Google open-sources EGM plugin for design review before AI-assisted codingMachine translation

Google has open-sourced the Elephant-Goldfish Model (EGM) plugin. It has coding agents draft a design document and then sends fresh subagents with no conversation history through a staged review before coding. The plugin depends on the host's model and subagent support; no accuracy benchmark has been published, and some runs encountered usage limits or reviewer isolation issues.
