}| ⚡ DX first Build tools that make daily work faster and calmer. |
🧰 Tooling driven Ship small, composable tools for real workflows. |
🌱 Open source Build in public, learn from users, iterate quickly. |
|
A TypeScript agent harness: AgentKernel, EffectRunner, model bindings (OpenAI / Anthropic / Google), subagents, workflows, interactive TUI chat, and an ACP-compatible server.
|
Multi-framework streaming Markdown renderers for AI apps: Vue/Nuxt, React/Next.js, Svelte, and Angular — progressive Mermaid, Monaco/Shiki code blocks, KaTeX, and low-jitter real-time updates.
|
|
A Vue 3 terminal UI toolkit that renders one component model to browser DOM, CLI stdout, and headless tests — built for agent consoles, streaming markdown transcripts, log viewers, and virtual lists.
|
A project-aware command router for package managers, monorepos, and multi-language dev tasks. Auto-detects npm/pnpm/yarn/bun, fuzzy-runs scripts, and finds commands deep in workspaces.
