automation

automation is a skill for Claude Code, Codex from vercel-labs/native. It costs 69 tokens per session (4,141 once invoked), scanned A, original, Apache-2.0.

A guide for testing running Native SDK applications through their built-in automation server. It can inspect windows and widgets, drive real input paths, take repeatable screenshots, test the JavaScript-to-Zig bridge, and check readiness.

In plain words
What is it for?
Use it for smoke tests, continuous-integration checks with a graphical session, runtime inspection, widget interaction, screenshots, readiness checks, bridge tests, reloads, and debugging automation connections.
Why use it?
It provides repeatable runtime checks for native-rendered apps and apps that contain a WebView. It helps verify that the app starts correctly, responds to interactions, and connects its native and JavaScript parts.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

automation scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Automate Native SDK apps

Every Native SDK app embeds an automation server — native-rendered apps and WebView-shell apps alike. It works through file-based IPC in .zig-cache/native-sdk-automation/ and is intended for smoke tests, CI checks with a GUI session, and quick runtime inspection: accessibility snapshots, widget driving through the real input paths, deterministic reference-renderer screenshots, readiness/state assertions, and bridge round-trips.

Automation is not browser DOM automation. It reports runtime/window/widget state, drives retained-canvas widgets, and can ask the runtime to reload or dispatch bridge requests. For DOM testing of the optional WebView path, use the frontend framework's tests or a browser automation tool against the dev server.

What automation can verify

  • An automation-enabled app started and published ready=true.
  • The runtime loaded the expected app name, source kind, and window metadata.
  • The main window exists and is focused/open.
  • The JavaScript-to-Zig bridge can round-trip a request through native automate bridge.
  • Builtin window/WebView commands work when exercised by a smoke test.
  • Reload requests are accepted by the runtime.
  • Real pixels of retained-canvas (gpu_surface) views: native automate screenshot <view-label> renders the view's current canvas frame through the deterministic CPU reference renderer and writes a PNG artifact. Two captures of an unchanged scene are byte-identical, so screenshots can back golden-image or "did the UI change" checks.

What automation cannot verify

  • Screenshots of WebView content. screenshot covers gpu_surface canvas views only; there is no DOM/WebView pixel capture.
  • Arbitrary DOM queries and clicks.
  • Browser network assertions.

Prerequisites

Build/run an app with automation enabled. Generated examples usually expose -Dautomation=true:

zig build run -Dplatform=macos -Dautomation=true

Repository examples may have specialized steps:

zig build run-webview -Dplatform=macos -Dautomation=true
zig build test-webview-smoke -Dplatform=macos

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

automation is a skill published in the GitHub repository vercel-labs/native (7,625 stars, last pushed yesterday), licensed Apache-2.0. It adds 69 tokens to every session and 4,141 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
