+"""Thinking/reasoning tag parsing shared across client adapters.
+
+Reasoning models wrap their chain-of-thought in delimiter tags. When the
+backend's reasoning parser is absent — or doesn't split a given model's output
+into a dedicated field — that thinking arrives inline in the message
+``content`` instead. This module is the single source of truth for detecting
+and extracting those blocks, used by the client adapters (to populate
+``ToolCall.reasoning`` and to clean ``TextResponse`` content) and by the
+prompt-rescue path in ``templates`` (to strip thinking before parsing a
+rehearsed tool call).
+
+Supported delimiters:
+  - ``[THINK]...[/THINK]``  — Mistral (Ministral Reasoning)
+  - ``<think>...</think>``  — Qwen3, DeepSeek
+
+Extend ``THINK_TAG_RE`` when adding a new model family. If a model
+library/registry is added later, move these patterns into per-model profiles
+instead of hard-coding here.
