fix(headless): derive ephemeral tools from conversation model by letta-integration[bot] · Pull Request #3871 · letta-ai/letta-code

letta-integration · 2026-08-16T23:32:25Z

Summary

resolve the initial ephemeral toolset through the authoritative conversation model, using the same shared scope path as agent-backed conversations
remove the ephemeral-only projected-model override
verify exact toolset and tool-name parity with agent-backed conversations for OpenAI, Anthropic, and Gemini models

This follows #3817 and prevents the agent-free path from drifting into separate model/toolset behavior.
