🎯 What The Plugin Does

Active Assistance (Not Passive Monitoring)

The plugin actively helps CoderAgent by:

1. Showing toast notifications when CoderAgent starts
2. Validating output after CoderAgent completes
3. Displaying success/warning toasts based on checks
4. Providing session summaries at the end

Three Key Hooks

Hook	When	Action
tool.execute.before	CoderAgent starts	Shows monitoring toast
tool.execute.after	CoderAgent completes	Validates checks, shows result toast
session.idle	Session ends	Shows completion toast

---

📝 Notes

Why No Session Log Analysis?

The session ses_3da57e5cdffe5u3zhBoacHEbMG was from before the plugin was installed. To see the plugin in action:

1. Restart OpenCode (loads plugin)
2. Run a new CoderAgent task
3. Watch for toast notifications
4. Check console output

Plugin Persistence

The plugin files are now in:

.opencode/plugins/coder-verification/

These are project-level plugins and will persist with the repository.

The CoderAgent Assistant Plugin is complete and ready to use!

It will now actively help CoderAgent by:

• ✅ Showing reminders via toast notifications
• ✅ Validating output after completion
• ✅ Providing clear visual feedback
• ✅ Working with all CoderAgent invocations
