Conciseness

The R/I/A/E/B structure is tight and each section carries weight (verbatim source quote, distilled heuristics, execution steps with completion criteria, boundaries), with no padding explaining concepts Claude already knows. It is not a 5 because the A2 trigger scenarios and language signals largely duplicate the frontmatter description, and the adjacent-skill distinctions appear twice (A2 与相邻 skill 的区分 and B 容易混淆的邻近方法论) — minor repetition that could be tightened.

Actionability

The E section gives four numbered steps, each with a completion criterion (完成标准) and one stop condition (判停条件: 若选项不等……直接排除差的，不套启发式), plus concrete thresholds like 「住哪/和谁/做什么」类（锁定 ≥5 年）and a 1–2 年调研窗口. As an instruction-only skill the guidance is concrete and executable, but the steps are judgment heuristics without worked examples of applying them to a real choice, keeping it at anchor 4 rather than fully-executable anchor 5.

Workflow Clarity

The four E steps are clearly sequenced with explicit gates: step 1 gates whether the skill applies at all, step 2 gives a default action (答否) with an escape hatch (除非有非常确定的新证据), and step 3 has an explicit stop condition for non-equal options. This is not a destructive/batch operation, so no validation feedback loop is required; the per-step 完成标准 serve as checkpoints with only minor gaps, matching anchor 4 rather than the feedback-loop-rich anchor 5.

Progressive Disclosure

The body (~110 lines) is appropriately inline at this scale with clear, well-signaled section headers and a logical R→I→A→E→B flow; cross-skill pointers (judgment-training, acceptance, hourly-rate-time) are clearly labeled. The one real defect is a dangling reference: 测试通过率: 见 test-results.md points to a file that does not exist in the bundle — a minor navigation gap that holds this at anchor 4 (minor organization gaps) rather than 5.

Specificity

The description names the domain (major life choices: 换工作/买房/搬城/合伙/结婚) and lists the three concrete heuristics the skill delivers (「无法决定就答否」「三个重大决定值得花一两年」「两个均等选择选短期更痛苦的路」). It is a few concrete actions short of comprehensive — the heuristics are principles rather than a full inventory of what the skill does — matching anchor 4 rather than 5.

Completeness

It explicitly answers both questions: 当用户在重大选择上纠结……列了利弊表还是拿不定主意时调用 gives a concrete 'when' with trigger phrases, and 核心理念 plus the three heuristics give a clear 'what', further sharpened by an explicit 不适用于 exclusion clause. This matches the anchor-5 example structure (what + when with concrete trigger phrases).

Trigger Term Quality

An explicit Triggers line covers natural synonyms in both Chinese and English: 纠结/拿不定主意/要不要/该不该/利弊/decision/hesitate/should I. These are exactly the phrases a stuck user would say, and bilingual synonym coverage matches the comprehensive-synonyms anchor; it cannot be the 4 anchor because almost no common phrasing of this need is missing.

Distinctiveness Conflict Risk

The domain (重大人生选择纠结) and the explicit 不适用于 exclusions (日常琐碎选择、信息查询) make it mostly distinct with a clear niche. Minor overlap remains with generic decision-analysis or pros/cons skills, so it fits anchor 4 rather than the minimal-conflict anchor 5.
