Conciseness

The body avoids explaining concepts Claude already knows, but the same handoffs (launch-registry, list-growth-designer, newsletter-monetization-planner) are restated across the intro, Scope guard, Skill Contract, Instructions, and Reference Materials, which is genuine padding that could be tightened.

Actionability

As an instruction-only design skill it gives concrete, specific directives — quantified criteria (core-flow completion rate, structured-feedback count, error tolerance vs trailing rate), a 5-10%-per-wave invite pattern, exact memory paths, and explicit registry-events.py propose calls — which is actionable rather than abstract or pseudocode.

Workflow Clarity

An 8-step sequence has explicit checkpoints: step 1 pulls and forbids contradicting the existing record, every threshold is labeled Estimated until validated, a 'Done when' checklist enumerates completion, and the destructive registry write is guarded ('never writes memory/launch-registry/ directly', 'ask before writing').

Progressive Disclosure

No bundle files exist; the body is a well-organized overview (Quick Start, Skill Contract, Data Sources, Instructions, Reference Materials, Next Best Skill) with one-level-deep, clearly signaled links to sibling skills and shared docs and no nested reference chains, meeting the well-organized-sections bar.

Specificity

Lists multiple concrete actions — the waitlist→concept→alpha→beta→GA stage ladder, quantified graduation criteria, cohort-gating/invite-throttling, feedback-loop spec with notify-on-status-change, and referral mechanics (invite codes, anti-abuse) — matching the 'multiple specific concrete actions' anchor.

Completeness

Explicitly answers both what ('produces a waitlist→concept→alpha→beta→GA stage ladder...') and when ('Use when the user asks to...'), satisfying the clear-what-and-explicit-trigger anchor rather than the implied-when level.

Trigger Term Quality

Explicit quoted triggers users would naturally say ('design an early access program', 'set up a waitlist and beta stages', 'define beta graduation criteria') plus a bilingual keyword tail (waitlist/内测阶梯/抢先体验/毕业标准/反馈闭环) give good natural-term coverage.

Distinctiveness Conflict Risk

Explicit negative scope carves out adjacent skills ('Not for waitlist acquisition strategy... use list-growth-designer; not for the canonical stage record — use launch-registry'), giving it a clear niche unlikely to trigger the wrong skill.
