Run a controlled matrix comparison of approaches over a set of tasks — e.g. the kitsoki pipeline vs a naive single prompt, across a harness/model candidate matrix — scoring outcome, compliance, cost, and time, adjudicating implementation-coupled oracles, then regenerating a report + slidey deck offline with zero re-spend. Use when the user says "bake-off", "compare kitsoki vs single-prompt", "run a matrix comparison", "which model/harness is best at X", "kitsoki-vs-X study", "benchmark these approaches on these tasks", or wants an evidence-backed, cost-accounted comparison of contenders across a model grid. Generalises tools/bugfix-bakeoff (the reference implementation).
