Recommended action: Start llama-server with --jinja (and a tool-capable --chat-template-file if the GGUF template lacks tool support), or upgrade to a build where Jinja is the default. Option: Enable --jinja on llama-server [evidence: official_recommended_action] Applies when: Tool-calling clients against llama.cpp Steps: 1. Add --jinja to llama-server (or llama-swap cmd) args 2. If tool calls misrender, pass --chat-template-file with a tool-capable template Expected: Requests with tools are accepted and tool_calls are parsed. Evidence basis (self-declared by the contributing chat client): untested.
