Keeping an agent conversation in memory

Claude Code and Antigravity write every conversation to your disk. Claude Code deletes its own after 30 days. Ariadne, the Hub app that reads these conversations, can keep them in a Mnemosyne OS vault. You then find them by asking the chat, or through an agent that queries your memory.

What you need first​

The vault you pick must watch a folder that takes Markdown. Add a watched folder in the vault settings if it has none. Keep the folder depth at 1 or more: Ariadne writes into an agent-sessions subfolder.

Keep a conversation​

In Ariadne, open a session. In the "Keep the conversation in memory" block, pick the vault and press "Keep this conversation".

To keep several, tick them in the session list, then press "Keep N conversations". A conversation kept before is replaced by its new version. If it has not changed, nothing is written again.

What is kept​

Ariadne writes one Markdown file per session. Your messages and the agent's are in it, each under a heading with the date. The tools it ran fit on one line per exchange. Tool results and the agent's thinking are left out.

A section that holds a key, a token or a blocked word is left out. The screen says how many sections were left out and why. A password typed in plain text has no recognisable shape: it stays in the file.

In the chat, Mnemosyne OS serves your messages in full and one line for each of the agent's answers. An agent that queries your memory gets both.

Keep a project automatically​

In the "Keep this project automatically" block, press "Keep its finished sessions". Mnemosyne OS asks for your agreement first, in its own window.

From then on, each session of this project is kept once it has not moved for 24 hours. A pass runs 2 minutes after the app starts, then every 3 hours, 25 sessions at most each time. "Run now" runs a pass right away. "Revoke the rule" stops it, and the sessions already kept stay in the vault.

What stays on your machine​

A kept conversation never leaves through P2P, even when its vault is shared with someone. A coding agent's conversations hold your code, and the secret check does not recognise code as a secret.
