Pick a browser or desktop agent's next action by choosing among the actions actually on screen instead of inventing one. Candidates come from the accessibility tree, the task goes in instructions, and a calibrated confidence decides whether to click or hand the step back to your own model. Use when building or debugging computer use, browser automation or a web agent, or on "it clicked the wrong thing" and "how do I stop it looping".
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
# Choose the next action from what is on screen An agent that writes its own action can name a button that is not there. Make the step a choice over the page's real elements and that failure goes away: the answer indexes a list you built, and carries a calibrated probability. ## When not to use it - Steps needing reasoning the page does not show, like comparing prices across tabs. Classify the action, not the plan. - Anything irreversible: payments, deletions, sending mail. Gate those on a person, never on a number. - Fewer than about five obviously different candidates. Your own model knows already; the call is a round trip you do not need. ## 1. Candidates from the accessibility tree Snapshot it — Playwright's `page.accessibility.snapshot()`, or `Accessibility.getFullAXTree` over the DevTools Protocol — and keep the nodes a person could act on: ``` button "Add to cart" combobox "Size" value "Choose a size" link "Continue shopping" link "Sign in" textbox "Search products" ``` Turn each node into one label in the words a person would use — `click the Add to cart button`, `type into the Search products field` — plus the moves that …

How to install
mdr add mrmps/classifier-dev/computer-use-action-picker@sha256:e0163789c61e45d4The line at the top of this page pins the label git:20260919.33ae531, 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.
