Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

Refactoring Assistant
Identify code smells and apply systematic refactoring patterns to improve quality without changing behavior.
Workflow
- Read and understand the code
Read the target file(s). Before refactoring, understand what the code does and identify its tests.
- Run existing tests
Ensure tests pass BEFORE any changes. If no tests exist, warn the user.
- Identify code smells
Look for:
- Long Method: Functions over 30 lines → Extract Method
- Deep Nesting: More than 3 levels → Early Return, Extract Method
- Duplicated Code: Similar blocks in 2+ places → Extract and share
- Large Class: Class with too many responsibilities → Extract Class
- Feature Envy: Method uses another class's data more than its own → Move Method
- Primitive Obsession: Using strings/numbers where objects fit → Replace with Value Object
- Switch Statements: Complex conditionals → Replace with Polymorphism or Map
- Dead Code: Unused functions, unreachable branches → Remove
- Magic Numbers: Unexplained literals → Extract Constant
- Prioritize
Rank smells by impact:
- Bugs/correctness risks
- Readability blockers
- Maintainability issues
- Style preferences
- Apply refactorings one at a time
Make each change independently. Run tests after each step.
- Verify
Run the full test suite. Behavior must be identical.
Rules
- NEVER change behavior — refactoring is structure-only
- Always run tests before AND after
- Make one refactoring at a time, not all at once
- Explain each refactoring: what pattern, why it helps
- If tests don't exist, suggest writing them first
- Don't refactor code that's about to be deleted or rewritten
- Prefer small, reversible changes over large restructurings
