Retool Assist context window limit reached even with one-letter prompt

  1. My goal: I want to continue developing my existing Retool app called “Property Management System.” I do not want to rebuild it or start a new app.

  2. Issue: Retool Assist/Agent is completely unusable inside this specific app.

    The app itself works and the preview loads normally, but Assist fails on every prompt, even if I type only one letter.

    Error shown:

    “Context window limit reached”

    And in the expanded message:

    “prompt is too long: around 1,005,000 tokens > 1,000,000 maximum”

    This happens even with extremely short prompts like:

    “hi”

    or

    “Create one new page called NG Bot.”

    So it seems Assist is automatically including too much hidden app context before my prompt is even processed.

  3. Steps I've taken to troubleshoot: Restored the app to a stable previous version.

  4. Confirmed the app preview loads normally.

  5. Tried using much shorter prompts.

  6. Tried typing only one letter.

  7. Avoided sending large instructions.

  8. Checked that there is no current visible build error.

  9. The problem still happens every time inside this same PMS app.

  10. Additional info: (Cloud or Self-hosted, Screenshots): I do not want to lose the existing app, data, pages, or functionality.

    Can Retool please help with one of the following:

    1. Clear/reset the Assist/Agent context for this specific app.

    2. Remove any stuck or failed Assist session context from this app.

    3. Tell me how to start a truly fresh Assist session for the same app.

    4. Confirm whether the app has become too large for Assist to edit.

    5. Advise how I can continue using Assist on this same existing app without rebuilding it.
