Struct AgentConfig 

pub struct AgentConfig {

    pub name: String,
    pub model: String,
    pub system_prompt: String,
    pub api_key: Option<String>,
    pub temperature: Option<f32>,
    pub max_tokens: Option<u32>,
    pub base_url: Option<String>,
    pub top_p: Option<f32>,
    pub top_k: Option<u32>,
    pub timeout_seconds: Option<u64>,
    pub reasoning: Option<bool>,
    pub reasoning_effort: Option<String>,
    pub memory: Option<MemoryConfig>,
    pub mcp_tools: Vec<McpToolConfig>,
}

Configuration for a single LLM agent.

This struct can be loaded from a TOML file and used to create an LlmAgent.

Example

name = "my_agent"
model = "ollama::gemma3:latest"
system_prompt = "You are a helpful assistant."
temperature = 0.7
max_tokens = 1024

Fields

name: String

Unique name for the agent

model: String

Model in “provider::model” format (e.g., “ollama::gemma3:latest”)

system_prompt: String

System prompt for the agent

api_key: Option<String>

API key for the LLM provider (optional, can use env vars)

temperature: Option<f32>

Temperature for generation (0.0 - 2.0)

max_tokens: Option<u32>

Maximum tokens to generate

base_url: Option<String>

Base URL override for the LLM provider

top_p: Option<f32>

Top-p (nucleus) sampling parameter

top_k: Option<u32>

Top-k sampling parameter

timeout_seconds: Option<u64>

Request timeout in seconds

reasoning: Option<bool>

Enable reasoning mode (for supported providers)

reasoning_effort: Option<String>

Reasoning effort level

memory: Option<MemoryConfig>

Memory configuration for this agent (optional, overrides mesh default)

mcp_tools: Vec<McpToolConfig>

MCP tool configurations for this agent. Each entry defines an external MCP server that provides tools.

Implementations

impl AgentConfig

pub fn new(name: impl Into<String>, model: impl Into<String>) -> Self

Create a new AgentConfig with required fields.

pub fn from_toml(toml_str: &str) -> Result<Self>

Parse an AgentConfig from a TOML string.

Example

use enki_runtime::config::AgentConfig;

let toml = r#"
name = "my_agent"
model = "ollama::llama2"
"#;

let config = AgentConfig::from_toml(toml).unwrap();
assert_eq!(config.name, "my_agent");

pub fn from_file(path: impl AsRef<Path>) -> Result<Self>

Load an AgentConfig from a TOML file.

Example

use enki_runtime::config::AgentConfig;

let config = AgentConfig::from_file("agent.toml").unwrap();

pub fn with_system_prompt(self, prompt: impl Into<String>) -> Self

Set the system prompt.

pub fn with_api_key(self, api_key: impl Into<String>) -> Self

Set the API key.

pub fn with_temperature(self, temperature: f32) -> Self

Set the temperature.

pub fn with_max_tokens(self, max_tokens: u32) -> Self

Set max tokens.

pub fn with_memory(self, memory: MemoryConfig) -> Self

Set memory configuration for this agent.

pub fn get_effective_memory_config<'a>( &'a self, fallback: Option<&'a MemoryConfig>, ) -> Option<&'a MemoryConfig>

Get the effective memory configuration for this agent.

Returns the agent’s own memory config if set, otherwise returns the fallback (typically the mesh-level memory config).

Arguments

• fallback - The mesh-level memory config to use if agent has no memory config

Example

use enki_runtime::config::{AgentConfig, MemoryConfig, MeshConfig};

let mesh_memory = MemoryConfig::in_memory().with_max_entries(1000);
let agent = AgentConfig::new("agent1", "ollama::llama2");

// Agent without memory uses mesh fallback
let effective = agent.get_effective_memory_config(Some(&mesh_memory));
assert!(effective.is_some());

// Agent with its own memory uses that
let agent_with_memory = agent.with_memory(MemoryConfig::in_memory().with_max_entries(500));
let effective = agent_with_memory.get_effective_memory_config(Some(&mesh_memory));
assert_eq!(effective.unwrap().max_entries, Some(500));
