mechanize

Decide whether a step currently done by AI inference should become a deterministic tool instead - check whether the output is a FUNCTION of the input (mechanize it) or requires judgement (keep AI on it), then run the counter-test before committing. Use when a model has computed, checked, or classified the same thing identically across several turns or ticks, or before scripting a step an agent currently performs by reasoning. Not for checking whether a tool can be trusted once built (verify-the-instrument), whether existing reasoning holds (sanity-check), or whether to adopt someone else's code versus write your own (adopt-or-build) - this decides whether a tool should exist here at all.
