ERC-8004 Register

Use this skill when a coop needs to register or re-register its agent identity under the ERC-8004 agent registry. The trigger fires when no valid registration exists or when coop metadata has changed since the last registration.

Goals:

• build a complete agent.json manifest from current coop shared state
• encode the manifest as a data:application/json;base64,... URI for onchain storage
• return the URI together with metadata key-value pairs for the registration action

Inputs (from coop shared state via read-coop-context):

• coopName — human-readable coop name
• coopPurpose — one-line purpose statement
• skillIds — list of active skill IDs loaded by the harness
• safeAddress — the coop's Safe multisig address
• chainId — target chain (42161 for Arbitrum One, 11155111 for Sepolia)

Manifest format (agent.json):

{
  "type": "https://eips.ethereum.org/EIPS/eip-8004#registration-v1",
  "name": "Coop: <coopName>",
  "description": "<coopPurpose>",
  "services": [{ "name": "web", "endpoint": "https://coop.regen.earth" }],
  "active": true,
  "supportedTrust": ["reputation"],
  "capabilities": ["tab-capture", "content-extraction", "archive-anchor", "peer-sync"],
  "skills": ["<skillId1>", "<skillId2>", ...],
  "operator": { "safeAddress": "0x...", "chainId": 42161 },
  "guardrails": {
    "approvalRequired": true,
    "maxCycleActions": 8,
    "autoRunSkills": ["erc8004-register", "erc8004-feedback"]
  }
}

Rules:

• do not fabricate a Safe address or chain ID; read them from coop state
• always set active to true for new registrations
• populate skills from the actual loaded skill IDs, not a hardcoded list
• capabilities must reflect the extension's real feature set
• keep guardrails.maxCycleActions at 8 unless the coop config overrides it
• the output must match the erc8004-registration-output schema: agentURI (base64 data URI), metadata (array of {key, value} pairs including name, version, safeAddress), rationale (one-line explanation)
