OpenCode plugin missing default export — plugin never loaded by plugin loader

[sacrtap]

Summary

The OpenCode plugin generated by rtk init -g --opencode exports only a named export (RtkOpenCodePlugin) but lacks a default export. OpenCode's plugin loader requires a default export to load the plugin module, so the RTK plugin is silently never loaded — the tool.execute.before hook never fires, and all bash commands execute without RTK rewriting.

Environment

• rtk version: 0.42.4
• opencode version: 1.17.8
• OS: macOS (darwin)
• Install method: Homebrew

Steps to Reproduce

1. Run rtk init -g --opencode
2. Check the generated plugin file: ~/.config/opencode/plugins/rtk.ts
3. Start OpenCode and run git status via the bash tool
4. Observe: command executes as raw git status, not rtk git status

Root Cause

OpenCode's plugin type definition (@opencode-ai/plugin) specifies:

export type PluginModule = {
    id?: string;
    server: Plugin;
    tui?: never;
};

The plugin loader expects a default export matching the Plugin type. The generated rtk.ts only has:

export const RtkOpenCodePlugin: Plugin = async ({ $ }) => { ... }
// ← missing: export default RtkOpenCodePlugin

Compare with a working plugin in the same directory (openviking-memory.ts), which has both:

export const OpenVikingMemoryPlugin = async (input: PluginInput): Promise<Hooks> => { ... }
export default OpenVikingMemoryPlugin  // ← this makes it load

Impact

• 100% of OpenCode users who install via rtk init -g --opencode have RTK silently disabled
• rtk init --show reports [ok] OpenCode: plugin installed — no warning that the plugin won't load
• Users see no errors; commands just pass through unfiltered

Fix

Add export default RtkOpenCodePlugin to the end of the generated plugin template.

The source template is likely in src/ or hooks/ — wherever rtk init --opencode generates the rtk.ts content.

Verification

After manually adding export default RtkOpenCodePlugin to ~/.config/opencode/plugins/rtk.ts and restarting OpenCode:

• git status → rewritten to rtk git status ✅
• git diff → rewritten to rtk git diff ✅
• docker ps → rewritten to rtk docker ps ✅
• make test-parallel → rewritten to rtk make test-parallel ✅
• playwright test → rewritten to rtk playwright test ✅
• sudo npm run build → rewritten to sudo rtk npm run build ✅ (transparent prefix)

Suggested Improvement

Add a runtime check in rtk init --show that verifies the plugin file contains export default. If missing, warn the user.

Adding export default RtkOpenCodePlugin to hooks/opencode/rtk.ts should fix this. The file gets embedded at build time and re-written on each rtk init -g --opencode, so it covers both fresh installs and existing setups.
