Execute natural-language E2E test instructions against the page Alethia is currently driving. Returns per-step results, policy audit records, and a SHA-256 integrity hash. Destructive actions (delete, purchase, transfer, etc.) are blocked unconditionally. Sensitive input (passwords, credit cards, SSN) is blocked unless allowSensitiveInput is true. ~13 ms per step on average.

Compile natural-language test instructions to Alethia Action IR text, without executing anything. Returns the compiled IR, per-line confidence scores (0-1), and warnings for any lines the compiler could not parse. Use this to preview what tell() will run, debug coverage gaps, or generate reproducible IR scripts for CI pipelines.

Health and identity probe. Returns runtime version, the default VITRON-EA1 policy profile in effect, kill switch state, driver statistics (queued plans, run count, audit count), the current page domain, and runtime capabilities. Use this for liveness checks before sending tell() calls, and to verify the runtime is in a known-good state at the start of an agent loop.

Halt all current and queued automation immediately. The per-step VITRON-EA1 policy gate stays armed; subsequent tell() calls will be blocked with reason KILL_SWITCH_ACTIVE until reset. Use this when an agent appears to be acting unsafely, when human review is required, or to enforce a hard boundary at the end of a controlled test run.

Capture a PNG screenshot of the current page and return it as a base64-encoded image. Use this to visually verify what the browser is showing after running test steps with alethia_tell.

Evaluate a JavaScript expression in the page under test and return the result. Runs in the context of the navigated page, not the Alethia host UI. Use this for queries the NLP compiler cannot express — counting elements, reading computed styles, checking localStorage, or any DOM inspection that needs raw JS.

Run a WCAG 2.1 AA accessibility audit on the current page, powered by axe-core. Checks alt text, form labels, keyboard access, color contrast, ARIA usage, heading structure, and the rest of the axe-core ruleset — not a fixed checklist. Call after navigating with alethia_tell. Returns findings with rule IDs, impact levels, and issue counts.

Run a NIST SP 800-53 Rev. 5 web application security controls audit on the current page. Checks 8 controls across 3 families: AC (login lockout, security banners, session timeout), IA (unmasked passwords, weak password constraints, MFA indicators), SI (input validation, error information leakage). Call after navigating with alethia_tell. Returns findings with control IDs and severity levels.

Export the full session recording as a signed evidence pack. Contains every tool call made during this session with timestamps, inputs, outputs, policy decisions, and a SHA-256 integrity hash. Use at the end of an agent loop to produce cryptographic proof of everything the agent did. Designed for compliance review and chain-of-custody.

Run multiple test flows concurrently — each against a different URL. Takes an array of test specs, spawns a browser instance per spec, runs them in parallel, and returns all results together. Use this to verify multiple pages simultaneously.

Start a local HTTP server for the built-in Alethia demo pages and return the base URL. Use this to serve demo pages on localhost so they appear in preview panels (Claude Code, VS Code, etc.). The server runs on a random available port on 127.0.0.1. Call this before alethia_tell to get a localhost URL instead of a file:// path. Returns the base URL and a list of available demo pages.

Navigate to a URL, scan the page for interactive elements (headings, buttons, forms, links, destructive actions), and generate a candidate NLP test suite ready to pass to alethia_tell. Returns an array of plain-English test blocks, including an auto-generated "EA1 Safety Gate Verification" block that uses "expect block: " for every destructive control on the page. Use this to bootstrap test coverage for a new page or to discover what the safety gate should be watching.

Navigate to a URL, discover every destructive / write-high action on the page, and verify the VITRON-EA1 policy gate blocks each one. Returns a per-action report with block/allow status. This is the automated policy-verification primitive — proves the safety gate works on a real page without the agent or human having to click each destructive button manually. Use it as a compliance check before releasing an agent-driven workflow against a customer environment.

Show the Alethia cockpit window — the oversight surface where the target app is driven and each step is highlighted live (green = pass, blue = type, red = EA1 block). Use this to pop the UI into view during a headless-launched session for demos, review, or partner walkthroughs.

Hide the Alethia cockpit window. The runtime keeps running and continues to accept tool calls; only the visible window is dismissed.
