• src/api/group-milestones.ts:91-101 (handler)

  Handler for the delete_group_milestone tool, implementing the API call to delete a milestone from a group.

  export async function deleteGroupMilestone(groupId: string, milestoneId: number): Promise<void> {
    if (!groupId?.trim()) {
      throw new Error("Group ID is required");
    }
    if (!milestoneId || milestoneId < 1) {
      throw new Error("Valid milestone ID is required");
    }
  
    const endpoint = `/groups/${encodeURIComponent(groupId)}/milestones/${milestoneId}`;
    await gitlabDelete(endpoint);
  }

• src/schemas.ts:385-388 (schema)

  Zod schema for validating arguments to the delete_group_milestone tool.

  export const DeleteGroupMilestoneSchema = z.object({
    group_id: z.string().describe("Group ID or URL-encoded path"),
    milestone_id: z.number().describe("The ID of the group milestone")
  });

• src/server.ts:384-386 (registration)

  Tool registration/invocation logic for delete_group_milestone in the main server handler.

  case "delete_group_milestone": {
    const args = DeleteGroupMilestoneSchema.parse(request.params.arguments);
    await api.deleteGroupMilestone(args.group_id, args.milestone_id);
