Conciseness

The body is lean and sectioned with tight bullet lists, an output template, and discipline rules, assuming Claude's competence; the only mild extra is the opening 《实践论》 blockquote which is borderline decoration rather than padding of known concepts.

Actionability

It provides a copy-paste-ready output template and a concrete falsifiable-hypothesis format ('我的假说是：……。如果成立，应能观察到 ……；如果不成立，会看到 ……'), giving mostly executable guidance with only minor gaps for an instruction-only skill.

Workflow Clarity

The procedure is a clearly sequenced steps 0–4 with an explicit validation checkpoint ('判定：成立 / 不成立 / 部分成立'), a retry feedback loop ('不成立 → 修正假说回到第 1 步'), and a termination gate ('不写终止条件不得开始循环'), matching the top anchor.

Progressive Disclosure

The body is a single self-contained file with clean sections and one clearly signaled one-level-deep reference, but that reference ('原著依据：original-texts.md') does not exist in the bundle (no references/ directory, no original-texts.md present), so navigation does not resolve.

Specificity

Names the domain and several actions ('Test a hypothesis or plan in practice, learn from the result, and iterate in a rising spiral with an explicit stop condition'), but the actions are conceptual/methodological rather than concrete tool-level operations, so coverage is not comprehensive.

Completeness

It explicitly answers both 'what' (practice-cognition loop: test, learn, iterate with stop condition) and 'when' ('Trigger when...') with concrete trigger phrases and an explicit skip clause, matching the top anchor.

Trigger Term Quality

Natural trigger phrases a user would voice are present ('a plan needs validation', 'an attempt failed and must be retried', 'thinking without doing (or doing without thinking)') plus skip conditions ('one-shot outputs, lookup questions'), giving good keyword coverage with only a few synonyms missing.

Distinctiveness Conflict Risk

It carves a clear, unusual niche (dialectical practice-cognition epistemology) with specific triggers and explicit skip guidance, with only minor overlap risk against closely related sibling skills like investigation-first or general debugging retries.
