The Timed 25-Foot Walk times 7.62 m from a standing start at the fastest safe pace. Instructions, normal times (about 3.7–4.4 s in healthy controls), the 6- and 8-second MS benchmarks, the 20% rule and how it differs from the 10-metre walk test.
What are the HU values of air, lung, fat and muscle on CT? We measure them on a public chest CT with pydicom instead of copying a table, and show three traps real DICOM data sets: file order, -2048 HU padding and uint16 wrap-around.
How do you give each AI agent only the MCP tools it should have? We build a small gateway in front of the official git, fetch and time servers and measure it: tool tokens down 57-69% per role, about 0.6 ms per call, and 9 of 9 out-of-policy calls refused.
How do you build an MCP server, and what does it cost? We expose YOLO11 detection as MCP tools with the official Python SDK 2.x, then measure stdio overhead (0.6 ms), cold start (1.4 s) and why a base64 image as a tool argument costs 71,000+ tokens.
