spec-driven-development
Intent-First Agentic Development Language.
Clear is a programming language where your specification and implementation are the same file. If you can describe what it should do, you have already written it.
Production-grade engineering skills for AI coding agents.
Skills encode the workflows, quality gates, and best practices that senior engineers use when building software. These ones are packaged so AI agents follow them consistently across every phase of development.
A toolkit for spec-driven software development. Stop writing prompts, start writing specs. Ship better quality software and minimize slop.
LLM-native spec language. Velocity through clarity.
Give your AI agents something more useful than a prompt.

Architecture in. Software out. Spec-Driven Code Generation.
An open-source framework that turns architectural specs into working code. You write a specification, optionally lay out the architecture, and Ossature breaks it down into a build plan that gets executed step by step with an LLM doing the code generation under tight constraints. The specs are your source of truth, you review the plan before anything gets built, and when something breaks you fix that step and keep going instead of starting over.

Solves context rot — the quality degradation that happens as Claude fills its context window.
Contracts before code. Tests as law. Agents that can't cheat.
Pact is a multi-agent software engineering framework where the architecture is decided before a single line of implementation is written. Tasks are decomposed into components, each component gets a typed interface contract, and each contract gets executable tests. Only then do agents implement -- independently, in parallel, even competitively -- with no way to ship code that doesn't honor its contract. Generates Python, TypeScript, or JavaScript.

Build high-quality software faster.
An effort to allow organizations to focus on product scenarios rather than writing undifferentiated code with the help of Spec-Driven Development.
Spec-Driven Development flips the script on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: specifications become executable, directly generating working implementations rather than just guiding them.
