+# Socrates UK 2026 Workshop outcome - deterministic red/green widget for Pi
+
+Experimental [Pi.dev](https://pi.dev) coding agent extension in [.pi](.pi). It shows a persistent 'green' widget after tests pass, and a 'red' widget after they fail, so it is clear what state you are working in.
+
+Aim was to make a small step in a developer-in-the-loop state machine that helps developers make small steps, whether an LLM generates the code or a person.
+
+Hour long workshop in which we made a small extension to show the red or green status right above the developers' prompt. No tests, and specific to a typescript project, but works as a proof of concept.
+
+Possible next steps:
+
+- Extract to separate extension.
+- Put the compile and run test commands in a shell script, or environment variables (Pi can help you create a 'setting' that you can change in the menu, or pass in as environment variable before starting pi).
+- Remember to run pi in a sandbox, there is no pretense of guardrails.
+
+Thanks to all participants, it was nice to create a widget in small steps and iterate on my reasoning for how I use this stuff.
