning. This matches 'Clear sequence with most checkpoints present; minor validation gaps'; not 5 because some checkpoints are advisory rather than explicit gates (e.g., no explicit instruction to verify a provisional ECCN against the current e-CFR before finalizing), and not 3 since the sequence is coherent and checkpoints are mostly explicit.

Progressive Disclosure

The body is a genuine overview that defers detail to three real, verified, one-level-deep reference files, clearly signaled via a contents table ('Full conditions, restrictions, and recordkeeping for all 14 license exceptions', etc.) and an inline pointer at Step 4 ('Reference file: references/license-exceptions.md for complete conditions and restrictions on all exceptions'). Verified against the actual bundle: all three referenced paths exist and contain no nested references, matching the anchor 'Clear overview with well-signaled one-level-deep references; content appropriately split; easy navigation'.

Specificity

The description lists many specific concrete actions with comprehensive coverage — 'ECCN classification across all 10 CCL categories', 'EAR99 determination', 'jurisdiction analysis (EAR vs ITAR order of review)', 'license requirement analysis via Country Chart', 'deemed export rules', 'Foreign Direct Product Rule (FDPR), de minimis thresholds', 'SNAP-R license applications, voluntary self-disclosure, civil/criminal penalties, Export Compliance Program (ECP) design'. This matches the anchor 'Lists multiple specific concrete actions; comprehensive coverage'; nothing is vague, so 4 ('minor gaps in coverage') is too low.

Completeness

Both questions are answered explicitly: the what is the extensive capability enumeration, and the when is the explicit trigger clause 'Use for any dual-use export control, CCL classification, or BIS compliance question'. This matches the anchor 'Clearly and explicitly answers both what AND when with concrete trigger phrases'; 4 would apply only if the when-clause were weaker or less concrete.

Trigger Term Quality

Natural trigger terms are comprehensive for this domain: 'dual-use export control', 'CCL classification', 'BIS compliance' in the when-clause, plus ECCN, EAR99, ITAR, Entity List, de minimis, and 'export control' synonyms throughout. This matches the anchor 'Comprehensive coverage of natural terms including synonyms'; score 4 ('a few natural terms missing') would understate the coverage, as users of this skill phrase questions using exactly this jargon.

Distinctiveness Conflict Risk

The description occupies a clear niche (U.S. EAR/BIS dual-use export controls) and even self-distinguishes from the nearest competing skill territory with 'EAR vs ITAR order of review' and 'EAR vs ITAR jurisdiction determination'. Per the anchor 'Clear niche with distinct triggers; minimal conflict risk'; 4 ('minor overlap risk with closely related skills') fits worse since the ITAR boundary is explicitly drawn.
