The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

call_qtmodel_api ~263
Call a qtmodel API method not covered by a curated tool (调用 qtmodel 长尾 API). ESCAPE HATCH — prefer a dedicated tool when one exists. Discover the real signature with list_qtmodel_api first. Arguments are validated against the real signature before dispatch, so a wrong parameter name fails fast with the correct signature rather than corrupting the model. Destructive/long-running methods (initial 清空模型, do_solve 求解) are blocked here — use initialize_model / run_analysis instead. （清空模型、求解等危险或长耗时操作已禁止经此调用，请用对应专用工具。） Args: api_object: Database object (数据库对象): "mdb", "odb", "cdb" method: Exact method name (精确方法名), e.g. "add_spectrum_function" kwargs: Keyword arguments as a dict, matching the real signature (与真实签名一致的关键字参数字典) Example: call_qtmodel_api("mdb", "add_tendon_group", {"name": "钢束组1"})

check_qiaotong_connection ~325
Diagnose the connection to QiaoTong software (诊断桥通软件连接状态). CALL THIS FIRST when any tool reports the backend is unavailable. It distinguishes the three failure modes, which need different fixes: （任一工具报后端不可用时先调用本工具，它区分三种需要不同处置的状态） - connected (已连接): ready to model. - version_mismatch (版本不匹配): the QiaoTong API version and the installed qtmodel differ. qtmodel pins an exact version, so the user must upgrade QiaoTong (or install a matching qtmodel). （桥通与 qtmodel 版本必须精确一致，需升级桥通软件） - software_not_running (软件未启动): start QiaoTong and wait for the main window, then retry. （启动桥通并等待主界面加载） Returns the status, a human-readable message, the recommended action, and the client/server versions involved. IMPORTANT: when connecting through a port forward (e.g. an SSH tunnel to QiaoTong on another machine), the URL host must be `localhost`, not `127.0.0.1`. Windows HTTP.sys validates the Host header and rejects the bare IP with "400 Invalid Hostname" even though the port is reachable. （经端口转发访问时必须用 localhost；Windows HTTP.sys 会以 400 Invalid Hostname 拒绝 127.0.0.1 的 Host 头）
