• src/index.ts:497-510 (registration)

  Registration of the 'delete_space' tool in the listTools handler, including its input schema.

          name: 'delete_space',
          description: 'Delete a space and all its contents',
          inputSchema: {
              type: 'object',
              properties: {
                  space_duid: {
                      type: 'string',
                      description: 'DUID of the space to delete'

• src/index.ts:1106-1159 (handler)

  The handler for 'delete_space' tool. It generates Python code that uses the Dart client to create a DELETE operation on the SPACE model with the given space_duid and executes it via transact with SPACE_DELETE transaction kind.
