Codebase Onboarding

Adapted from ECC's codebase-onboarding skill (MIT).

Systematically analyze an unfamiliar codebase and produce a structured onboarding guide. Designed for developers joining a new project or setting up OpenCode in an existing repo for the first time.

When to Use

• First time opening a project with OpenCode
• Joining a new team or repository
• User asks "help me understand this codebase"
• User asks to generate a AGENTS.md for a project
• User says "onboard me" or "walk me through this repo"

See REFERENCE.md for full phase details, onboarding guide template, AGENTS.md template, and examples.
