Idiomatic Go patterns and best practices — package design, error handling, interfaces, concurrency, testing, and project layout. Written by spf13 (former Go team lead, author of Cobra, Viper, Hugo, Afero).

Definitive guide to building CLI applications with Cobra and Viper — command-first architecture, configuration management, environment variable binding, and in-memory CLI testing. Written by spf13, the original creator of both libraries.

Review Go design documents before implementation begins — catches over-engineering, missing error paths, interface misuse, and Cobra/Viper convention violations while a plan is still cheap to change.

Release engineering for Go modules and applications — semantic versioning, breaking-change detection, deprecation conventions, go.mod hygiene, and binary distribution with GoReleaser.

Building native desktop applications in Go with Wails v2 (stable) and v3 (alpha). CRITICAL: v2 and v3 have incompatible APIs that LLMs constantly blend — this skill detects the version and follows only that version's patterns.

Safe file operations in Go using spf13/fileflow (move, copy, rename across filesystems with conflict-safe naming) and spf13/pathologize (make filenames and path segments safe on every OS).
