End Agent Amnesia

Every Claude Code and Cursor session starts from scratch. Your agent re-reads your architecture, your conventions, your past debugging sessions. We tracked one developer spending 99.4% of 100 million tokens just on context re-loading.

That’s not AI working. That’s AI starting over.

The Problem with Stateless Agents

Modern coding agents are brilliant — when they have context. The problem is they’re stateless by design. Every new session, they read your codebase from scratch, infer your conventions from your files, and rebuild their mental model from zero.

This has three costs:

  1. Token cost — You’re paying to re-read the same files every session
  2. Time cost — The agent spends the first minutes of every session catching up
  3. Quality cost — Without memory of past decisions, agents repeat mistakes

How Nexus Fixes It

Nexus Prime is a local-first memory layer that sits between your coding agents and your filesystem. It intercepts what your agents learn during a session and stores it in local SQLite — architecture decisions, file conventions, debugging patterns, active worktrees.

Next session, the same context surfaces automatically. No re-reading. No re-explaining.

npm i -g nexus-prime
nexus-prime setup claude
nexus-prime start

The Numbers

Early users report:

  • 7.8× token compression — the same work with a fraction of the input tokens
  • 62% cost reduction — a Series B fintech cut Claude Code spend in week one
  • 24× faster memory access — SQLite lookups vs full codebase re-reads

Local-First by Design

We made one architectural decision that everything else follows from: all data stays local.

No cloud sync. No vector database subscription. No API keys beyond your existing agents. Your codebase lives on your machine — so does your memory.

This isn’t just a privacy choice. It’s faster. A local SQLite lookup takes microseconds. A cloud round-trip takes hundreds of milliseconds, every session start.

What’s Next

We’re working on team memory sync (Pro Power), where architectural decisions propagate across every developer on your team automatically. One engineer documents a pattern — every agent on the team knows it.
