Summary

Fixed duplicate call to loadAgents during /agents reload and similar events.
Fixed Streaming.

Details

Removed the call to initialize() in onAgentsRefreshed in packages/core/src/config/config.ts. Previously, this handler called initialize(), which in turn called loadAgents() again. Since reload() already calls loadAgents(), this was redundant and caused "already loaded" errors for remote agents in A2AClientManager.

This issue was introduced in PR #24489 during the subagent tool refactoring.

Related Issues

Fixes the issue where /agents reload throws 'already loaded' errors for remote agents.

How to Validate

  1. Run /agents reload in the CLI.
  2. Verify that no "already loaded" errors are thrown for remote agents.

Pre-Merge Checklist

  • Updated relevant documentation and README (if needed)
  • Added/updated tests (if needed)
  • Noted breaking changes (if any)
  • Validated on required platforms/methods:
    • MacOS
      • npm run

Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request addresses an issue where agent reloading caused redundant initialization calls, leading to errors in the A2AClientManager. By removing the unnecessary call in the configuration handler, the system now correctly manages agent states during refresh events without triggering duplicate load operations.

Highlights

  • Redundant Initialization: Removed the call to agentRegistry.initialize() within the onAgentsRefreshed handler to eliminate redundant agent loading.
  • Error Resolution: Fixed the 'already loaded' errors triggered during agent reload operations by preventing duplicate initialization cycles.

Replaced the hacky invocation of the private `onAgentsRefreshed`
method with the correct public API `getAgentRegistry().reload()` in
the config-agents-reload tests. This aligns the tests with the
intended architecture where the registry manages its own state and
emits an event upon reload, which the Config then reacts to.
