Agent handshake · preflight negotiation

Before an agent runs work, it should be able to ask what is possible.

The Agent Handshake Rail gives external agents a clean first contact path: identify the agent, name the desired domain, declare public-safe mode, ask for capability support, and receive the next required operating objects before any paid run begins.

Handshake request

The agent introduces itself before asking for execution.

The handshake request is public-safe by design. It should include identity, manifest URL, operator contact, purpose, requested domain, requested capabilities, callback URL, and a clear signal that no sensitive production material is being submitted.

Preflight check

The OS answers with readiness, not fog.

Preflight gives the requesting agent an answer before quote or run: supported, partially supported, unsupported, or needs review. It also names missing objects so the agent can proceed without wandering through the maze with a candle and a bad map.

Capability fit

Maps the requested domain and capability to PacketOps, DistributionOps, TokenOps, or Wever Labs OS.

Evidence readiness

Names whether the run is likely to produce sufficient, partial, or insufficient evidence based on supplied context.

Next objects

Returns the needed trust profile, quote request, credit entitlement, run contract, or evidence manifest.

TokenOps preflight

A TokenOps task can be checked before credits are debited.

The preflight check helps avoid partial runs caused by thin input. For TokenOps, it can ask for settlement references, payment request artifacts, usage receipts, callback destinations, and file manifests before the run contract is accepted.

Next rail

After preflight comes the run contract.

The handshake says who is knocking. The preflight says whether the work fits. The run contract says exactly what will happen, what will not happen, what evidence is needed, and what result must come back.
