57%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This is a well-organized skill that serves effectively as a hub document with clear progressive disclosure to reference files and related skills. Its main weaknesses are the lack of any inline code examples (all actionability is deferred to reference files that weren't provided for evaluation) and the somewhat verbose best practices list that could be tightened. The mode definitions add structure but lack concrete validation steps.
Suggestions
Add at least 2-3 inline executable code examples for the most critical patterns (e.g., error wrapping with %w, errors.Is usage, single handling rule violation vs correct pattern) so the SKILL.md is actionable on its own without requiring reference files.
Trim the 15-item best practices list — several items overlap (e.g., items 1/7 both relate to handling, items 10/12/13 all relate to logging). Consolidate to ~8-10 items to improve conciseness.
Add explicit validation steps to the Coding and Review modes — e.g., 'After implementing error handling, verify: no swallowed errors (grep for `_ =`), no log-and-return pairs, all wraps use %w internally.'
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The skill is reasonably efficient but includes some unnecessary verbosity — the persona section, mode descriptions, and the 15-item best practices summary repeat information that's elaborated in the references. The community default note and some explanatory parentheticals could be trimmed. However, it avoids explaining basic Go concepts Claude already knows. | 2 / 3 |
Actionability | The best practices summary provides specific guidance (use %w, use errors.Is/As, use slog) and names concrete functions and patterns, but the SKILL.md itself contains zero executable code examples. All concrete code is deferred to reference files that aren't provided. The rules are clear but not copy-paste ready. | 2 / 3 |
Workflow Clarity | The three modes (Coding, Review, Audit) provide some workflow structure, and the parallel sub-agent audit pattern is well-defined with clear categories. However, there are no validation checkpoints or feedback loops for any of the modes — particularly the coding and review modes lack explicit step sequences with verification steps. | 2 / 3 |
Progressive Disclosure | The skill is well-structured as an overview with clear one-level-deep references to three detailed reference files (error-creation.md, error-wrapping.md, error-handling.md), each with a descriptive summary. Cross-references to related skills are clearly signaled. The content is appropriately split between summary and detail. | 3 / 3 |
