CTO Platform Skill

Comprehensive knowledge of the CTO (Cognitive Task Orchestrator) platform for AI-driven development workflows.

When to Use

• Running intake to generate tasks from PRDs
• Starting and monitoring Play workflows
• Understanding agent sequencing and responsibilities
• Debugging workflow issues

Intake Workflow

MCP Tool

mcp_cto_intake(project_name="my-project")

Flow

PRD Document → mcp_cto_intake() → Linear Project Created
                                → PRD Issue with Morgan as delegate
                                → PM Webhook → Argo Workflow
                                → Morgan Pod generates tasks.json
                                → Task issues created in Linear

Key Points

• local: false in cto-config.json = Argo workflow (production)
• local: true = local binary execution (debugging only)
• Morgan auto-assigned triggers intake via PM webhook

Play Workflow

MCP Tools

mcp_cto_play()           # Start workflow, auto-detects next task
mcp_cto_play_status()    # Query progress
mcp_cto_jobs()           # List running workflows
mcp_cto_stop_job()       # Cancel workflow
