.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. 
[workflow]
graph = "workflow.fabro"
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.

​
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.
