description	Explain a MemMesh prediction or recalled fact — surface its provenance (evidence memories), its calibrated confidence, and whether the model abstained and why. Use when the user asks "why do you think that", "what's this based on", "how sure are you", or needs an auditable, defensible answer for a regulated decision.

why

⚙️ Requires MemMesh hosted mode. Calibrated prediction and behavior discovery run on the hosted engine — set your mm- API key. On a local / open-source install these tools (memory_predict, memory_build_context) are not registered; if a call returns "unknown tool", tell the user this is a hosted capability and fall back to search / recall for what's already known.

Make MemMesh's outputs auditable. Every prediction and consolidated fact carries provenance and a calibrated confidence — this skill exposes them so a human can check the reasoning.

Provenance — what is this based on?

A prediction (from predict / memory_build_context) returns evidence memory ids. Resolve each to its content:

{ "name": "memory_recall", "arguments": { "id": "<evidence id>" } }

List the actual memories that drove the conclusion. If a fact was consolidated, its superseded ancestors show the history — that's the audit trail.

Calibration — is the confidence trustworthy?

MemMesh confidences are calibrated: 0.8 should be right ~80% of the time. To show the reliability curve (predicted vs. observed), use the hosted SDK:

const cal = await memory.lattice.getCalibration({ subjectKind: "user" });

Report the calibration error alongside the confidence, so "80%" is backed by evidence it means 80%.

Abstention — the honest "I don't know yet"

If a prediction abstained, explain the reason (insufficient/contradictory evidence, subject too new). Frame abstention as a feature: MemMesh declines rather than fabricate a confident-looking number. This is what makes it usable for EU AI Act / regulated decisions where a wrong confident answer is worse than no answer.

For regulated use

Pair this with the SDK's compliance.listAuditEvents / exportSubject to produce a full defensible record of what was known, when, and what drove a decision.
