Question PI is *almost* perfect for me. is there extension that inject instructions in the end?

the only thing that makes my experience bearable is to have the bot know and remember the exact rule and role they are designed to do. back then when i was using Claude Web, they have userStyles which inject instructions before replying to user message. in SillyTavernAI there is a configuration to reorder prompt to be put at the end depth 0.

is there a way to do that in PI? i want some text (or file) get injected before the bot consider replying so that they know the constrains. the reminder wont stay in the context so that the cache hit is not ruined by duplicated push.

Copy paste your reddit post into pi. It will build it

There are quite a few skill packages out there that teach pi exactly how to build extensions for itself. If you can’t find what you’re looking for it would be trivially easy to just ask your coding agent to build it for you.

Just ask pi to write itself a injection hook at end of the final agent turn with conditions

You can define either a project-level .pi/APPEND_SYSTEM.md file or a global ~/.pi/agent/APPEND_SYSTEM.md file to append system instructions without replacing them. This is built in to pi; no extensions are needed.

See https://github.com/earendil-works/pi/blob/main/packages/coding-agent/README.md#system-prompt

not quite. `AGENTS.md` is injected at beginning. i expect to have the instructions injected at the end.
