# Specialist-agent coordination

A `SKILL.md` does not create a live agent. True subagents require host runtime support or an explicitly configured authenticated service. Lead chooses scoped, independent roles from architecture, operations diagnosis, security review, Terraform/GitOps review, and verifier. Budget parallelism to genuinely independent subtasks. No simultaneous edits to same files/infra. Reviewers do not mutate production, and all changes remain approval-gated.

Specialist handoff contains task ID, input evidence, decisions, commands actually run, artifacts, risks, remaining questions and verified status. Resolve contradictions before reporting. If the host lacks subagents, work sequentially and do not fabricate delegation.
