golang-cli

Golang CLI application development. Use when building, modifying, or reviewing a Go CLI tool — especially for command structure, flag handling, configuration layering, version embedding, exit codes, I/O patterns, signal handling, shell completion, argument validation, and CLI unit testing. Also triggers when code uses cobra, viper, or urfave/cli. For cobra-specific APIs → See `samber/cc-skills-golang@golang-spf13-cobra` skill; for viper configuration layering → See `samber/cc-skills-golang@golang-spf13-viper` skill.

Quality

Content

78%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.

Well-structured, actionable content that delegates code to real example files and provides strong review checklists. Main improvement area is adding explicit build/test validation checkpoints and trimming minor over-explanation.

Suggestions

Add an explicit validation checkpoint to the Build mode workflow, e.g. 'After flag binding, run `go build ./... && go test ./...` before proceeding'.

Trim non-essential context like the 'powers kubectl, docker, gh, hugo' name-drop and the reminder to consult official Cobra/Viper docs, which Claude already knows to do.

Inline one small canonical snippet (e.g. a minimal root command skeleton) so the most common case is copy-paste ready without opening a referenced file.

DimensionReasoningScore

Conciseness

Largely lean with tables and pointers to example files rather than inlined code, but includes minor over-explanation such as 'This combination powers kubectl, docker, gh, hugo' and 'refer to the library's official documentation' that could be trimmed.

4 / 5

Actionability

Concrete MUST/SHOULD directives, a Quick Reference package table, and validator/exit-code tables plus real example files make guidance mostly executable, though the code itself lives in referenced files rather than inline.

4 / 5

Workflow Clarity

Build mode gives a sequential section order and the Common Mistakes table plus Review mode provide a review checklist, but explicit validation checkpoints (e.g. 'run go build && go test') are only implicit.

4 / 5

Progressive Disclosure

Clear overview in SKILL.md with well-signaled one-level-deep markdown links to assets/examples/*.go; all 12 referenced files exist and content is appropriately split between overview and example files.

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 trigger guidance and clear boundary management via sibling-skill delegation. It clearly answers both what the skill does and when to invoke it.

DimensionReasoningScore

Specificity

Lists many concrete actions — 'command structure, flag handling, configuration layering, version embedding, exit codes, I/O patterns, signal handling, shell completion, argument validation, and CLI unit testing' — giving comprehensive coverage of the domain.

5 / 5

Completeness

Explicitly answers both what ('Golang CLI application development') and when ('Use when building, modifying, or reviewing a Go CLI tool', 'Also triggers when code uses cobra, viper, or urfave/cli') with concrete trigger phrases.

5 / 5

Trigger Term Quality

Good natural keyword coverage including 'Go CLI tool', 'cobra, viper, or urfave/cli', but a few natural terms/synonyms (e.g. 'command line', '.go files') are missing.

4 / 5

Distinctiveness Conflict Risk

Clear niche (Go CLI tooling) with explicit delegation to sibling skills for cobra- and viper-specific concerns, minimizing overlap and conflict risk.
