Autobuild: Autonomous Plan Execution Engine

Execute entire implementation plans in a single pass with zero user intervention. Each phase runs in its own sub-agent, writing state to the filesystem. Context never exhausts because sub-agents are isolated.

Overview

Autobuild is an autonomous execution engine for superplan implementation plans. Unlike superbuild which stops after each phase for user confirmation, autobuild runs everything to completion.

Key Differences from superbuild:

Aspect	superbuild	autobuild
Execution	Phase-by-phase with stops	Continuous until complete
User intervention	Required after each phase	None (fully autonomous)
Context management	Manual compaction	Sub-agents isolate context
State persistence	In conversation	Filesystem (.autobuild/)
Resume capability	Manual	Automatic from state files
