Playwright provides auto-waiting plus frame, open-shadow-root, upload, select, drag/drop, keyboard, and coordinate interaction. The agent reads compact DOM snapshots and acts through refs; screenshots and coordinates are fallbacks. It never reads cookies or profile storage directly. + +The service uses Clearcote and Playwright through their public APIs; no OpenAI browser-extension code or artifacts are included. ### Updates diff --git a/capabilities/skills/chromium-browser/SKILL.md b/capabilities/skills/chromium-browser/SKILL.md index 2b05ab5..0e92776 100644 --- a/capabilities/skills/chromium-browser/SKILL.md +++ b/capabilities/skills/chromium-browser/SKILL.md @@ -3,12 +3,12 @@ name: chromium-browser description: Use Wirebot's local Chromium for opening, browsing, inspecting, navigating, or interacting with websites in server environments. --- -# Chromium Browser +# Playwright Browser -Use the bundled semantic browser CLI.

Chromium's process sandbox stays enabled; the included Compose file applies [Playwright's Docker seccomp profile](https://github.com/microsoft/playwright/blob/75d6aebfebeb9af66423390fb957e86ef38652be/utils/docker/seccomp_profile.json) so it can create its isolated namespaces. If you start Wirebot with `docker run` instead, pass `--security-opt seccomp=/path/to/docker/playwright.seccomp`. The image pins Patchright, and Debian supplies security-updated Chromium for both amd64 and ARM64 whenever the image is rebuilt. The skill follows Codex's semantic-first lifecycle: each task gets an isolated named session, reads compact page snapshots, acts through element refs, and closes the session when finished unless its browser is a requested deliverable. Patchright supplies auto-waiting plus frames, shadow DOM, uploads, selects, drag/drop, dialogs, keyboard, coordinate interaction, and a visual session dashboard. Screenshots and coordinates remain fallbacks. The skill never reads cookies or profile storage directly. diff --git a/capabilities/skills/chromium-browser/cli.config.json b/capabilities/skills/chromium-browser/cli.config.json index
