gsd-2
A powerful meta-prompting, context engineering and spec-driven development system that enables agents to work for long periods of time autonomously without losing track of the big picture

GSD-2 is a framework for keeping AI agents on track through long, complex tasks by giving them structured context and spec-driven goals. If you've used AI coding agents and watched them lose the plot halfway through a big refactor, this is the fix.
The core idea is 'context engineering': you define specs that describe what the agent should build, break work into phases, and the framework ensures the agent always has the right information at the right time. Specs look like structured documents with acceptance criteria, constraints, and dependencies. Instead of the agent drowning in its own conversation history, GSD-2 feeds it focused context windows that keep each step scoped and grounded.
The catch: growing fast, but the API is still evolving. Docs are catching up. This is a bet on a concept (structured agent orchestration) rather than a stable production tool. If you need something battle-tested today, look at established agent frameworks. If you want to experiment with the next wave of agent reliability, this is worth watching.
Free vs Self-Hosted vs Paid
fully freeFully open source under MIT. No paid tier, no hosted service. You install it as a development framework alongside your agent setup. The only cost is whatever LLM you run through it.
Free. The framework itself costs nothing; you pay for the LLM APIs it calls.
