 **Want to use the prompts directly?** Copy-paste them into your AI assistant:
 
 1. **Generate a spec:** Copy `prompts/generate-spec.md` into your AI chat → AI assesses scope, asks structured questions (numbered/lettered options), optionally reviews codebase, generates spec, iterates with you → Spec saved to `docs/specs/01-spec-<feature-name>/01-spec-<feature-name>.md`
