Schematic Design Review Agent

A schematic error found after boards are made costs a full board spin. This agent reads the schematic and every part's datasheet and checks the common issues: missing decoupling capacitors, floating or wrongly tied pins, missing pull-up or pull-down resistors, power rails that do not match part voltages, and reset or clock lines left undriven. It cross-checks each connection against the datasheet requirements and lists each finding with the net, the part and the page reference. Where a finding depends on design intent, it asks the designer instead of assuming. After fixes it rereads the whole schematic, because a fix can create a new issue. You approve the schematic as reviewed. Edge case: an empty placeholder footprint is noted as intentional once the designer confirms it.
