Original Pull Request: https://github.com/anomalyco/opencode/pull/10875

State: open
Merged: No

Summary

Fixes #10781

When using opencode attach to connect to an already running server, the client was still performing a models.dev refresh on every connection, causing ~1 second delay. Since the server already has models cached, the attach client doesn't need to fetch them independently.

Changes

  • Skip automatic models.dev refresh when running in attach mode
  • Detect attach mode by checking process.argv for the "attach" command
  • Reduces attach startup time from ~1.2s to <100ms

Test plan

  • Run opencode serve --port 4096 to start a server
  • Run time opencode attach http://localhost:4096 --version
  • Verify the models.dev refreshing log no longer appears
  • Verify connection is instant (<100ms instead of ~1.2s)
