Google Open-Sources Elephant-Goldfish Model Plugin

EGM’s strongest idea is separating architectural intent from implementation and deliberately giving reviewers less context to expose blind spots. It adds valuable discipline to AI coding, though teams must decide whether the extra review stages justify the additional time and model usage.

• –Elephant sessions retain repository context to develop requirements, trade-offs, and implementation plans.
• –Goldfish agents independently test specs for ambiguity, missing dependencies, edge cases, and readiness.
• –The workflow turns “prompt and patch” coding into a repeatable spec-driven engineering process.
• –Codex, Claude Code, Antigravity, and other harnesses make the approach portable across coding-agent ecosystems.
• –Drift reports help detect when production code diverges from its approved design.
