This is a solid, highly actionable reference skill for Bun's bundler with excellent executable code examples covering CLI, JavaScript API, plugins, and common patterns. Its main weaknesses are moderate verbosity from redundant sections (target environments, overlapping CLI/API docs) and the lack of actual bundle files to support the referenced progressive disclosure structure. The workflow could benefit from more explicit validation steps for production build processes.
Suggestions
Consolidate the Target Environments section into a brief note (e.g., 'Set target to "browser", "bun", or "node"') rather than three nearly identical code blocks.
Move the CLI flags table and loaders table into the referenced files (references/options.md) to reduce the main skill's token footprint and actually implement the progressive disclosure that's promised.
Add an explicit production build workflow with validation steps: clean output dir → build → check result.success → verify output files exist → optional size reporting.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is mostly efficient with good code examples, but includes some redundancy—the target environments section repeats nearly identical code blocks three times with only the target value changed, and the CLI flags table largely duplicates information already shown in the Bun.build options. The loaders table and some sections could be tightened. | 2 / 3 |
Actionability | Excellent actionability throughout—every section provides fully executable, copy-paste ready code examples for both CLI and JavaScript API usage. The common patterns section gives complete, real-world build configurations, and the build output section shows how to handle results including error checking. | 3 / 3 |
Workflow Clarity | The Quick Start and Build Script sections show a clear build-then-check-errors flow, and the common errors table is helpful. However, there's no explicit multi-step workflow with validation checkpoints for production builds (e.g., clean dist → build → validate output → deploy), and the build process lacks feedback loops for error recovery beyond a simple exit. | 2 / 3 |
Progressive Disclosure | The skill references three separate files (references/options.md, references/plugins.md, references/macros.md) with clear loading conditions, which is good structure. However, no bundle files are provided, so these references don't actually exist, and the main SKILL.md itself is quite long (~250 lines) with content like the full CLI flags table and loaders table that could be offloaded to reference files. | 2 / 3 |
