Claude Code: New /simplify and /batch Skills to Automate Your PRs
Anthropic introduces two new skills in Claude Code: /simplify for code cleanup and /batch for parallelizable migrations. Together, they automate the path to production.
Boris Cherny, engineer at Anthropic, just announced two new Skills that will change how we use Claude Code daily: /simplify and /batch.
Two Skills, Two Use Cases
/simplify — Automatic Review and Cleanup
The /simplify skill analyzes modified code to identify quality issues:
- Dead code: unused variables, obsolete imports
- Duplication: repeated logic that deserves abstraction
- Complexity: functions too long, nested conditions
- Readability: unclear names, missing comments
Instead of spending 30 minutes reviewing your PR, Claude Code does it for you and suggests improvements directly.
/batch — Parallelizable Migrations
The /batch skill excels at large-scale repetitive tasks:
- Renaming: changing a variable/function name across 50 files
- API migrations: updating calls to a new signature
- Systematic refactors: applying a uniform pattern
The strength of /batch? It parallelizes these operations instead of doing them sequentially. What took 10 minutes now takes 30 seconds.
Complete Automation to Production
Here’s where it gets interesting: combined, these two skills automate much of the work to shepherd a PR to production.
The typical workflow:
- You code your feature
/simplifycleans up the code and suggests improvements- You apply relevant suggestions
/batchcan be used for systematic adjustments- The PR is clean, review-ready, and mergeable
How to Use Them
In Claude Code, simply type:
/simplifyor
/batchClaude Code will analyze your project context and propose appropriate actions.
A Clear Trend
This announcement confirms Anthropic’s direction: transforming Claude Code from a simple assistant into an intelligent automation tool for the development workflow.
Skills are no longer just pre-configured prompts — they become true agents capable of performing complex tasks end-to-end.
Availability
These skills are part of the next version of Claude Code. If you’re already using Claude Code, check for available updates.
