Vibekit Init

Vibe Kit Init

Initialize the kit safely.

Required behavior

1. Print the requirements checklist from .vibekit/init/FIRST_TIME_INIT.md.
2. Run or emulate detection, including repo-specific conventions, project mode, and PRD presence:

node .vibekit/scripts/init-backbone.mjs . --propose

1. Run the project-understanding step below.
2. Run the Codex setup preference below when Codex is installed and supports it.
3. Propose a unified diff for backbone.yml, its conventions rules, managed blocks, any new .vibekit/docs/PRD.md, and approved Codex preference files.
4. Ask: Apply this proposed backbone and convention rules? Reply yes, edit, or abort.
5. Write only after explicit yes.
6. Validate after writing.

Project understanding (PRD)

Detection reports project.mode (greenfield = no source yet, brownfield = existing code) and whether a PRD exists.

• Always offer a short interview, regardless of whether docs already exist: what the project is and who it is for, the core problem and primary focus now, what success looks like, key constraints/non-goals, and (brownfield) which area to improve first.
• If no PRD is found, propose creating .vibekit/docs/PRD.md from .vibekit/docs/templates/PRD_TEMPLATE.md using the answers, and set project.prd to that path.
• If a PRD exists, read it, link it in project.prd, and offer to refresh it without overwriting unapproved content.
• Keep the PRD short; it captures intent, not a full spec. Record domain terms in .vibekit/docs/CONTEXT.md (scaffold from .vibekit/docs/templates/CONTEXT_TEMPLATE.md) and link it in project.context.

Codex setup preference

Follow the three-choice Codex structured questions in Default mode procedure in .vibekit/init/FIRST_TIME_INIT.md. Recommend Yes with its short benefit, treat No as temporary, persist Don't show this again as project-local dismissal, and never edit the user's global ~/.codex/config.toml. Include any resulting .codex/config.toml or .vibekit/preferences.json change in the approval diff.

Convention detection

• Infer naming, directory layout, architecture, shared resource access, localization/message access, generated definitions, and per-app/package differences from existing files.
• Prefer existing constants, registries, generated APIs, and helper modules over hardcoded literals when the repo already has them.
• If no convention is clear, mark it as not detected and ask before introducing a broad new pattern.
• Store confirmed project rules in backbone.yml under conventions; later work must follow those rules unless the user edits them.

Merge policy

• Never overwrite existing CLAUDE.md or AGENTS.md.
• Replace only content between Minimal Vibe managed markers.
• Preserve user content outside managed markers.
• Keep CLAUDE.md and AGENTS.md concise.

Completion

Report initialized status, validation command, validation result, PRD path, and next recommended skill. Once the user confirms setup is complete, offer graduation (node .vibekit/scripts/vibekit-finalize.mjs . --propose) to move one-time bootstrap files into the cleanup folder.
