Subcommands
| Command | Description |
|---|---|
dry or dry 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)

# 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.
