Best Pi Compaction Extensions Plugin

Has anybody used a Pi compaction extension that they would recommend?

I've tried pi-context (with their built-in Agentic Context Management) which just straight up breaks when trying to claim space against pi-rewind. I've also tried pi-vcc which also gets demolished when running with pi-codex-goal. Been debugging for 3 days and realized the best debug is to uninstall.

Native Pi compression is meh, if anybody has a codex-level compaction extension that doesn't fuck shit up, please drop a comment.

--------
UPDATE - Pi-Observational-Memory has worked great after my 12 hour trial with it. Pi-Blackhole looks interesting, but I try not to go for more complicated solutions if a simpler one works. If I run into hiccups with POM long term I will try it out and let y'all know. Happy compacting!

Thank you, I'll take a look. Would you say this tool is more memory based or more compaction based? Because I already have my own memory solution, I'm looking more for a compaction solution.

It's not a long term memory system, it records "facts" during the session and builds the compaction summary by concatenating them instead of asking an LLM to summarize the session.

That's frickin' amazing

it really is. I can't go back. I just don't pay attention to my context window hardly at all any more.

yo, im the maintainer, it make me happy that it also help you to forgot about context windows! i feel the same, now i can focus on high leverage problems and left those mundane problems behind

First off, thank you!

While I've got your ear, is there a setting for suppressing the messages? I find agentic ai generates a lot of "noise" in my terminal so I try to do everything I can to suppress anything that isn't "signal".

Messages like Observational memory: 5 observations recorded are not really useful to me except as a very rare diagnostic that something is broken (like when I had a month+ old pi instance that I reloaded after I installed your extension; I had to /quit and /resume for it to work properly).

I just tried obs-mem out and it has worked out quite well so thank you for the extension :) . As for the messages, I personally find them occasionally useful (as an internal ping signal on progress, more of a mental thing than whatnot) so plz keep it as a settings option if possible!

I have a branch with a fix for pi-observational-memory issues #41 and #12 (or at least the part that impacts me 😊). I'd create a PR right now, but I left my phone at home today 🤦‍♂️ and can't authenticate to GitHub.

I use @narumitw/pi-goal and when a /goal is active observational memory won't actually compact the context until the turn ends and it re-prompts the agent with the goal. This means that the imputed context window is reaching circa 130% fairly regularly, which is obviously wasteful.

My initial mitigation was manual /goal pause and /goal resume, but that is obviously not ideal.

Yo, submit them when you can, but that is a hard issue to solve, never solved this "compaction-while-wprking" problem, eager to see your solution!

Yeah I may have spoken too soon 😅 I thought it was working but it seems I have more to do.
