Does this skill actually write code?

Yes, in Phase 4 (Implement), the skill executes the tasks generated in previous phases, writes the code, and validates it against the defined acceptance criteria.

What if my project doesn't have a constitution file yet?

Phase 0 of the workflow will automatically detect the absence of a .constitution.md file and help you generate one based on your project principles.

What is the INVEST score gate in Phase 1?

It is a quality check that ensures requirements are Independent, Negotiable, Valuable, Estimable, Small, and Testable (INVEST) with a score of 7 or higher before proceeding.

Can I resume a workflow if the session is interrupted?

Yes, the skill maintains checkpoints. You can use the --resume flag to pick up exactly where the workflow left off.

Productivity & Workflow

Executes the complete 5-phase Spec Kit workflow to transform feature requests into validated, production-ready code.

This skill orchestrates the end-to-end GitHub Spec Kit methodology, guiding developers through a rigorous process of defining project principles, generating canonical specifications, creating implementation plans, and executing tasks. It ensures high-quality output by enforcing strict validation gates at every stage—such as INVEST score minimums for requirements and comprehensive acceptance criteria checks—making it an essential tool for teams that prioritize structured development, architectural consistency, and traceable implementation logic.

Key Features

01Automated quality gates including INVEST score validation and requirement mapping.

02Persistent progress tracking with checkpointing for workflow resumption and rollbacks.

03Comprehensive artifact generation including specifications, design docs, and completion reports.

0438 GitHub stars

05Integrated agent orchestration using specialized processors and reviewers for each phase.

06Full 5-phase lifecycle automation: Constitution, Specify, Plan, Tasks, and Implement.

Use Cases

01Developing complex features that require rigorous architectural planning and specification before coding.

02Standardizing development workflows across a team using the Spec Kit methodology for consistency.

03Managing long-running implementation tasks with built-in checkpoints and automated validation.
