Lists multiple specific concrete actions and artifacts: ANSI color nesting rules, message patterns, output system architecture, and names specific functions (warning_message, hint_message, error_message, info_message, eprintln, println).

Clearly answers both 'what' (CLI output formatting standards, ANSI color nesting rules, message patterns, output system architecture) and 'when' ('Load before editing any code that calls warning_message, hint_message, error_message, info_message, eprintln, or println, or that produces strings the user will see').

Excellent coverage of natural trigger terms a developer would encounter: specific function names (warning_message, hint_message, error_message, info_message, eprintln, println), domain terms (CLI output, ANSI color, CLI help, progress UI, snapshot text), and the project name 'worktrunk'.

Highly distinctive — scoped to a specific project ('worktrunk'), a specific domain (CLI output formatting), and lists exact function names as triggers. Very unlikely to conflict with other skills.

The skill is extensive and mostly contains project-specific conventions Claude wouldn't know, which is appropriate. However, there's some redundancy (e.g., the same patterns are shown multiple times with GOOD/BAD examples that could be consolidated), and some sections like the shell integration architecture could be tighter. The document is long but most content earns its place as project-specific guidance.

The skill provides highly concrete, executable Rust code examples throughout, specific function names with their modules, exact formatting patterns with GOOD/BAD comparisons, and precise rules (e.g., use `@` not 'at', use `<underline>` in hints not `<bold>`). Every guideline is illustrated with copy-paste-ready code or concrete examples.

The skill covers many individual formatting decisions clearly, but lacks an overarching workflow for 'how to add output to a new command.' Decision trees are provided for some areas (warning placement, stdout vs stderr) which is good, but there's no validation/verification step for checking output conformance. The warning ordering section and prompt spacing section have clear sequences, but the document as a whole reads more as a reference than a workflow.

The document is a monolithic ~600-line file covering architecture, formatting standards, error formatting, styling, path formatting, table alignment, and snapshot testing all inline. There are references to source files (e.g., 'See src/git/error.rs', 'See src/commands/list/render.rs') which is good, but the content itself would benefit from being split into separate files (e.g., architecture, message patterns, styling guide, error formatting) with a concise overview in the main SKILL.md. No bundle files are provided to offload detail.
