Multi-Claude parallel builds for Claude Code.

Turn large tasks into packet graphs. Multiple Claude sessions execute in parallel waves while you observe, intervene, and approve through a unified control plane.

Features

Everything an operator needs to run parallel Claude sessions.

Packet Graphs

Break work into small, independently claimable units with explicit file ownership and dependency edges.

Fitness Assessment

Deterministic fit scoring from work class, packet count, coupling level, and ownership clarity.

Live Console

5-pane operator console: overview, packets, workers, hooks, fitness — with auto-refresh and next-action guidance.

Operator Intervention

Stop runs, retry packets, resolve hooks, approve gates — with full audit trail and lawful refusal.

Evidence Handoff

12-law handoff spine: execution through promotion. Review-readiness rules, fingerprint-locked approvals.

1600+ Tests

Comprehensive test suite covering control plane, handoff spine, monitor commands, and contract guards.
