- Multi-agent coding requires explicit coordination to prevent merge conflicts, duplicated implementations, semantic contradictions, and context exhaustion.
- Six key patterns ensure reliable parallel coding: spec-driven decomposition, git worktree isolation, coordinator/specialist/verifier role split, task-to-model routing, verification and quality gates, and sequential merge strategies.
- Spec-driven decomposition breaks large changes into small, testable tasks with clear boundaries to reduce agent overlap.
- Git worktree isolation gives each agent a separate working directory and index, deferring conflicts to intentional merge points.
- A coordinator/specialist/verifier architecture separates planning, execution, and validation to reduce drift and duplicated work.
- BYOA (Bring Your Own Agent) routing matches model capability to task risk, using strong reasoning models for high-stakes decisions and faster models for routine iteration.
- Verification and quality gates automate regression detection through layered tests, static checks, and AI review before human review.
- Sequential merge strategies integrate branches one at a time, rebasing each onto the latest main to reduce surprise conflicts.
- Intent packages these six patterns into a single workspace with living specs, isolated workspaces, and automated git workflow integration.
