Parameters

ParameterDescriptionDefault

# Scan specific directory
/​bluera-base:dry scan --path src/

# Combine both
/​bluera-base:dry scan --threshold 75 --path lib/

Workflow

Phases: Check jscpd → Scan codebase → Report duplicates → Suggest refactors

1. Check jscpd Installation

command -v jscpd || npx jscpd --version

If not installed, suggest: npm install -g jscpd

2. Run Scan

jscpd --reporters json --output .bluera/​bluera-base/​state/ .

3. Parse Results

Results are stored in .bluera/​bluera-base/​state/​jscpd-report.json

4. Refactoring Guidance

See skills/​dry-refactor/​SKILL.md for language-specific refactoring patterns.
