Cobuilder

This skill should be used when the user asks to "brainstorm a feature", "create a PRD", "write a solution design", "plan a new initiative", "start a new project", "ideate on a feature", "brainstorm and build", "go from idea to implementation", "generate a TDD pipeline", or when System 3/Guardian needs to drive the complete ideation → PRD → SD → worktree → autonomous TDD pipeline. Parent skill for CoBuilder orchestration-level workflows. For worker-level powers (TDD, debugging, verification), see the separate worker-superpowers skill.

CoBuilder Orchestration Workflows

High-level workflows for the CoBuilder multi-agent pipeline, inspired by superpowers. These sub-skills are used by System 3, Guardian, and Orchestrators — not by workers directly.

For worker-level powers (TDD, debugging, verification, brainstorming), see Skill("worker-superpowers").

Sub-Skills

Sub-Skill	Invoke As	Purpose
ideation-to-execution	`Skill("cobuilder:ideation-to-execution")`	Brainstorm → PRD → SD → Worktree → TDD Pilot
tdd-pipeline	`Skill("cobuilder:tdd-pipeline")`	Generate and configure TDD pipeline DOT files

Quick Start

Full Initiative (System 3 / Guardian)

Skill("cobuilder:ideation-to-execution")  # 5-phase workflow: brainstorm → PRD → SD → worktree → pilot

Generate Pipeline Only

Skill("cobuilder:tdd-pipeline")           # Instantiate tdd-validated template from SD

Brief Workers on Powers

When creating worker task assignments, include:

"Load Skill('worker-superpowers') for TDD workflow, systematic debugging, and verification."

Core Principles

Never jump to code — Discover → Design → Plan → Execute
Test first — Every feature starts with a failing test (via worker-superpowers)
Blind acceptance tests — Write tests from PRD before any implementation
Isolated execution — Workers run in worktrees with scoped file access
Pipeline-driven — DOT graph defines execution order, not ad-hoc delegation
