Fact Extraction & Tools

See Reflections & Knowledge for the full picture: reflecting on past work, and promoting the answers into FACTS.md / AGENTS.md / ADRs / skills.

Umwelten no longer exposes automatic chat memory as a public chat mode. Interaction always uses the base runner.

For knowledge workflows, use the explicit memory helper APIs from packages/core/src/memory/:

• extractFacts(interaction, modelDetails) extracts structured facts from an Interaction.
• determineOperations(modelDetails, facts, existingMemories) proposes ADD/UPDATE/NONE operations for a caller-managed store.

Tool usage remains configured through Stimulus.tools and CLI --tools options where available.
