## Tools (as reported by the server, not verified)

- `graph\_upsert`: Fold new facts into a memory graph and get the whole graph back. FREE. Idempotent by construction: re-adding the same entity, observation or relation changes nothing, so an agent that replays its own history does not end up with a graph full of duplicates. Typical input \{"graph": \{"entities": \[\], "r
- `graph\_search`: Find what the graph knows about something, plus its neighbourhood. FREE. Scores entities by how many query words appear in the name, type and observations, then pulls in whatever is within the requested number of hops - because the useful answer to "what do we know about Acme" is usually Acme plus w
- `graph\_diff`: Say exactly what changed between two versions of a memory. FREE. The audit trail a database gives you for free, without the database. Typical input \{"before": \{...\}, "after": \{...\}\} returns \{"entities\_added": \["Beta Ltd"\], "entities\_removed": \[\], "observations\_added": \{"Acme Corp": \["renewed in Marc
- `graph\_lint`: Find the breaks a memory graph accumulates as it grows. FREE. Relations pointing at entities that do not exist, entities nothing points at, near-duplicate names, and observations that contradict each other on the same entity. Typical input \{"graph": \{...\}\} returns \{"ok": false, "dangling\_relations":
- `graph\_at\_time`: See the memory as it stood on a given day, optionally faded by age. PREMIUM \(license\). Relations carrying since and until are filtered to those in force on the date; with a half-life, confidence decays exponentially with age so a two-year-old belief does not weigh the same as last week's. Typical in
- `graph\_compact`: Shrink a memory to the part that still earns its place. PREMIUM \(license\). Ranks entities by how connected they are and how much is recorded about them, keeps anything you name outright, and drops the rest along with the relations that pointed at them. Typical input \{"graph": \{...\}, "max\_entities":
