Agent skills
Skills you can use with AI coding agents, indexed from public GitHub repositories.
-
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.
