Automated README summary
Automatically summarized from the README on 27 Sept 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
Drives a real headless browser through an MCP server, CLI, or library. Give it a task and a URL; it navigates, fills forms, and returns the final page, a step trace, console errors, and a screenshot.
How it uses Jev
At each step, Jev picks one action from the page's clickable, typeable, and selectable elements, and scores how likely the goal is met or the run is stuck. Code owns the loop: budgets, recovery, stop gates.
Primitives:choicescore
Technique worth stealing
Let a typed model choose one action per step while code owns budgets, recovery, and stop gates.

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.
