Names the domain (Cursor IDE projects) and lists some areas (directory structure, rules organization, indexing strategy, team configuration patterns), but these are more like topic areas than concrete actions. It doesn't specify what actions are performed (e.g., 'generates', 'creates', 'recommends').

The 'what' is partially addressed (reference architecture for Cursor IDE projects), and while it lists trigger phrases, it lacks an explicit 'Use when...' clause that describes the situations or user needs that should activate this skill. The 'Triggers on' phrasing is close but reads more like keyword tagging than contextual guidance.

Includes explicit trigger terms like 'cursor architecture', 'cursor project structure', 'cursor best practices', 'cursor file structure', which are reasonable. However, it misses natural variations users might say like 'set up cursor', 'organize cursor project', 'cursor rules', 'cursor config', or '.cursorrules'.

The description is clearly scoped to Cursor IDE project architecture specifically, with distinct trigger terms that are unlikely to conflict with other skills. The niche is well-defined and narrow.

The skill is fairly well-structured but includes some unnecessary verbosity. The 'Why This Structure Helps Cursor' section explains things Claude can infer, and some of the example rule files are quite lengthy when patterns could be shown more concisely. However, most content is practical and not padded with basic concept explanations.

The skill provides fully concrete, copy-paste ready configuration files including complete .mdc rule examples with proper YAML frontmatter, .cursorignore contents, directory structures, and a monorepo variant. Every section contains specific, executable configuration rather than abstract guidance.

The layered rules architecture (Layer 1-4) provides a clear organizational hierarchy, and the configuration summary table is helpful. However, there's no explicit workflow for setting up a new project (step-by-step sequence), no validation checkpoints (e.g., how to verify rules are being applied correctly), and no troubleshooting guidance for common issues.

The content is well-organized with clear section headers and a logical progression from basic layout to monorepo patterns. However, at ~200 lines this is a substantial document that could benefit from splitting detailed rule examples into separate reference files. The external resource links at the end are helpful but the inline content is heavy for a single SKILL.md.
