System Prompt Workspace

Route: /#/basic/system

Use this workspace for long-lived constraints such as role design, behavior boundaries, and output policy.

If your main problem is how to phrase one concrete task, User Prompt Workspace is usually a better fit.

First-time rule of thumb

If both are true, this is usually the right page:

  1. you are editing long-lived role / rule / boundary content
  2. the right side needs one test message before it can run

Typical use cases

  • define a stable model role
  • enforce a reusable output structure
  • define what the assistant must not do
  • test whether the model keeps rules across different questions

If you only want the fastest start

  1. enter one system prompt on the left
  2. run one left-side optimization
  3. enter one test message on the right
  4. run testing, then Result Evaluation

What the left side edits

The left side edits the system prompt itself.

You can think of the page like this:

  • upper-left: original system prompt
  • lower-left: current workspace draft and saved versions

What the right side tests

The right side tests:

  • one system prompt version
  • one fixed test message
  • the real output

That is why the right-side test message is required in this workspace.

Analysis vs evaluation in this page

  • left-side Analysis: inspects the system prompt itself, not the test message
  • right-side Result Evaluation: judges whether one real output reached the goal
  • right-side Compare Evaluation: compares multiple real outputs
  1. enter the original system prompt
  2. optimize it once on the left
  3. use left-side analysis if you want prompt-only feedback first
  4. enter one fixed test message on the right
  5. compare original / workspace / vN
  6. start with Result Evaluation
  7. then run Compare Evaluation if you have multiple columns
  8. apply valuable suggestions back to the left workspace

Common confusions

  • Left-side analysis does not read the test message. It analyzes the system prompt itself.
  • The right-side test message is required because a system prompt usually cannot reveal its behavior on its own.

A minimal example

System prompt:

You are a customer support assistant.

Right-side test message:

My order has not shipped for three days. Can I request a refund now?

With that setup, you can compare:

  • whether the original version is too vague
  • whether the workspace version follows boundaries more reliably
  • whether different models misunderstand the same system prompt in different ways
