Does this skill write the actual implementation code?

No, this skill focuses exclusively on creating the plan. Once the plan is finalized, you can invoke an implementation skill to write the actual code based on the plan's instructions.

How does this differ from the brainstorming skill?

Brainstorming focuses on the 'what' (requirements, scope, and decisions), while Technical Planning focuses on the 'how' (specific file paths, architecture, and subtasks).

Why are test files mandatory in the generated plans?

Including test files ensures that every feature subtask is verifiable and follows a test-driven approach, preventing the AI from skipping test coverage during the implementation phase.

Can I use this with an existing PRD?

Yes, the skill is designed to ingest existing PRDs or design documents to generate a high-quality, executable technical plan.

What is the Technical Planning skill?

It is a specialized capability for Claude Code that takes requirements and creates a structured, file-specific roadmap for developers or AI agents to implement features accurately.

Productivity & Workflow

Transforms product requirements into structured, executable technical implementation plans with clear dependencies and test scenarios.

The Technical Planning skill bridges the gap between high-level requirements and implementation by creating a detailed roadmap for Claude to follow. It automates the process of identifying affected files, making architectural decisions, and breaking down features into atomic, commit-sized subtasks. By ensuring every task includes explicit test paths and rationale, it provides a zero-context blueprint that enables seamless code generation while maintaining codebase consistency and quality. This skill is ideal for moving from a PRD to a concrete set of developer tasks without manual decomposition.
