Lists multiple concrete capabilities: 'Generate professional infographics', '21 layout types and 22 visual styles', 'Analyzes content', 'recommends layout×style combinations', 'generates publication-ready infographics'. These are specific, actionable descriptions.

Clearly answers both 'what' (generate infographics with 21 layouts and 22 styles, analyze content, recommend combinations) and 'when' (explicit 'Use when' clause with specific trigger phrases in multiple languages).

Includes natural trigger terms in both English and Chinese: 'infographic', '信息图', 'visual summary', '可视化', '高密度信息大图'. These cover common variations users would naturally say when requesting this type of content.

Highly distinctive niche focused specifically on infographics with detailed scope (layout types, visual styles). The bilingual trigger terms and specific domain (infographics vs. general charts or visualizations) make it unlikely to conflict with other skills.

The skill is extremely verbose at ~300+ lines. Large sections explain tool resolution logic, preference loading priority chains, backup rules, and image backend selection in exhaustive detail that could be dramatically condensed. The 'User Input Tools' and 'Image Generation Tools' sections alone consume significant tokens on runtime-detection logic Claude could handle with far less instruction. The repeated confirmation policy cross-references and inline caveats add further bloat.

The workflow steps are concrete and well-sequenced with specific file paths, option flags, and output structures. However, there is no executable code anywhere — no actual prompt template example, no sample generation command, no example of what a completed `prompts/infographic.md` looks like. The guidance is specific but relies heavily on external reference files (layouts, styles, base-prompt, templates) that are not provided in the bundle, making it incomplete on its own.

The 7-step workflow is clearly sequenced with explicit validation checkpoints: Step 4 is a hard confirmation gate before generation, backup rules protect existing files at each step, Step 6 includes failure retry logic, and the confirmation policy is thoroughly defined with skip conditions. The workflow handles edge cases (language mismatch, backend resolution, file conflicts) explicitly.

The skill references many external files (21 layout definitions, 22 style definitions, analysis framework, structured content template, base prompt, preferences schema, first-time setup) which is good progressive disclosure in principle. However, no bundle files were provided, so all those references are unverifiable. More critically, the SKILL.md itself is a monolithic wall of text — the image generation tools section, user input tools section, and confirmation policy could easily be split into separate reference files rather than inlined at full length.
