context boundary management

Grok uploading entire repos instead of task-relevant files is a failure to define and enforce context boundaries—a core context engineering concern

MCP servers enforce clear boundaries between agent context and external tool/data access, directly addressing context boundary clarity.

NSA explicitly discusses risks of implicit trust relationships and context sharing—these are failures in context boundary management across the MCP continuum.

MCP servers are the primary mechanism for managing what context Claude has access to, defining boundaries between Claude's native capabilities and external systems.

The orchestration layer's control of 'what gets shared, when it moves' is explicitly context boundary management between agents.

The article shows that MCP enforces type-safe boundaries at protocol level, but agents still leak secrets—revealing that context boundaries must be enforced at multiple layers (protocol, data isolatio

Each MCP server boundary is a context boundary requiring explicit trust/validation controls

MCP solves the problem of managing boundaries between AI context window and external context sources. Client/server model is explicit boundary architecture.

Reveals failure to establish clear boundaries between trusted system context and external content context

The three-layer defense architecture is fundamentally about managing what context each agent can access—input validation controls what data enters, authorization controls which agents see what data, t

Agent specialization inherently requires clear context boundaries—each agent needs defined inputs/outputs. A2A protocol is a context boundary mechanism.

MCP defines protocol boundaries for how agents access external context/data; this is context boundary management in practice

Worktree isolation (EnterWorktree/ExitWorktree) and plan mode (EnterPlanMode/ExitPlanMode) are explicit mechanisms for creating and managing context boundaries

Agent handoffs create context boundaries where information can be lost. The patterns discussed represent different strategies for managing these boundaries, though the article doesn't explicitly frame
