   OpenCode runs this command on every startup:
   bun add --force --exact --cwd ~/.cache/opencode @aws-sdk/credential-providers@latest

   This causes:

   • --force bypasses the local cache
   • @latest requires npm registry lookup
   • ~30 second delay even with packages already installed

   Log Evidence

   INFO +0ms service=bun cmd=["opencode","add","--force","--exact","--cwd","/home/user/.cache/opencode","@aws-sdk/credential-providers@latest"]
   INFO +29183ms service=bun code=143 stdout=bun add v1.3.5 ... stderr=Resolving dependencies

   Root Cause

   OpenCode's provider detection sees AWS_PROFILE → assumes user wants AWS Bedrock → installs AWS SDK with --force flag on every startup, defeating caching.

   Workaround

   AWS_PROFILE= opencode

   Experienced extremely slow starts after trying OpenCode for the first time. Attempted this fix by clearing AWS_PROFILE and resolved the issue for me.
