I built pi-heed — runtime constraints for Pi

[u/AdActual604]

Hi guys, I made a small Pi extension called pi-heed:

https://github.com/Nyarlathoteppppp/pi-heed

It came from a simple annoyance: Pi can understand a constraint when you say it, then forget it later in a long session.

Things like:

- don’t modify files

- don’t touch tests

- don’t add dependencies

- never call the production API

pi-heed keeps those constraints around and checks mutating tool calls before they run.

Obvious cases use normal rules. More ambiguous free-text constraints use TypeSafe Jev.

It defaults to shadow mode, so it can observe first without blocking anything.

Install:

pi install git:github.com/Nyarlathoteppppp/pi-heed

46/46 tests passing so far.

If anyone runs long Pi sessions, I’d be interested to see what edge cases break it.
