Why: Field evidence from the dev instance - the present tool was
projected and enabled but never called, because every resident prompt
module steers 'make me a report' toward file artifacts; the tool
description carried only the component catalog, not when to use it.
Evidence: genui suite green (catalog assertion extended implicitly by
existing shape test); end-to-end model behavior verified post-deploy
in the Dev task.
Impact: Tool description text only (self-gating: description appears
only when the activation gate projects the tool).
