Description
Blacksmith removes the watching instead. A goal becomes a set of immutable spec contracts. Each contract runs in its own git worktree, under a token budget, over paths no other worker is allowed to touch. What merges is decided by gates — a schema check, tests, a reviewer that never saw the coder's session, and a verifier whose only job is to refute the reviewer. Your job shrinks to two touchpoints: agree on the spec, then review one pull request. Everything in between runs unattended.

Could you build this?
Partial While the agent scaffolding can be vibe-coded, building reliable sandboxed git worktree execution environments with deterministic schema validations and token-budget isolation is technically challenging.
What it would actually take: The architecture requires a container orchestration layer (like Docker or Firecracker microVMs) to safely run untrusted code across separate git worktrees, coupled with an orchestration worker engine (e.g., Temporal). The hardest parts are state isolation, preventing runaway processes, and robust deterministic multi-agent review gates that reliably compile and test code without human intervention.
