How do I install the Dry Refactor skill?

Run npx skillmds@latest add majiayu000/dry-refactor-3 in your terminal (requires Node.js), paste this page's agent-chat prompt into Claude, Cursor, or any MCP-connected agent, or download the SKILL.md file and copy it into your agent's skills directory.

Is Dry Refactor safe to use?

This skill has not completed SkillMD's automated safety review yet. Independent scanners report: SkillSpector: PASS, Skill Scanner: PASS. Capability flags: docs only. SkillMD never runs a skill's scripts for you; review the SKILL.md before installing.

Which AI agents work with Dry Refactor?

This skill is tagged as working with Claude Code, Claude.ai, OpenAI Codex. SKILL.md is an open format, so most agents that read a skills directory can load it too.

Is Dry Refactor free to use?

Yes. Installing skills from SkillMD is free, and the skill stays under its author's original license.

DRY Refactoring Guide

Help users eliminate code duplication by extracting shared logic into reusable modules.

When This Applies

User mentions "duplicates", "DRY", "repeated code", "copy-paste"
/bluera-base:dry scan found duplicates that need refactoring
Code review identified similar patterns across files

When Duplication is Acceptable

Not all duplication is bad. Keep duplicates when:

Test code: Explicit test cases can repeat for clarity
Generated code: Don't DRY generated files
Incidental similarity: Coincidentally similar code that may diverge
Coupling cost: Extraction would create tight coupling between unrelated modules

Refactoring Workflow

1. Analyze the Duplicates

# Run scan if not already done
/bluera-base:dry scan

# Review the report
/bluera-base:dry report

2. Categorize Each Duplicate

Category	Action
Exact copy	Extract immediately
Near-duplicate	Parameterize differences, then extract
Structural	Consider codegen/templates
Coincidental	Leave as-is, document why

3. Choose Extraction Target

Scope	Target
Same file	Local function/method
Same module/package	Shared utility file
Across modules	New shared module
Across repos	Shared library/package

4. Execute Extraction

Create the shared abstraction
Move one instance, verify tests pass
Replace remaining instances
Update imports/exports
Run tests after each replacement

5. Validate

All tests pass
No circular dependencies introduced
Public API unchanged (if applicable)
Code is actually simpler (not over-abstracted)

Anti-patterns to Avoid

Wrong abstraction: Forcing unrelated code together
Over-parameterization: Too many config options
Premature extraction: Extracting before patterns stabilize
Leaky abstraction: Exposing implementation details

Language-Specific Patterns

See @dry-refactor/references/patterns.md for detailed examples:

Language	Primary Pattern
JS/TS	Module export, barrel index
Python	Module with init.py
Rust	Submodule with pub use
Go	Same-package separate file

Report Integration

When /bluera-base:dry scan identifies duplicates:

Review the report at .bluera/bluera-base/state/dry-report.md
Start with highest-impact duplicates (most tokens/instances)
Use suggested extraction targets from the report
Re-run /bluera-base:dry scan after refactoring to verify reduction
