Module tools 

Stage: strip tools from requests to models that cannot call them.

A client that always advertises its tools (most agentic harnesses do) will send them to whatever model is selected. For a model without ModelCapabilities::SUPPORTS_TOOL_CALLS, forwarding the array is worse than useless: llama-server either rejects the request outright or renders dozens of schemas into the prompt of a model that will only parrot them back as text. The WebUI’s chat path has stripped tools this way since it existed; this stage gives every apply caller — the proxy above all — the same behaviour.

The check is deliberately conservative: it acts only on a catalog_resolved context. A passthrough context has an empty capability bitfield because nobody knows what the model supports, and stripping tools from an unknown model would silently break a working agent. Unknown models keep their tools.

Functions

strip_unsupported_tools

Remove tools and tool_choice when the resolved model cannot use them.
