From c437c6bff6285695aefbfbc2d0e892c9e7a47642 Mon Sep 17 00:00:00 2001 From: root Date: Tue, 29 Sep 2026 01:27:48 +0800 Subject: [PATCH] feat(browser): vision automation loop with screenshots, coordinate actions and bounded challenge solving MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - browser.screenshot returns the page as an image content block (≤1280px wide, JPEG quality configurable) for vision-capable upstreams; non-vision upstreams get a redacted text snapshot. Login pages / password fields are marked sensitive and withheld unless a browser.sensitive_screenshot grant exists and allowSensitive is passed. - browser.click_at / type_at / scroll / wait act in screenshot pixels; the server converts via viewport/DPR, requires automation control and an allowlisted host, and writes a thumbnail evidence file (DATA_DIR/tmp/evidence) referenced from agent_run_event. - browser.solve_challenge runs a bounded child agent_run (vision caps only, maxSteps ≤ 12, budget), judges success from page facts, stops immediately on 2FA / SMS / device confirmation, and otherwise moves the session to waiting with evidence and a takeover link. - PiAgentRuntime passes modelImage outputs as pi-ai image content when model.input has image; the ledger never stores image data; coordinate actions use per-invocation idempotency keys. - Tests: image codec, runtime image content, E14 e2e (login solved, 2FA stop, step limit, sensitive withheld). Real camofox 1.17.0 check on example.com recorded in the runbook.
