I got tired of re-explaining context to my AI every single prompt. It forgets what it did 5 minutes ago. It stops after one step and waits. You end up
babysitting it more than coding yourself.

So I built Long-Horizon — a skill that turns any AI coding tool into an autonomous agent with a persistent graph memory.

What it does

1. You give it one task — "Build a REST API with auth"
2. It decomposes into subtasks and executes them in a loop — no prompting between steps
3. It writes knowledge to disk as a connected graph — decisions, lessons, patterns, all linked
4. It resumes perfectly after any interruption — reads its own state and picks up exactly where it stopped

The graph brain

Every decision, lesson, and pattern becomes a node. Nodes connect via typed edges (leads_to, caused_by, learned_from). Over time, the AI builds a web
of project knowledge it can traverse for context.

Live viewer

Real-time cyberpunk visualization that shows the brain growing as the AI works:

• Neon glowing nodes with particle trails along edges
• Unlimited zoom/pan — scroll to zoom, drag to navigate
• Sound effects when new nodes appear
• Runs on localhost:3333

Zero dependencies, ~38KB

No vector DB. No cloud. No API keys. Pure Node.js, filesystem only. Works offline.

Works with everything

One command installs for your tool:

npx long-horizon init

  npx long-horizon adapt cursor    # or: windsurf, claude, aider, codex, all

  

Also ships an MCP server with 11 tools for direct AI integration.

It's always-on

Once installed, you don't need to say "use Long-Horizon" or prefix your prompts. The AI reads the skill file and operates autonomously by default. Just
talk normally:

Build a user dashboard with charts and dark mode.

The AI loops until done.
