WISHLIST: pre-execution governance gate action (advisory verdict before order placement)

The WISHLIST covers DeFi actions, NFT, cross-chain, social — but nothing in the governance / pre-execution verification lane. Suggesting it here since it's a natural complement to the trading and DeFi actions already listed.

## The gap

An agent executing a Uniswap swap or DeFi action via AgentKit has no standard way to get an independent, account-aware verdict on whether that specific action is sound *before* it fires. Each action currently self-validates (parameter bounds, wallet balance) but has no cross-action capital-scale awareness.

## What the action would look like

```python
# pseudocode — advisory, never blocks
verdict = agentkit.review(
artifact_type="onchain_action", # or "trade", "transfer", etc.
artifact={"action": "uniswap_swap", "amount_usd": 5000, "token_in": "ETH", "token_out": "USDC"},
account_context={"equity_usd": wallet.balance_usd, "open_positions": ...}
)
# verdict.verdict in {"approve", "approve_with_concerns", "reject"}
# verdict.proof — signed, recomputable, attached to the action's audit trail
if verdict.verdict == "reject":
log_and_hold() # advisory — agent decides whether to proceed
```

## Reference implementation

`invinoveritas /review` does this today — MCP-native, x402/USDC on Base (same rail as AgentKit), advisory+fail-open. Live dogfood: a Hyperliquid trading bot passes every entry through `/review` before placement. Community example with AlgoVaultLabs (ERC-8004 verified): https://github.com/AlgoVaultLabs/crypto-quant-signal-mcp/pull/28

Happy to contribute this as an actual AgentKit action if it fits the roadmap.
