AgentSmith

What it is

Most agents forget everything when the process stops. AgentSmith wraps an agent built with the Rust Rig framework and records every turn in a SQLite database with full-text search, the way Atuin does for shell history. Before each reply, it searches past conversations for relevant turns and adds them to the prompt.

Using it

use agentsmith::{AgentHistory, SmartAgent};
use rig::providers::openai;

let history = AgentHistory::new("my_agent.db", Some("session-123")).await?;

let client = openai::Client::new(&std::env::var("OPENAI_API_KEY")?);
let agent = client.agent("gpt-4").preamble("You are a helpful assistant.").build();

let mut smart = SmartAgent::new(agent, history);
let reply = smart.chat("How did we fix the JSON parsing bug?").await?;

AgentHistory can also be used directly: log_turn records a message with metadata (duration, success, tokens), search and recent retrieve turns, summarize_session writes a summary, and import_jsonl loads an existing log.

Ideas for using it

• A coding assistant that remembers your project’s past bugs and fixes.
• Support bots that recall a customer’s earlier conversations.
• Agent analytics: search all sessions for failures and see what preceded them.

Status

Prototype; built for Rig agents. SQLite only.
