# .fabro file extension, human gate improvements, and user workflows

## .fabro file extension

Workflow files now use the `.fabro` extension instead of `.dot`. This gives workflows a distinct identity and avoids conflicts with Graphviz `.dot` files. Existing `.dot` files still work as a fallback — the engine checks for `graph.fabro` first, then falls back to `graph.dot`.

```toml theme={"languages":{"custom":["/languages/dot.json","/languages/fabro.json"]}}
[workflow]
graph = "workflow.fabro"
```

<Warning>
  **Breaking change.** Workflow files have been renamed from `.dot` to `.fabro`. Existing `.dot` files continue to work as a fallback, but new projects should use `.fabro`.
</Warning>

## Smarter human gates

Human-in-the-loop gates now show the previous stage's output before prompting, so you can see what the agent produced before deciding what to do next. Gates with only a freeform edge also skip the multiple-choice menu and go straight to a text input, making conversational loops like REPL workflows feel more natural.

## User-level workflows

Personal workflows stored in `~/.fabro/workflows/` are now available across all your projects. Drop a workflow into your home directory once and run it from anywhere with `fabro run <name>` — no need to copy it into each repo.
