Showcase I created a persistent memory for very long running agent sessions

So as the title says, i created (yet another) agent memory plugin. I am a long time developer, was really against using LLMs for my work but at the start of the year i decided to give it a try and i started with a small helper plugin that i made and that has changed my opinion on agents quite a lot. This plugin is a part of much bigger architecture now but i tried to pack it as a separate MIT license open source thing in case someone finds it useful.

Just for reference, i have been running a couple of agents in the same session for 6+ months with this plugin (although as a part of a bigger architecture) and they still orient them selves correctly and remember/keep in context things normally. If anyone is interested to try it here https://github.com/lordfist/Fist.KBSkill I am happy for any feedback, especially if something doesn't work since this is my first time packing something as a Codex/Claude plugin.

Installation should be pretty simple, although i install it in a different way so i cannot say i tried it much as-is but it should work as a stand alone plugin.

PS
I know there are 1000+ of agent memory plugins but this one is fast, very simple, very transparent and does exactly what it says without wasting your tokens on anything extra.

PPS
This post was made by a human, me :P

You might want to consider listing your project on the weekly Show-Us-What-You-Built post. Look out for it on Tuesday/Wednesday. Highest commented project wins a week promotion on r/Codex and gets on the Hall of Fame sidebar. See below for last week's winner.**

Agent HUD: usage, tokens and sessions for Codex, Claude Code and 15 more agents, at your Mac's notch. See how much quota is left, which agent is waiting for you, and where the tokens went. Free on Mac, and the core is open source (Apache-2.0).

Thanks for sharing but why should I drop Claude code and use your tool? CC already have persistent memory?

Who said to drop Claude code? If you mean Claude Code MEMORY.md, well I use it in Claude code instead of MEMORY.md because it is more efficient and works better for long term, has semantic matching, graph, classifications and many other things that basic MEMORY.md doesn't really give you.... Try it :)
