The resolve_login_shell_path() function spawns a shell with -l -i -c to
recover the user's PATH. The -i (interactive) flag causes zsh to call
tcsetpgrp(), stealing the foreground process group from the parent goose
process. When rustyline later calls tcsetattr to enter raw mode, goose
is in a background process group and receives SIGTTOU, suspending the
CLI immediately after the banner prints.
Since commit b7aea3dc9 ('warm shell PATH lookup during session init'),
this shell is spawned eagerly at startup rather than lazily on first
shell command, making the race condition much more likely to trigger.
The -l (login) flag alone is sufficient to source .zprofile/.bash_profile
where PATH modifications are typically configured.

🦆 goose has moved! This project has moved from
block/gooseto the Agentic AI Foundation (AAIF) at the Linux Foundation. Some links and references are still being updated — please bear with us during the transition.
goose
your native open source AI agent — desktop app, CLI, and API — for code, workflows, and everything in between
goose is a general-purpose AI agent that runs on your machine. Not just for code — use it for research, writing, automation, data analysis, or anything you need to get done.
A native desktop app for macOS, Linux, and Windows. A full CLI for terminal workflows. An API to embed it anywhere. Built in Rust for performance and portability.
goose works with 15+ providers — Anthropic, OpenAI, Google, Ollama, OpenRouter, Azure, Bedrock, and more. Use API keys or your existing Claude, ChatGPT, or Gemini subscriptions via ACP. Connect to 70+ extensions via the Model Context Protocol open standard.
goose is part of the Agentic AI Foundation (AAIF) at the Linux Foundation.

Why did the developer choose goose as their AI agent?
Because it always helps them "migrate" their code to production! 🚀
