85%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
A well-structured, highly actionable Go-testing reference with clean executable examples, clear per-mode workflows, an explicit verification loop, and a sound one-level-deep reference split. The main weakness is mild verbosity: a few Claude-known concept restatements and overlap between the summary list and the detailed sections.
Suggestions
Trim Claude-known restatements (e.g. 'Table-driven tests are the idiomatic Go way to test multiple scenarios', 'Examples are executable documentation verified by go test', 'Use t.Parallel() to run tests concurrently') to lift conciseness.
Reduce redundancy between the 13-item Best Practices Summary and the detailed sections — either shrink the summary to non-obvious rules only or drop the rules restated verbatim below.
Consider moving the full testing/synctest section into a reference file (like the HTTP/integration/mocking splits) since it is a sizeable inline block on a single Go-version feature.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Mostly efficient with executable code, but includes Claude-known asides ('Table-driven tests are the idiomatic Go way', 'Examples are executable documentation verified by go test', 'Use t.Parallel() to run tests concurrently') and the 13-item Best Practices Summary substantially restates the detailed sections below. | 2 / 3 |
Actionability | Abundant copy-paste-ready executable Go code and bash commands — table-driven test scaffolds, goleak/synctest setups, coverage commands, and the Quick Reference block — fully meeting the 'executable, complete' anchor. | 3 / 3 |
Workflow Clarity | Four modes (Write/Review/Audit/Debug) each give an explicit sequence, the 13-item summary acts as a checklist, and the assert-scope pitfall includes an explicit verify→diagnose feedback loop ('Verify with a deliberately-broken case: if go test -v ... shows --- FAIL but every subtest says PASS, the assert scope is leaking'). | 3 / 3 |
Progressive Disclosure | Body is an overview that signals one-level-deep references to real bundle files (http-testing.md, helpers.md, integration-testing.md, mocking.md) and cross-refs benchmarks/testify to sibling skills; detail is appropriately split out and all referenced paths exist. | 3 / 3 |
