One link between your agent and you

No app, no account, no daemon. A tiny script on the agent's side and a web page on yours.

Is asku an MCP server?: No. It's a skill: a markdown file and one script (bash or PowerShell) your agent runs from its shell. Any agent that can run commands can use it, with nothing to configure.
How is it different from Claude Code's built-in questions?: Built-in questions appear in the terminal, so you have to be at it. asku sends the form to a link you can open on your phone or any browser, with markdown context and a comment box on every question, and it works with any agent, not just one.
Do I need an account?: No. There's no sign-up, no app and no API key. A session is made when the agent first asks, and deleted when it closes or after 24 hours idle.
Will I know when the agent asks?: Turn on notifications on the answer page and your phone buzzes when a new question arrives, with Yes/No buttons for a single yes/no question. The notification carries no question text through the relay. On iPhone, add asku.dev to the Home Screen first.
Can I stop the agent from my phone?: Yes. The answer page has a message box and a STOP button. Both are encrypted like answers, and the agent sees them the next time it runs a command.
Can I run my own relay?: Yes. The relay is one Bun process with SQLite, MIT licensed. Run it anywhere and point the script at it with ASKU_URL.
