@bernierllc/braingrid-cli-wrapper

Type-safe wrapper for the BrainGrid CLI that provides a clean, programmatic interface for interacting with BrainGrid projects, requirements, and tasks.

Overview

This package provides atomic utilities for interacting with the BrainGrid CLI in a type-safe manner. It wraps BrainGrid CLI commands with Zod schema validation, ensuring type safety and proper error handling.

Features

• Type-safe API: Full TypeScript support with Zod schema validation
• Error Handling: Custom error types with detailed error information
• CLI Integration: Seamless integration with BrainGrid CLI commands
• Schema Validation: Automatic validation of CLI responses using Zod schemas
• Minimal Dependencies: Only depends on execa and zod

Installation

npm install @bernierllc/braingrid-cli-wrapper

Quick Start

import { createIdea, listProjects, createTask } from '@bernierllc/braingrid-cli-wrapper';

// Create a new requirement (IDEA)
const requirement = await createIdea('Add OAuth2 authentication', 'proj-123');
console.log(`Created requirement ${requirement.id} with status ${requirement.status}`);

// List all projects
const projects = await listProjects();
console.log(`Found ${projects.length} projects`);

// Create a task under a requirement
const task = await createTask('req-456', {
  title: 'Build login UI',
  description: 'Create login form component',
  tags: ['DEV', 'frontend'],
  dependencies: ['task-100']
});
console.log(`Created task ${task.id}`);

API Reference

Commands

createIdea(prompt: string, projectId?: string): Promise<BrainGridRequirement>

Creates a new requirement (IDEA) in BrainGrid.

Input:

• prompt (string, required): Description of the requirement/idea
• projectId (string, optional): Project ID to associate with the requirement

Output:

• Returns a BrainGridRequirement object with:
  • id: Requirement ID
  • projectId: Associated project ID
  • title: Requirement title
  • status: Requirement status (IDEA, PLANNED, IN_PROGRESS, COMPLETED, CANCELLED, PAUSED)
  • description: Optional description
  • createdAt: Optional creation timestamp
  • updatedAt: Optional update timestamp

Example:

const req = await createIdea('Add user authentication system');
// { id: 'req-123', projectId: 'proj-456', title: 'Add user authentication system', status: 'IDEA' }

listProjects(): Promise<BrainGridProject[]>

Lists all projects in BrainGrid.

Input: None

Output:

• Returns an array of BrainGridProject objects with:
  • id: Project ID
  • name: Project name
  • description: Optional project description

Example:

const projects = await listProjects();
// [{ id: 'proj-1', name: 'My Project', description: 'Project description' }]

createTask(reqId: string, options: CreateTaskOptions): Promise<BrainGridTask>

Creates a task under a requirement.

Input:

• reqId (string, required): Requirement ID
• options (CreateTaskOptions, required):
  • title (string, required): Task title
  • description (string, optional): Task description
  • tags (string[], optional): Task tags
  • dependencies (string[], optional): Task dependency IDs

Output:

• Returns a BrainGridTask object with:
  • id: Task ID
  • reqId: Parent requirement ID
  • title: Task title
  • status: Task status (TODO, READY, BLOCKED, IN_PROGRESS, COMPLETED, FAILED, PAUSED)
  • description: Optional description
  • tags: Optional array of tags
  • dependencies: Optional array of dependency IDs

  tags: ['DEV', 'frontend'],
  dependencies: ['task-100']
});
// { id: 'task-456', reqId: 'req-123', title: 'Build login UI', status: 'TODO', ... }

listTasks(options?: ListTasksOptions): Promise<BrainGridTask[]>

Lists tasks with optional filters.

Input:

• options (ListTasksOptions, optional):
  • reqId (string, optional): Filter by requirement ID
  • status (TaskStatus[], optional): Filter by status array
  • tags (string[], optional): Filter by tags array

Output:

• Returns an array of BrainGridTask objects

Example:

// List all tasks
const allTasks = await listTasks();

// List tasks for a specific requirement
const reqTasks = await listTasks({ reqId: 'req-123' });

// List tasks by status
const inProgressTasks = await listTasks({ status: ['IN_PROGRESS'] });

// Combine filters
const filteredTasks = await listTasks({
  reqId: 'req-123',
  status: ['TODO', 'READY'],
  tags: ['DEV']
});

updateTaskStatus(taskId: string, options: UpdateTaskOptions): Promise<void>

Updates task status and metadata.

Input:

• taskId (string, required): Task ID to update
• options (UpdateTaskOptions, optional):
  • status (TaskStatus, optional): New task status
  • assignedTo (string, optional): Assignee ID
  • metadata (Record<string, unknown>, optional): Metadata object

Output: Promise that resolves when update is complete

Example:

// Update task status
await updateTaskStatus('task-123', { status: 'IN_PROGRESS' });

// Update with assignee
await updateTaskStatus('task-123', {
  status: 'IN_PROGRESS',
  assignedTo: 'user-456'
});

// Update with metadata
await updateTaskStatus('task-123', {
  status: 'IN_PROGRESS',
  metadata: { progress: 50, notes: 'Half done' }
});

  if (error instanceof BrainGridCliError) {
    console.error(`CLI command failed: ${error.command}`);
    console.error(`Exit code: ${error.exitCode}`);
    console.error(`Error output: ${error.stderr}`);
  }
}
