About

Context Nine is a collection of developer tools for carrying coding-agent work and project context across machines. Its public launcher installs pinned releases of independently versioned components and verifies their integrity. The tools cover code-folder synchronization, shared agent skills and instructions, and an Obsidian-oriented context workspace for organizing project knowledge. Developers can select the components that fit their workflow and use them alongside coding agents across Mac and Linux systems. The toolkit is intended for software engineers and teams running coding agents on multiple machines. Some hosted integrations are private; the public launcher is released under the MIT license.

About

Subspace is an AI-native agent workspace designed to help developers and teams manage, coordinate, and collaborate with multiple coding agents in a single unified environment while preserving context across sessions. Instead of treating each AI interaction as isolated, the platform builds persistent memory in the background by compressing every conversation into structured observations such as decisions, blockers, and progress, which are continuously synthesized into a clear, evolving project state. This shared memory belongs to the workspace rather than any individual tool, allowing different agents like Claude Code, Codex, or others to seamlessly pick up where previous sessions left off without requiring repeated explanations or manual context transfer. Subspace integrates terminals, files, documentation, browser views, and git workflows into organized workspaces, enabling users to run multiple agents side by side and switch between projects almost instantly.
