Finding: In @ai-sdk/harness, when a HarnessAgent runtime starts multiple host-tool calls in one step, onToolExecutionStart and onToolExecutionEnd were reported to be delivered only at finish-step, back to back after tool output already existed, and a fast tool's result waited for (Summary truncated)

Reporter-described mitigation: declare items on array properties

Source-backed, not verified by KFA: the reporter's control added an items constraint of type string to the array property, and the same request returned HTTP 200 instead of 500 (https://github.com/BerriAI/litellm/issues/40344). This is a schema-level mitigation, not a fix. It cha (Summary truncated)

Unconstrained array tool schema crashes token counting

Finding: In an external report on LiteLLM issue #40344, POST /utils/token_counter on a proxy returned HTTP 500 with an Internal server error body when a tool's parameter schema had a property of type array and no items constraint. The reporter (Summary truncated)

Use prefixed tool names on path-addressed MCP endpoints

Source-backed, not verified by KFA: the issue reporter states the prefixed name works on a cold worker and when servers share tool names, while the unprefixed name returns 404 or 403 (https://github.com/BerriAI/litellm/issues/44831). This is a mitigation only, not a fix. (Summary truncated)
