Can I use the output with other tools?

Yes, it outputs a standardized feature_list.json designed specifically for integration with state trackers and autonomous implementation agents.

How many features does it generate?

It is optimized to generate between 50 and 100+ atomic features to ensure comprehensive coverage of even complex project requirements.

What input does AC Spec Generator require?

It typically takes a parsed project specification and transforms it into a structured feature list compatible with autonomous implementation workflows.

How does it handle feature prioritization?

The skill identifies critical dependencies first to establish a foundation, then assigns priority levels from Critical to Low based on core functionality needs.

Productivity & Workflow

Generates comprehensive, testable feature lists from project specifications to accelerate autonomous development workflows.

About

AC Spec Generator bridges the gap between high-level project requirements and actionable code implementation by decomposing specifications into atomic, testable units. It automatically generates detailed feature lists—often exceeding 100 items—complete with acceptance criteria, priority levels, and effort estimates. This provides a structured, machine-readable roadmap in JSON format that allows Claude or other autonomous agents to implement complex projects with high precision and full test coverage.
