golang-modernize

Modernize Golang code to use recent language features, standard library improvements, and idiomatic patterns. Trigger proactively when writing or reviewing Go code and old-style patterns are detected, or when encountering a deprecation warning. Also use when the user explicitly asks for modernization, a Go version upgrade, or a CI/tooling refresh.

Content

85%

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

The body is highly actionable and well-structured, with strong progressive disclosure and a validated multi-step workflow. The only drag is mild redundancy from restating the full-scan sub-agent plan and re-narrating the description.

Suggestions

Remove the duplicate five-sub-agent description: keep it in the Modes/Full-scan section and have workflow step 7 cross-reference it instead of re-listing the categories.

Delete or compress the opening restatement ("This skill helps you continuously modernize Go codebases...") since the frontmatter description already covers it.

Consolidate the repeated worktree-isolation rationale (Modes section and step 7) into a single mention.

Dimension	Reasoning	Score
Conciseness	Mostly efficient dense tables, but the five-sub-agent full-scan description is restated (Modes section and workflow step 7) and the opening re-narrates the description; these could be tightened.	2 / 3
Actionability	Concrete package-replacement tables with "Since" versions, a versioned migration priority guide, specific commands (go mod tidy, golangci-lint, govulncheck), and a copy-ready .modernize file format.	3 / 3
Workflow Clarity	A nine-step sequenced workflow with explicit validation (run tests, verify compatibility), a consent check, and worktree isolation for the batch rewrite — checkpoints are present rather than implicit.	3 / 3
Progressive Disclosure	SKILL.md is a concise overview with clearly signaled one-level-deep links to real files (./references/versions.md, ./references/tooling.md); detailed before/after examples are correctly pushed to references.	3 / 3

Description

100%

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 description: third-person voice, concrete actions, explicit trigger guidance for both proactive and explicit use, and a well-scoped niche. It cleanly satisfies all four dimensions.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — "use recent language features, standard library improvements, and idiomatic patterns" plus "Go version upgrade" and "CI/tooling refresh" — rather than vague abstractions.	3 / 3
Completeness	Explicitly states what it does ("Modernize Golang code...") and when to trigger via a clear "Trigger proactively when... Also use when..." clause covering both contextual and explicit invocations.	3 / 3
Trigger Term Quality	Covers natural terms a user would say: "modernization", "Go version upgrade", "CI/tooling refresh", "deprecation warning", and "writing or reviewing Go code".	3 / 3
Distinctiveness Conflict Risk	The Go-modernization niche with triggers tied to old-style patterns and deprecation warnings is clearly distinct from general Go skills and unlikely to misfire.	3 / 3
