Your agent decides and writes; First100 holds the brand, the accounts and the data, and carries out what you approve.

Use your First100 account to manage connections, your key, and billing. Give instructions and review the work inside your agent.

Start with a specific outcome, such as finding communities for a launch or preparing next week’s posts. Your agent can gather context, show you proposed work, and carry out the actions you authorize.

Use First100 to check my connected accounts, then help me plan my next launch. Ask me for any missing context and show me the content before publishing.

For an agent reading these docs, start with the agent guide or the plain-text index.
