## The Forgetting Problem

Claude starts fresh every session. Solutions you found, architectures you designed, bugs you debugged — all gone.
Context retention drops below **20% after 10 sessions**. CSR fixes this with a single binary that gives Claude perfect memory.
No special syntax. No commands. Install once, and past context appears automatically when you need it.

## One Binary. 44MB.

Everything runs locally in a single process. No Docker, no database server, no API keys required.
- **SQLite** — storage for chunks, embeddings, enrichment state
- **HNSW** — sub-millisecond vector search (<1ms p95)
- **FastEmbed** — 384-dim local embeddings
- **AST** — code-aware search across 6 languages
**6 hooks** fire across the session lifecycle. **12 MCP tools** for explicit search.

## The Pipeline

<img align="right" src="docs-site/public/images/card-03-pipeline-light.png" alt="The Pipeline — 3 layers, 9.3x improvement" width="420" />
</picture>
</a>
Three layers progressively improve search quality from raw chunks to AI-enriched narratives — **9.3x improvement**.
Higher quality context. Better decisions. Fewer tokens.

## Install
```bash
curl -fsSL https://raw.githubusercontent.com/ramakay/claude-self-reflect/main/scripts/install.sh | sh
```
One command. Downloads the binary, runs setup, registers MCP server, installs 6 hooks. Restart Claude Code.
| Platform | Support |
|----------|---------|
| macOS (Apple Silicon) | Prebuilt binary |
| Linux x86_64 / WSL | Prebuilt binary |
| Linux ARM64 | Prebuilt binary |
| macOS (Intel) | Build from source |
<details>
<summary>Alternative: npm</summary>
```bash
npm install -g claude-self-reflect
```
</details>
<details>
<summary>Build from source</summary>
```bash
git clone https://github.com/ramakay/claude-self-reflect.git
cd claude-self-reflect/csr-engine
cargo build --release
cp target/release/csr-engine ~/.local/bin/
csr-engine setup
```

<summary><strong>What You'll Ask</strong> — after install, just ask Claude naturally</summary>
- *"How did we solve re-renders on this component?"*
- *"What did we tell Joe about that commit?"*
- *"What were our frustrations with this approach?"*
- *"Where did we put the auth middleware config?"*
No special syntax. No commands. CSR finds relevant past context and injects it automatically.

<summary><strong>Performance</strong> — sub-millisecond search, 93ms startup</summary>
| Metric | Value |
|--------|-------|
| **Cached startup** | 93ms |
| **Search latency (p95)** | <1ms |
| **Binary size** | 44MB |
| **Import speed** | ~20 conversations/sec |
| **Embedding** | 0.73ms/text (batch) |
</details>
<details>
<summary><strong>MCP Tools</strong> — 12 annotated tools available to Claude</summary>
All tools include [MCP tool annotations](https://spec.modelcontextprotocol.io/specification/2025-11-05/server/tools/#annotations) so Claude Code understands their safety characteristics.
| Tool | Description | Safety |
|------|-------------|--------|
| `csr_reflect_on_past` | Semantic search across past conversations | read-only |
| `store_reflection` | Store insights for future retrieval | **writes** |
| `csr_quick_check` | Fast existence check (count + top match) | read-only |
| `search_by_recency` | Time-constrained search ("last week") | read-only |
| `get_recent_work` | "What did we work on?" with session grouping | read-only |
| `get_timeline` | Activity timeline with statistics | read-only |
| `csr_search_by_file` | Find conversations that touched a file | read-only |
| `csr_search_by_concept` | Theme-based search ("security", "testing") | read-only |
| `csr_search_insights` | Aggregated patterns from search results | read-only |
| `csr_get_more` | Paginate through additional results | read-only |
| `get_full_conversation` | Retrieve complete JSONL conversation | read-only |
| `get_session_learnings` | Iteration-level memory for Ralph loops | read-only |
</details>
<details>
<summary><strong>Hooks</strong> — 6 session lifecycle hooks</summary>
| Hook | What it does |
|------|-------------|
| **SessionStart** | Surfaces relevant past context at conversation start |
| **UserPromptSubmit** | Predicts and injects context before Claude responds |
| **PostToolUse** | Tracks file edits with session-scoped dedup |
| **Stop** | Stores iteration learnings, detects stuck patterns |
| **PreCompact** | Backs up state before context compaction |
| **SessionEnd** | Stores session narrative for future retrieval |
All hooks use catch-all error handling. They never block Claude Code.
</details>
<details>
<summary><strong>AI Narratives</strong> — optional 9.3x quality boost</summary>
Transform raw conversations into rich, searchable narratives. Requires an Anthropic API key.
```bash
csr-engine daemon
```
| Metric | Without | With AI Narratives |
|--------|---------|-------------------|
| Search quality | 0.074 | 0.691 (9.3x) |
| Token compression | 100% | 18% (82% reduction) |
| Cost per conversation | - | ~$0.012 (Batch API) |
</details>
<details>
<summary><strong>CLI Reference</strong></summary>
```
csr-engine Start MCP server (default)
csr-engine setup One-shot setup: import + MCP + hooks
csr-engine status System status (JSON)
csr-engine status --compact One-line statusline output
csr-engine daemon Background enrichment daemon
csr-engine hook install --apply Install Claude Code hooks
csr-engine eval Quick eval (5 tests)
csr-engine eval --full Full eval (20 tests)
csr-engine quality <file> AST-based code quality analysis
```
</details>
<details>
<summary><strong>Upgrading from v7.x</strong></summary>
v8.0 replaces the Python/Docker stack with a single Rust binary.
```bash
docker compose down 2>/dev/null
curl -fsSL https://raw.githubusercontent.com/ramakay/claude-self-reflect/main/scripts/install.sh | sh
```
Your conversation data (`~/.claude/projects/`) is untouched. The new engine re-imports from the same JSONL files.
</details>
<details>
<summary><strong>Troubleshooting</strong></summary>
| Symptom | Fix |
|---------|-----|
| No search results | Run `csr-engine setup` |
| MCP tools not available | Run `csr-engine setup`, restart Claude Code |
| "spawn ENOENT" in MCP | Ensure `csr-engine` is in PATH |
| Slow first startup | Normal (~14s for index rebuild, subsequent: ~93ms) |
