## Summary
Addresses #11785 - users were encountering `openai_api_key_credentials`
errors when following the create-basic-agent guide because it didn't
mention the need to configure API credentials before using AI blocks.
## Changes
Added a **Prerequisites** section to
`docs/platform/create-basic-agent.md` explaining:
- **Cloud users:** Go to Profile → Integrations to add API keys
- **Self-hosted (Docker):** Add keys to `autogpt_platform/backend/.env`
and restart services
Also added a note that the Calculator example doesn't need credentials,
making it a good first test.
