Multi-agent orchestration for SDK feature implementation is coordinated through a plan-first approach using parallel validators and per-work-stream supervisors, ensuring artifacts are produced in Docs/plans while enforcing phase order and strict file ownership rules.

A plan-first approach for supervised feature builds validates the plan with parallel validators before execution, then applies layered execution across foundation, supervisors, and final documentation updates to ensure traceable outputs and artifact tracing.

To start the supervised multi-agent implementation workflow, provide the handoff document and plan to initiate the process, which will then coordinate validators, supervisors, and living-doc updates across CLAUDE.md and PLAYBOOK.md.

Parallel validators can verify plan correctness before execution by running validation checks during the planning phase, ensuring the supervised multi-agent workflow only proceeds once the plan is fully validated.

The multi-agent orchestration enforces strict file ownership rules alongside phase order and artifact tracing, ensuring each work-stream supervisor respects ownership boundaries while producing plan, validation, completion, and review artifacts.

Plan-first orchestration for feature builds requires a completed handoff document and plan before initiation, and enforces strict phase order, meaning out-of-phase execution or missing artifacts will halt the supervised multi-agent workflow.
