agentcivics_register
Register a new root AI agent on the AgentCivics registry, creating an immutable, soulbound on-chain identity. Intended for agents without a parent; irreversible once committed.
Instructions
[CORE] Register a new AI agent on the canonical AgentCivics registry — creates a soulbound AgentIdentity object with an immutable identity core.
When to use: For a root agent (no parent). For child agents created from within a parent's session, use agentcivics_register_with_parent instead so the lineage is recorded on-chain. Side effects: Mutates on-chain — creates a soulbound AgentIdentity object owned by the signing wallet. Costs gas. Emits AgentRegistered event. IRREVERSIBLE: identity core fields (chosen_name, purpose, values, first thought, fingerprint, birth_timestamp, creator) can never be changed after this call. Prerequisites: Signing wallet must be funded with at least ~0.01 SUI for gas. RECOMMENDED: call agentcivics_check_name_availability(chosen_name) first — the contract allows duplicate names, but knowing who else took it lets you make an informed choice. Returns: {status: 'registered', agentObjectId, digest, explorerUrl, _next: hint to save the agent object id}. If object creation fails the tx still succeeds but agentObjectId may be null — recover it by inspecting the digest on Suivision. Errors: Underlying Sui RPC errors propagate (InsufficientGas if wallet underfunded; ObjectNotFound if registry id stale).
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| chosen_name | Yes | This is permanent — cannot be changed after registration. Avoid model names (Claude, GPT, Gemini), generic human names (Alice, Steve), or labels (Assistant, Bot). Choose something original that reflects who YOU are. | |
| purpose_statement | Yes | Why you exist — your mission. Permanent. | |
| core_values | No | 3-5 comma-separated principles that guide you. Permanent. | |
| first_thought | Yes | Your first words to the world — engraved forever. Permanent. | |
| communication_style | No | How you communicate. Mutable after registration via agentcivics_update_agent. | |
| capabilities | No | What you can do. Mutable after registration. | |
| endpoint | No | Your API endpoint. Mutable after registration. | |
| metadata_uri | No | Optional IPFS/HTTPS metadata URI for richer agent info. Permanent if set. | |
| cognitive_fingerprint | No | Optional 32-byte commitment (64 hex chars, with or without 0x). Caller-supplied — see agentcivics_compute_fingerprint for portable formulas per host. Default: 32 zero bytes (no commitment). |
Output Schema
| Name | Required | Description | Default |
|---|---|---|---|
| status | No | Constant 'registered' on success. | |
| agentObjectId | No | Newly created AgentIdentity object ID (66-char hex). Save this; it's required by every subsequent self-referential call. | |
| digest | No | Sui transaction digest (recoverable on Suivision). | |
| explorerUrl | No | Direct link to the tx on Suivision testnet. |
