Knowledge: how to make it works?

after one month using AG, 3 proyects, one started from scratch… knowledge is empty

the videos in youtube are good… but they look fake promise, and this is a common issue posted in reddit.

so, I post here if someone can tell me how make it works,

Without codebase indexing(cursor feat), context engineering (augmentcode), needing retry each 3 messages, and lowering opus limits (yes, Gemini 3 pro isn’t usable to touch code), MY only reason with AG is the compound knowledge…

  • Same experience.
  • If explicitly asked, agents know nothing about “knowledge items”, so it’s not even on the system prompt.
  • The placeholder in Agent Manage knowledge section is not clear – “The agent has not generated any knowledge items yet” - is this a global section? Which agent?

Same. I was reading Google Antigravity, and it sounds like a fantastic feature. I’ve been using Antigravity for over a month now, but when I click the Knowledge tab, its empty: “The agent has not generated any knowledge items yet.”

I read from a redditor that adding

 "codeiumDev.useDevUnleash": true,

to settings.json enabled Knowledge for them, but it didn’t work for me :confused: .

Has anyone figured out a way to make it work?

This feature doesnt work from day one. I couldnt find any trick to make it work. Its very sad.

Thank you for reaching out. To assist you effectively with the ‘Knowledge’ feature, could you please provide additional context? Sharing screenshots, specific error messages, or the steps taken to reproduce the issue would be invaluable to our investigation.

Im using Google Pro subscription. I have “knowlage” enabled in the “settings - agent” window.

I mostly use agent manager with multiple workspaces.

From what I understand, knowlage should be generated automaticaly (similary like in Google Jules). Yet, there is no knowlage artifact generated, ever.

Im using latest version of Antigravity.

Reinstalled multiple times. Cleaned %appdata% folder, and “.gemini” folder. Tried multiple PC’s and 2 accounts - it doesnt work.

Sorry, i cant share media, because it tells me that new accounts cant emmbed media.

It’s also not working for me. What I tried:

  • Wait for updates to fix it
  • Restart multiple times
  • Use another repo
  • Install Antigravity on another machine
  • Switch the feature off and on again
  • Let Gemini investigate what could be wrong

All I get is a knowledge.lockfile in the knowledge folder, which will be re-created when I delete it.
