Solve custom logic puzzles in Cursor
When you change the rules of a classic puzzle, agents usually fail by reciting the old answer. The `validate_counterfactual` tool forces the agent to break down your specific variables before it writes a single line of code or text. This tool maps the discrepancies between your new rules and the original puzzle. It keeps the agent honest by preventing it from relying on its training data.
Decontaminate reasoning in Cursor
You need the agent to perform calculations from first principles. By calling this tool, you ensure the logic is built from your provided parameters, not from cached patterns. This makes Cursor much more reliable for tasks involving modified constraints. The agent must prove its work step-by-step before finalizing the output.
Audit agent output inside Cursor
Use the tool to verify that the final result is clean. If the server flags the response, the agent has fallen back on a template and needs to be re-prompted. This keeps your technical documentation and logic sets accurate. You stop the agent from giving you the wrong answer to a modified problem.
