Automated README summary
Automatically summarized from the README on 17 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.
What it is
A browser automation library, CLI and MCP server for LLM agents. The calling LLM states one outcome per step; code describes the page and Jev picks the element, action and value, while Playwright executes.
How it uses Jev
Each round, code describes the page (elements, labels, state, text, diff). One Jev request asks which element, which action, which value, and whether the step is done, blocked, erroring, or irreversible. Code turns low confidence or disagreement into a status the LLM acts on.
Primitives:choicescorenoul
Technique worth stealing
Move page reading to Jev: ask many typed questions per round so the LLM never reads snapshots unless it takes over.
Try it
npx playwright install chromium, then add the MCP server with TYPESAFE_API_KEY or OPENROUTER_API_KEY.
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.
