Repository integration

Zero reads your repository for code context during sessions. It writes nothing to your repository without explicit approval.

What Zero reads

  • File structure (for code context)
  • Specific files referenced in case context
  • Git log (for diff generation and session context)

What Zero writes

  • Code changes during Work mode execution — only after the operator approves the session plan.
  • Nothing is written to your repository without plan approval.

GitHub integration

  • Issue import — Zero fetches issue metadata (title, body, labels, acceptance criteria) and writes problem-definition.md. Available.
  • PR ready-check — Zero can check PR status and surface blockers. Available.
  • Progress comments — Zero can post session progress as issue comments. Operator-controlled. Available.
  • Proof comment — Zero posts a proof summary as a PR comment when Work resolves. Available.

Required access

  • Repository read access (local filesystem).
  • GitHub: read issues, comment on issues, read PR status (if GitHub integration is enabled).
  • Zero does not require write access to the repository — code changes are applied locally and you create the PR.

Multi-repo and monorepos

Monorepo: Zero supports a single workspace directory — point it at the monorepo root. Code context can reference files across any package within the workspace.

Multiple repos: each Zero workspace is one directory. For multiple repos, open multiple workspaces. Cases in different workspaces are independent.

Team plan: allows multiple machines — each can have different workspaces pointing at different repos.

Each workspace is one directory. Cross-workspace Work item linking is not available in current releases.
