SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Genera una línea base de especificaciones OpenSpec a partir del código existente, leyendo src/, README.md y AGENTS.md para deducir el comportamiento actual y archivándola como un change llamado "baseline" sin aplicar cambios al código.

Core Features & Use Cases

Inversión de ingeniería para producir artefactos de OpenSpec (proposal.md, design.md, specs/, tasks.md) y archivarlos directamente como baseline.
Flujo guiado para identificar directorios fuente, proponer cambios, y archivar sin phase de apply, con revisión manual posterior si es necesario.
Uso típico: proyectos con código y documentación pero sin especificaciones OpenSpec, que desean una referencia histórica reproducible.

FAQPage Schema

How do I generate an OpenSpec baseline from an existing codebase?▼

The skill reverse-engineers your existing source code and documentation to produce OpenSpec spec artifacts including proposal.md, design.md, specs/, and tasks.md, then archives them directly as a baseline change without applying code modifications.

What does reverse-engineering a codebase into OpenSpec specifications involve?▼

Reverse-engineering into OpenSpec involves reading your src/, README.md, and AGENTS.md files to deduce current software behavior, generating a reproducible historical reference containing proposal, design, specs, and tasks artifacts.

Do I need the openspec CLI to create and archive a baseline?▼

Yes, creating and archiving a baseline requires the openspec CLI, an openspec/config.yaml file, and the opsx:propose plus opsx:archive skills to execute the proposal generation and archival steps.

Can I generate OpenSpec artifacts for projects that only have source code and documentation?▼

Yes, you can generate OpenSpec artifacts for projects containing source code and documentation but lacking existing OpenSpec specifications, across all languages supported by OpenSpec, creating a reproducible baseline reference.

Does archiving an OpenSpec baseline modify my existing source code?▼

No, archiving an OpenSpec baseline does not modify your source code; it generates and archives the deduced specifications as a change named baseline, skipping the apply phase to allow manual review afterward.
