4 use cases

  • Get a daily priorities summary on a schedule

    Have Endo run a standing prompt every weekday morning and read the result in chat.

    View prompt
    In the Endo repo at longsurf-ai/endo, help me set up a weekday 9 AM schedule that summarizes <my priorities source>. Expected output: a schedule entry on the Schedule page with the prompt and cron timing. Verify the next run time shown matches 9 AM on a weekday.
  • Compare answers from Codex and Claude Code in one thread

    Ask one question, switch agents mid-thread, and dig into the answer that fits best.

    View prompt
    Using the longsurf-ai/endo repo, set up a chat where <my question> is answered first by Codex, then by Claude Code in the same thread. Expected output: two answers in one thread, with the second agent referring to the first. Verify that the Claude Code answer reflects the earlier history.
  • Fan a question out to several agents with best-of-n

    Run the shipped best-of-n workflow to collect and compare multiple agent answers.

    View prompt
    In the longsurf-ai/endo repo, run the /best-of-n workflow on <my question> from the Endo chat. Expected output: a Workflow card listing each agent call and the candidate answers. Verify that calls from more than one provider appear before you accept a result.
  • Add a typed Resource to the Endo app for your own data

    Define one table and schema, then get an API, agent tools and live updates from it.

    View prompt
    In the longsurf-ai/endo repo, follow docs/architecture/resource.md to add a Resource for <my data type>, defined once as a Drizzle table and an Effect Schema. Expected output: the new resource exposed through the typed API and agent tools. Verify that an agent tool can read and write a record and that the change shows in the app.
