Mostly efficient and information-dense with no concept-explanation Claude already knows, but the Capgemini 'integration friction (37%)' stat is cited three times (Overview, Step 2 A3, Anti-patterns) and the 'refuses to pick a winner / not a recommendation' framing recurs across Overview, Step 3, Step 4, and an Anti-patterns row. Not score 3 because that repetition means not every token earns its place; not score 1 because it is not padded with basic concept explanation.

Concrete, executable procedure for an instruction-only skill: the A3 integration scale 'native (1.0) / API-buildable (0.7) / community-plugin (0.5) / not available (0.0)', the 'Halts on 1' / recommends >=3 candidate gate, the fully-specified Step 3 output document structure, and the 5-step Step 4 hand-off. Not score 2 because the guidance is specific and complete rather than pseudocode or incomplete.

Clear four-step sequence (capture inputs, score seven axes, emit matrix, hand off) with explicit checkpoints: the 'halts with INSUFFICIENT_INPUT' input gate, the 'every score citing its source' verification requirement, and the Anti-patterns table as a failure-mode checklist. Not score 2 because checkpoints are explicit rather than implicit; no fix/retry loop is required since this is a non-destructive analysis skill.

SKILL.md is an overview/procedure that delegates the detailed per-sub-axis rubric to references/scoring-rubric.md and the full worked matrix to references/example-matrix.md - both real, one-level-deep files clearly signaled via markdown links in Step 2 and Step 3. Not score 2 because references are clearly signaled and appropriately split rather than inlined or nested.

Lists multiple concrete actions - 'produces a side-by-side evaluation matrix' and 'scoring each on capability fit, cost model, integration depth, vendor lock-in risk, exit cost, contractual posture, and customer-reference data' - naming seven specific scoring axes and the output artifact. Not score 2 because the action set is comprehensive rather than partial.

Clearly answers both what (produces the seven-axis evaluation matrix) and when via the explicit 'Use for commercial procurement decisions only' trigger clause. Not score 2 because an explicit trigger clause is present, so the missing-trigger cap does not apply.

Good coverage of natural terms a QA manager would say - 'QA tools', 'test-management platforms', 'no-code platforms', 'visual regression', 'vendor', 'procurement' - alongside the brand enumeration. Not score 2 because common natural variations are present, not just jargon.

Clear niche with explicit de-confliction - 'Scoped to commercial procurement' and 'not to choosing an open-source code-first framework on architectural fit' - plus 'refuses to recommend a winner'. Not score 2 because it actively scopes against the sibling skill, making wrong-skill triggering unlikely.
