Quality

Content

71%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A highly actionable, well-structured guide that is held back by verbosity and a monolithic single-file layout that inlines reference material. Splitting the API/mock references into bundled files and trimming introductory prose would improve it.

Suggestions

Move the 'Common Assertion Methods', 'Mock Argument Matchers', and 'Mock Return Values' reference blocks into separate files under references/ and link to them from SKILL.md to reduce inline bulk and improve progressive disclosure.

Trim explanatory prose about well-known concepts (e.g., what table-driven tests are, the TDD cycle intro) and keep only the testify-specific guidance to improve conciseness.

Add explicit validation/verification checkpoints (e.g., 'run go test ./... after each refactor; only proceed when green') to the TDD and mock workflows to strengthen workflow clarity.

Dimension	Reasoning	Score
Conciseness	Mostly efficient code-heavy content, but includes explanatory prose Claude already knows ('The idiomatic Go pattern for testing multiple scenarios', TDD cycle exposition, 'Critical distinction: Choose based on whether the test should continue after failure') that could be trimmed.	3 / 5
Actionability	Provides abundant copy-paste-ready, executable Go examples covering assert/require, table-driven tests, mocking, suites, and the TDD cycle across the common cases.	5 / 5
Workflow Clarity	The TDD red-green-refactor section is a clearly numbered sequence with run-the-test feedback loops, but validation checkpoints are not emphasized uniformly across the other sections.	4 / 5
Progressive Disclosure	Section headers organize the content well, but this is a ~480-line single file with reference material (Common Assertion Methods, Mock Argument Matchers, Mock Return Values) inlined that would be better split into separate reference files.	3 / 5

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong, specific description with explicit 'what' and 'when' guidance and low conflict risk. Trigger-term coverage is good but could add a few more natural synonyms.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'writing Go tests with stretchr/testify', 'creating mocks', 'organizing test suites', 'assert vs require patterns', 'interface mocking', 'table-driven tests', and 'red-green-refactor cycle' — giving comprehensive coverage of the skill's capabilities.	5 / 5
Completeness	Explicitly answers 'when' via 'Use this skill when writing Go tests with stretchr/testify, implementing TDD workflows, creating mocks, or organizing test suites' and 'what' via 'Covers assert vs require patterns, interface mocking, table-driven tests, and the red-green-refactor cycle.'	5 / 5
Trigger Term Quality	Includes natural terms users would say ('Go tests', 'TDD workflows', 'mocks', 'test suites', 'testify'), but a few common synonyms like 'unit tests' or 'stubbing' are not surfaced in the description itself.	4 / 5
Distinctiveness Conflict Risk	Targets a clear niche (testify-based Go testing with TDD) with distinct triggers, making conflict with unrelated skills minimal.	5 / 5
