Struct ToolContext 

pub struct ToolContext {
    pub workspace: PathBuf,
    pub session_id: Option<String>,
    pub event_tx: Option<ToolEventSender>,
    pub agent_event_tx: Option<Sender<AgentEvent>>,
    pub search_config: Option<SearchConfig>,
    pub sandbox: Option<Arc<dyn BashSandbox>>,
    pub command_env: Option<Arc<HashMap<String, String>>>,
}

Tool execution context

Provides tools with access to workspace and other runtime information.

Fields

workspace: PathBuf

Workspace root directory (sandbox boundary)

session_id: Option<String>

Optional session ID for session-aware tools

event_tx: Option<ToolEventSender>

Optional sender for streaming tool output deltas during execution

agent_event_tx: Option<Sender<AgentEvent>>

Optional agent event sender for tools that emit high-level agent events (e.g., SubagentStart)

search_config: Option<SearchConfig>

Optional search configuration for web_search tool

sandbox: Option<Arc<dyn BashSandbox>>

Optional sandbox for routing bash tool execution through A3S Box.

command_env: Option<Arc<HashMap<String, String>>>

Optional command environment overrides for subprocess-based tools.
