描述

Description

After running rtk init -g --opencode (and also rtk init -g), the command rtk gain still shows this warning:

[warn] No hook installed — run rtk init -g for automatic token savings

This warning appears every time even though:

  • The OpenCode plugin has been installed successfully (rtk init --show shows [ok] OpenCode: plugin installed)
  • rtk --version works correctly (currently v0.34.1)
  • rtk gain successfully shows token savings statistics
  • Cursor hook is also installed and working

Steps to Reproduce

  1. Install RTK on Windows (rtk-x86_64-pc-windows-msvc.zip)
  2. Add C:\rtk to PATH
  3. Run rtk init -g --opencode
  4. Restart OpenCode
  5. Run rtk gain

→ Warning still appears.

Expected Behavior

rtk gain should recognize that the OpenCode plugin is installed and not show the "No hook installed" warning (or show a more accurate message for OpenCode/Windows).

Actual Behavior

The warning persists, which is confusing even though token savings are working and the plugin is active.

Environment

  • OS: Windows 11
  • RTK Version: 0.34.1
  • Tool: OpenCode (with custom plugin rtk.ts)
  • Other hooks: Cursor hook also installed

Additional Context

According to the troubleshooting docs, OpenCode uses a custom tool.execute.before plugin instead of native Unix-style hooks. The detection logic in rtk gain seems to only check for native hooks, causing this misleading warning on Windows.

It would be great if RTK could:

  • Better detect OpenCode plugin installation on Windows, or
  • Show a more specific message like "OpenCode plugin installed (native hook not available on Windows)" when the plugin is present.

Thanks!

研究方向
Investigate the hook detection logic in the rtk gain command, likely in src/commands/gain.rs or similar. Look for where the 'No hook installed' warning is emitted. The OpenCode plugin uses a custom `tool.execute.before` plugin rather than native hooks, so detection should check for that. Examine the method used to verify OpenCode installation on Windows. The issue also suggests a more specific message. Look at the existing plugin detection code and consider adding a check for OpenCode's specific plugin mechanism.
