This is a comprehensive and highly actionable skill for tsdown with excellent concrete examples and good reference table organization. Its main weaknesses are excessive length (too many inline patterns that could be split into a separate file), lack of explicit build validation workflows, and a broken table in the Core References section. The content would benefit from being trimmed and restructured to keep the SKILL.md as a concise overview with patterns moved to a referenced file.
Suggestions
Move the 13+ 'Common Patterns' and 'Configuration Features' examples into a separate referenced file (e.g., references/patterns.md) to keep SKILL.md as a lean overview
Add explicit validation/verification steps to the workflow — e.g., after building, run `publint` and `attw` to verify the package is correctly structured before publishing
Fix the broken Core References table where the tsdown-migrate note interrupts the table rows (Hooks, Programmatic API, etc. are outside the table)
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is fairly comprehensive but includes some unnecessary verbosity — the 'When to Use' section lists things Claude can infer, and the extensive tables and many common patterns (13+ examples) make it quite long. Some patterns like the basic library bundle are repeated from the Basic Configuration section. However, most content is reference-worthy rather than explanatory fluff. | 2 / 3 |
Actionability | Excellent actionability with fully executable, copy-paste-ready configuration examples covering a wide range of use cases. CLI commands are concrete and specific, and every pattern includes complete TypeScript config objects that can be used directly. | 3 / 3 |
Workflow Clarity | The skill provides clear individual steps (install, configure, run) but lacks explicit validation checkpoints. There's no workflow for verifying the build output is correct, no error recovery guidance, and the migration workflow just says 'npx tsdown-migrate' without validation steps. For a build tool that could produce broken packages, validation steps (like running publint/attw checks) should be more prominently integrated into the workflow rather than just listed as options. | 2 / 3 |
Progressive Disclosure | The skill references many external files (references/*.md) via well-organized tables, which is good progressive disclosure structure. However, the SKILL.md itself is very long with 13+ inline code examples that could be in a separate patterns/examples file. The main file tries to be both a quick reference and a comprehensive cookbook, making it a borderline monolithic document. The broken table formatting (the tsdown-migrate note interrupts the Core References table) also hurts organization. | 2 / 3 |
