Evidence-Based Future Direction Hypotheses

FeatureFeature DescriptionInference Basis
Multi-agent coordination as default workflowShift from single-turn helper to orchestrator with delegated/background tasks.AGENT_TRIGGERS, COORDINATOR_MODE, BG_SESSIONS, TEAMMEM appear across many runtime modules.
MCP as integration backboneMCP likely becomes the primary extensibility and enterprise integration layer.Dedicated MCP runtime plus multiple MCP-focused gates and tools.
Remote-first execution growthMore workflows likely execute in remote/session-managed contexts.BRIDGE_MODE, DIRECT_CONNECT, CCR_* and remote session manager modules.
Context economics as product moatLong-session reliability treated as core infra.CONTEXT_COLLAPSE, TOKEN_BUDGET, REACTIVE_COMPACT, HISTORY_SNIP in query/runtime paths.
Stronger policy-governed automationSecurity posture likely tightens around permissions and safer autonomous tool execution.Permission context + sandbox adapter + command classifiers in core execution paths.
