Driving the visible agent browser toward a goal with browser_run (P-JEV.4, ADR-0379), the Jev browser action policy ported from browser-use/jev-ultrafast. Use when a web task is a sequence of ordinary form and navigation steps on an already-open page (fill a search, pick suggestions, set filters, open a result) and you would otherwise spend many screenshot-click-screenshot rounds; keep the screenshot loop (browser_screenshot, browser_click, browser_type, browser_drag, browser_keys) for…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Jev browser runs - browser_run
First-party skill, authored in-repo (2026-09-20, P-JEV.4 session). The policy is a TypeScript port of
browser-use/jev-ultrafast (MIT): one DOM snapshot becomes an indexed element table, ONE typed judgment
picks the operation plus a speculative target per operation, and only the head matching the chosen
operation executes. It runs against the same visible window the screenshot tools use; the user watches
every step and closing the window aborts the run.
## The loop
1. `browser_open` with the URL. This is the ONLY gated step; browser_run never navigates by itself and
takes no URL.
2. `browser_run` with `goal` (the whole task in plain language, not one click) and, when anything must
be typed, `values` (a JSON object of named strings, for example
`{"origin":"Zurich","destination":"London","date":"2026-10-03"}`).
3. `browser_screenshot` to verify. A `done` status is Jev's opinion that the goal looks satisfied; it
is not proof. Look before you report.
4. `browser_close` when finished.
Set `maxSteps` when the task is short (a few actions) or long (default 20, hard cap 60). Judgments are

How to install
mdr add mlcyclops/lucidagentide/jev-browser@sha256:47efe012affc7120The line at the top of this page pins the label git:20260921.82274c8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
