# gantt-tasks

**Module Skill** - Complete task management for Gantt Board via API.

## Purpose

Provides all operations needed to work with Gantt Board tasks: create, read, update, delete, comments, attachments, and sprint queries. Used by orchestrator skills and agents.

## Authentication

Uses **machine token** for server-to-server API calls:

```bash
export GANTT_MACHINE_TOKEN="50cd5e8fe3f895353f97c9ee64052c0b689b4eedf79259746413734d0a163cf8"
export GANTT_API_URL="https://gantt-board.vercel.app/api"
```

**Architecture:** Skills → API (with machine token) → Database

This follows the API-centric pattern where all business logic lives in API routes.

## Usage

```bash
source ~/.agents/skills/gantt-tasks/lib/tasks.sh

# Create task
TASK_ID=$(task_create --title "Fix bug" --project "Gantt Board" --sprint current)

# Add comment
task_add_comment "$TASK_ID" "Starting work on this"

# Attach file
task_attach_file "$TASK_ID" "/path/to/file.md"
```

## File Structure

```
~/.agents/skills/gantt-tasks/
├── SKILL.md              # This documentation
└── lib/
    └── tasks.sh          # All task functions
```

## Integration Example

Complete workflow:

```bash
# Set authentication
export GANTT_MACHINE_TOKEN="50cd5e8fe3f895353f97c9ee64052c0b689b4eedf79259746413734d0a163cf8"
export GANTT_API_URL="https://gantt-board.vercel.app/api"

source ~/.agents/skills/gantt-tasks/lib/tasks.sh

# 1. Create task
TASK_ID=$(task_create \
    --title "Research URL extraction options" \
    --type research \
    --priority high \
    --sprint current)

echo "Created task: $TASK_ID"

# 2. Add initial comment
task_add_comment "$TASK_ID" "Starting research phase" --checklist

# 3. Update with progress
task_update "$TASK_ID" --status in-progress
task_add_comment "$TASK_ID" "Evaluated 3 options:\n1. Scrapling\n2. Tavily\n3. web_fetch" \
    --checklist \
    --status in-progress

# 4. Attach recommendation
cat > /tmp/recommendation.md << 'EOF'
## Recommendation

Use Scrapling as primary, Tavily as fallback.

- Scrapling handles JavaScript sites
- Tavily fast for articles
- web_fetch for simple sites
EOF

task_attach_file "$TASK_ID" /tmp/recommendation.md --description "Research findings"

# 5. Mark ready for review
task_update "$TASK_ID" --status review
task_add_comment "$TASK_ID" "Research complete. Recommendation attached." \
    --checklist

echo "Task ready for review: https://gantt-board.vercel.app/tasks/$TASK_ID"
```

## CLI Alternative

For interactive/command-line use, use the Gantt Board CLI:

```bash
# Set auth for CLI
export GANTT_MACHINE_TOKEN="50cd5e8fe3f895353f97c9ee64052c0b689b4eedf79259746413734d0a163cf8"
export API_URL="https://gantt-board.vercel.app/api"

cd /Users/mattbruce/Documents/Projects/OpenClaw/Web/gantt-board

# Create task
./scripts/gantt.sh task create "Title" --type research --sprint current

# List tasks
./scripts/gantt.sh task list --sprint current --status in-progress

# Get task
./scripts/gantt.sh task get $TASK_ID

# Update task
./scripts/gantt.sh task update $TASK_ID --status review
```

**Note:** The skill library and CLI both use the same API endpoints with machine token authentication.
