Frequently Asked Questions about Superpowers

Cosa sono Superpowers per Claude Code?

Superpowers è un skill marketplace creato da obra che estende Claude Code con file SKILL.md frontmatter-based: ogni skill è un modulo riutilizzabile (brainstorming, debugging, TDD-guide, code-reviewer, refactor-cleaner) che Claude Code richiama automaticamente via description matching. Non è un framework di runtime: è una convenzione di organizzazione skill che sfrutta l'auto-discovery built-in di Claude Code.

Come funziona lo skill auto-discovery?

Quando Claude Code parte legge la cartella `~/.claude/skills/` (e quella locale al progetto) ed indicizza ogni file SKILL.md. Il modello sceglie quale skill invocare in base al matching tra description nel frontmatter e contesto dell'utente - niente registrazione esplicita, niente import. Per scrivere skill che il modello invoca davvero serve description chirurgica (5-15 parole concrete) + esempi inline + when-to-invoke esplicito.

Posso scrivere skill custom o devo usare solo quelli di obra?

Skill custom è il caso d'uso più comune. La SKILL.md è solo Markdown con frontmatter YAML - puoi scriverla a mano in 10 minuti o partire dal template ufficiale obra. Sul mio portfolio (federicocalo.dev) uso 6 skill custom: brainstorming, debugging, TDD-guide, code-reviewer, refactor-cleaner, doc-updater - clonate dalla struttura obra ma adattate al monorepo Angular+SpringBoot+FastAPI. Trovi gli estratti reali nello skill-pack OSS gratuito linkato in fondo a questa pagina.
