Conciseness

The body avoids explaining known concepts and has no tutorial-style padding, but it repeats the same constraints across sections: 'Non-negotiables' restates rules from 德哥风格, 'Fallback rules' restates 'Mark uncertainty clearly / No fabricated data', and 'Shared publication style', 'Writing style', and 'Goal' overlap substantially. This is 'mostly efficient but could be tightened' rather than the level-4 'minor instances' anchor, since several sections could be merged or deleted outright.

Actionability

As an instruction-only skill, the guidance is fully actionable: exact input file patterns, a source-map table, minimum-verification rules for titles/reversals/scenarios, a mandatory 9-section article structure with layer templates, concrete example titles, openings, and reversals, plus an exact output path and disclaimer string. Specific examples cover the common cases, matching the fully-executable anchor; there is no missing key detail for executing the task.

Workflow Clarity

The sequence is clear and ordered (inputs → source map → external verification → write → validation checklist → save) with explicit validation checkpoints ('Before final output, check...') and genuine feedback loops: 'If only one file exists' branches, 'If write fails → fallback to chat output', and asking the user when the date is ambiguous. This matches the anchor with explicit validation steps, error-recovery loops, and checklists, one level above 'most checkpoints present'.

Progressive Disclosure

No bundle files exist (no references/, scripts/, or assets/), so all 375 lines live in SKILL.md. Sections are well-headed and navigable, but substantial material — the style guide, the article-structure template, and the example library — is inlined where a one-level reference split would fit, and there are no actual references to signal. This sits at 'some structure but could be better organized; content that should be separate is inline', below the level-4 anchor which expects content appropriately split across files.

Specificity

The description lists multiple concrete actions — 'Generate stage-3 high-impact publishable markdown articles', 'first-principles mechanisms', 'counterintuitive "不是A，是B" framing', 'reusable systemic models', 'strict data/logic validation', 'current web verification' — giving comprehensive coverage of what the skill does. This matches the anchor for multiple specific concrete actions with comprehensive coverage, not level 4, which would require minor coverage gaps.

Completeness

It explicitly answers both what ('Generate stage-3 high-impact publishable markdown articles... first-principles mechanisms, counterintuitive framing, reusable systemic models, and strict data/logic validation') and when ('Use when user wants a 公众号爆款 article, final daily finance article, sharp financial commentary, or first-principles macro/market writing based on upstream markdown documents') with concrete trigger phrases. Voice is third-person imperative, so no specificity penalty applies.

Trigger Term Quality

Natural trigger phrases are present — '公众号爆款 article', 'final daily finance article', 'sharp financial commentary', 'first-principles macro/market writing', 'upstream markdown documents' — giving good keyword coverage. A few natural variations users might say (e.g. plain '爆款文章', '德哥风格 article', 'write a viral finance article') are missing, so it falls just below the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

The description occupies a clear niche (stage 3 of a named pipeline, consuming outputs of 'daily-finance and finance-core-analysis'), making it mostly distinct. However, 'final daily finance article' and 'sharp financial commentary' could overlap with the closely related sibling finance skills, which is exactly the 'minor overlap risk with closely related skills' anchor rather than the minimal-conflict anchor.
