Struct ResolvedContext 

pub struct ResolvedContext {
    pub system_instruction: String,
    pub active_tools: Vec<Arc<dyn Tool>>,
}

Core traits and types.

Always available regardless of feature flags. Includes:

• Agent - The fundamental trait for all agents
• Tool / Toolset - For extending agents with capabilities
• Session / State - For managing conversation context
• Event - For streaming agent responses
• AdkError / Result - Unified error handling A validated context containing engineered instructions and resolved tool instances.

This structure serves as the “Atomic Unit of Capability” for an agent. It guarantees that the agent’s cognitive frame (the instructions telling it what it can do) is perfectly aligned with its physical capabilities (the binary tool instances bound to the session).

By using ResolvedContext, the framework eliminates “Phantom Tool” hallucinations, where an agent tries to call a tool that was mentioned in its prompt but never actually registered in the runtime.

Fields

system_instruction: String

The engineered system instruction.

active_tools: Vec<Arc<dyn Tool>>

The resolved, executable tools.
