ALTK‑Evolve: On‑the‑Job Learning for AI Agents

ALTK-Evolve is a long-term memory system that transforms raw AI agent trajectories into reusable principles, significantly boosting reliability in complex, multi-step tasks.

Most AI agents re‑read transcripts instead of learning principles, so they repeat mistakes and don’t transfer lessons to new situations.
ALTK‑Evolve turns raw agent trajectories into reusable guidelines, acting as a long-term memory subsystem.
In benchmarks like AppWorld, the approach boosted reliability significantly, especially on hard tasks (Δ 14.2%), by distilling principles rather than just bloating context.
The system operates in a continuous loop: capturing trajectories, extracting patterns, and refining them into a high-quality library of SOPs and policies.
It offers flexible integration paths: a Lite mode for Claude Code, a low-code version via Arize Phoenix, and a pro-code integration via MCP for advanced workflows.
Evaluation shows that the harder the task, the more the agent benefits from concise learned guidelines, leading to more consistent and less "flaky" behavior.
