FAQPage Schema
How do I automate feature development with codebase intelligence and security checks?

Automated feature development uses a sealed plan and signoff authorization to generate code, apply tests, and validate security. By analyzing your repository, it ensures robust code is produced before merging.

What is a sealed plan and signoff authorization for feature planning?

A sealed plan is a JSON file defining the feature scope, while signoff authorization grants approval to proceed. Consuming these inputs ensures automated implementation follows approved specifications.

Do I need GitHub access for automated codebase analysis and security checks?

Yes, GitHub access is required for repo-backed analysis. This enables the system to perform in-depth codebase intelligence analysis and execute security checks directly against your repository.

How do I build a new feature from a sealed plan using Python and Git?

Provide a sealed plan JSON and signoff file to the skill. It handles feature planning, implementation, testing, and validation using Python and Git dependencies to produce ready-to-review code.

Can I use automated feature development for CI/CD pipelines?

Yes, automated feature development integrates with CI/CD workflows by performing testing and security validation. It ensures code passes security checks and is ready before code review and merging.
