86%Weight 40%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured reference skill: actionable code, clear package-selection guidance, and clean progressive disclosure to three supporting files. The only slack is mild motivational verbosity in the 'Why' section.
Suggestions
Tighten the 'Why samber/lo' section: drop the persuasive framing and keep only the concrete stdlib-gap facts and the progressive-complexity rule, since the rest is inferable from the package table.
Fix the MapErr example's return type (http.Get returns (*http.Response, error), not (Response, error)) so the illustrative code is actually compileable.
Add a short explicit profile-then-switch feedback loop (e.g., 'go tool pprof -alloc_objects → if a lo transform dominates → switch to lom and re-measure') to turn the implicit workflow into a checkpointed one.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The body is dense and largely assumes Claude's Go competence, with no padding about what slices or generics are; the 'Why samber/lo' rationale section is the main mildly motivational content that could be trimmed, keeping it just below a 5. | 4 / 5 |
Actionability | Provides copy-paste-ready executable Go examples (Map, Filter+Reduce, GroupBy, MapErr), a real install command, alias/Go-version tables, a package-selection decision table, and a Common Mistakes table with concrete fixes covering common cases. | 5 / 5 |
Workflow Clarity | The package-selection flow is clearly sequenced ('Start with lo', escalate to lop/lom/loi only after profiling) with concrete thresholds (1000+ items, pprof -alloc_objects); no destructive/batch validation is required so no cap applies, but there is no explicit feedback-loop workflow to reach a 5. | 4 / 5 |
Progressive Disclosure | SKILL.md is a well-organized overview that pushes the complete function catalog and detailed patterns to three real, one-level-deep reference files (package-guide.md, api-reference.md, advanced-patterns.md), each clearly signaled with markdown links. | 5 / 5 |
