How does the Overlap Detector calculate similarity?

It uses a weighted scoring system (0-100%) that evaluates title keywords, metadata tags, user story descriptions, technical components, and domain entities.

Where does the skill look for existing project data?

The skill scans the .claude/specs/index.json and .claude/tasks/index.json files in your project root to compare new requirements against current work.

Can it detect overlaps with completed tasks?

By default, it focuses on active statuses like draft and in-progress to prevent immediate work duplication, but it will notify you if a requirement matches a closed or cancelled spec.

What happens if a full duplicate is detected?

The skill will issue an 'ABORT' recommendation, identifying the specific existing specification number and suggesting you update that spec rather than creating a new one.

Productivity & Workflow

Analyzes new requirements against existing specifications and tasks to prevent duplicate efforts and identify architectural overlaps.

The Overlap Detector is a specialized tool for Claude Code that safeguards your development workflow by identifying redundant or conflicting requirements before they become specifications. By analyzing active specs and tasks within the .claude directory, it calculates a weighted similarity score across titles, tags, technical components, and domain entities. This ensures teams avoid wasting effort on duplicate work and maintains architectural consistency by suggesting merges or coordination strategies when partial overlaps are detected.

Key Features

01Detailed overlap classification ranging from related to full-duplicate

02Smart filtering of project specifications based on active or completed status

03Task-level cross-referencing to catch granular overlaps within broader epics

04Automated similarity scoring across technical components and domain entities

05Actionable recommendations for merging requirements or coordinating implementation

Use Cases

01Architectural planning to identify existing modules impacted by new change requests

02Pre-specification audits to ensure a new feature isn't already under development

03Project management optimization by merging overlapping user stories into single work items
