DeepSeek Harness (DSH) plugin: a live iOS Simulator — and a USB-connected iPhone — inside the conversation. 22 agent tools for booting, building, driving the UI by accessibility identity, OCR text or list rows, plus a streaming sidebar panel you can tap and drag on.
DeepSeek Harness plugin for Android — build, run, and interact with a live emulator or USB device stream inside a conversation, driven entirely through adb.
DeepSeek Harness plugin that does QA: an agent explores your app like a real user and leaves evidence, then the explored path is exported as a deterministic replay scenario you run every release. Orchestrates the browser, macOS desktop, iOS and Android drivers — never a false green.
Design taste your agent can be held to — a design-system skill plus design_audit, which measures the rendered page (type scale, contrast, spacing grid, palette drift) instead of trusting it looked right.
ADHD-friendly output shaping for DeepSeek Harness: one system-prompt section with adhd_on/adhd_off/adhd_status tools, persisted across restarts. Inspired by ayghri/i-have-adhd (MIT).
