DRY Check

Detect duplicate code across your codebase using jscpd.

Subcommands

Command	Description
`dry` or `dry scan`	Run duplication scan
`dry report`	Show last scan results
`dry config`	Show current jscpd configuration
`dry init`	Create project-specific jscpd.json

Parameters

Parameter	Description	Default
`--threshold N`	Minimum token count for duplicate detection (higher = fewer matches)	jscpd default
`--path <dir>`	Directory to scan for duplicates	Current directory

Examples

# Scan with higher threshold (find only large duplicates)
/bluera-base:dry scan --threshold 100

# 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.
