Use the owned Stagehand Chrome for model-backed act and extract instructions.
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
Model-backed `BrowserInstruct` `act`/`extract` require the observed `lane = "stagehand"` and this installation's selected `stagehand` Exact Output. They do not move an existing Gecko or live tab to Chrome. Availability depends on the configured Chrome and the host model route.
Read the whole file at its exact version.
How to install
mdr add jeong-sik/masc/browser-stagehand@sha256:9e1f9fbac954aaa9The line at the top of this page pins the label git:20261027.4fe0239, 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.
