72%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a solid, actionable skill with excellent code examples and good progressive disclosure to advanced topics. Its main weaknesses are minor verbosity (persona block, best-practice explanations, a duplicated example) and the lack of validation/debugging checkpoints in the workflow — particularly around error handling when services fail to resolve or circular dependencies arise.
Suggestions
Remove the persona block and the 'This skill is not exhaustive' disclaimer — they consume tokens without adding actionable value for Claude.
Add a brief troubleshooting/validation section covering common failure modes: circular dependency errors, missing service panics from MustInvoke, and how to use injector.ListProvidedServices() or similar to verify wiring.
Trim best practices to just the rule statements without the explanatory clauses (e.g., 'Depend on interfaces, not concrete types' is sufficient without the dash explanation — Claude already understands why).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Generally efficient but has some unnecessary padding: the persona block, the explanation of why each best practice matters (Claude knows these), the 'This skill is not exhaustive' disclaimer, and the eager service example duplicates the ProvideValue line. The quick reference tables are useful but add length. | 2 / 3 |
Actionability | Provides fully executable, copy-paste-ready Go code for every concept: registration, invocation, dependency chains, implicit aliasing, named services, package organization, and a full application setup. All examples use real types and real function signatures. | 3 / 3 |
Workflow Clarity | The numbered steps (Define → Invoke → Dependencies) provide a clear sequence for basic usage, and the full application setup shows the composition root pattern. However, there are no validation checkpoints or error recovery guidance — e.g., what to do when Invoke fails, how to debug circular dependencies, or how to verify the container is correctly wired. | 2 / 3 |
Progressive Disclosure | Clear overview with well-signaled one-level-deep references to ./references/advanced.md and ./references/testing.md for scopes, lifecycle, and testing patterns. Cross-references to related skills are provided. The main file stays focused on core usage without inlining advanced content. | 3 / 3 |
