Action Parser

Action parser — extracts AgentAction from raw LLM text output.

Overview

The parser handles the conversion from raw LLM text output to structured AgentAction enum variants. It supports:

• Plain JSON objects
• JSON wrapped in markdown code fences (```json)
• Automatic whitespace trimming

Action Types

The parser recognizes three action types:

• final: Final response to the user
• tool_call: Request to execute a tool
• ask_user: Request for user input

Example

use bob_runtime::action::parse_action;
use bob_core::types::AgentAction;

let json = r#"{"type": "final", "content": "Hello!"}"#;
let action = parse_action(json)?;

match action {
    AgentAction::Final { content } => println!("Response: {}", content),
    _ => println!("Other action"),
}

Enums
