Lean and efficient with no padding or explanation of concepts Claude already knows; every section (Guardrails, Workflow, Allowed Language, Output Contract) earns its tokens.

Concrete, specific guidance throughout — a numbered workflow with explicit worksheet fields, a named prerequisite skill to invoke, exact phrases to use/avoid, and a copy-paste output contract. No code is expected for this instruction-only skill, so its absence is not penalized.

A clear 5-step sequence with an explicit gating checkpoint (run prediction-market-risk-review before automation) and an approval gate before execution-capable tooling, satisfying the validation-checkpoint requirement.

A short (under 50 lines), single-purpose skill with no external bundle files, organized into well-signaled sections; per the simple-skills note this merits a 3 without external references.

Lists multiple concrete actions — "inspect venues, underliers, constraints, order prerequisites, and manual execution steps" — rather than vague language, matching the multi-action anchor.

The "what" is clear, but the trigger is given as "Use to inspect..." (capability language) rather than an explicit "Use when..." clause naming user scenarios, so per the guideline completeness is capped at 2.

Includes some natural terms ("prediction-market trade planning worksheet", "venues") but leans on jargon ("Itô or venue workflows", "underliers", "order prerequisites") and misses common user phrasings, so it is not full coverage.

The niche is clearly defined — non-advisory prediction-market trade planning for Itô/venue workflows — with distinct triggers unlikely to fire for unrelated skills.
