jev-assert

Verifies a UI expectation semantically by asking TypeSafe's Jev model whether a user-observable outcome holds in a page's captured TEXT state (accessibility tree / page text — never a screenshot), then maps Jev's typed answer and probability onto this repo's verify-behavior receipt vocabulary (confirms, contradicts, ambiguous, null, unobtainable). Driver-agnostic: consumes text state from either the Playwright (aw-tester) or the claude-in-chrome (aw-tester-chrome) runner, so the Chrome-vs-Playwright choice is orthogonal to it. Use it for a semantic UI assertion where an exact locator or string match is brittle — "did the user see a success state", "is this the right screen". Delegates the API contract to the typesafe@typesafe-ai skill (TYPESAFE_API_KEY). Triggers on "assert semantically", "does the page show", "verify this outcome with jev", "semantic UI assertion", "jev-assert", "/jev-assert".

W011: Third-party content exposure detected (indirect prompt injection risk).

What this means

The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.

Why it was flagged

The script `scripts/jev-call.mjs` reads captured page text from a state file or stdin and sends it to the external TypeSafe API endpoint `https://api.typesafe.ai/v1/systemone` as part of its required workflow.
