Elephant-Goldfish Model
Elephant-Goldfish Model is an open-source method and plugin from Google for spec-driven development with AI coding agents. A deep-context agent drafts the design, then fresh zero-context subagents stress-test that spec for gaps and wrong assumptions before any code is written, which catches problems that a single long-running agent tends to miss.

Elephant-Goldfish Model alternatives
Other coding tools in our directory. See all coding tools →
OpenHands
Open-source platform for autonomous coding agents.
opencode
Open-source terminal coding agent that works with many model providers.
Qwen Code
Open-source terminal coding agent from the Qwen team.
Sphinx
Open-source Git hook for agent-assisted coding: before code your agent wrote is pushed to a protected branch, it reads the diff and quizzes you on what the change actually does when things go wrong, and only lets the push through once you answer correctly. Works with Claude Code, Codex, Cursor and OpenCode.
PiG
PiG is a faithful Go port of Pi, the open-source terminal coding agent, first developed at Hewlett Packard Enterprise. It keeps Pi's behaviour and extension model while shipping as a single fast Go binary, so you can run the same minimal, hackable coding agent without a Node.js runtime.
rtk
A CLI proxy that sits between coding agents and your shell and trims noisy command output before it reaches the model, cutting token use on everyday commands like tests, builds and git. Free and open source, with an RTK Pro tier for teams.
