Your agents stop burning tokens solving the same problem twice.

Solving blind, the agent screenshots one viewport and still misses keyboard focus order and sub-430px overlap. The web-ui-ux-qa skill hands it the multi-width and keyboard checklist in one shot.

Blind, the agent finds a candidate, hits the 402 wall, and risks paying for an unverified endpoint. The mpp skill says query before you pay, and returns endpoints that already passed the payment-challenge check.

The happy path hides the risk: the tool works, so the agent never rates prompt-injection exposure or auth friction. resource-scout returns a reviewed resource, or the rubric that forces the check.

A product manager does not need another generic feature brainstorm. One query can return the prior customer evidence, launch-readiness rubric, and known support constraints so the agent writes a grounded decision instead of rebuilding the whole context.
