Conciseness

The body is mostly efficient with concrete commands and field paths, but cost figures and gating logic are restated across inline phase headers, the Cost Tracking table, and the Tips section — minor padding that could be trimmed.

Actionability

Concrete curl commands and explicit field-extraction lists make the guidance largely executable, but several JSON request bodies are malformed (stray keys outside the -d JSON object in 1a, 3a, 3b, and 4a), which breaks copy-paste readiness.

Workflow Clarity

The phased sequence and conditional gates are clear and error-visibility is strong, but this paid, per-call batch operation has no validation checkpoint before firing expensive fallback calls (Phase 3) and no confirm-cost-with-user step, so the destructive/batch cap applies.

Progressive Disclosure

With no bundle files, the skill is a single well-organized SKILL.md with clear section headers and an example; per the simple/no-external-references guideline, well-organized single-file structure earns the top score.

Specificity

Lists several concrete actions — 'Takes an email (+ optional name) and returns person + company data by cross-referencing cheap APIs first, using expensive AI agents only as fallback' plus 'confidence scoring and full error visibility' — with only minor coverage gaps; not quite the comprehensive multi-action list of a 5.

Completeness

It clearly answers 'what does this do' but has no 'Use when...' clause or equivalent explicit trigger guidance, which the rubric caps at 3.

Trigger Term Quality

Natural terms like 'lead enrichment', 'email', and 'person + company data' are present and would match user requests, but a few common GTM phrasings (e.g. 'enrich this lead', 'look up this email') are not surfaced.

Distinctiveness Conflict Risk

The 'Multi-provider waterfall lead enrichment' niche with cost/confidence framing is mostly distinct from other skills, with only minor overlap risk against generic enrichment skills.
