Mcgyvr
Offload one scoped coding task to mcgyvr, a CLI that runs it on deterministic tools, local models or API models and keeps only what its deterministic gate accepts. Use it when a change has one target and a way to judge it (format, import sort, lint fix, rename, docstring, type annotations, a function, its tests, a bug fix): author a task contract, validate it, run it, read the result file, replan from the findings. It never loads itself; invoke it with /mcgyvr. The schema below is the only contract vocabulary.
