## Features Implemented
### Core Functionality ✅
- **Query project timelines** with task lists and statistics
- **Check task dependencies** and blocking relationships
- **Calculate critical path** using Critical Path Method (CPM) algorithm
- **Get project status overviews** with completion metrics
- **Filter tasks** by status, priority, assignee, due date
- **PDA-friendly language** - supportive, non-judgmental tone
### API Integration ✅
Full support for Mosaic Stack API endpoints:
- `GET /api/projects` - List projects (paginated)
- `GET /api/projects/:id` - Get project with tasks
- `GET /api/tasks` - List tasks with filters
- `GET /api/tasks/:id` - Get task details
**Authentication:**
- `X-Workspace-Id` header (from `MOSAIC_WORKSPACE_ID`)
- `Authorization: Bearer` header (from `MOSAIC_API_TOKEN`)
### TypeScript Client Features ✅
- **Strict typing** - No `any` types, comprehensive interfaces
- **Type-safe responses** - Full TypeScript definitions for all models
- **Error handling** - Proper error messages and validation
- **Helper methods:**
- `listProjects()` - Paginated project listing
- `getProject(id)` - Get project with tasks
- `getTasks(filters)` - Query tasks
- `getProjectTimeline(id)` - Timeline with statistics
- `getDependencyChain(taskId)` - Resolve dependencies
- `calculateCriticalPath(projectId)` - CPM analysis
- `getTasksApproachingDueDate()` - Due date filtering
### Bash Script Features ✅
Command-line interface via `gantt-api.sh`:
- `projects` - List all projects
- `project <id>` - Get project details
- `tasks [project-id]` - Get tasks (with optional filter)
- `task <id>` - Get task details
- `dependencies <id>` - Show dependency chain
- `critical-path <id>` - Calculate critical path
## Critical Path Algorithm
Implements the Critical Path Method (CPM):
1. **Forward Pass** - Calculate earliest start times
- Build dependency graph from task metadata
- Calculate cumulative duration for each path
2. **Backward Pass** - Calculate latest start times
- Work backwards from project completion
- Find latest allowable start without delaying project
3. **Slack Calculation** - Identify critical vs non-critical tasks
- Slack = Latest Start - Earliest Start
- Critical tasks have zero slack
4. **Path Identification** - Order critical tasks chronologically
- Build longest dependency chain
- Identify bottlenecks and parallel work
## Data Models
### Project
```typescript
{
id: string;
name: string;
status: 'PLANNING' | 'ACTIVE' | 'ON_HOLD' | 'COMPLETED' | 'ARCHIVED';
startDate?: Date;
endDate?: Date;
tasks?: Task[];
_count: { tasks: number; events: number };
}
```
### Task
```typescript
{
id: string;
title: string;
status: 'NOT_STARTED' | 'IN_PROGRESS' | 'PAUSED' | 'COMPLETED' | 'ARCHIVED';
priority: 'LOW' | 'MEDIUM' | 'HIGH' | 'URGENT';
dueDate?: Date;
completedAt?: Date;
metadata: {
startDate?: Date;
dependencies?: string[]; // Task IDs that block this task
};
}
```
## Usage Examples
### Via Clawdbot (Natural Language)
```
User: "Show me the timeline for Q1 Release"
User: "What blocks the deployment task?"
User: "What's the critical path for our project?"
User: "Show all high-priority tasks due this week"
User: "Give me a status overview of Project Beta"
```
### Via CLI (Bash Script)
```bash
# Set up environment
export MOSAIC_API_URL="http://localhost:3000/api"
export MOSAIC_WORKSPACE_ID="your-workspace-uuid"
export MOSAIC_API_TOKEN="your-api-token"
# List all projects
./gantt-api.sh projects
# Get project timeline
./gantt-api.sh project abc-123
# Get tasks for a project
./gantt-api.sh tasks abc-123
# Show dependency chain
./gantt-api.sh dependencies task-456
# Calculate critical path
./gantt-api.sh critical-path abc-123
```
### Via TypeScript
```typescript
import { createGanttClientFromEnv } from '@mosaic/skills/gantt';
const client = createGanttClientFromEnv();
// Get timeline with stats
const timeline = await client.getProjectTimeline('project-id');
console.log(`Completed: ${timeline.stats.completed}/${timeline.stats.total}`);
// Calculate critical path
const criticalPath = await client.calculateCriticalPath('project-id');
console.log(`Critical path: ${criticalPath.totalDuration} days`);
// Get dependency chain
const deps = await client.getDependencyChain('task-id');
console.log(`Blocked by: ${deps.blockedBy.length} tasks`);
```
## PDA-Friendly Language
Uses supportive, non-judgmental language per requirements:
-**"Target passed"** instead of "OVERDUE" or "LATE"
-**"Approaching target"** instead of "DUE SOON"
-**"Paused"** instead of "BLOCKED" or "STUCK"
- ✅ Focus on accomplishments and next steps

description: Query and analyze project timelines, task dependencies, and schedules from Mosaic Stack's Gantt/Project API
license: MIT
---
This skill enables querying project timelines, task dependencies, critical path analysis, and project status from Mosaic Stack's API.
## Overview
The Mosaic Stack provides project management capabilities with support for:
- Project timelines with start/end dates
- Task dependencies and scheduling
- Task status tracking (NOT_STARTED, IN_PROGRESS, PAUSED, COMPLETED, ARCHIVED)
- Priority levels (LOW, MEDIUM, HIGH, URGENT)
- Project status (PLANNING, ACTIVE, ON_HOLD, COMPLETED, ARCHIVED)
## API Endpoints
**Base URL**: Configured via `MOSAIC_API_URL` environment variable (default: `http://localhost:3000`)
### Projects
- `GET /projects` - List all projects with pagination
- `GET /projects/:id` - Get project details with tasks
### Tasks
- `GET /tasks` - List all tasks with optional filters
- Query params: `projectId`, `status`, `priority`, `assigneeId`, `page`, `limit`
## Authentication
Requests require authentication headers:
- `X-Workspace-Id`: Workspace UUID (from `MOSAIC_WORKSPACE_ID` env var)
- `Authorization`: Bearer token (from `MOSAIC_API_TOKEN` env var)
## Trigger Phrases & Examples
**Query project timeline:**
- "Show me the timeline for [project name]"
- "What's the status of [project]?"
- "Give me an overview of Project Alpha"
**Check task dependencies:**
- "What blocks task [task name]?"
- "What are the dependencies for [task]?"
- "Show me what's blocking [task]"
**Project status overview:**
- "Project status for [project]"
- "How is [project] doing?"
- "Summary of [project]"
**Identify critical path:**
- "Find the critical path for [project]"
- "What's the critical path?"
- "Show me blockers for [project]"
- "Which tasks can't be delayed in [project]?"
**Find upcoming deadlines:**
- "What tasks are due soon in [project]?"
- "Show me tasks approaching deadline"
- "What's due this week?"
## Data Models
### Project
```typescript
{
id: string;
name: string;
description?: string;
status: 'PLANNING' | 'ACTIVE' | 'ON_HOLD' | 'COMPLETED' | 'ARCHIVED';
startDate?: Date;
endDate?: Date;
color?: string;
tasks?: Task[];
_count: { tasks: number; events: number };
}
```
### Task
```typescript
{
id: string;
title: string;
description?: string;
status: 'NOT_STARTED' | 'IN_PROGRESS' | 'PAUSED' | 'COMPLETED' | 'ARCHIVED';
priority: 'LOW' | 'MEDIUM' | 'HIGH' | 'URGENT';
dueDate?: Date;
completedAt?: Date;
projectId?: string;
assigneeId?: string;
metadata: {
startDate?: Date;
dependencies?: string[]; // Array of task IDs
[key: string]: any;
};
}
```
## Helper Scripts
Use `gantt-api.sh` for API queries:
```bash
# List all projects
./gantt-api.sh projects
# Get project by ID
./gantt-api.sh project <project-id>
# Get tasks for a project
./gantt-api.sh tasks <project-id>
# Find critical path
./gantt-api.sh critical-path <project-id>
# Get dependency chain for a task
./gantt-api.sh dependencies <task-id>
```
## PDA-Friendly Language
When presenting information, use supportive, non-judgmental language:
- **"Target passed"** instead of "OVERDUE" or "LATE"
- **"Approaching target"** for near-deadline tasks
- **"Paused"** not "BLOCKED" or "STUCK"
- Focus on what's accomplished and what's next, not what's behind
## Implementation Notes
1. **Environment Setup**: Ensure `.env` has required variables:
- `MOSAIC_API_URL` - API base URL (e.g., `http://localhost:3000`, no `/api` suffix)
- `MOSAIC_WORKSPACE_ID` - Workspace UUID
- `MOSAIC_API_TOKEN` - Authentication token
2. **Error Handling**: API returns 401 for auth errors, 404 for not found
3. **Pagination**: Projects and tasks are paginated (default 50 items/page)
4. **Dependencies**: Task dependencies are stored in `metadata.dependencies` as array of task IDs
5. **Date Handling**: Start dates may be in `metadata.startDate` or fall back to `createdAt`
