What is SpecDev for Claude Code?

SpecDev is a skill that enables a specification-driven development workflow, allowing Claude to manage large, multi-step tasks by breaking them into persistent files.

How does it handle long-running projects?

It stores project state in a .specs/ directory, including plans and task lists, ensuring the AI retains context and progress even if a session ends.

Do I need to manually update the task list?

While you can edit files manually, the skill includes CLI commands that allow the AI agent to update tasks.yaml automatically as it completes its work.

Can I use my own templates with SpecDev?

Yes, SpecDev uses a reference directory with templates for specs, plans, and tasks that can be customized to fit your specific engineering standards.

生产力与工作流

Implements a structured, specification-driven development workflow for AI agents to manage complex, multi-file software tasks across multiple sessions.

SpecDev provides a robust framework for managing complex software engineering tasks by breaking them down into persistent specifications, plans, and task lists. It addresses the challenges of session length limits and context management by creating a dedicated '.specs/' structure that tracks progress and requirements over time. By utilizing a standardized CLI, it allows AI coding assistants to maintain continuity across long-running projects, ensuring that architectural decisions and verification steps are documented and followed consistently from start to finish.
