Assistance Needed for Configuring Lead Gen Agent Workflow Skills

Hi Marvin A. Ethan K. Rex H. I need one question I was trying to create lead gen agent workflow for specific niche and ICP. I have tried multiple iteration in order to find which one work... but honestly in order to fine-tune this agent ... make sure it delivers the best output, I asked the agent builder to create one... I have lost 3K credits already🫠😬.. after seeing the credits left i thought try it manually now. But now I am stuck in the agent step... once you add skills to the agent step how can we configure or edit the instructions of those skills. I can't find anyway to edit it. can you pls help.
