GSD (get-shit-done) is a meta-prompting and context engineering system for Claude Code that imposes software engineering discipline on AI-assisted development. It replaces ad-hoc prompting with a five-step methodology — initialize, discuss, plan, execute, verify — that keeps context fresh and quality high across long, complex projects. The system works by loading specialized documentation strategically: project vision, requirements, roadmaps, and research are injected at the right phases rather than dumped into a single bloated context window. Planning produces XML-formatted task trees with built-in verification steps, and execution happens in waves — parallel where dependencies allow, sequential where they don't. Quality gates automatically detect schema drift, security regressions, and scope creep before they compound into bigger problems. For teams that have experienced the quality degradation that hits around hour three of a long Claude Code session, GSD's architecture of fresh context windows per phase is the fix. A Quick Mode handles ad-hoc tasks without the full planning overhead, making it practical for both exploratory work and milestone-driven development. It's MIT-licensed, JavaScript-based, and designed for solo developers and small teams who want spec-driven development without enterprise process overhead.

marimo-pair is an extension for the marimo reactive Python notebook environment that allows AI agents to join live notebook sessions and interact with a running computational environment in real time. Rather than working in isolation on static code files, agents can execute cells, observe outputs, inspect live data, and iterate — all inside the same notebook session that the human developer is working in. The integration works with Claude Code as a plugin and is designed to be compatible with any tool following the open Agent Skills standard. It has minimal system dependencies (bash, curl, jq) and is built as a lightweight bridge between agent reasoning and live interactive computation. Agents can query the state of the notebook, run new cells, and modify existing ones — making it a powerful environment for data analysis, debugging, and exploratory research. The project is early-stage but points toward an important architectural shift: instead of agents operating on codebases as file trees, they increasingly need to operate on running computational state — especially in data science contexts where understanding a bug means running experiments, not just reading code. marimo's reactive execution model (every cell reruns when its dependencies change) makes it an unusually clean environment for agent-assisted exploration.
Reviewer scorecard
“GSD's five-step workflow (initialize → discuss → plan → execute → verify) with wave-based parallel execution and schema drift detection is the closest thing to a formal engineering discipline for Claude Code projects. The quality gates alone have saved me from shipping broken APIs multiple times.”
“The key insight is that data science agents need to work on running state, not just source files. marimo's reactive model is already the cleanest notebook architecture for reproducibility — adding agents that can execute and observe live cells unlocks a genuinely new debugging and analysis workflow that Jupyter simply can't match.”
“The upfront initialization and thorough planning phase is a real time investment — probably overkill for straightforward CRUD tasks or one-off scripts. GSD shines on complex, multi-milestone projects but adds ceremony that can slow you down when you just need something built quickly.”
“marimo's user base is still a fraction of Jupyter's. This is a cool primitive for early adopters, but most data scientists aren't switching their entire notebook stack to make agents work. The real question is whether marimo gains mainstream adoption — without that, marimo-pair stays a niche tool for a niche tool.”
“GSD is one of the first serious attempts to bring software engineering discipline to AI-assisted development — not just prompting tricks but a reproducible methodology with verification steps and context management. As AI coding scales, the teams with structured workflows like this will outproduce those freewheeling with prompts.”
“Notebooks-as-agent-environments is a compelling framing for the next phase of AI-assisted data science. The reactive execution model means every agent action has deterministic, observable consequences — ideal for building reliable agent workflows on top of messy data. This is what AI-native data tooling looks like.”
“Even as a non-developer building internal tools, GSD's discussion and planning phase surfaces requirements I hadn't thought of before any code gets written. Describing what I want built and watching it execute reliably — with a verify step confirming it actually works — changes how I think about building with AI.”
“For most creative and non-technical users, notebooks with agents inside them adds more complexity than it removes. The value is real for developers and data scientists, but the workflow is still far from accessible enough to benefit people outside that core audience.”
