Lists multiple specific concrete actions: 'format-controlled research reports', 'evidence tracking', 'citations', 'source governance', 'multi-pass synthesis', 'source-type governance', 'AS_OF freshness checks', 'mandatory counter-review', 'citation registry', and 'circular verification forbidden'.

Clearly answers both 'what' (generate format-controlled research reports with evidence tracking, citations, source governance, multi-pass synthesis) and 'when' (explicit 'This skill should be used when...' clause with specific trigger scenarios and keywords).

Excellent coverage of natural trigger terms in both English and Chinese, including user-facing phrases like 'research this topic', 'write a report on', 'competitive analysis of', '帮我调研一下', '深度研究', '综述报告', plus domain-specific terms like 'literature review', 'market or industry analysis', '技术选型分析', '竞品研究'.

Highly distinctive niche focused on structured research reports with specific features like source governance, citation registry, counter-review, and freshness checks. The bilingual trigger terms and specialized vocabulary make it unlikely to conflict with generic writing or analysis skills.

The skill is extremely verbose at ~400+ lines with significant redundancy. The Enterprise Research workflow is described twice (once in P0 and again as a standalone section), E3-E5 are detailed individually then summarized again as 'E3-E7'. Source governance tables, anti-patterns, and policy explanations are extensive and could be dramatically condensed. Much of this content (what SWOT is, how to classify sources) is knowledge Claude already possesses.

The skill provides structured steps and specific output formats (registry format, status reports, outline format), which is good. However, there is no executable code—the bash snippet for counter-review is pseudocode showing SendMessage calls that aren't real commands. The guidance is detailed but largely procedural description rather than copy-paste executable instructions. The references to external files that aren't provided also reduce actionability.

The P0-P7 pipeline is clearly sequenced with status checkpoints at each phase, which is strong. However, the Enterprise Research workflow (E1-E7) overlaps confusingly with the general P0-P7 pipeline—it's unclear how they interleave. E3-E5 are described in detail then re-summarized as bullet points, creating confusion about the canonical sequence. The dual-track structure (general vs enterprise) lacks a clear decision point for switching between them.

The skill references many external files (subagent_prompt.md, research_notes_format.md, enterprise_analysis_frameworks.md, etc.) with clear tables showing when to load each, which is good progressive disclosure design. However, no bundle files are provided, making these references unverifiable. The main SKILL.md itself is a monolithic wall of text that inlines too much detail (full source governance tables, registry format, information black box handling) that could be in reference files.
