Adding an Agentic Action to the Langchain Toolkit

1. Ensure the action is implemented in cdp-agentkit-core.
2. Add a wrapper method to CdpAgentkitWrapper in ./cdp_langchain/utils/cdp_agentkit_wrapper.py
   • E.g.

    def mint_nft_wrapper(self, contract_address: str, destination: str) -> str:
        """Mint an NFT (ERC-721) to a specified destination address onchain via a contract invocation.

        Args:
            contract_address (str): "The contract address of the NFT (ERC-721) to mint, e.g. `0x036CbD53842c5426634e7929541eC2318f3dCF7e`".
            destination (str): "The destination address that will receieve the NFT onchain, e.g. `0x036CbD53842c5426634e7929541eC2318f3dCF7e`".

        Returns:
            str: A message containing the NFT mint details.

        """
        return mint_nft(
            wallet=self.wallet,
            contract_address=contract_address,
            destination=destination,
        )

3. Add call to the wrapper in CdpAgentkitWrapper.run in ./cdp_langchain/utils/cdp_agentkit_wrapper.py
   • E.g.

        if mode == "mint_nft":
            return self.mint_nft_wrapper(**kwargs)

4. Add the action to the list of available tools in the CdpToolkit in ./cdp_langchain/agent_toolkits/cdp_toolkit.py
   • E.g.

        actions: List[Dict] = [
            {
                "mode": "mint_nft",
                "name": "mint_nft",
                "description": MINT_NFT_PROMPT,
                "args_schema": MintNftInput,
            },
        ]

5. Add the action to the list of tools in the CdpToolkit class documentation.
