-Check out the configuration reference at https://huggingface.co/docs/hub/spaces-config-reference
+MIS 752 Lab 6, Week 6 (Function / Tool Calling). `qwen2.5:3b-instruct` on `ollama` was given `2` Python tools (forecast_ed_arrivals, get_drug_info) and asked a formulary question. `data/` holds the trace stage by stage (`trace_stages.csv`), the deliverable as plain text (`the_trace.txt`), the four-question tools-on/tools-off grounding sweep, the per-turn token envelope, the tool registry, and this lab's registry rendered as an MCP `tools/list` response (`mcp_tools_list.json`, protocol 2026-07-28).
+
+**Every drug in this lab is invented.** The formulary is a teaching stub; no dosing information appears anywhere and nothing here is clinical guidance.
+
+**Your ~150-word takeaways go here** -- edit this README on huggingface.co. Cover: which tool-calling path your model actually used and how often the native one failed, what the tools-off answer did when it had no way to look anything up, what the prompt-based fallback cost you in tokens, and where this exact pattern shows up outside healthcare.

MCP -- the Model Context Protocol -- is a standardised PROTOCOL for exposing tools in the first place, so a tool written once can be discovered and called by any MCP-speaking client instead of being re-wired into every application by hand. It is MIT-licensed, developed in the public, and runs over JSON-RPC 2.0: a server advertises tools/list (alongside resources/list and prompts/list) and a client invokes tools/call. The schema revision used here is 2026-07-28.
+
+In one sentence: tool calling is how a model ASKS for a function; MCP is a standard way to OFFER it one.
+
+This page does not come from an MCP server. The lab teaches the underlying mechanism -- the part that is identical whether the schema arrives in a tools= parameter or in a tools/list response -- and out/mcp_tools_list.json renders this lab&#x27;s own registry in MCP&#x27;s envelope so you can see that the two carry the same information.</div><h2>How this was measured</h2><div class="prose">Backend: ollama; model: qwen2.5:3b-instruct; Ollama 0.35.1. Every call went through one function at temperature 0.0 with max_tokens 2000, and every response was cached to lab06_cache.json so re-running a cell never spends a second call.
+
+Both tool-calling paths are implemented: the native OpenAI-format tools= parameter with tool_calls parsed off the response, and a prompt-based strict-JSON protocol that works with any model. The loop tries native first and, if the model emits no usable tool call on turn one, retries the same question on the prompt path and records that it did. path_used in every table above says which one produced the result.
+
+Grounding is a keyword rubric over each question&#x27;s key_facts -- strings that could only have come from a tool. Two corrections keep it honest: any key fact that already appears in its own question is dropped from the denominator, because the model can copy it out of the prompt without looking anything up; and matching tolerates up to three words in between, so a correct answer phrased differently is not scored zero. Every loosely matched point is listed next to the score. It is still a first pass, not a clinical gold standard.
+
+Separately, every tools-off answer is checked for NARRATED tool results -- phrases like &#x27;tool result:&#x27; or &#x27;the lookup returned&#x27; produced when no tool was available. A keyword refusal-detector reads an invented &#x27;no record found&#x27; as honest; only the trace, which has no tool_result stage, can tell the two apart. Where that happened it is named above rather than scored as good behaviour.
+
+ALL DRUG DATA IS INVENTED. The 6 drugs in this formulary do not exist; their classes, tiers, interaction flags and monitoring labels were written for a teaching stub, and every tool result says so in a warning field. There is no dosing information anywhere in this lab. Nothing here is clinical guidance and no model here is cleared for clinical use.
+
+Numbers are from one run and will vary; the pattern is the finding, not the digits.</div>
