The description names the domain ('algorithmic philosophies', 'computational aesthetic movements') and lists output file types (.md, .html, .js), but the actual actions are vague—'expressed through code' doesn't specify concrete operations like 'generate', 'render', or 'animate'.

The description partially addresses 'what' (output file types and vague domain) but completely lacks any 'when' clause or explicit trigger guidance. Per the rubric, a missing 'Use when...' clause caps completeness at 2, and the 'what' is also weak, so this scores a 1.

The terms 'algorithmic philosophies' and 'computational aesthetic movements' are highly specialized jargon that users would almost never naturally say. There are no common trigger terms like 'generative art', 'creative coding', 'procedural generation', or 'algorithmic art' that users might actually use.

The niche concept of 'algorithmic philosophies' is unusual enough to avoid many conflicts, but the output types (.md, .html, .js) are extremely generic and could overlap with numerous other skills. The domain is distinctive but poorly bounded.

Extremely verbose at ~300+ lines. Repeats the same concepts multiple times (e.g., 'algorithmic philosophy' concept restated dozens of times, craftsmanship emphasis repeated explicitly and meta-instructed to be repeated, template usage instructions repeated across multiple sections). Explains concepts Claude already understands like what p5.js setup/draw does, what parameters are, and basic HTML structure.

Provides some concrete code snippets (seeded randomness, canvas setup, control-group HTML) but much of the guidance is abstract and philosophical rather than executable. The code examples are fragments/templates rather than complete working implementations. The actual algorithm creation is left entirely open-ended with vague guidance like 'let the philosophy guide the implementation.'

The two-step workflow (philosophy creation → p5.js implementation) is clearly sequenced, and Step 0 (read template) is emphasized. However, there are no validation checkpoints - no step to verify the HTML works, no validation that the algorithm matches the philosophy, no error recovery for common issues like CDN failures or canvas rendering problems.

References external files (templates/viewer.html, templates/generator_template.js) appropriately, but the SKILL.md itself is a monolithic wall of text that inlines enormous amounts of detail that could be split into separate reference files. The philosophy examples, HTML structure details, and implementation guidelines could each be their own referenced documents.
