Give an AI agent a repo it can actually understand,
and a harness it cannot escape.

AGENT HARNESS BOOTSTRAP
  • No standard to follow
  • Hallucinates requirements
  • Forgets everything on compaction

spec-builderwrites the contract
harness-bootstrapbuilds the boundary
the harness the agent runs inside agent

A controlled, model-independent
agent system
