Unofficial CPU-first System One–compatible decision server with Playwright browser agent demo.

Agent Decisions1.00Runner-up: Classification & Routing
Automated README summary

Automatically summarized from the README on 20 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

A local FastAPI decision server plus a Playwright Chromium agent and operator console UI with 10 mainland-China-accessible site templates. For developers exploring browser automation without GPU or TypeSafe calls.

How it uses Jev

The demo/CLI agent snapshots interactive elements, ranks them, and asks System One for the next action; the default backend is a local keyword-overlap heuristic server exposing POST /v1/systemone. Tasks use deterministic selectors with the heuristic only as a light tie-break.

Technique worth stealing

Embed the headless browser as a Playwright JPEG stream over WebSocket instead of an iframe, avoiding X-Frame-Options/CSP blocking.

Try it

python -m venv .venv; pip install -e ".[dev]"; python -m playwright install chromium; run systemone and demo.

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.
