Multi Workspace

Multi (multi-workspace on PyPI) is a CLI tool that enables VS Code/Cursor to work across multiple Git repos in a single workspace. Sub-repos are cloned as directories inside the workspace root and .gitignored — no submodules are used. The CLI keeps all repos on the same branch and merges their VS Code configurations.

Key Constraints

• multi init is interactive and cannot be scripted non-interactively.
• Automation flow should use multi.json + multi sync (not multi init).
• CLAUDE.md and AGENTS.md are auto-generated from .cursor/rules/*.mdc files. Never edit them directly.
• All repos must have clean working directories before running multi set-branch.
• multi set-branch and multi git are disabled in monorepo mode.
• VS Code config files (settings.json, launch.json, tasks.json, extensions.json) at the workspace root are generated — do not edit directly. Use the repo-level files or *.shared.json files instead.
• In monoRepo mode, directories listed in repos should be part of the root git repo and must not contain nested .git folders.

Commands

multi sync

Run all sync operations: clone/symlink repos, update .gitignore, merge VS Code configs, sync Cursor rules, sync ruff config.

Subcommands for partial sync:

• multi sync vscode — merge all VS Code configs (or specify: settings, launch, tasks, extensions, devcontainer)
• multi sync rules — generate CLAUDE.md/AGENTS.md from Cursor rules and create repo-directories.mdc from repo descriptions
• multi sync ruff — copy ruff config from a sub-repo to workspace root

multi set-branch BRANCH_NAME

Switch all repos to a branch. If the branch exists locally or on the remote, check it out. If it doesn't exist anywhere, create it from the current HEAD. All repos must be clean first.

multi git GIT_ARGS...

Run any git command across all repos (root first, then sub-repos in order). All repos must be on the same branch. Example: multi git pull, multi git push -u origin feature/foo.

multi init

Interactive setup: prompts for repo URLs and descriptions, writes multi.json, clones repos, runs full sync, commits.

multi doctor

Diagnose workspace issues (missing/invalid multi.json, root git initialization, and monoRepo nested .git mismatches). Use --strict to fail on warnings.

multi open PATH

Open a project path in the Multi desktop app.

Configuration Overview

The workspace is configured via multi.json at the root. Key fields:

• repos[] — array of repo configs, each with url, optional name, description, skipVSCode, allowSymlink, requiredTasks, requiredCompounds, requiredLaunchConfigurations
• monoRepo — treat repos as local subdirectories instead of cloning
• allowSymlinks — enable symlinking to existing clones from ~/.multi/repos.json
• vscode.skipSettings — settings keys to exclude from merge

For the full schema, consult references/configuration.md.

VS Code Merging Overview

Multi merges .vscode/ config files from all sub-repos into the workspace root:

• ${workspaceFolder} rewriting — paths are automatically prefixed with the repo name
• *.shared.json files — settings.shared.json, launch.shared.json, tasks.shared.json at workspace root are merged last (for cross-repo config)
• Master compound — auto-created launch compound and task containing all "required" entries
• Settings overrides — per-repo vscode.settingsOverrides in multi.json

For detailed merging behavior, consult references/vscode-sync.md.

CLAUDE.md / AGENTS.md Generation

Running multi sync rules:

1. Generates .cursor/rules/repo-directories.mdc from repo description fields in multi.json.
2. For each directory containing .cursor/rules/*.mdc, concatenates all rule bodies into CLAUDE.md and AGENTS.md placed alongside the .cursor directory.
3. If no rules exist, removes existing CLAUDE.md/AGENTS.md.

Common Tasks

Automate workspace setup: Create/update multi.json, then run multi sync.

Add a new repo to the workspace: Add a url entry (and optional name/description) to the repos array in multi.json, then run multi sync.

Switch all repos to a feature branch: Run multi set-branch feature/my-branch. Ensure all repos are clean first.

Diagnose mode mismatches: Run multi doctor (or multi doctor --strict for CI enforcement).

Fix a missing launch config: Check the source repo's .vscode/launch.json. Ensure skipVSCode is not true for that repo. Run multi sync vscode launch. For cross-repo compounds, use .vscode/launch.shared.json at workspace root.

Add cross-repo settings: Create or edit .vscode/settings.shared.json at the workspace root, then run multi sync vscode settings.
