Memory Tools
May 9, 2026 ยท View on GitHub
The Memory Tree is OpenHuman's knowledge base. The memory tools are how the agent talks to it during a conversation.
Tools in the family
| Tool | What it does |
|---|---|
recall | Search the Memory Tree by query - source-scoped, topic-scoped, or global. Returns chunks with provenance. |
store | Write a new memory the agent decided is worth keeping (a fact, a preference, a piece of context). |
forget | Remove a memory by ID - used when something is wrong, stale, or the user explicitly asks to forget it. |
There is also a tree-aware retrieval surface (drill down a topic, fetch the global digest for a day) - the agent picks the right one based on the question.
Why these are tools, not implicit context
The Memory Tree is too big to dump into every conversation. The tools let the model ask - "what do I know about Alice?", "what happened yesterday?", "remind me of last week's Stripe webhook" - and the retrieval layer returns just the relevant chunks, with provenance back to the source file in your Obsidian vault.
