Crate astrid_runtime 

Astrid Runtime - Agent orchestration and session management.

This crate provides:

• Agent runtime with LLM, MCP, and security integration
• Session management with persistence
• Context management with auto-summarization

Architecture

The runtime coordinates:

• LLM provider for language model interactions
• MCP client for tool execution
• Capability store for authorization
• Audit log for security logging

Example

use astrid_runtime::{AgentRuntime, RuntimeConfig, SessionStore};
use astrid_llm::{ClaudeProvider, ProviderConfig};
use astrid_mcp::McpClient;
use astrid_audit::AuditLog;
use astrid_crypto::KeyPair;

// Create components
let llm = ClaudeProvider::new(ProviderConfig::new("api-key", "claude-sonnet-4-20250514"));
let mcp = McpClient::from_default_config()?;
let audit_key = KeyPair::generate();
let runtime_key = KeyPair::generate();
let audit = AuditLog::in_memory(audit_key);
let home = astrid_core::dirs::AstridHome::resolve()?;
let sessions = SessionStore::from_home(&home);

// Create runtime
let runtime = AgentRuntime::new(
    llm,
    mcp,
    audit,
    sessions,
    runtime_key,
    RuntimeConfig::default(),
);

// Create a session
let mut session = runtime.create_session(None);

// Run a turn (would need a Frontend implementation)
// runtime.run_turn_streaming(&mut session, "Hello!", &frontend).await?;
