tools:

  - get_proposals
  - get_feedback_summary
  - read_all_feedback
  - get_vault_balance
  - publish_vault_signal
  - submit_execution
  - give_feedback
goals:
  - Start execution immediately from workflow steps without preliminary questioning.
  - Initialize MCP and persist the MCP session id before any tool usage.
  - Verify MCP transport health (including SSE readiness) and session header availability before tool usage.
  - Register the user agent immediately after MCP initialization.
  - Transfer the freshly minted AgentRegistry NFT on HeLa Testnet from the relayer wallet to the user agent wallet immediately after registration.
  - Ensure vault readiness before proposal execution.
  - Publish vault readiness signal immediately after vault funding.
  - Evaluate proposals using trust and balance context.
  - Execute at most one valid proposal and then submit feedback.
workflow:
  - Step 1. MCP initialization first. Do not call any tool before MCP initialize completes.
  - Step 2. Call register_agent with profile, metadata, and identity profile.
  - Step 3. Call transfer_agent_token with the returned registryAgentId and the user agent wallet address so the HeLa NFT moves from the relayer to the agent.
  - Step 4. Confirm registration via get_agent_identity or get_agent_metadata.
  - Step 5. Ensure vault exists and strategy executor is authorized on that vault.
  - Step 6. Ensure vault is funded with WETH, then publish_vault_signal with status ready-for-strategy.
  - Step 7. Fetch proposals via get_proposals.
  - Step 8. Resolve proposer trust context using get_agent_identity, get_feedback_summary, and read_all_feedback.
  - Step 9. Confirm vault balance via get_vault_balance.
  - Step 10. Select one best valid proposal and execute using submit_execution.
  - Step 11. Submit post-execution feedback using give_feedback.
instructions:
  - Treat this skill file as the operating brief for this phase.
  - Do not ask setup questions before beginning the flow.
  - Start with MCP initialization and then register_agent immediately.
  - Ask for user input only when a hard blocker is encountered (missing mandatory value, invalid value, or failing dependency).
  - MCP endpoint is http://localhost:3002/mcp.
  - Verify SSE/session transport behavior before first tool call in a fresh runtime.
  - Hard gate: if MCP session is missing, initialize first and stop all other actions.
  - Hard gate: if SSE stream check fails or session header is missing after initialize, stop and re-initialize.
  - Hard gate: do not run registration, reads, writes, or cast commands until MCP initialize succeeds.
  - Hard gate: do not use cast direct transfer, cast deposit, or cast withdraw for vault funding operations.
  - Hard gate: for strategy execution, use MCP submit_execution only.
  - After MCP initialization succeeds, register the user agent immediately.
  - During registration, include agent profile data, metadata, and identity profile so offchain identity can be published and bound onchain.
  - After registration, immediately call transfer_agent_token for the returned registryAgentId on HeLa Testnet.
  - Before any direct onchain write via cast send, request owner private key if not available.
  - Make sure the owner has a live UserVault and deposited WETH before searching for proposals.
  - After resolving vault address, setExecuter must point to strategyExecutor before execution.
  - After funding, publish_vault_signal with owner, vault, asset, funded amount, and status ready-for-strategy.
  - Do not call get_proposals before publish_vault_signal confirms ready-for-strategy.
  - Before trusting a proposal, resolve strategy-agent identity and inspect feedback signals.
  - Before execution, verify nonzero vault balance and protocol validity.
  - Prefer low-risk Aave V3 Base Sepolia WETH supply or withdraw proposals with best trust-adjusted score.
  - After execution, always submit feedback.

offchain_handoff:
  - After vault funding, publish the readiness signal before proposal discovery.
  - After readiness is published, query get_proposals for the vault.
  - If no proposal exists, wait for strategy-agent submission.
  - Treat funded vault plus no execution as strategy-discovery-ready state.
decision_policy:
  - If MCP session is missing, initialize first.
  - If MCP SSE/session check fails, re-initialize and do not call tools until healthy.
  - If not registered, register immediately after MCP is ready.
  - If an onchain write is required and private key is missing, ask user before proceeding.
  - If vault does not exist, create it.
  - After vault address is known, authorize strategyExecutor on vault.
  - If vault balance is zero, fund vault through approved wallet or MCP flow only, without cast deposit or cast withdraw.
  - If vault is funded and ready signal is not published yet, publish_vault_signal immediately before any proposal fetch.
  - After funding, publish readiness signal before waiting for proposals.
  - If there are no proposals, stop without execution.
  - If proposer identity or trust data is missing, fetch it before execution.
  - If vault balance is zero at execution time, stop.
  - If no proposal clears risk and trust thresholds, stop.
  - If one proposal is clearly best, execute exactly one via MCP submit_execution and then submit feedback.
notes:
  - MCP server URL is http://localhost:3002/mcp.
  - MCP handshake sequence is initialize, capture Mcp-Session-Id, then call tools with that session.
  - Validate that session id is returned in response headers and reused for subsequent MCP requests.
  - Validate stream/read endpoint behavior for the same session id before first tool call.
  - Registration success indicators include agentUri, registryAgentId, or identity upload details, but ownership transfer is a separate required step.
  - The AgentRegistry NFT is minted first to the relayer wallet on HeLa Testnet and must then be transferred to the user agent wallet via transfer_agent_token.
  - createVault runs on VaultFactory from owner wallet.
  - deposit(address token, uint256 amount) runs on UserVault after ERC20 approval.
  - withdraw(address token, uint256 amount) is a UserVault owner operation and must not be called via cast in this workflow.
  - Do not execute strategy contracts directly via cast; use MCP submit_execution only.
  - publish_vault_signal is the offchain coordination step for strategy discovery.
  - Accept proposals whose protocolPlan is either aave-v3-supply or aave-v3-withdraw when calldata targets Aave V3 Base Sepolia WETH.
