Geniffy

Geniffy for OpenCode

OpenCode that remembers you and your projects. Each session starts with what Geniffy knows that matters here, and what you discuss is saved as you go: every fact with the line it came from, and a plain "nothing stored" instead of a guess.

Install

Add the plugin to opencode.json, in your project or in ~/.config/opencode/ for every project:

{
  "$schema": "https://opencode.ai/config.json",
  "plugin": ["opencode-geniffy"]
}

OpenCode installs it the next time it starts. Then two sign-ins, each one click in the browser, with no key to copy:

1. The memory tools. Run opencode mcp auth geniffy, sign in to Geniffy and choose Allow.
2. Automatic memory. Type geniffy login in a chat. Your browser opens on Geniffy; choose Allow.

The plugin runs inside OpenCode, so there is nothing else to install.

What it does

When	What happens
OpenCode starts	The Geniffy memory tools join your config (unless you already have a server named geniffy)
A session starts	Its system prompt opens with a short summary: what lasts about you, what is going on now, and what was said before about this project
You send a message	It is kept until the turn ends
The session goes idle	The exchange is saved to Geniffy in the background, who said what kept, so your words become facts about you and the model's do not

Geniffy learns the facts in each exchange and keeps each one with the line it came from and when it was said. A newer fact replaces an older one, and when nothing supports an answer, the model is told to say so.

Commands

Type these in a chat. The plugin answers them itself (the answer shows as a notice), and they are never saved.

Command
geniffy login	Sign in for automatic memory (once per computer)
geniffy status	Whether you're signed in, whether saving is on, and what was saved last
geniffy pause, geniffy resume	Stop or restart saving. Sessions still start with what Geniffy remembers
geniffy logout	Sign out on this computer

What stays on your computer

• Secrets. API keys, tokens, passwords, connection-string passwords and private keys are removed before anything is saved, matched by shape (sk-…, ghp_…, AKIA…, xoxb-…, password: … and more).
• Code. Code blocks are left out: your repository holds your code, and the memory holds what was decided.
• Commands. The Geniffy commands aren't saved.
• Everything, while paused. geniffy pause stops saving until you resume.
• The sign-in itself lives in ~/.geniffy/opencode/, readable only by you. geniffy logout ends it at Geniffy and deletes it here.

One memory, in every app

This is the same memory you can connect to Claude Code, Claude.ai, ChatGPT, Cursor, VS Code and Codex through the Geniffy MCP server. See it, correct it or erase it at geniffy.com/app.

Develop

npm test     # node --test, no dependencies

Set GENIFFY_API_URL to point the plugin at another Geniffy server, and GENIFFY_PLUGIN_HOME to keep its files somewhere other than ~/.geniffy/opencode.
