# mem-forever

Keeps your preferences and decisions in .ilang/ inside a private repo, so a new session no longer starts from zero.

## What it does

The plugin gives an agent a memory that outlives the session. A conversation turns into two files: `soul.md` holds the behavioural profile, `memory.md` collects decisions and lessons. Both sit in `.ilang/` and get updated for you.

Memories are written as iLang text structures. You can read them, diff them with `git diff`, and carry them to another tool — nothing ties them to one vendor. Setup is short: create a private repo from the template, open it in any AI tool, answer a few questions. After that the profile sharpens itself through mutation and decay rules.

You need your own GitHub repo, and private is the sensible choice — `soul.md` collects how you like to work. Moving to another project takes one sentence with the repo address and a personal access token. For separate contexts, run the template again: each repo becomes its own memory.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-community
```
In the agent chat (not a shell):
```text
/plugin install mem-forever@claude-community
```

## When to use it
- rebuild working context after switching sessions or models
- store output preferences once instead of restating them
- keep a log of decisions and lessons learned
- move accumulated memory between different AI tools
- keep personal data in your own repo with no third-party server

## Example prompts
- My memory repo is at `https://github.com/YOU/mem-forever`, PAT `ghp_xxx`. Clone it, read `.ilang/soul.md` and `.ilang/memory.md`, then come back here.
- Save to memory that I want conclusions first, details only if I ask.
- Update `soul.md` based on this session.

# Mem-Forever

> **永久记忆 · 跨会话 · 跨模型**
> A persistent memory layer for AI agents, built on the iLang protocol.
>
> iLang is the first protocol to formally map Greek mathematical symbols (Σ, Δ, φ, λ, Ω, ∇, μ, Π, ψ, ξ, ζ, θ, ∂) as primitive verbs for AI-to-AI communication, and the first to define a computable vector space for AI judgment (11 dimensions, 4 axioms, fuzzy-mathematical foundation).

## Abstract

Every AI tool forgets you after every session. You close a window, and your preferences, decisions, and lessons vanish. Next session, you start from zero.

**Mem-Forever** is a Git-native memory layer that lets any AI agent remember you permanently. Memories are stored as compact iLang structures in your own private repo, readable by humans, parseable by machines, and portable across every tool.

Where context windows forget, **Mem-Forever endures**.

---

## Why

| | |
|---|---|
| **Persistent** | One memory, surviving every session and every model swap. |
| **Portable** | Plain-text iLang shards in `.ilang/`. `git diff`-able, no vendor lock-in. |
| **Automatic** | AI builds your profile from conversation. You never fill a form. |
| **Private** | Your repo, your data. No server, no account, no telemetry. |

---

## Quick Look

```
.ilang/
  soul.md      ← who you are (auto-generated from conversation)
  memory.md    ← what you decided, learned, built (auto-appended)
```

```ilang
::DNA{user}
::CORE{
  ::CONTEXT{role:fullstack_dev|experience:10yr}
  ::GENE{style|conf:confirmed}
    T:conclusions_first
    T:minimal_output|when:simple
    A:verbose_without_signal⇒waste
}
::LESSONS{
  ::LESSON{id:serverless_no_shared_state|conf:confirmed}
}
```

Every preference is **addressable**, **scoped**, **versioned**, and **falsifiable**.

---

## Setup (seconds)

**Step 1**   Click **"Use this template"** → **Create a new repository** → Set to **Private**.

**Step 2**   There is no step 2.

Open the repo with any AI tool. It reads the instruction files, asks you a few questions, builds your profile. From that point on, it remembers.

## Works With Everything

| Tool | Auto-reads | How |
|---|---|---|
| Claude Code | `CLAUDE.md` | Open repo, start working |
| Cursor | `.cursorrules` | Open repo, start working |
| Codex | `AGENTS.md` | Open repo, start working |
| Copilot | `.github/copilot-instructions.md` | Open repo, start working |
| Gemini CLI | `GEMINI.md` | Open repo, start working |
| ChatGPT | Project knowledge | Upload `soul.md` |
| Claude.ai | Project knowledge | Upload `soul.md` |
| Gemini web | Google Drive | Sync `soul.md` to Drive |

### Working on a different project?

One sentence restores full context:

> *My memory repo is at `https://github.com/YOU/mem-forever`. PAT: `ghp_xxx`. Clone it, read `.ilang/soul.md` and `.ilang/memory.md`, then come back here.*

### Multiple projects?

Use this template again. `mem-forever-work`, `mem-forever-research`, `mem-forever-client-x`. Each repo is an independent memory. Same engine, different context.
