Can I use this skill with an existing project?

Yes, harness-init is designed to analyze existing codebases and introduce the necessary harness files to enable autonomous development cycles.

What is the 'Solo' vs '2-Agent' mode?

Solo mode is optimized for a single AI developer, while 2-Agent mode configures the environment for collaborative AI workflows, often triggered automatically if tools like Cursor are detected.

What files does harness-init generate?

It creates core project files via tools like create-next-app along with specialized AI management files including Plans.md, AGENTS.md, CLAUDE.md, and a .claude/ configuration directory.

Do I need to manually configure the tech stack?

While you can specify a stack like --stack=next-supabase, the skill uses smart defaults and auto-determination to minimize the questions you need to answer.
