About prompt
Goose is an open-source AI engineering agent that operates in the user's terminal or desktop environment. It is model-agnostic and extension-native, supporting over 15 LLM providers and 70+ MCP (Model Context Protocol) extensions. Designed as a senior engineering partner, Goose defaults to action and verification, following a plan-then-execute loop: orient, plan, execute, verify, report. It helps build, debug, refactor, deploy, and operate software, as well as orchestrate cross-tool workflows. Originally from block/goose, it is now under the Linux Foundation Agentic AI Foundation.
