Before and after prompts for Cursor Web Agent
Rough request on the left, the PromptDC rewrite on the right.
Before
Fix the Canadian tax mismatch between checkout preview and the final order.
After
Investigate why Canadian tax totals differ between checkout preview and completed orders. Scope the task to checkout calculation and order finalization code without changing tax rates. Cover Ontario and Quebec cases, rounding, discounts, and shipping tax treatment. Deliver a focused pull request with tests, root cause notes, and validation results.
Why this is better: The prompt adds regional cases and a pull request outcome so Cursor Web Agent can work independently.
Before
Upgrade the image worker to Node 22 and make sure its queues still work.
After
Upgrade the image worker from Node 20 to Node 22 without changing unrelated services. Update runtime declarations, container files, continuous integration, and the lockfile only as needed. Verify resize jobs, retries, Redis connectivity, and graceful shutdown in the new runtime. Open a focused pull request with commands run, results, risks, and any follow up work.
Why this is better: The prompt defines runtime surfaces and evidence so Cursor Web Agent can deliver a bounded upgrade.
Before
The settings tabs stopped responding to arrow keys after the redesign.
After
Find and fix the keyboard regression in the settings tab interface. Inspect recent relevant history and existing accessibility tests before editing the code. Restore arrow navigation, focus order, activation behavior, and narrow screen usability. Submit a focused pull request with browser test results and a concise root cause explanation.
Why this is better: The prompt adds history, accessibility checks, and delivery details for a focused web agent task.
