Cognition
Cognition session-end memory — facts regex-extracted from your messages at session end, stored in a local SQLite queue and JSON log under one repo label, with fetch-first merge, per-entry provenance, and budgeted prefetch (tools: cognition_search, cognition_status, read-only cognition_dream).
Good to know before installing
Saves verbatim excerpts (up to 400 chars) of your own messages that match preference/decision phrases in plain local files under HERMES_HOME/cognition/ (SQLite queue, JSON commit log) and re-injects them into later prompts sent to your model provider; the author name is read from ~/.gitconfig; the plugin makes no network calls of its own.
From the plugin's catalog listing.
How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install cognition - Said no? Turn it on later:
hermes plugins enable cognition - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
