# hello — example zut extension (Go) A minimal example showing how to register slash commands with the `ext` SDK. ## Build ```bash cd examples/extensions/hello go build -o hello . ``` ## Install ```bash # from this directory zut ext install . ``` This copies the directory (manifest + binary) into `$ZUT_HOME/extensions/hello/`. zut picks it up the next time you launch the TUI. ## Use In zut, type: - `/hello` — agent greets you - `/hello ` — agent greets `` - `/summon` — extension pushes a one-shot notice to the chat ## See also - `packages/agent/ext` — Go SDK - `docs/extensions.md` — protocol reference for any-language extensions
