Fission-AI/OpenSpec

OpenSpec is a command-line interface and core library for managing software specifications and changes through an artifact-driven workflow. It provides a unified CLI for creating, validating, and archiving changes, while generating structured instructions for over 20 AI coding assistants and IDEs. The system enforces schema integrity via runtime validation and manages a local store of specifications, supported by shell completions and interactive prompts.

This period focused on a comprehensive overhaul of the OpenSpec CLI and core architecture, introducing a unified command-line interface with shell autocompletion and global configuration support. The team implemented robust validation using Zod schemas, refactored the template system into a modular skill-based architecture, and introduced an artifact graph for dependency tracking. Extensive test coverage was added across parsers, commands, and utilities to ensure stability.

This period focused on building out the platform's core infrastructure, introducing a new store system, a generic command-generation framework for 20+ AI coding tools, and a searchable multi-select prompt. It also included the launch of the OpenSpec documentation site and comprehensive test coverage for these new modules.
