   This issue might be a duplicate of existing issues. Please check:

   • [BUG] Kimi k2.5 doesn't use the question tool #11053: [BUG] Kimi k2.5 doesn't use the question tool
   • Using Kimi K2.5 from Fireworks throws temperate related error #11134: Using Kimi K2.5 from Fireworks throws temperature related error
   • Strict JSON Schema validation fail on backends like SGLang (Missing required field in empty tool parameters) #8184: Strict JSON Schema validation fail on backends like SGLang (Missing required field in empty tool parameters)
   • LiteLLM Proxy: Vertex AI Gemini models fail for tools with empty parameters #9233: LiteLLM Proxy: Vertex AI Gemini models fail for tools with empty parameters

   The error 'JSON Schema not supported: could not understand the instance {}' appears to be related to how empty parameter schemas are handled for tools. Issues #8184 and #9233 specifically address this root cause.

   Feel free to ignore if none of these address your specific case.

   Upgrade to latest, if u are using homebrew then install:
   brew install anomalyco/tap/opencode

   Instead.

   should be fixed

   I get the same error (for about a week)
   I narrowed it down to an MCP being enabled causes the error.
   I am using OpenCode Zen too.
