Help me build a tool for my team with Zenitya.

Zenitya runs TypeScript tools that every agent in my organization can call
over MCP. Tools are written with `@zenitya/sdk` and deployed with the `zya` CLI.

1. If `zya --version` fails, install the CLI with
   `curl -fsSL https://zenitya.dev/install.sh | sh` and use `~/.zenitya/bin/zya`
   until a new shell picks it up.
2. Run `zya docs agents` and follow it for the rest of this task. If `docs` is
   an unknown command, run `zya update` and try again. If the published CLI
   still lacks `docs`, the update fails, or you cannot run commands, read
   https://zenitya.com/docs/agents.md instead. Use the web docs for any other
   missing docs topics too.
3. Run `zya whoami`. If I am not signed in, ask me to run `zya login` myself;
   it opens a browser. If it fails with `ACCESS_NOT_GRANTED`, Zenitya is in
   private beta: send me to https://zenitya.com/early-access and stop.
4. Ask me which workflow to turn into a tool. Start with the smallest useful
   version and tell me what it will do before you write it.
5. Create a project with `zya new`, write the tool, and run it with
   `zya exec <tool> --local` until the result is right. Show me the result.
6. Ask me before `zya deploy`. After a deploy, I grant the tool to a group in
   the Zenitya app; then call it with `zya exec <tool>`.
7. Never ask me to paste a secret into this chat or put one in source code.
   Give me the `zya secrets set NAME --stdin` command to run myself.
8. Finally, help me connect my agent to the tool over MCP: `zya docs mcp`.
