What PromptDC for Desktop does inside Copilot.
Review before Replace
Select your prompt, use the desktop shortcut, and review the rewrite before Replace or Copy.
Clearer prompts
Turn a rough request into a complete prompt with the details Copilot needs before you send it.
Supported app coverage
PromptDC for Desktop works in supported coding apps and their integrated terminals.
Set coding defaults
Choose any profile that fits, or add your own profiles and Custom Actions.
Reuse saved context
On the Code profile, use Always Include for project rules. Custom Action works with any profile for one-off guidance.
Choose output formats
On the Code profile, choose Regular, JSON, XML, or YAML output. Auto keeps your prompt's original language on every profile.
Before and after prompts for Copilot
Rough request on the left, the PromptDC rewrite on the right.
Before
Fix our VS Code debug task dropping test env vars when the path has spaces.
After
Fix the debug setup so test environment variables load from workspace paths containing spaces. Inspect the current launch configuration and helper scripts before changing them. Preserve user supplied launch values and support both Windows and macOS path formats. Add a focused test or reproducible check for spaces, quoting, and precedence.
Why this is better: The prompt adds platform and precedence checks so Copilot can fix debug environment loading portably.
Before
Add an endpoint to archive projects with no active deployments.
After
Add an authenticated endpoint that archives a project only when it has no active deployments. Follow the existing Spring Boot controller, service, authorization, and error response patterns. Return a conflict response when an active deployment exists and leave the project unchanged. Add service and endpoint tests for allowed, forbidden, missing, and conflicting requests.
Why this is better: The prompt supplies authorization and conflict behavior so Copilot can implement the endpoint safely.
Before
Why is ProductRow still rerendering after I wrapped it in React.memo?
After
Explain why ProductRow still renders when the parent search text changes. Inspect the current props, inline callbacks, filtered objects, and memo comparison in the open project. Distinguish a component render from an actual browser document update. Identify each unstable prop and recommend the smallest change with measurable benefit.
Why this is better: The prompt focuses Copilot on prop identity so its VS Code analysis can pinpoint unnecessary renders.
