Workspace Protocol — Shared File-Based Agent Communication

Multi-agent workflows can be coordinated using a file-based shared workspace that turns the filesystem into a deterministic coordination bus, replacing fragile handoffs with a fixed directory structure and STATUS.md-driven progress model for auditability.

A file-based shared workspace is a structured coordination model where the filesystem serves as the single source of truth for multi-agent orchestration, enforcing a fixed directory layout with stage-specific files for deterministic handoffs across BRS, architecture, implementation, and code review.

Initialize a workspace under .kiro/workspace/{feature-name}/ and populate STATUS.md alongside per-stage output directories like 01-brs.md and 05-implementation to begin coordinating deterministic multi-agent handoffs through the filesystem.

Yes, the workspace protocol supports parallel reviews and status tracking by utilizing the shared filesystem, allowing multiple agents to read and write only their designated stage-specific inputs and outputs while maintaining clear progress across complex pipelines.

Use a filesystem coordination bus when orchestrating complex multi-agent pipelines that require deterministic handoffs, auditability, and a single source of truth to prevent confusion and drift across stages like architecture planning, tests, and code review.
