# Subtext Verify: Beta Tooling for Agent-Driven Verification

> Verify is Subtext's closed beta tooling — a cloud-hosted browser, proof documents, artifacts, and Sightmap integration for agent-driven UI verification.

<Warning>Verify is available to the closed beta cohort. These tools may move out of the core MCP. Join the waitlist at subtext.fullstory.com.</Warning>

Verify is the verification layer built on top of core Subtext. While the main Docs tab covers session review — replaying user sessions, attaching comments, and inspecting events — Verify adds the tooling your agent needs to actively drive a browser, produce evidence, and leave a permanent record of its work. Everything here is beta: the APIs are stable enough to build on, but the shape of this stack may change as it moves toward general availability.

## What Verify adds

Core session review lives in the main Docs tab. Verify extends that foundation with six new capability areas.

<CardGroup cols={2}>
  <Card title="Live Browser" icon="browser" href="/docs/verify/live-browser">
    A cloud-hosted browser your agent opens and controls. Every snapshot is enriched by Sightmap — semantic component names, source paths, visibility, and interactivity are surfaced automatically. Includes network and console inspection, device emulation, and the full interaction surface: click, fill, drag, upload, keypress, and more.
  </Card>

  <Card title="Artifacts" icon="cloud-arrow-up" href="/docs/verify/artifacts">
    Upload screenshots and documents to cloud storage with `artifact-upload`, then generate fresh signed URLs with `artifact-url`. Artifacts give you a durable, shareable pointer to any piece of visual or documentary evidence your agent produces.
  </Card>

  <Card title="Proof Docs" icon="file-lines" href="/docs/verify/proof-docs">
    Permanent, evidence-backed records of agent work. Open a doc with `doc-create`, attach before/after screenshots, diffs, and logs with `doc-attach`, then seal it with `doc-close`. The result is a versioned document you can read, diff, and share — a full audit trail for every change your agent makes.
  </Card>

  <Card title="Skills" icon="slash" href="/docs/verify/skills">
    Verify-specific slash commands that give your agent curated guidance without manual prompting. `/subtext:proof` drives the inner loop for capturing BEFORE/AFTER evidence. `/subtext:live`, `/subtext:sightmap`, `/subtext:tunnel`, `/subtext:docs`, and `/subtext:comments` each load the relevant tool catalog and usage patterns atomically.
  </Card>

  <Card title="Sightmap" icon="map" href="/docs/sightmap/overview">
    The same Sightmap you define for session review enriches every Live Browser snapshot. YAML files in `.sightmap/` map CSS selectors to semantic component names, source paths, and memory entries — contextual notes that appear as a **\[Guide]** block at the top of every snapshot so your agent understands the UI without reading source.
  </Card>

  <Card title="Tunnel" icon="network-wired" href="/docs/verify/tunnel">
    The cloud-hosted browser cannot reach your machine directly. The Subtext Tunnel bridges it to your localhost dev server through a reverse tunnel — a lightweight local MCP server you add to your config alongside the main Subtext server.
  </Card>
</CardGroup>

## Skills reference

The Verify slash commands load focused, atomic guidance into your agent's context on demand.

| Skill               | Type     | Purpose                                                                  |
| ------------------- | -------- | ------------------------------------------------------------------------ |
| `/subtext:proof`    | workflow | Inner loop — capture BEFORE/AFTER evidence as you make UI changes        |
| `/subtext:live`     | atomic   | Hosted browser tools (`live-*`) catalog and usage patterns               |
| `/subtext:sightmap` | atomic   | Sightmap schema and authoring guidance                                   |
| `/subtext:tunnel`   | atomic   | Reverse tunnel setup so the hosted browser can reach localhost           |
| `/subtext:docs`     | atomic   | Proof document tools (`doc-*`) and seed templates for agent work records |
| `/subtext:comments` | atomic   | Comment tools (`comment-*`) for agent-user collaboration                 |

<Note>
  Core session review tools — `review-open`, `comment-*`, `event-*`, and the rest of the session inspection surface — are documented in the main Docs tab, not here.
