⭐ Our specialty — the coupling no one else shipsAgent teams

Your agents finally share a brain.

When an orchestrator hands work to subagents and tools, they all read and write the same memory — so nobody re-explains context, and nothing leaks where it shouldn't.

The problem[1 / 7]

Run more than one agent and they each start from zero.

You bloat every prompt with context just to keep them in sync — and it still drifts.

Before · 01

Re-explaining context

Every handoff means pasting the whole story into the next agent's prompt. It is slow, expensive, and easy to get wrong.

Before · 02

No idea who learned what

One agent discovers something useful and the rest never find out — or worse, two of them act on opposite versions of the truth.

One shared memory[2 / 7]

Each agent keeps its own scratch space — until it's worth sharing.

The moment something's worth sharing, it's promoted to the team memory — and only then can other agents see it.

DENIED · IDENTITY

Untrusted instruction from a fetched page — held back.

The shared region fact superseded an older one — the team now reads the current truth, with the change attributed.

Provenance[3 / 7]

Who learned what, and from where.

Every memory knows which agent wrote it and which parent authorized that agent. Subagents inherit access automatically — and only the slice they're allowed.

Stays right[4 / 7]

It stays right when agents disagree.

When two agents write contradicting facts, the team memory keeps the current one and fades the superseded one. No more two agents acting on opposite 'truths'.

Safe by default[5 / 7]

Private stays private, suspect content stays quarantined.

Three promises that answer the question every team asks first.

PRIVATE BY DEFAULT

Private stays private

Each agent's scratch space is its own. Nothing crosses into the team memory until it's promoted.

POISON-RESISTANT

Suspect content is quarantined

Injected or untrusted writes are held back and flagged — never silently trusted by the rest of the team.

FULLY AUDITED

Every write is attributed

Who wrote it, which parent authorized them, and when — every memory carries its provenance.

Developer proof[6 / 7]

Drop it into your team.

The orchestrator calls recall; a subagent inherits a scoped token and calls remember — and the same memory id surfaces in both.

from ultramemory import Memory

# Orchestrator reads the shared team memory
mem = Memory(agent="orchestrator")
facts = mem.recall("deploy region", scope="shared")

# A subagent inherits a scoped token and writes back
sub = mem.delegate(agent="researcher")
saved = sub.remember(
    "Production region is eu-central-1",
    scope="shared",
)
print(saved.id)  # mem_7Qk… — same id the orchestrator now recalls

Watch one shared fact move between agents.

Raw → extraction → fact → retrieval — one fact's journey from the Researcher's note to the Coder's recall, with the misses observable, not silent.
