This is a well-structured skill that provides highly actionable, concrete guidance for running Fastly Compute WASM binaries locally with fastlike. Its greatest strengths are the executable CLI examples, comprehensive flag documentation, and excellent progressive disclosure to reference files. The main weaknesses are minor verbosity in places and the lack of explicit validation/error-recovery steps in the workflow.
Suggestions
Add a brief validation step after installation (e.g., `bin/fastlike -version` or a smoke test command) and mention common startup errors (e.g., port already in use, invalid WASM binary) with recovery guidance.
Trim the introductory paragraph that restates what the source code reference table already conveys to reduce redundancy.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is mostly efficient and avoids explaining basic concepts, but includes some redundancy — the Fastlike vs Viceroy comparison table partially repeats trigger/scope guidance, and the full configuration example could be trimmed since individual flags are already documented in the table. The source code reference table is valuable but the introductory paragraph restates what the table already shows. | 2 / 3 |
Actionability | Provides fully executable commands for installation, quick start, and multiple configuration scenarios. The CLI flags are documented with defaults and descriptions, and concrete bash examples are copy-paste ready with real flag combinations. | 3 / 3 |
Workflow Clarity | The install-build-run sequence is clear, and the profiling workflow has a logical progression. However, there are no explicit validation checkpoints — no guidance on verifying the WASM binary is valid before running, no error recovery steps if fastlike fails to start, and no verification that backends are reachable. For a tool that runs arbitrary WASM binaries, some validation guidance would be expected. | 2 / 3 |
Progressive Disclosure | Excellent structure with a clear overview in the main file and well-signaled one-level-deep references to specific topics (profiling.md, backends.md, config.md, abi.md, etc.). The references table at the bottom provides clear navigation with 'Use when...' context for each linked file. The source code reference table also serves as effective progressive disclosure into the codebase. | 3 / 3 |
