This project is a fork of computer-user, Copyright (c) 2026 jing-hy,
licensed under the MIT License (https://github.com/jing-hy/computer-user).

The upstream project established the design this fork builds on. The following
parts originate there and are used under the terms of its MIT License:

  · src/capture.ps1        DPI-aware multi-monitor screenshot via
                           System.Windows.Forms / System.Drawing.
                           Copied unmodified.

  · src/input.ps1          Mouse and keyboard automation via Win32 SendInput,
                           including the embedded C# interop type, the virtual-key
                           table, Unicode character injection, and the drag
                           interpolation. Copied unmodified.

  · src/ps.ts              The PowerShell runner protocol: a base64 JSON payload
                           argument, one JSON object on stdout carrying a boolean
                           `ok`, and the backward scan for that object.
                           Ported from upstream src/ps.js.

  · src/output-guard.ts    The LLM output guard: the fake-tool-call patterns, the
                           fingerprint-counted "reject once, then pass" rule, and
                           the buffer window. Ported from upstream
                           src/output-guard.js.

  · src/tools.ts           The computer_* tool set and its descriptions, the
                           four-mode gate (disabled / readonly / manual / auto),
                           the /computer approval semantics, the coordinate
                           system (virtual-screen pixels with virtual_offset),
                           and the text rendering of tool results. Extended in
                           this fork; see below.

  · src/config.ts          The settings namespace, most keys, and their
                           descriptions. Extended in this fork.

  · src/index.ts           The /computer command, the settings registration, the
                           output-guard wiring, and the route-handling helpers
                           (json / error / body). Extended in this fork.

  · client (settings card) The idea of a 电脑操作 settings section with a mode
                           dropdown. Rewritten in this fork against the plugin's
                           own settings route.

  · skills/computer-use.md The look-act-verify workflow, the window-locating
                           guidance, and the DPI-awareness warning. Adapted in
                           this fork for the virtual-desktop mode.

Added by this fork (dsh-plugin-computer-user), not present upstream:

  · src/session.ts         VirtualSession: the shared board the panel renders —
                           frames, overlays, the virtual cursor, and the user's
                           instruction queue.

  · src/ports.ts           The DesktopPort seam and its two implementations
                           (real SendInput vs virtual recording), which is what
                           makes `link_mode` a single swap rather than a branch
                           in every tool.

  · src/geometry.ts        The screen ↔ frame ↔ panel coordinate transforms,
                           shared by the host and the browser half.

  · src/client.tsx         The right-sidebar snapshot panel: live frame, virtual
                           pointer and trail, click ripples, typed-text and key
                           labels, user hint pins, zoom / pan / follow, the
                           link-mode badge and switch, and the settings card.

  · computer_get_vision    Reports the coordinate map and the user's pending
                           instructions to the model.

  · computer_set_link_mode Switches the action target, gated like
                           computer_set_mode.

  · link_mode             The virtual / real setting itself, defaulting to
                           virtual.

  · The capture loop, the /api/computer-user routes (status, frame, vision,
    events, capture, hint, hint-clear, settings), and the SSE stream with replay.
