Create an isolated workspace directory with git repo copies (worktrees or clones) and an independent `.planning/` directory. Supports multi-repo orchestration and single-repo feature branch isolation.

1. Setup

MANDATORY FIRST STEP — Execute init command:

_GSD_SHIM_NAME="gsd-tools.cjs"; _GSD_RUNTIME_ROOT="${RUNTIME_DIR:-$(git rev-parse --show-toplevel 2>/dev/null || pwd)}"; GSD_TOOLS="${_GSD_RUNTIME_ROOT}/gsd-core/bin/${_GSD_SHIM_NAME}"; if [ -f "$GSD_TOOLS" ]; then gsd_run() { node "$GSD_TOOLS" "$@"; }; elif [ -f "${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="${_GSD_RUNTIME_ROOT}/.claude/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; elif command -v gsd-tools >/dev/null 2>&1; then GSD_TOOLS="$(command -v gsd-tools)"; gsd_run() { "$GSD_TOOLS" "$@"; }; elif [ -f "$HOME/.claude/gsd-core/bin/${_GSD_SHIM_NAME}" ]; then GSD_TOOLS="$HOME/.claude/gsd-core/bin/${_GSD_SHIM_NAME}"; gsd_run() { node "$GSD_TOOLS" "$@"; }; else echo "ERROR: gsd-tools.cjs not found at $GSD_TOOLS and gsd-tools is not on PATH. Run: npx -y @opengsd/gsd-core@latest --claude --local" >&2; exit 1; fi
INIT=$(gsd_run query init.new-workspace)
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi

Parse JSON for: default_workspace_base, child_repos, child_repo_count, worktree_available, is_git_repo, cwd_repo_name, project_root.

2. Parse Arguments

Extract from $ARGUMENTS:

• --name → WORKSPACE_NAME (required)
• --repos → REPO_LIST (comma-separated paths or names)
• --path → TARGET_PATH (defaults to $default_workspace_base/$WORKSPACE_NAME)
• --strategy → STRATEGY (defaults to worktree)
• --branch → BRANCH_NAME (defaults to workspace/$WORKSPACE_NAME)
• --auto → skip interactive questions

If --name is missing and not --auto:

Text mode (workflow.text_mode: true in config or --text flag): Set TEXT_MODE=true if --text is present in $ARGUMENTS OR text_mode from init JSON is true. When TEXT_MODE is active, replace every AskUserQuestion call with a plain-text numbered list and ask the user to type their choice number. This is required for non-Claude runtimes (OpenAI Codex, Gemini CLI, etc.) where AskUserQuestion is not available. Use AskUserQuestion:

• header: "Workspace Name"
• question: "What should this workspace be called?"
• requireAnswer: true

3. Select Repos

If --repos is provided: Parse comma-separated values. For each value:

• If it's an absolute path, use it directly
• If it's a relative path or name, resolve against $project_root
• Special case: . means current repo (use $project_root, name it $cwd_repo_name)

If --repos is NOT provided and not --auto:

If child_repo_count > 0:

Present child repos for selection:

Use AskUserQuestion:

• header: "Select Repos"
• question: "Which repos should be included in the workspace?"
• options: List each child repo from child_repos array by name
• multiSelect: true

If child_repo_count is 0 and is_git_repo is true:

Use AskUserQuestion:

• header: "Current Repo"
• question: "No child repos found. Create a workspace with the current repo?"
• options:
  • "Yes — create workspace with current repo" → use current repo
  • "Cancel" → exit

If child_repo_count is 0 and is_git_repo is false:

Error:

No git repos found in the current directory and this is not a git repo.

Run this command from a directory containing git repos, or specify repos explicitly:
  /gsd:workspace --new --name my-workspace --repos /path/to/repo1,/path/to/repo2

Exit.

If --auto and --repos is NOT provided:

Error:

Error: --auto requires --repos to specify which repos to include.

Usage:
  /gsd:workspace --new --name my-workspace --repos repo1,repo2 --auto

Exit.

4. Select Strategy

If --strategy is provided: Use it (validate: must be worktree or clone).

If --strategy is NOT provided and not --auto:

Use AskUserQuestion:

• header: "Strategy"
• question: "How should repos be copied into the workspace?"
• options:
  • "Worktree (recommended) — lightweight, shares .git objects with source repo" → worktree
  • "Clone — fully independent copy, no connection to source repo" → clone

If --auto: Default to worktree.

5. Validate

Before creating anything, validate:

1. Target path — must not exist or must be empty:

if [ -d "$TARGET_PATH" ] && [ "$(ls -A "$TARGET_PATH" 2>/dev/null)" ]; then
  echo "Error: Target path already exists and is not empty: $TARGET_PATH"
  echo "Choose a different --name or --path."
  exit 1
fi

2. Source repos exist and are git repos — for each repo path:

if [ ! -d "$REPO_PATH/.git" ]; then
  echo "Error: Not a git repo: $REPO_PATH"
  exit 1
fi

3. Worktree availability — if strategy is worktree and worktree_available is false:

Error: git is not available. Install git or use --strategy clone.

Report all validation errors at once, not one at a time.

6. Create Workspace

mkdir -p "$TARGET_PATH"

For each repo:

Worktree strategy:

cd "$SOURCE_REPO_PATH"
git worktree add "$TARGET_PATH/$REPO_NAME" -b "$BRANCH_NAME" 2>&1

If git worktree add fails because the branch already exists, try with a timestamped branch:

TIMESTAMP=$(date +%Y%m%d%H%M%S)
git worktree add "$TARGET_PATH/$REPO_NAME" -b "${BRANCH_NAME}-${TIMESTAMP}" 2>&1

If that also fails, report the error and continue with remaining repos.

Clone strategy:

git clone "$SOURCE_REPO_PATH" "$TARGET_PATH/$REPO_NAME" 2>&1
cd "$TARGET_PATH/$REPO_NAME"
git checkout -b "$BRANCH_NAME" 2>&1

Track results: which repos succeeded, which failed, what branch was used.

7. Write WORKSPACE.md

Write the workspace manifest at $TARGET_PATH/WORKSPACE.md:

# Workspace: $WORKSPACE_NAME

Created: $DATE
Strategy: $STRATEGY

## Member Repos

| Repo | Source | Branch | Strategy |
|------|--------|--------|----------|
| $REPO_NAME | $SOURCE_PATH | $BRANCH | $STRATEGY |
...for each repo...

## Notes

[Add context about what this workspace is for]

8. Initialize .planning/

mkdir -p "$TARGET_PATH/.planning"

9. Report and Next Steps

If all repos succeeded:

Workspace created: $TARGET_PATH

  Repos: $REPO_COUNT
  Strategy: $STRATEGY
  Branch: $BRANCH_NAME

Next steps:
  cd "$TARGET_PATH"
  /gsd:new-project    # Initialize GSD in the workspace

If some repos failed:

Workspace created with $SUCCESS_COUNT of $TOTAL_COUNT repos: $TARGET_PATH

  Succeeded: repo1, repo2
  Failed: repo3 (branch already exists), repo4 (not a git repo)

Next steps:
  cd "$TARGET_PATH"
  /gsd:new-project    # Initialize GSD in the workspace

Offer to initialize GSD (if not --auto):

Use AskUserQuestion:

• header: "Initialize GSD"
• question: "Would you like to initialize a GSD project in the new workspace?"
• options:
  • "Yes — run /gsd:new-project" → tell user to cd "$TARGET_PATH" first, then run /gsd:new-project
  • "No — I'll set it up later" → done

<success_criteria>

• Workspace directory created at target path
• All specified repos copied (worktree or clone) into workspace
• WORKSPACE.md manifest written with correct repo table
• .planning/ directory initialized at workspace root
• User informed of workspace path and next steps </success_criteria>
