code-simplifier is agent-read markdown (skill) from openhands/extensions: Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Analyzes recently modified code across three dimensions - code reuse, code quality, and efficiency - and provides actionable improvement suggestions. This skill should be used when the user asks to "simplify code", "refine code", "clean up code", "improve code quality", or requests a simplification review of recent changes..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Code Simplifier
Analyze recently modified code and suggest refinements that improve clarity, consistency, and maintainability - without changing what the code does. The review covers three complementary aspects:
1. **Code Reuse** - Eliminate duplication, consolidate shared logic, leverage existing utilities.
2. **Code Quality** - Improve naming, reduce complexity, enforce project standards from `AGENTS.md`.
3. **Efficiency** - Fix algorithmic issues, remove unnecessary work, optimize resource usage.
## Review Process
### Identify the Scope
By default, focus on recently modified code. Use `git diff` or the file list from the current PR/MR to determine the changed files. When the user specifies a different scope, follow their instruction:
- **Specific files**: "simplify `src/auth.py`" - review only the named files
- **Directory**: "simplify the `utils/` folder" - review all files in that directory
- **Full repo**: "simplify the whole project" - review the entire codebase
- **PR/MR**: "simplify this PR" - review only files changed in the current PR/MR
### Sub-Agent Delegation (Preferred)
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
