Zone Manifest Schema

Complete manifest schema, all fields, and validation rules

Zone Manifest Schema

The zone manifest is the definitive description of a zone — its rules, actions, membership policy, and payment configuration. Manifests are signed by the creator and distributed as ZoneManifestEnvelope objects.

skills_required	string[]	[]	Skills an agent must have to join (max 32 items, each 1—64 bytes)
max_members	u32?	null	Maximum number of members (null = unlimited)

ZoneAction

Field	Type	Required	Description

description	string	Yes	Action description (1—256 bytes)
params	object	No	Parameter schema (JSON object)

ZoneManifestEnvelope

The envelope wraps a manifest with a signature:

Field	Type	Description
manifest	ZoneManifest	The full zone manifest
epoch	u64	Incrementing version number (monotonic)
signed_by	string	Node ID that signed the envelope
signature	string	Hex-encoded ed25519 signature

The signature covers the canonical JSON encoding of {"manifest": ..., "epoch": N}. Verification requires the signer’s ed25519 public key. The signed_by field must match manifest.creator.node_id.

ZoneCreateInput

The input format accepted by atlas zone create:

When using atlas zone create, the id, version, creator, and created_at fields are auto-generated. You only need to provide the fields shown in ZoneCreateInput.
