OpenSpec: Spec-driven development (SDD) for AI coding assistants.
What problem it solves
AI coding assistants can produce unpredictable results when requirements exist only in chat history. OpenSpec adds a lightweight specification layer so people and AI assistants can align on what to build before implementation begins.
Key features
Agree Before Building — People and AI assistants can align on requirements before code is written, making the intended change reviewable up front.
Source: README
Organized Change Artifacts — Each change has its own folder containing a proposal, specifications, design, and implementation tasks.
Source: README, openspec
Fluid, Iterative Workflow — Artifacts can be updated at any time without rigid phase gates, supporting an iterative approach to development.
Source: README
Multi-Tool Assistant Support — The project provides slash-command workflows for a wide range of AI coding assistants and prints the appropriate command form for selected tools.
Source: README
Plain Markdown Specifications — Requirements are expressed in ordinary Markdown with concrete scenarios, avoiding a separate specification syntax.

Quick start
Copied verbatim from the project's README.
curl -fsSL https://openspec.dev/cli/install.sh | shcd your-project
openspec initWho it may suit
Inference: OpenSpec may suit developers and teams using AI coding assistants who want to plan changes in specifications before implementation, including teams working across multiple repositories.
Topics to discuss
How should shared specifications evolve when multiple teams and coding agents consume them?
Which workflow artifacts and validation rules should be included in community schemas?
How can teams adopt specification-driven development in existing repositories without disrupting their current practices?
