Workspace Management

Workspaces are directories managed by sgai. There are three kinds:

• Standalone — independent workspace, not part of a fork tree
• Root — has one or more fork children (displayed in dashboard/fork mode)
• Fork — child of a root workspace, shares the jj VCS repository

Create a Workspace

Endpoint: POST /api/v1/workspaces

curl -X POST $BASE_URL/api/v1/workspaces \
  -H "Content-Type: application/json" \
  -d '{"name": "my-project"}'

Request:

{"name": "my-project"}

Response (201 Created):

{
  "name": "my-project",
  "dir": "/path/to/workspaces/my-project"
}

Errors:

• 400 — invalid name (must be lowercase letters, numbers, dashes)
• 409 — directory already exists

Name Validation Rules

• Only lowercase letters (a-z), numbers (0-9), and dashes (-)
• Cannot start or end with a dash
• No spaces or special characters

Fork a Workspace

Create a jj workspace fork for parallel development.

Endpoint: POST /api/v1/workspaces/{name}/fork

curl -X POST $BASE_URL/api/v1/workspaces/my-project/fork \
  -H "Content-Type: application/json" \
  -d '{"name": "feature-branch"}'

Request:

{"name": "feature-branch"}

Response (201 Created):

{
  "name": "feature-branch",
  "dir": "/path/to/workspaces/feature-branch",
  "parent": "my-project",
  "createdAt": ""
}

Notes:

• Only standalone or root workspaces can be forked (forks cannot fork)
• Fork names are normalized (spaces become dashes, etc.)
• The fork shares the jj repository with the root via jj workspace add

Delete a Fork

Endpoint: POST /api/v1/workspaces/{name}/delete-fork

Where {name} is the root workspace name.

curl -X POST $BASE_URL/api/v1/workspaces/my-project/delete-fork \
  -H "Content-Type: application/json" \
  -d '{"forkDir": "/full/path/to/fork", "confirm": true}'

Request:

{
  "forkDir": "/full/path/to/workspaces/feature-branch",
  "confirm": true
}

Response:

{
  "deleted": true,
  "message": "fork deleted successfully"
}

Notes:

• confirm: true is required (safety guard)
• The running session is stopped before deletion
• Uses jj workspace forget then removes the directory
• When a root workspace runs out of forks, it reverts from Fork Mode to Repository Mode

Rename a Fork

Only fork workspaces can be renamed (not standalone or root).

Endpoint: POST /api/v1/workspaces/{name}/rename

curl -X POST $BASE_URL/api/v1/workspaces/feature-branch/rename \
  -H "Content-Type: application/json" \
  -d '{"name": "new-feature-name"}'

Request:

{"name": "new-feature-name"}

Response:

{
  "name": "new-feature-name",
  "oldName": "feature-branch",
  "dir": "/path/to/workspaces/new-feature-name"
}

Errors:

• 400 — workspace is not a fork
• 409 — session is running (stop first) or name conflict

Toggle Pin

Pin workspaces to keep them prioritized at the top of the list.

Endpoint: POST /api/v1/workspaces/{name}/pin

curl -X POST $BASE_URL/api/v1/workspaces/my-project/pin

Response:

{
  "pinned": true,
  "message": "pin toggled"
}

Update Workspace Summary

Set a human-readable summary for a workspace (shown in the UI).

Endpoint: PUT /api/v1/workspaces/{name}/summary

curl -X PUT $BASE_URL/api/v1/workspaces/my-project/summary \
  -H "Content-Type: application/json" \
  -d '{"summary": "Implementing authentication module"}'

Response:

{
  "updated": true,
  "summary": "Implementing authentication module",
  "workspace": "my-project"
}

Update Commit Description

Endpoint: POST /api/v1/workspaces/{name}/description

curl -X POST $BASE_URL/api/v1/workspaces/my-project/description \
  -H "Content-Type: application/json" \
  -d '{"description": "feat: add authentication endpoints"}'
