## Description
Self-improving learning engine for Claude Code. Extracts signals from every session (corrections, successes, confusion), runs periodic reflections, and evolves behavioral frameworks through evidence tiers (hypothesis → observed → validated). Frameworks that keep working get promoted, bad ones get retired. 9 MCP tools, automatic hooks, phase-adaptive learning. Single dependency, local-only. npx claude-soul init --starter
## Claude Desktop Quick Installation
Install path detected from listing signals. Uses `npx` (confidence: high):
```json
"mcpServers": {
"claude-soul": {
"command": "npx",
"args": ["-y","claude-soul"]
}
}
```

> Claude Code forgets everything between sessions. Claude Soul doesn't.
```bash
npx claude-soul init --starter
```
One command. No API key, no cloud, everything local.
**Prerequisites:** Node.js >= 18, Claude Code (Pro or Max plan).
## Three things it does
### 1. Remembers across sessions
Cross-session memory with semantic search. Facts, decisions, lessons — all searchable by meaning, not just keywords. Uses local SQLite + optional [Ollama](https://ollama.com) embeddings.
```
You: "what did we decide about the auth flow last week?"
Claude: [searches memory → finds the decision, context, and reasoning]
```
### 2. Tracks your corrections
Every time you correct your Claude — "that's wrong", "you missed this", "stop doing that" — the system detects the pattern, classifies it, and tracks whether it's getting better or worse.
```bash
$ claude-soul shadow --brief
premature_done: 26 corrections across 10 sessions ↑ [active]
robot_mode: 7 corrections across 6 sessions ↓↓ [internalized]
authenticity: 5 corrections across 5 sessions ↓↓ [internalized]
```
Patterns move through lifecycle stages: **new → active → improving → internalized**. After 200 sessions of real data: `robot_mode` went from 0.8 corrections/session to zero.
### 3. Develops judgment over time
The system extracts behavioral signals from every session and periodically reflects on them. Frameworks that keep working get promoted. Bad ones get retired. After a few weeks, you get a Claude that pushes back on bad ideas, catches its own confabulation, and develops techniques you never prompted.
## Install
### Quick start (no extra dependencies)
```bash
npx claude-soul init --starter
```
Add this to your CLAUDE.md:
```markdown
## Soul System
Call `soul_context()` at the start of every conversation.
Use `soul_reflect` when you have idle time.
```
Done. Memory works with keyword search, everything else runs automatically.
### With semantic memory
Semantic search finds memories by meaning — "auth decision" finds a memory stored as "chose JWT tokens for login." Without it, search is keyword-based (still works, just less flexible).
```bash
# 1. Install Ollama (https://ollama.com)
# 2. Pull the embedding model
ollama pull nomic-embed-text
# 3. Then install as usual
npx claude-soul init --starter
```
The system auto-detects Ollama. No configuration needed.
### For agents (non-interactive)
```bash
npx claude-soul init --starter --skip-identity
```
Skips the name/context questions. Add the CLAUDE.md snippet to your agent's working directory and it works the same way — memory, correction tracking, and framework evolution all run through Claude Code's hooks and MCP server regardless of whether a human is typing or an agent is running.
### Already installed? Upgrade
```bash
npm install -g claude-soul@latest
claude-soul upgrade
```
Your soul files, frameworks, and data stay untouched. The upgrade re-registers hooks and MCP server with the latest version and adds any new features.
After upgrading, run `claude-soul index` once to backfill existing data into the memory system.
What's new in v0.2
- **Memory system** — 6 new MCP tools (`memory_save`, `memory_search`, `recall`, etc.) for cross-session fact storage with semantic search
- **Correction tracking** — auto-detects when you correct your Claude and classifies the pattern
- **Shadow analysis** — `claude-soul shadow` shows behavioral patterns with trend arrows and lifecycle stages
- **Indexing** — `claude-soul index` loads your existing journals and soul files into the memory database
CLI commands
These are optional — the system runs automatically. The CLI is for inspecting collected data from your terminal.
| Command | What it does |
|---------|-------------|
| `claude-soul status` | System health — frameworks, signals, phase |
| `claude-soul shadow` | Your correction patterns with trends |
| `claude-soul shadow --generate` | Auto-generate a SHADOW.md from your data |
| `claude-soul index` | Index existing files into memory database |
| `claude-soul upgrade` | Update hooks without touching your data |
## How it works
```
Session N
│
├─ Load identity + frameworks + memory
│
├─ Normal Claude Code usage
│
├─ Session ends → extract signals + corrections + index to memory
│
└─ Reflection threshold? → evolve frameworks → Session N+1
```
Everything runs through Claude Code's official extension points: an MCP server (15 tools) and hooks (signal extraction, journaling, memory indexing, correction tracking).
MCP Tools (15 total)
**Identity & Learning**
| Tool | Purpose |
|------|---------|
| `soul_context` | Load identity + frameworks + state at session start |
| `soul_activate` | Select relevant frameworks for current conversation |
| `soul_framework` | Load a single framework with full evidence history |
| `soul_signal` | Record observed interaction patterns |
| `soul_reflect` | Trigger a reflection cycle (quick/deep/meta) |
| `soul_self_evaluate` | Record a self-evaluation of a complex response |
| `soul_read` | Read soul files (SOUL.md, SHADOW.md, etc.) |
| `soul_write` | Write to user-editable soul files |
| `soul_status` | Get current system status |
**Memory**
| Tool | Purpose |
|------|---------|
| `memory_save` | Save facts, decisions, or lessons |
| `memory_search` | Semantic search across all memories |
| `memory_journal` | Search or browse conversation journals |
| `memory_recent` | List recently saved memories |
| `memory_stats` | Memory system statistics |
| `recall` | Unified "ask anything about the past" search |
Soul files (in ~/.soul/files/)
| File | Purpose | Managed by |
|------|---------|-----------|
| `SOUL.md` | Your identity — who you are, how you work | You + Claude |
| `SHADOW.md` | Blind spots and behavioral tendencies | You + Claude |
| `STORY.md` | Timeline of growth and key moments | You + Claude |
| `CORRECTIONS.md` | Patterns to avoid, learned from mistakes | You + Claude |
| `STATE.md` | System telemetry (confidence, phase, counts) | Auto |
| `FRAMEWORKS.md` | Active framework index | Auto |
Configuration
All settings in `~/.soul/config.json`:
```json
{
"signals": { "enabled": true, "maxLogSizeKb": 50 },
"reflection": {
"enabled": true,
"quickSignalThreshold": 20,
"deepSignalThreshold": 100,
"quickModel": "haiku",
"deepModel": "sonnet"
},
"contextBudget": { "maxTokens": 4500 },
"tensions": { "enabled": true },
"metaOptimization": { "enabled": true },
"writeProtection": { "enabled": true }
}
```
## Philosophy
1. **Evidence over assertion** — Frameworks earn their place through repeated confirmation.
2. **Local-first** — No cloud, no accounts, no telemetry.
3. **Invisible when working** — Extracts signals automatically, reflects in the background.
