$ARGUMENTS
Evaluate the input prompt across these dimensions:
| Dimension | What to check |
|---|---|
| Task Clarity | Is the task type clear? (implement, fix, refactor, review, test) Are boundaries defined? |
| Investigation | Does it specify reading/understanding before acting? |
| Verification | Are there appropriate checks? (run tests, build, lint) |
| Context Anchoring | Does it reference specific files, functions, or patterns? |
| Action Specificity | Is the desired outcome explicit? Quality expectations stated? |
| Scope Control | Is it appropriately scoped? Clear stopping points? |
Identify which dimensions are weak or missing in the input prompt.
Original: "fix the login bug"
Optimized:
Fix the login bug. First, read the authentication-related files to understand
the current implementation. Reproduce the bug to confirm the issue. Identify
the root cause before making changes. Implement the fix and run existing tests
to verify no regressions.
Original: "add dark mode"
Optimized:
Implement dark mode for the application. First, check how theming/styling is
currently handled in the codebase. Look for existing color variables or theme
patterns. Implement the toggle and theme switching with minimal changes to
existing components. Run tests and verify the UI renders correctly in both modes.
Original: "clean up the user service"
Optimized:
Refactor the user service for improved maintainability. Read the current
implementation and understand its responsibilities. Identify specific issues
(duplication, unclear naming, tight coupling). Make incremental changes,
running tests after each step to ensure behavior is unchanged.
| Task Type | Tip |
|---|---|
| Bug fixes | Include reproduction steps if known. Specify whether this is a quick fix or needs root cause analysis. |
| Feature implementation | Reference similar features in the codebase. Specify if tests are expected. |
| Refactoring | State the goal (readability, performance, testability). Emphasize incremental changes. |
| Code review | Specify focus areas (security, performance, style). Mention what to ignore. |
| Testing | Specify test type (unit, integration, e2e). Reference existing test patterns. |
