Step by step

  1. Pick one goal

    For example: find five papers on a topic and summarise them.

  2. Give it tools

    Web search to find pages, and a reader to open each one.

  3. Choose a model

    Claude, GPT or Gemini does the thinking.

  4. Wire it and run

    Use Cursor, LangChain or Claude to connect the parts and start it.

  5. Check the output

    Read the summary, improve the instructions, run it again.

Small goal first. Add tools only when the agent needs them.
