A printspec is a deterministic, agent-focused specification file that functions like a 3D printer file for software, ensuring any agent reading it produces equivalent working code.

What kind of projects is Spec-Print best for?

It is ideal for projects requiring high consistency, strict state management, and standardized API surfaces, such as backend services, CLI tools, and data-driven applications.

Can I customize the build process after providing a spec?

Yes, you can append natural language guidance using the `--` separator (e.g., `/spec-print myspec.md -- use Postgres`) to apply overrides or amendments to the build.

Does it support automated testing?

Yes, the spec includes a mandatory Test Plan section that enforces a specific implementation order (broken, failure, happy) to ensure software reliability.

How do I generate a specification from my existing project?

You can use the `/spec-print create` command. Claude will explore your codebase, infer logic, and generate a canonical markdown file covering entities, APIs, and business rules.

개발자 도구

Builds or reverse-engineers software using a standardized, deterministic "printspec" format to ensure consistent output across AI agents.

Spec-print introduces a rigorous methodology for software creation by treating requirements like 3D printer files. By utilizing a "printspec," developers ensure that any AI agent reading the specification produces equivalent, production-grade software regardless of the environment. This skill allows users to either "print" entire applications from a strict markdown-based spec or reverse-engineer existing codebases into a canonical document that defines entities, state machines, API surfaces, and design systems with absolute precision.
