Unit 7 · Give agents memory and orientation

Stop re-exploring the same codebase

You give an agent a compact, persistent map of a recurring corpus. It begins oriented while still checking current evidence for each task.

See the idea in context

let analyst = agent_with_options(signature, json!({
    "contextFields": ["codebase"],
    "contextPolicy": {"preset": "adaptive", "budget": "balanced"},
    "contextMap": {"maxChars": 1800, "infiniteEvolve": false, "evolveSteps": 1},
}))?.with_runtime(Box::new(QuickJsCodeRuntime::new()))?;

Load prior orientation
savedSnapshot carries useful structure learned on earlier successful runs.
Keep the map compact
maxChars bounds what is injected into the agent context.
Use it as a guide
The map points the agent toward evidence but never replaces current source.

Run itIn your own project

cargo add axllm

use axllm::{ai, ax};
use serde_json::json;

let llm = ai("openai", json!({"apiKey": std::env::var("OPENAI_API_KEY")?}))?;
let classify = ax("review:string -> sentiment:class \"positive, negative, neutral\"")?;

Set OPENAI_APIKEY in your environment before running provider-backed code.
