What's New in v1.8.0
symbi init — Project Initialization
Interactive project scaffolding with profile-based templates. Choose from minimal, assistant, dev-agent, or multi-agent profiles with configurable SchemaPin verification and sandbox tiers. Includes a built-in agent catalog for importing pre-built governed agents.
symbi init # interactive wizard
symbi init --profile dev-agent --no-interact # CI/scripted
symbi init --catalog list # browse agent catalogInter-Agent Communication Governance
All inter-agent builtins (ask, delegate, send_to, parallel, race) are now routed through the CommunicationBus with policy evaluation via the new CommunicationPolicyGate. Cedar-style rules control which agents can communicate, with priority-based evaluation and hard deny on policy violations. Messages are cryptographically signed (Ed25519), encrypted (AES-256-GCM), and audited.
