Conciseness

The body is dense and procedural with no explanations of concepts Claude already knows, but the entry-check/state-recovery rules and context-compression rules are each restated three to four times across Step 0, Step 1e, Step 2, and the closing sections. This repetition is more than minor over-explanation, matching the 'mostly efficient but could be tightened' anchor rather than score 4's 'minor instances'.

Actionability

Nearly every step is backed by exact, executable commands ('comet handoff <change-name> design --write', 'comet state complete-design <name> --design-doc "..." --json', 'comet guard <change-name> design --apply'), plus exact file paths, a frontmatter template, and a full brainstorm-summary.md template. It falls short of score 5 because the JSON result fields it relies on (data.designReadiness, data.issues, agent.continuation) are referenced without any sample output or field format.

Workflow Clarity

Steps are clearly sequenced (0 entry check → 1a–1e design loop → 2 create Design Doc → 3 update state → 3a optional compression → exit conditions → auto-transition) with explicit validation checkpoints: the entry verification, the mandatory user confirmation gate in Step 1c, guard-enforced exit conditions, and a failure feedback loop ('失败时处理 data.issues，保留成果并重试同一 complete-design').

Progressive Disclosure

References to comet-classic/reference/*.md files are clearly named, but the skill's own bundle contains no reference files at all, and reference-grade detail — the default and beta handoff pack formats, truncation markers, hash fields, and compression-recovery rules — is inlined directly in SKILL.md. This matches the 'content that should be separate is inline' anchor rather than score 4's 'most content appropriately placed'.

Specificity

The description names the domain ('Classic 技术设计') and two concrete actions ('完成...技术设计并请用户确认'), but does not mention the phase's core artifacts such as the Design Doc, delta spec patches, or handoff pack. It matches the anchor for naming a domain with 1-2 concrete actions that are not comprehensive, rather than the minimal/generic actions of score 2 or the several specific actions of score 4.

Completeness

Both parts are explicitly answered: 'what' ('完成 Classic 技术设计并请用户确认') and 'when' ('在用户调用 /comet-design，或 Classic Runtime 进入 Design 时使用'), with the 'when' being concrete and specific. It falls short of score 5 because the 'what' is terse and omits what the phase actually produces (brainstorming output, Design Doc, spec patches, guard checks).

Trigger Term Quality

Explicit triggers are present ('用户调用 /comet-design', 'Classic Runtime 进入 Design'), and a user of this pipeline would naturally say them. However, coverage stops there — no natural variations or synonyms such as '技术设计', '深度设计', or 'design 阶段' — matching the 'some relevant keywords but missing common variations' anchor rather than the good coverage of score 4.

Distinctiveness Conflict Risk

The description carves out a clear niche — phase 2 of the comet-classic pipeline — with a unique trigger ('/comet-design') and a runtime-phase condition, so generic design requests will not match it and it will not fire in place of other skills. This matches the 'clear niche with distinct triggers; minimal conflict risk' anchor.
