+{#-
+  Roka tool-calling chat template — Llama-3 header format + Hermes-style <tool_call> parsing.
+
+  Compatible with llama.cpp's Hermes-2-Pro output parser (detected by the literal
+  "<tool_call>" string in this template source). Uses Kara-Kumru's Llama-3 special
+  tokens: <|start_header_id|>, <|end_header_id|>, <|eot_id|>.
+
+  Design notes:
+    - The model was fine-tuned with an exact Turkish system prompt from
+      `training/tools.py::get_system_prompt()`. That prompt already contains the
+      tool schemas and calling conventions. We therefore DO NOT synthesize a
+      generic Hermes-English tool block from `tools=[...]` — doing so made the
+      model go meta / mis-route, because it never saw that format in training.
+    - Callers should pass the training system prompt via `messages[0]` (role=system).
+      Any `tools=[...]` parameter is accepted but ignored when building the prompt;
+      its only job is to let llama.cpp expose the parsed result via OpenAI's
+      `tool_calls` field.
+    - The literal string "<tool_call>" below (inside a comment hint) is what
+      llama.cpp uses to detect Hermes-2-Pro output format: do not remove it.
+
+  Format hint for llama.cpp detector: the assistant wraps tool calls as
+  <tool_call>{"name": "...", "arguments": {...}}</tool_call>.
