What are the execution options after a plan is created?

Users can choose between Subagent-Driven execution (fast iteration in the current session) or Parallel Session execution (batch execution with checkpoints).

What is the app-layer skill in Claude Code?

It is a specialized capability for generating detailed, step-by-step implementation plans before coding begins, ensuring architectural consistency and test coverage.

How does it integrate with SuperNavigator?

It automatically indexes plans in the DEVELOPMENT-README.md and allows for easy session resumption using the nav-start command.

How does this skill support Test-Driven Development (TDD)?

It explicitly structures every task around writing a failing test, running it to verify failure, implementing minimal code, and then verifying the pass before committing.

Where are the implementation plans stored?

Plans are saved to the docs/plans/ directory and indexed in .agent/tasks/ for cross-session tracking and OS-layer visibility.

Productivity & Workflow

Generates granular, TDD-driven implementation plans that break down complex features into bite-sized, executable tasks for AI agents.

The app-layer (writing-plans) skill transforms high-level requirements into comprehensive, step-by-step implementation plans designed specifically for AI-driven development. By enforcing Test-Driven Development (TDD), DRY principles, and YAGNI logic, it ensures that even developers or agents with zero codebase context can execute tasks with precision. It integrates deeply with SuperNavigator to index plans for session persistence and provides a clear handoff for subagent-driven or parallel execution, making it indispensable for managing multi-step software engineering workflows within Claude Code.

Key Features
