Automated README summary
Automatically summarized from the README on 24 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A Python toolkit of prebuilt agents for browser use, computer use, games and robotics, plus a builder for custom agents. Each agent uses a System 1 decision model (Jev, Laya, Cua-S1) in place of a chat model for decision turns.
How it uses Jev
On a decision turn the agent's model slot receives the state and the options; Jev answers with one option and a probability per option. The agent then acts on that choice, while planning and the final answer stay with the chat model. `s1a decide` exposes one such decision directly.
Primitives:choice
Technique worth stealing
Put a System 1 model in the openJiuwen agent's model slot so it only picks among typed options, leaving planning and text to the chat model.
Try it
git clone, uv sync, set TYPESAFE_API_KEY in .env, then `uv run s1a decide --state ... --option ...`.
Model judgments from README excerpts
Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence
These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
