audit_urlYou want the full audit pipeline against one URL — agent loop, scoring, JSON + HTML report.explore_urlYou want a quick autonomous run with a free-form goal; no scenario YAML needed.seeYou want to look at a URL once and get back DOM summary + screenshot + console errors + an optional natural-language note. 0 LLM cost when `goal` is omitted.actYou want to drive an action sequence (click / fill / scroll / screenshot / natural-language `act` / vision `note`) and get back per-step status + final DOM + screenshot.extractYou want a typed payload back from a URL — pricing tiers, feature lists, FAQ entries — shaped exactly the way you asked for. Hand the tool a JSON Schema; get back `data` matching it plus DOM / console / screenshot.judgeYou want a rubric-driven critique of one URL — aesthetic polish, dark-pattern risk, or any custom rubric. Returns per-criterion scores (0..10) + severity-graded findings with on-screen locations. 1 vision call.compareYou want an A/B comparison of two URLs against the same rubric. Default `double_blind` mode judges each side independently then synthesises a comparison (3 vision calls, free of anchoring bias). `fast` mode is 1 call (cheaper, anchored).list_personasDiscover which personas are installed in a project.list_scenariosDiscover which scenarios are installed in a project.list_capabilitiesSelf-describe the server: every shipped tool with kind / cacheability / static cost band / side-effects / dependency declarations, plus the public env-var table and live result-cache state. Pure introspection — call it once on first connect to plan the rest of your session.calibrate_criticRun the critic calibration gate against labeled fixtures (returns pass/fail + agreement metrics).get_last_reportRead the most recent audit's summary JSON from the local history DB.
