# Chroma Vector Database - Hybrid Semantic Search
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Claude-Mem v5.0.0 introduced **Chroma**, a vector database that enables semantic search across your memory stream. Combined with SQLite's FTS5 keyword search, this creates a powerful **hybrid search architecture** that finds contextually relevant observations using both meaning and keywords.
|
||||||
|
|
||||||
|
**Key Benefits:**
|
||||||
|
- 🧠 **Semantic Search** - Find observations by meaning, not just keywords
|
||||||
|
- 🔍 **Hybrid Architecture** - Combines semantic similarity with keyword matching
|
||||||
|
- ⏱️ **Recency Filtering** - Focus on recent 90 days for relevant context
|
||||||
|
- ⚡ **Fast Performance** - Semantic search under 200ms with 8,000+ documents
|
||||||
|
- 🔄 **Auto-Sync** - ChromaSync service keeps vectors updated automatically
|
||||||
|
|
||||||
|
## What is Chroma?
|
||||||
|
|
||||||
|
[ChromaDB](https://www.trychroma.com/) is an open-source vector database designed for AI applications. It stores text as **vector embeddings** - mathematical representations that capture semantic meaning.
|
||||||
|
|
||||||
|
**Example:**
|
||||||
|
```
|
||||||
|
Query: "authentication bug"
|
||||||
|
Keyword Match: Must contain both "authentication" AND "bug"
|
||||||
|
Semantic Match: Also finds "login error", "auth failure", "sign-in issue"
|
||||||
|
```
|
||||||
|
|
||||||
|
Semantic search understands that "authentication bug" is conceptually similar to "login error" even though they share no keywords.
|
||||||
|
|
||||||
|

||||||
|
### ChromaSync Service
|
||||||
|
|
||||||
|
The **ChromaSync** service (`src/services/sync/ChromaSync.ts`) automatically synchronizes observations to Chroma:
|
||||||
|
|
||||||
|
**When Observations Are Synced:**
|
||||||
|
1. **Session Summary** - After each session completes, all new observations synced
|
||||||
|
2. **Worker Startup** - On initialization, checks for unsynced observations
|
||||||
|
3. **Manual Trigger** - Can force sync via internal API (development only)
|
||||||
|
|
||||||
|
**What Gets Embedded:**
|
||||||
|
- Observation ID (unique identifier)
|
||||||
|
- Title (compressed learning statement)
|
||||||
|
- Narrative (detailed explanation)
|
||||||
|
- Project path (for project-specific filtering)
|
||||||
|
- Timestamp (for recency filtering)
|
||||||
|
- Concepts (semantic tags)
|
||||||
|
- File references (associated code files)
|
||||||
|
|
||||||
|
**Embedding Model:**
|
||||||
|
- Currently using Chroma's default embedding function
|
||||||
|
- Future: Configurable embedding models (e.g., OpenAI, sentence-transformers)
|
||||||
|
|
||||||
|
### Data Structure
|
||||||
|
|
||||||
|
**SQLite (Source of Truth):**
|
||||||
|
```sql
|
||||||
|
CREATE TABLE observations (
|
||||||
|
id INTEGER PRIMARY KEY,
|
||||||
|
title TEXT,
|
||||||
|
narrative TEXT,
|
||||||
|
facts TEXT,
|
||||||
|
concepts TEXT,
|
||||||
|
files TEXT,
|
||||||
|
type TEXT,
|
||||||
|
projectPath TEXT,
|
||||||
|
createdAt INTEGER
|
||||||
|
);
|
||||||
|
```
|
||||||
|
|
||||||
|
**Chroma (Vector Embeddings):**
|
||||||
|
```typescript
|
||||||
|
{
|
||||||
|
ids: ["obs_12345"],
|
||||||
|
embeddings: [[0.123, -0.456, ...]], // 384-dimensional vector
|
||||||
|
documents: ["Title: Authentication flow\nNarrative: Implemented..."],
|
||||||
|
metadatas: [{
|
||||||
|
type: "feature",
|
||||||
|
project: "claude-mem",
|
||||||
|
timestamp: 1698765432000,
|
||||||
|
concepts: "pattern,architecture"
|
||||||
|
}]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## How Semantic Search Works
|
||||||
|
|
||||||
|
### Vector Embeddings
|
||||||
|
|
||||||
|
Text converted to high-dimensional vectors that capture meaning:
|
||||||
|
|
||||||
|
```
|
||||||
|
"user authentication" → [0.12, -0.34, 0.56, ..., 0.78]
|
||||||
|
"login system" → [0.15, -0.32, 0.54, ..., 0.81]
|
||||||
|
"database schema" → [-0.45, 0.67, -0.23, ..., 0.12]
|
||||||
|
```
|
||||||
|
|
||||||
|
Notice: "user authentication" and "login system" have similar vectors (close in vector space), while "database schema" is distant.
|
||||||
|
|
||||||
|
### Similarity Search
|
||||||
|
|
||||||
|
Chroma uses **cosine similarity** to find nearest neighbors:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Query embedding
|
||||||
|
query: "authentication bug"
|
||||||
|
query_vector: [0.14, -0.33, 0.55, ..., 0.79]
|
||||||
|
|
||||||
|
// Find observations with similar vectors
|
||||||
|
results = chroma.query(
|
||||||
|
query_vector,
|
||||||
|
n_results: 10,
|
||||||
|
where: { timestamp: { $gte: now - 90_days } }
|
||||||
|
)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Result Ranking:**
|
||||||
|
- Higher cosine similarity = more semantically similar
|
||||||
|
- Filtered by 90-day recency window
|
||||||
|
- Combined with keyword matches from FTS5
|
||||||
|
|
||||||
|
## 90-Day Recency Filtering
|
||||||
|
|
||||||
|
Why 90 days?
|
||||||
|
|
||||||
|
**Rationale:**
|
||||||
|
- Recent context more likely relevant to current work
|
||||||
|
- Prevents very old observations from diluting results
|
||||||
|
- Balances completeness with relevance
|
||||||
|
- Reduces vector search space for faster queries
|
||||||
|
|
||||||
|
**Implementation:**
|
||||||
|
```typescript
|
||||||
|
const ninetyDaysAgo = Date.now() - (90 * 24 * 60 * 60 * 1000);
|
||||||
|
|
||||||
|
// Chroma metadata filter
|
||||||
|
where: {
|
||||||
|
timestamp: { $gte: ninetyDaysAgo }
|
||||||
|
}
|
||||||
|
|
||||||
|
// SQLite WHERE clause
|
||||||
|
WHERE createdAt >= ?
|
||||||
|
```
|
||||||
|
|
||||||
|
**Configurable?**
|
||||||
|
- Not currently user-configurable
|
||||||
|
- Hard-coded in `src/servers/search-server.ts`
|
||||||
|
- Future: Add `CLAUDE_MEM_RECENCY_DAYS` environment variable
|
||||||
|
|
||||||
|
## MCP Tool Integration
|
||||||
|
|
||||||
|
All 9 MCP search tools benefit from hybrid search:
|
||||||
|
|
||||||
|
### search_observations (Hybrid)
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Keyword-only (v4.x)
|
||||||
|
search_observations(query: "authentication")
|
||||||
|
// Returns: Observations containing "authentication"
|
||||||
|
|
||||||
|
// Hybrid semantic + keyword (v5.x)
|
||||||
|
search_observations(query: "authentication")
|
||||||
|
// Returns: Observations with "authentication" PLUS semantically similar:
|
||||||
|
// - "login system"
|
||||||
|
// - "user credentials"
|
||||||
|
// - "session management"
|
||||||
|
```
|
||||||
|
|
||||||
|
### get_timeline_by_query (Semantic-First)
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Uses Chroma to find best match, then builds timeline
|
||||||
|
get_timeline_by_query(
|
||||||
|
query: "when did we implement the viewer UI?",
|
||||||
|
mode: "auto",
|
||||||
|
depth_before: 10,
|
||||||
|
depth_after: 10
|
||||||
|
)
|
||||||
|
|
||||||
|
// Chroma finds: Observation #4057 "Web-Based Viewer UI for Real-Time Memory Stream"
|
||||||
|
// Returns: Timeline with 10 observations before + anchor + 10 after
|
||||||
|
```
|
||||||
|
|
||||||
|
### Benefits Across All Tools
|
||||||
|
|
||||||
|
- **find_by_concept**: Semantic similarity finds related concepts
|
||||||
|
- **find_by_file**: Finds semantically similar code changes
|
||||||
|
- **find_by_type**: Better relevance ranking within type
|
||||||
|
- **get_recent_context**: Prioritizes semantically relevant recent context
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
### Benchmarks (8,279 vector documents)
|
||||||
|
|
||||||
|
| Operation | Time | Notes |
|
||||||
|
|-----------|------|-------|
|
||||||
|
| **Semantic Query** | 150-200ms | 90-day window, top 10 results |
|
||||||
|
| **Keyword Query (FTS5)** | 5-10ms | Full-text search |
|
||||||
|
| **Hybrid Query** | 160-220ms | Combined semantic + keyword |
|
||||||
|
| **Initial Sync** | 2-5 min | First-time embedding of all observations |
|
||||||
|
| **Incremental Sync** | 100-500ms | 1-10 new observations per session |
|
||||||
|
|
||||||
|
### Memory Usage
|
||||||
|
|
||||||
|
- **Chroma DB Size**: ~50MB for 8,000 observations
|
||||||
|
- **Embeddings**: 384 dimensions × 4 bytes = 1.5KB per observation
|
||||||
|
- **Metadata**: ~500 bytes per observation (project, type, timestamp)
|
||||||
|
- **Total**: ~2KB per observation in Chroma
|
||||||
|
|
||||||
|
### Optimization Tips
|
||||||
|
|
||||||
|
1. **Reduce vector dimensions**: Use smaller embedding models (future)
|
||||||
|
2. **Adjust recency window**: Narrow to 30/60 days for faster queries
|
||||||
|
3. **Limit result count**: Request fewer results (n_results=5 vs 10)
|
||||||
|
4. **Project filtering**: Add project filter to metadata query
|
||||||
|
|
||||||
|
## Installation & Dependencies
|
||||||
|
|
||||||
|
### Python Requirement
|
||||||
|
|
||||||
|
Chroma requires Python 3.7+ installed:
|
||||||
|
|
||||||
|
**Check Python:**
|
||||||
|
```bash
|
||||||
|
python3 --version
|
||||||
|
# Should show: Python 3.7.x or higher
|
||||||
|
```
|
||||||
|
|
||||||
|
**Install Python (if needed):**
|
||||||
|
- **macOS**: `brew install python3`
|
||||||
|
- **Windows**: Download from [python.org](https://www.python.org/downloads/)
|
||||||
|
- **Linux**: `apt-get install python3` or `yum install python3`
|
||||||
|
|
||||||
|
### ChromaDB Installation
|
||||||
|
|
||||||
|
Chroma installed automatically as npm dependency:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
npm install
|
||||||
|
# Installs: chromadb (Python package via node-gyp bindings)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Manual Installation (if auto-install fails):**
|
||||||
|
```bash
|
||||||
|
pip3 install chromadb
|
||||||
|
```
|
||||||
|
|
||||||
|
### Troubleshooting Installation
|
||||||
|
|
||||||
|
**Error: "Python not found"**
|
||||||
|
```bash
|
||||||
|
# Set Python path explicitly
|
||||||
|
export PYTHON=/usr/local/bin/python3
|
||||||
|
npm install
|
||||||
|
```
|
||||||
|
|
||||||
|
**Error: "chromadb module not found"**
|
||||||
|
```bash
|
||||||
|
# Reinstall chromadb
|
||||||
|
pip3 install --upgrade chromadb
|
||||||
|
|
||||||
|
# Verify installation
|
||||||
|
python3 -c "import chromadb; print(chromadb.__version__)"
|
||||||
|
```
|
||||||
|
|
||||||
|
**Error: "node-gyp build failed"**
|
||||||
|
```bash
|
||||||
|
# Install build tools
|
||||||
|
# macOS: xcode-select --install
|
||||||
|
# Windows: npm install --global windows-build-tools
|
||||||
|
# Linux: apt-get install build-essential
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
### Environment Variables
|
||||||
|
|
||||||
|
Currently no user-configurable settings. Future options:
|
||||||
|
|
||||||
|
```json
|
||||||
|
// Proposed for future versions
|
||||||
|
{
|
||||||
|
"env": {
|
||||||
|
"CLAUDE_MEM_CHROMA_ENABLED": "true", // Enable/disable Chroma
|
||||||
|
"CLAUDE_MEM_CHROMA_PATH": "~/.claude-mem/chroma", // DB location
|
||||||
|
"CLAUDE_MEM_EMBEDDING_MODEL": "default", // Embedding model choice
|
||||||
|
"CLAUDE_MEM_RECENCY_DAYS": "90", // Recency window
|
||||||
|
"CLAUDE_MEM_VECTOR_DIM": "384" // Embedding dimensions
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Disabling Chroma (Future)
|
||||||
|
|
||||||
|
To disable semantic search and use keyword-only:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"env": {
|
||||||
|
"CLAUDE_MEM_CHROMA_ENABLED": "false"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
Falls back to SQLite FTS5 keyword search only.
|
||||||
|
|
||||||
|
## Database Maintenance
|
||||||
|
|
||||||
|
### Location
|
||||||
|
|
||||||
|
```
|
||||||
|
~/.claude-mem/chroma/
|
||||||
|
├── chroma.sqlite3 # Chroma metadata database
|
||||||
|
└── index/ # Vector index files
|
||||||
|
└── *.bin # Binary vector data
|
||||||
|
```
|
||||||
|
|
||||||
|
### Backup
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Backup entire Chroma directory
|
||||||
|
cp -r ~/.claude-mem/chroma ~/.claude-mem/chroma.backup
|
||||||
|
|
||||||
|
# Restore from backup
|
||||||
|
rm -rf ~/.claude-mem/chroma
|
||||||
|
cp -r ~/.claude-mem/chroma.backup ~/.claude-mem/chroma
|
||||||
|
```
|
||||||
|
|
||||||
|
### Reset Chroma (Force Resync)
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Delete Chroma database
|
||||||
|
rm -rf ~/.claude-mem/chroma
|
||||||
|
|
||||||
|
# Restart worker to trigger full resync
|
||||||
|
npm run worker:restart
|
||||||
|
|
||||||
|
# Check logs for sync progress
|
||||||
|
npm run worker:logs
|
||||||
|
```
|
||||||
|
|
||||||
|
**Note**: Resync can take 2-5 minutes for thousands of observations.
|
||||||
|
|
||||||
|
### Disk Space Management
|
||||||
|
|
||||||
|
**Chroma grows with observations:**
|
||||||
|
- 1,000 observations ≈ 5MB
|
||||||
|
- 10,000 observations ≈ 50MB
|
||||||
|
- 100,000 observations ≈ 500MB
|
||||||
|
|
||||||
|
**Cleanup old observations:**
|
||||||
|
```sql
|
||||||
|
-- Delete observations older than 1 year
|
||||||
|
-- This will trigger Chroma resync on next startup
|
||||||
|
sqlite3 ~/.claude-mem/claude-mem.db \
|
||||||
|
"DELETE FROM observations WHERE createdAt < strftime('%s', 'now', '-1 year') * 1000;"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Advanced Usage
|
||||||
|
|
||||||
|
### Direct Chroma Queries (Development)
|
||||||
|
|
||||||
|
For debugging or custom queries:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
import { ChromaSync } from './services/sync/ChromaSync';
|
||||||
|
|
||||||
|
const sync = new ChromaSync();
|
||||||
|
await sync.initialize();
|
||||||
|
|
||||||
|
// Query Chroma directly
|
||||||
|
const results = await sync.query({
|
||||||
|
queryTexts: ["authentication implementation"],
|
||||||
|
nResults: 10,
|
||||||
|
where: {
|
||||||
|
type: "feature",
|
||||||
|
timestamp: { $gte: Date.now() - 90_days }
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
console.log(results.ids, results.distances, results.documents);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Custom Embedding Models (Future)
|
||||||
|
|
||||||
|
Chroma supports multiple embedding models:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Future configuration
|
||||||
|
const sync = new ChromaSync({
|
||||||
|
embeddingModel: "sentence-transformers/all-MiniLM-L6-v2", // Smaller, faster
|
||||||
|
// or: "text-embedding-ada-002" (OpenAI, requires API key)
|
||||||
|
// or: "all-mpnet-base-v2" (Higher quality, slower)
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Metadata Filtering
|
||||||
|
|
||||||
|
Chroma supports advanced metadata queries:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Find observations by type and project
|
||||||
|
results = await sync.query({
|
||||||
|
queryTexts: ["API design"],
|
||||||
|
where: {
|
||||||
|
$and: [
|
||||||
|
{ type: { $in: ["decision", "feature"] } },
|
||||||
|
{ project: "claude-mem" }
|
||||||
|
]
|
||||||
|
}
|
||||||
|
});
|
||||||
|
|
||||||
|
// Find recent observations
|
||||||
|
results = await sync.query({
|
||||||
|
queryTexts: ["database schema"],
|
||||||
|
where: {
|
||||||
|
timestamp: { $gte: Date.now() - 30_days }
|
||||||
|
}
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
## Comparison: Semantic vs Keyword Search
|
||||||
|
|
||||||
|
| Aspect | Semantic (Chroma) | Keyword (FTS5) |
|
||||||
|
|--------|-------------------|----------------|
|
||||||
|
| **Speed** | 150-200ms | 5-10ms |
|
||||||
|
| **Accuracy** | High (meaning-based) | Medium (exact match) |
|
||||||
|
| **Storage** | ~2KB per observation | ~500 bytes per observation |
|
||||||
|
| **Conceptual Matching** | ✅ Yes | ❌ No |
|
||||||
|
| **Exact Match** | ❌ Not guaranteed | ✅ Always |
|
||||||
|
| **Typo Tolerance** | ✅ High | ⚠️ Limited (fuzzy) |
|
||||||
|
| **Dependencies** | Python + chromadb | None (SQLite built-in) |
|
||||||
|
| **Recency Bias** | ✅ Built-in (90 days) | Manual filtering |
|
||||||
|
|
||||||
|
**Best Practice:** Use hybrid search (both) for optimal results.
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### "Chroma not found" Error
|
||||||
|
|
||||||
|
**Symptom:** Worker logs show "Chroma not available, using keyword-only search"
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
```bash
|
||||||
|
# Check Python installation
|
||||||
|
python3 --version
|
||||||
|
|
||||||
|
# Reinstall chromadb
|
||||||
|
pip3 install chromadb
|
||||||
|
|
||||||
|
# Restart worker
|
||||||
|
npm run worker:restart
|
||||||
|
```
|
||||||
|
|
||||||
|
### Slow Query Performance
|
||||||
|
|
||||||
|
**Symptom:** Searches taking >1 second
|
||||||
|
|
||||||
|
**Solutions:**
|
||||||
|
1. Reduce recency window (edit `src/servers/search-server.ts`)
|
||||||
|
2. Limit result count (`nResults: 5` instead of 10)
|
||||||
|
3. Add project filter to narrow search space
|
||||||
|
4. Check Chroma index size (may need rebuild)
|
||||||
|
|
||||||
|
### Out of Memory Errors
|
||||||
|
|
||||||
|
**Symptom:** Worker crashes with "JavaScript heap out of memory"
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
```bash
|
||||||
|
# Increase Node.js heap size
|
||||||
|
export NODE_OPTIONS="--max-old-space-size=4096"
|
||||||
|
|
||||||
|
# Restart worker
|
||||||
|
npm run worker:restart
|
||||||
|
```
|
||||||
|
|
||||||
|
### Sync Taking Too Long
|
||||||
|
|
||||||
|
**Symptom:** Initial Chroma sync takes >10 minutes
|
||||||
|
|
||||||
|
**Possible Causes:**
|
||||||
|
- Large number of observations (>10,000)
|
||||||
|
- Slow embedding model
|
||||||
|
- Limited CPU resources
|
||||||
|
|
||||||
|
**Solutions:**
|
||||||
|
1. Let it complete (one-time cost)
|
||||||
|
2. Delete very old observations to reduce count
|
||||||
|
3. Close resource-intensive apps during sync
|
||||||
|
|
||||||
|
## Future Enhancements
|
||||||
|
|
||||||
|
Potential improvements for future versions:
|
||||||
|
|
||||||
|
- **Configurable Recency**: User-defined recency window (30/60/90/365 days)
|
||||||
|
- **Custom Embeddings**: Choose embedding model (quality vs speed trade-off)
|
||||||
|
- **Incremental Updates**: Update existing vectors instead of full resync
|
||||||
|
- **Semantic Filters**: Search by semantic concept ("all architectural decisions")
|
||||||
|
- **Multi-Language Support**: Embeddings optimized for non-English code/docs
|
||||||
|
- **Clustering**: Auto-cluster related observations for discovery
|
||||||
|
- **Visualization**: 2D/3D visualization of vector space (similar observations near each other)
|
||||||
|
|
||||||

## Features In Detail
|
||||||
|
|
||||||
|
### Real-Time Updates (SSE)
|
||||||
|
|
||||||
|
The viewer uses Server-Sent Events to receive updates instantly:
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// SSE message format
|
||||||
|
{
|
||||||
|
"type": "observation" | "summary" | "prompt" | "projects" | "processing",
|
||||||
|
"data": { /* record data */ }
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Event Types:**
|
||||||
|
- `observation` - New observation created
|
||||||
|
- `summary` - Session summary generated
|
||||||
|
- `prompt` - User prompt captured
|
||||||
|
- `projects` - Project list updated
|
||||||
|
- `processing` - Session processing status changed
|
||||||
|
|
||||||
|
**Connection Management:**
|
||||||
|
- Auto-reconnect on disconnect with exponential backoff
|
||||||
|
- Visual connection status indicator in header
|
||||||
|
- Graceful degradation if SSE unavailable
|
||||||
|
|
||||||
|
### Infinite Scroll Pagination
|
||||||
|
|
||||||
|
The feed loads historical data progressively:
|
||||||
|
|
||||||
|
1. **Initial Load**: First 20 records loaded on mount
|
||||||
|
2. **Scroll Trigger**: When user scrolls to 80% of feed height
|
||||||
|
3. **Batch Load**: Next 20 records fetched via `/api/{type}?offset=X&limit=20`
|
||||||
|
4. **Deduplication**: Merges with real-time data, removes duplicates by ID
|
||||||
|
5. **Loading State**: Skeleton cards show while fetching
|
||||||
|
|
||||||
|
**Performance:**
|
||||||
|
- Requests debounced to prevent spam
|
||||||
|
- Only visible when scrolled near bottom
|
||||||
|
- Continues until no more records available
|
||||||
|
|
||||||
|
### Project Filtering
|
||||||
|
|
||||||
|
Filter memory stream by specific projects:
|
||||||
|
|
||||||
|
1. Projects extracted from observations, summaries, and prompts
|
||||||
|
2. Sidebar shows all unique project names with counts
|
||||||
|
3. Click project name to filter feed
|
||||||
|
4. Click "All Projects" to clear filter
|
||||||
|
5. Filter persisted to localStorage
|
||||||
|
|
||||||
|
**Project Detection:**
|
||||||
|
- Extracted from `projectPath` or `project` field in records
|
||||||
|
- Basename of path used as project name
|
||||||
|
- Empty/null projects shown as "(No Project)"
|
||||||
|
|
||||||
|
### Theme Toggle (v5.1.2)
|
||||||
|
|
||||||
|
Three theme modes available:
|
||||||
|
|
||||||
|
- **Light Mode**: Clean white background, dark text
|
||||||
|
- **Dark Mode**: Dark background, light text (default)
|
||||||
|
- **System**: Matches OS preference automatically
|
||||||
|
|
||||||
|
**Implementation:**
|
||||||
|
```typescript
|
||||||
|
// Theme preference stored in localStorage
|
||||||
|
localStorage.setItem('theme-preference', 'light' | 'dark' | 'system');
|
||||||
|
|
||||||
|
// CSS variables updated dynamically
|
||||||
|
document.documentElement.setAttribute('data-theme', resolvedTheme);
|
||||||
|
```
|
||||||
|
|
||||||
|
**CSS Variables:**
|
||||||
|
```css
|
||||||
|
:root[data-theme="light"] {
|
||||||
|
--bg-primary: #ffffff;
|
||||||
|
--text-primary: #1f2937;
|
||||||
|
/* ... */
|
||||||
|
}
|
||||||
|
|
||||||
|
:root[data-theme="dark"] {
|
||||||
|
--bg-primary: #111827;
|
||||||
|
--text-primary: #f9fafb;
|
||||||
|
/* ... */
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Settings Persistence
|
||||||
|
|
||||||
|
Settings automatically saved to worker service:
|
||||||
|
|
||||||
|
**Saved Settings:**
|
||||||
|
- `sidebarOpen` - Sidebar expanded/collapsed state
|
||||||
|
- `selectedProject` - Current project filter
|
||||||
|
- `theme` - Theme preference (light/dark/system)
|
||||||
|
|
||||||
|
**API Endpoints:**
|
||||||
|
- `GET /api/settings` - Retrieve saved settings
|
||||||
|
- `POST /api/settings` - Save settings (debounced 500ms)
|
||||||
|
|
||||||
|
**Local Fallback:**
|
||||||
|
- If API unavailable, settings stored in localStorage
|
||||||
|
- Synced back to API when connection restored
|
||||||
|
|
||||||
|
## Usage Guide
|
||||||
|
|
||||||
|
### Opening the Viewer
|
||||||
|
|
||||||
|
1. Ensure claude-mem worker is running (auto-starts with Claude Code)
|
||||||
|
2. Open browser to http://localhost:37777
|
||||||
|
3. Viewer loads automatically with recent records
|
||||||
|
|
||||||
|
### Navigating the Feed
|
||||||
|
|
||||||
|
**Cards Displayed:**
|
||||||
|
- **Observation Cards** (blue accent) - Tool usage observations with title, narrative, concepts, files
|
||||||
|
- **Summary Cards** (green accent) - Session summaries with request, completion, learnings
|
||||||
|
- **Prompt Cards** (purple accent) - Raw user prompts with timestamp and project
|
||||||
|
|
||||||
|
**Card Features:**
|
||||||
|
- Click to expand/collapse full details
|
||||||
|
- Type indicators (🔴 bugfix, 🟣 feature, 🔄 refactor, etc.)
|
||||||
|
- Concept tags (clickable for future filtering)
|
||||||
|
- File references with paths
|
||||||
|
- Timestamps in relative format ("2 hours ago")
|
||||||
|
|
||||||
|
### Using Project Filters
|
||||||
|
|
||||||
|
1. **Open Sidebar**: Click hamburger menu (☰) in top-left
|
||||||
|
2. **View Stats**: See total observations, sessions, prompts
|
||||||
|
3. **Select Project**: Click project name to filter
|
||||||
|
4. **View Counts**: Numbers show records per project
|
||||||
|
5. **Clear Filter**: Click "All Projects" to reset
|
||||||
|
|
||||||
|
### Changing Theme
|
||||||
|
|
||||||
|
1. **Open Theme Toggle**: Click theme icon in header
|
||||||
|
2. **Select Mode**:
|
||||||
|
- ☀️ Light mode
|
||||||
|
- 🌙 Dark mode
|
||||||
|
- 💻 System (follows OS)
|
||||||
|
3. **Auto-Save**: Preference saved immediately
|
||||||
|
4. **Smooth Transition**: CSS transitions between themes
|
||||||
|
|
||||||
|
### Troubleshooting
|
||||||
|
|
||||||
|
**Viewer Not Loading:**
|
||||||
|
```bash
|
||||||
|
# Check worker status
|
||||||
|
npm run worker:logs
|
||||||
|
|
||||||
|
# Restart worker
|
||||||
|
npm run worker:restart
|
||||||
|
|
||||||
|
# Check if port 37777 is available
|
||||||
|
lsof -i :37777
|
||||||
|
```
|
||||||
|
|
||||||
|
**SSE Connection Issues:**
|
||||||
|
- Check browser console for connection errors
|
||||||
|
- Verify no proxy/firewall blocking EventSource
|
||||||
|
- Auto-reconnect attempts every 1-5s with exponential backoff
|
||||||
|
|
||||||
|
**Theme Not Persisting:**
|
||||||
|
- Check localStorage: `localStorage.getItem('theme-preference')`
|
||||||
|
- Verify `/api/settings` endpoint responding
|
||||||
|
- Clear browser cache if stale
|
||||||
|
|
||||||
|
**Infinite Scroll Not Triggering:**
|
||||||
|
- Scroll to 80% of feed height
|
||||||
|
- Check browser console for fetch errors
|
||||||
|
- Verify `/api/{type}` endpoints responding with data
|
||||||
|
|
||||||
|
## Development
|
||||||
|
|
||||||
|
### Building the Viewer
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Build viewer UI
|
||||||
|
npm run build
|
||||||
|
|
||||||
|
# Output: plugin/ui/viewer.html (self-contained)
|
||||||
|
```
|
||||||
|
|
||||||
|
### Adding New Features
|
||||||
|
|
||||||
|
**Example: Add a new card component**
|
||||||
|
|
||||||
|
1. Create component:
|
||||||
|
```typescript
|
||||||
|
// src/ui/viewer/components/cards/MyCard.tsx
|
||||||
|
export function MyCard({ data }: { data: MyData }) {
|
||||||
|
return (
|
||||||
|
<div className="card">
|
||||||
|
<div className="card-header">{data.title}</div>
|
||||||
|
<div className="card-body">{data.content}</div>
|
||||||
|
</div>
|
||||||
|
);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Add to Feed component:
|
||||||
|
```typescript
|
||||||
|
// src/ui/viewer/components/Feed.tsx
|
||||||
|
import { MyCard } from './cards/MyCard';
|
||||||
|
|
||||||
|
// In render:
|
||||||
|
{myData.map(item => <MyCard key={item.id} data={item} />)}
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Rebuild:
|
||||||
|
```bash
|
||||||
|
npm run build
|
||||||
|
npm run sync-marketplace
|
||||||
|
npm run worker:restart
|
||||||
|
```
|
||||||
|
|
||||||
|
### Testing Changes
|
||||||
|
|
||||||
|
1. Make changes to `src/ui/viewer/`
|
||||||
|
2. Rebuild: `npm run build`
|
||||||
|
3. Restart worker: `npm run worker:restart`
|
||||||
|
4. Refresh browser (http://localhost:37777)
|
||||||
|
5. Check browser console for errors
|
||||||
|
|
||||||
|
## API Integration
|
||||||
|
|
||||||
|
The viewer consumes these worker service endpoints:
|
||||||
|
|
||||||
|
### Data Retrieval
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Get paginated observations
|
||||||
|
GET /api/observations?offset=0&limit=20&project=myproject
|
||||||
|
Response: { observations: Observation[], hasMore: boolean }
|
||||||
|
|
||||||
|
// Get paginated summaries
|
||||||
|
GET /api/summaries?offset=0&limit=20&project=myproject
|
||||||
|
Response: { summaries: Summary[], hasMore: boolean }
|
||||||
|
|
||||||
|
// Get paginated prompts
|
||||||
|
GET /api/prompts?offset=0&limit=20&project=myproject
|
||||||
|
Response: { prompts: UserPrompt[], hasMore: boolean }
|
||||||
|
|
||||||
|
// Get database stats
|
||||||
|
GET /api/stats
|
||||||
|
Response: { totalObservations: number, totalSessions: number, ... }
|
||||||
|
```
|
||||||
|
|
||||||
|
### Real-Time Stream
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Server-Sent Events stream
|
||||||
|
GET /stream
|
||||||
|
|
||||||
|
// Message format:
|
||||||
|
event: observation
|
||||||
|
data: {"type":"observation","data":{...}}
|
||||||
|
|
||||||
|
event: summary
|
||||||
|
data: {"type":"summary","data":{...}}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Settings
|
||||||
|
|
||||||
|
```typescript
|
||||||
|
// Get settings
|
||||||
|
GET /api/settings
|
||||||
|
Response: { sidebarOpen: boolean, selectedProject: string, ... }
|
||||||
|
|
||||||
|
// Save settings
|
||||||
|
POST /api/settings
|
||||||
|
Body: { sidebarOpen: boolean, selectedProject: string, ... }
|
||||||
|
Response: { success: boolean }
|
||||||
|
```
|
||||||
|
|
||||||
|
## Performance Considerations
|
||||||
|
|
||||||
|
### Bundle Size
|
||||||
|
- Self-contained HTML: ~150KB (gzipped)
|
||||||
|
- No external dependencies loaded at runtime
|
||||||
|
- Monaspace Radon font embedded (subset)
|
||||||
|
|
||||||
|
### Memory Management
|
||||||
|
- Virtualization: Only renders visible cards
|
||||||
|
- Deduplication: Prevents duplicate records in memory
|
||||||
|
- Cleanup: Old records beyond pagination limit pruned
|
||||||
|
|
||||||
|
### Network Efficiency
|
||||||
|
- SSE: Single long-lived connection for real-time updates
|
||||||
|
- REST: Paginated requests (20 records per batch)
|
||||||
|
- Debouncing: Settings saves debounced 500ms
|
||||||
|
|
||||||
|
### Rendering Performance
|
||||||
|
- React.memo: Cards memoized to prevent unnecessary re-renders
|
||||||
|
- useMemo: Data merging/filtering memoized
|
||||||
|
- CSS transitions: GPU-accelerated for smooth animations
|
||||||
|
|
||||||
|
## Future Enhancements
|
||||||
|
|
||||||
|
Potential features for future versions:
|
||||||
|
|
||||||
|
- **Search**: Full-text search across observations, summaries, prompts
|
||||||
|
- **Export**: Download data as JSON, CSV, or markdown
|
||||||
|
- **Charts**: Visualize observation frequency, types, concepts over time
|
||||||
|
- **Keyboard Shortcuts**: Navigate feed, toggle sidebar, switch themes
|
||||||
|
- **Notifications**: Browser notifications for important observations
|
||||||
|
- **Dark/Light Auto-Schedule**: Auto-switch theme based on time of day
|
||||||
|
- **Custom Themes**: User-defined color schemes
|
||||||
|
- **Multi-Project Views**: Compare multiple projects side-by-side
|
||||||

## v5.x: Maturity and User Experience
|
||||||
|
|
||||||
|
After establishing the solid v4 architecture, v5.x focused on user experience, visualization, and polish.
|
||||||
|
|
||||||
|
### v5.1.2: Theme Toggle (November 2025)
|
||||||
|
|
||||||
|
**What Changed**: Added light/dark mode theme toggle to viewer UI
|
||||||
|
|
||||||
|
**New Features**:
|
||||||
|
- User-selectable theme preference (light, dark, system)
|
||||||
|
- Persistent theme settings in localStorage
|
||||||
|
- Smooth theme transitions
|
||||||
|
- System preference detection
|
||||||
|
|
||||||
|
**Implementation**:
|
||||||
|
```typescript
|
||||||
|
// Theme context with persistence
|
||||||
|
const ThemeProvider = ({ children }) => {
|
||||||
|
const [theme, setTheme] = useState<'light' | 'dark' | 'system'>(() => {
|
||||||
|
return localStorage.getItem('claude-mem-theme') || 'system';
|
||||||
|
});
|
||||||
|
|
||||||
|
useEffect(() => {
|
||||||
|
localStorage.setItem('claude-mem-theme', theme);
|
||||||
|
}, [theme]);
|
||||||
|
|
||||||
|
return (
|
||||||
|
<ThemeContext.Provider value={{ theme, setTheme }}>
|
||||||
|
{children}
|
||||||
|
</ThemeContext.Provider>
|
||||||
|
);
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why It Matters**: Users working in different lighting conditions can now customize the viewer for comfort.
|
||||||
|
|
||||||
|
### v5.1.1: PM2 Windows Fix (November 2025)
|
||||||
|
|
||||||
|
**The Problem**: PM2 startup failed on Windows with ENOENT error
|
||||||
|
|
||||||
|
**Root Cause**:
|
||||||
|
```typescript
|
||||||
|
// ❌ Failed on Windows - PM2 not in PATH
|
||||||
|
execSync('pm2 start ecosystem.config.cjs');
|
||||||
|
```
|
||||||
|
|
||||||
|
**The Fix**:
|
||||||
|
```typescript
|
||||||
|
// ✅ Use full path to PM2 binary
|
||||||
|
const PM2_PATH = join(PLUGIN_ROOT, 'node_modules', '.bin', 'pm2');
|
||||||
|
execSync(`"${PM2_PATH}" start "${ECOSYSTEM_CONFIG}"`);
|
||||||
|
```
|
||||||
|
|
||||||
|
**Impact**: Cross-platform compatibility restored, Windows users can now use claude-mem without issues.
|
||||||
|
|
||||||
|
### v5.1.0: Web-Based Viewer UI (October 2025)
|
||||||
|
|
||||||
|
**The Breakthrough**: Real-time visualization of memory stream
|
||||||
|
|
||||||
|
**What We Built**:
|
||||||
|
- React-based web UI at http://localhost:37777
|
||||||
|
- Server-Sent Events (SSE) for real-time updates
|
||||||
|
- Infinite scroll pagination
|
||||||
|
- Project filtering
|
||||||
|
- Settings persistence (sidebar state, selected project)
|
||||||
|
- Auto-reconnection with exponential backoff
|
||||||
|
- GPU-accelerated animations
|
||||||
|
|
||||||
|
**New Worker Endpoints** (8 additions):
|
||||||
|
```
|
||||||
|
GET / # Serves viewer HTML
|
||||||
|
GET /stream # SSE real-time updates
|
||||||
|
GET /api/prompts # Paginated user prompts
|
||||||
|
GET /api/observations # Paginated observations
|
||||||
|
GET /api/summaries # Paginated session summaries
|
||||||
|
GET /api/stats # Database statistics
|
||||||
|
GET /api/settings # User settings
|
||||||
|
POST /api/settings # Save settings
|
||||||
|
```
|
||||||
|
|
||||||
|
**Database Enhancements**:
|
||||||
|
```typescript
|
||||||
|
// New SessionStore methods for viewer
|
||||||
|
getRecentPrompts(limit, offset, project?)
|
||||||
|
getRecentObservations(limit, offset, project?)
|
||||||
|
getRecentSummaries(limit, offset, project?)
|
||||||
|
getStats()
|
||||||
|
getUniqueProjects()
|
||||||
|
```
|
||||||
|
|
||||||
|
**React Architecture**:
|
||||||
|
```
|
||||||
|

|
```
|
||||||
|
|
||||||
|
**Build Process**:
|
||||||
|
```typescript
|
||||||
|
// esbuild bundles everything into single HTML file
|
||||||
|
esbuild.build({
|
||||||
|
entryPoints: ['src/ui/viewer/index.tsx'],
|
||||||
|
bundle: true,
|
||||||
|
outfile: 'plugin/ui/viewer.html',
|
||||||
|
loader: { '.tsx': 'tsx', '.woff2': 'dataurl' },
|
||||||
|
define: { 'process.env.NODE_ENV': '"production"' },
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why It Matters**: Users can now see exactly what's being captured in real-time, making the memory system transparent and debuggable.
|
||||||
|
|
||||||
|
### v5.0.3: Smart Install Caching (October 2025)
|
||||||
|
|
||||||
|
**The Problem**: `npm install` ran on every SessionStart (2-5 seconds)
|
||||||
|
|
||||||
|
**The Insight**: Dependencies rarely change between sessions
|
||||||
|
|
||||||
|
**The Solution**: Version-based caching
|
||||||
|
```typescript
|
||||||
|
// Check version marker before installing
|
||||||
|
const currentVersion = getPackageVersion();
|
||||||
|
const installedVersion = readFileSync('.install-version', 'utf-8');
|
||||||
|
|
||||||
|
if (currentVersion !== installedVersion) {
|
||||||
|
// Only install if version changed
|
||||||
|
await runNpmInstall();
|
||||||
|
writeFileSync('.install-version', currentVersion);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Cached Check Logic**:
|
||||||
|
1. Does `node_modules` exist?
|
||||||
|
2. Does `.install-version` match `package.json` version?
|
||||||
|
3. Is `better-sqlite3` present?
|
||||||
|
|
||||||
|
**Impact**:
|
||||||
|
- SessionStart hook: 2-5 seconds → 10ms (99.5% faster)
|
||||||
|
- Only installs on: first run, version change, missing deps
|
||||||
|
- Better Windows error messages with build tool help
|
||||||
|
|
||||||
|
### v5.0.2: Worker Health Checks (October 2025)
|
||||||
|
|
||||||
|
**What Changed**: More robust worker startup and monitoring
|
||||||
|
|
||||||
|
**New Features**:
|
||||||
|
```typescript
|
||||||
|
// Health check endpoint
|
||||||
|
app.get('/health', (req, res) => {
|
||||||
|
res.json({
|
||||||
|
status: 'ok',
|
||||||
|
uptime: process.uptime(),
|
||||||
|
port: WORKER_PORT,
|
||||||
|
memory: process.memoryUsage(),
|
||||||
|
});
|
||||||
|
});
|
||||||
|
|
||||||
|
// Smart worker startup
|
||||||
|
async function ensureWorkerHealthy() {
|
||||||
|
const healthy = await isWorkerHealthy(1000);
|
||||||
|
if (!healthy) {
|
||||||
|
await startWorker();
|
||||||
|
await waitForWorkerHealth(10000);
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Benefits**:
|
||||||
|
- Graceful degradation when worker is down
|
||||||
|
- Auto-recovery from crashes
|
||||||
|
- Better error messages for debugging
|
||||||
|
|
||||||
|

### v5.0.0: Hybrid Search Architecture (October 2025)
|
||||||
|
|
||||||
|
**The Evolution**: SQLite FTS5 + Chroma vector search
|
||||||
|
|
||||||
|
**What We Added**:
|
||||||
|
```
|
||||||
|
┌─────────────────────────────────────────────────────────┐
|
||||||
|
│ HYBRID SEARCH │
|
||||||
|
│ │
|
||||||
|
│ Text Query → SQLite FTS5 (keyword matching) │
|
||||||
|
│ ↓ │
|
||||||
|
│ Chroma Vector Search (semantic) │
|
||||||
|
│ ↓ │
|
||||||
|
│ Merge + Re-rank Results │
|
||||||
|
└─────────────────────────────────────────────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
**New Dependencies**:
|
||||||
|
- `chromadb` - Vector database for semantic search
|
||||||
|
- Python 3.8+ - Required by chromadb
|
||||||
|
|
||||||
|
**MCP Tools Enhancement**:
|
||||||
|
```typescript
|
||||||
|
// Chroma-backed semantic search
|
||||||
|
search_observations({
|
||||||
|
query: "authentication bug",
|
||||||
|
useSemanticSearch: true // Uses Chroma
|
||||||
|
});
|
||||||
|
|
||||||
|
// Falls back to FTS5 if Chroma unavailable
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why Hybrid**:
|
||||||
|
- FTS5: Fast keyword matching, no dependencies
|
||||||
|
- Chroma: Semantic understanding, finds related concepts
|
||||||
|
- Graceful degradation: Works without Chroma (FTS5 only)
|
||||||
|
|
||||||
|
**Trade-offs**:
|
||||||
|
- Added Python dependency (optional)
|
||||||
|
- Increased installation complexity
|
||||||
|
- Better search relevance

## 1. SessionStart Hook - Smart Install (`smart-install.js`)
|
||||||
|
|
||||||
|
**Purpose**: Intelligently manage dependencies and ensure worker service is running.
|
||||||
|
|
||||||
|
**Behavior**:
|
||||||
|
- Checks if dependencies need installation using version marker (`.install-version`)
|
||||||
|
- Only runs npm install when:
|
||||||
|
- First-time installation (no node_modules)
|
||||||
|
- Version changed in package.json
|
||||||
|
- Critical dependency missing (e.g., better-sqlite3)
|
||||||
|
- Provides Windows-specific error messages for build tool issues
|
||||||
|
- Auto-starts PM2 worker service after installation
|
||||||
|
- Fast when already installed (~10ms vs 2-5 seconds)
|
||||||
|
|
||||||
|
**Input** (via stdin):

|
```json
|
||||||

|
|
||||||
|
**Implementation**: `scripts/smart-install.js`
|
||||||
|

||||||
|
**Key Features**:
|
||||||
|
- Version caching prevents redundant installs
|
||||||
|
- Cross-platform compatible (Windows, macOS, Linux)
|
||||||
|
- Helpful error messages with troubleshooting steps
|
||||||
|
- Non-blocking worker startup
|
||||||
|
|
||||||
|
**v5.0.3 Enhancement**: Smart caching eliminates 2-5 second npm install on every SessionStart, reducing to ~10ms for already-installed dependencies.
|
||||||
|
|
||||||

|
### 8. get_context_timeline
|
||||||
|
|
||||||
|
Get a unified timeline of context (observations, sessions, and prompts) around a specific point in time. All record types are interleaved chronologically.
|
||||||
|
|
||||||
|
**Parameters**:
|
||||||
|
- `anchor` (required): Anchor point - observation ID, session ID (e.g., "S123"), or ISO timestamp
|
||||||
|
- `depth_before` (default: 10): Number of records to retrieve before anchor (max: 50)
|
||||||
|
- `depth_after` (default: 10): Number of records to retrieve after anchor (max: 50)
|
||||||
|
- `project`: Filter by project name
|
||||||
|
|
||||||
|
**Return Format**:
|
||||||
|
Returns `depth_before` records + anchor + `depth_after` records, all interleaved chronologically. Total records: `depth_before + 1 + depth_after`.
|
||||||
|
|
||||||
|
**Use Case**: Understanding "what was happening when X occurred"
|
||||||
|
|
||||||
|
**Example**:
|
||||||
|
```
|
||||||
|
# Timeline around observation #123
|
||||||
|
get_context_timeline with anchor=123 and depth_before=5 and depth_after=5
|
||||||
|
|
||||||
|
# Timeline around a session
|
||||||
|
get_context_timeline with anchor="S456" and depth_before=10 and depth_after=10
|
||||||
|
|
||||||
|
# Timeline around a timestamp
|
||||||
|
get_context_timeline with anchor="2025-11-06T10:30:00Z" and depth_before=15 and depth_after=5
|
||||||
|
```
|
||||||
|
|
||||||

|
|
||||||
|
### 9. get_timeline_by_query
|
||||||
|
|
||||||
|
Search for observations using natural language and get timeline context around the best match. Combines search + timeline into a single operation.
|
||||||
|
|
||||||
|
**Parameters**:
|
||||||
|
- `query` (required): Natural language search query to find relevant observations
|
||||||
|
- `mode` (default: "auto"): Operation mode
|
||||||
|
- `"auto"`: Automatically use top search result as timeline anchor
|
||||||
|
- `"interactive"`: Return top N search results for manual anchor selection
|
||||||
|
- `depth_before` (default: 10): Number of timeline records before anchor (max: 50)
|
||||||
|
- `depth_after` (default: 10): Number of timeline records after anchor (max: 50)
|
||||||
|
- `limit` (default: 5): For interactive mode - number of top search results to display (max: 20)
|
||||||
|
- `project`: Filter by project name
|
||||||
|
|
||||||
|
**Use Case**: Faster context discovery - "show me what happened around when we fixed the authentication bug"
|
||||||
|
|
||||||
|
**Example - Auto Mode**:
|
||||||
|
```
|
||||||
|
# Automatically find and show timeline for "authentication bug"
|
||||||
|
get_timeline_by_query with query="authentication bug" and mode="auto" and depth_before=10 and depth_after=10
|
||||||
|
```
|
||||||
|
|
||||||
|
**Example - Interactive Mode**:
|
||||||
|
```
|
||||||
|
# Show top 5 matches, let user choose anchor
|
||||||
|
get_timeline_by_query with query="authentication bug" and mode="interactive" and limit=5

## Context Injection Configuration
|

|
### CLAUDE_MEM_CONTEXT_OBSERVATIONS
|
||||||
|
|
||||||
|
Controls how many observations are injected into each new session for context continuity.
|
||||||
|
|
||||||
|
**Default**: 50 observations
|
||||||
|
|
||||||
|
**What it does**:
|
||||||
|
- Fetches the most recent N observations from the database
|
||||||
|
- Injects them as context at SessionStart
|
||||||
|
- Allows Claude to maintain awareness of recent work across sessions
|
||||||
|
|
||||||
|
**Configuration** in `~/.claude/settings.json`:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"env": {
|
||||||
|
"CLAUDE_MEM_CONTEXT_OBSERVATIONS": "100"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Considerations**:
|
||||||
|
- **Higher values** = More context but slower SessionStart and more tokens used
|
||||||
|
- **Lower values** = Faster SessionStart but less historical awareness
|
||||||
|
- Default of 50 balances context richness with performance
|
||||||
|
|
||||||
|
**Note**: This injects individual observations, not entire sessions. Each observation represents a single tool execution (Read, Write, Edit, etc.) that was compressed into a semantic learning.

## Viewer UI Development
|
||||||
|
|
||||||
|
### Working with the React Viewer
|
||||||
|
|
||||||
|
The web viewer UI is a React application built into a self-contained HTML bundle.
|
||||||
|
|
||||||
|
**Location**: `src/ui/viewer/`
|
||||||
|
|
||||||
|
**Structure**:

|
||||||
|
|
||||||
|
### Building Viewer UI
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Build everything including viewer
|
||||||
|
npm run build
|
||||||
|
|
||||||
|
# The viewer is built to plugin/ui/viewer.html
|
||||||
|
# It's a self-contained HTML file with inlined JS and CSS
|
||||||
|
```
|
||||||
|
|
||||||
|
### Testing Viewer Changes
|
||||||
|
|
||||||
|
1. Make changes to React components in `src/ui/viewer/`
|
||||||
|
2. Build: `npm run build`
|
||||||
|
3. Sync to installed plugin: `npm run sync-marketplace`
|
||||||
|
4. Restart worker: `npm run worker:restart`
|
||||||
|
5. Refresh browser at http://localhost:37777
|
||||||
|
|
||||||
|
**Hot Reload**: Not currently supported. Full rebuild + restart required for changes.
|
||||||
|
|
||||||
|
### Adding New Viewer Features
|
||||||
|
|
||||||
|
**Example: Adding a new card type**
|
||||||
|
|
||||||
|
1. Create component in `src/ui/viewer/components/cards/YourCard.tsx`:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import React from 'react';
|
||||||
|
|
||||||
|
export interface YourCardProps {
|
||||||
|
// Your data structure
|
||||||
|
}
|
||||||
|
|
||||||
|
export const YourCard: React.FC<YourCardProps> = ({ ... }) => {
|
||||||
|
return (
|
||||||
|
<div className="card">
|
||||||
|
{/* Your UI */}
|
||||||
|
</div>
|
||||||
|
);
|
||||||
|
};
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Import and use in `Feed.tsx`:
|
||||||
|
|
||||||
|
```tsx
|
||||||
|
import { YourCard } from './cards/YourCard';
|
||||||
|
|
||||||
|
// In render logic:
|
||||||
|
{item.type === 'your_type' && <YourCard {...item} />}
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Update types if needed in `src/ui/viewer/types.ts`
|
||||||
|
|
||||||
|
4. Rebuild and test
|
||||||
|
|
||||||
|
### Viewer UI Architecture
|
||||||
|
|
||||||
|
**Data Flow**:
|
||||||
|
1. Worker service exposes HTTP + SSE endpoints
|
||||||
|
2. React app fetches initial data via HTTP (paginated)
|
||||||
|
3. SSE connection provides real-time updates
|
||||||
|
4. Custom hooks handle state management and data merging
|
||||||
|
5. Components render cards based on item type
|
||||||
|
|
||||||
|
**Key Patterns**:
|
||||||
|
- **Infinite Scroll**: `usePagination` hook with Intersection Observer
|
||||||
|
- **Real-Time Updates**: `useSSE` hook with auto-reconnection
|
||||||
|
- **Deduplication**: `merge.ts` utilities prevent duplicate items
|
||||||
|
- **Settings Persistence**: `useSettings` hook with localStorage
|
||||||
|
- **Theme Support**: CSS variables with light/dark/system themes
|
||||||

## The Five Hooks
|
## The Seven Hook Scripts
|
||||||
|
|
||||||
### Hook 1: SessionStart (Context Hook)
|
Claude-Mem uses 7 hook scripts across 5 lifecycle events. SessionStart runs 3 hooks in sequence.
|
||||||
|
|
||||||
**Purpose:** Inject relevant context from previous sessions
|
### Hook 1: SessionStart - Smart Install
|
||||||
|
|
||||||
**When:** Claude Code starts or resumes
|
**Purpose:** Intelligently manage dependencies and start worker service
|
||||||
|
|
||||||
|
**When:** Claude Code starts (startup, clear, or compact)
|
||||||
|
|
||||||
**What it does:**
|
**What it does:**
|
||||||
1. Extracts project name from current working directory
|
1. Checks if dependencies need installation (version marker)
|
||||||
2. Queries SQLite for recent session summaries (last 10)
|
2. Only runs `npm install` when necessary:
|
||||||
3. Queries SQLite for recent observations (last 50)
|
- First-time installation
|
||||||
4. Formats as progressive disclosure index
|
- Version changed in package.json
|
||||||
5. Outputs to stdout (automatically injected into context)
|
- Critical dependency missing (better-sqlite3)
|
||||||
|
3. Provides Windows-specific error messages
|
||||||
|
4. Starts PM2 worker service
|
||||||

**Why smart-install is sometimes slow:**
|

- npm install check (idempotent but runs every time)

- First-time: Full npm install (2-5 seconds)
|
||||||
- Database query for 10 sessions + 50 observations
|
- Cached: Version check only (~10ms)
|
||||||
- Formatting progressive disclosure index
|
- Version change: Full npm install + PM2 restart
|
||||||
|
|
||||||
**Optimization (v4.3.1):**
|
**Optimization (v5.0.3):**
|
||||||
- Use `--loglevel=silent` for npm install
|
- Version caching with `.install-version` marker
|
||||||
- Cache package.json hash to skip unnecessary installs
|
- Only install on version change or missing deps
|
||||||
- Use prepared statements for database queries
|
- Windows-specific error messages with build tool help

## v5.x Specific Issues
|
||||||
|
|
||||||
|
### Viewer UI Not Loading
|
||||||
|
|
||||||
|
**Symptoms**: Cannot access http://localhost:37777, page doesn't load, or shows connection error.
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
|
||||||
|
1. Check if worker is running on port 37777:
|
||||||
|
```bash
|
||||||
|
lsof -i :37777
|
||||||
|
# or
|
||||||
|
npm run worker:status
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Verify worker is healthy:
|
||||||
|
```bash
|
||||||
|
curl http://localhost:37777/health
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Check worker logs for errors:
|
||||||
|
```bash
|
||||||
|
npm run worker:logs
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Restart worker service:
|
||||||
|
```bash
|
||||||
|
npm run worker:restart
|
||||||
|
```
|
||||||
|
|
||||||
|
5. Check for port conflicts:
|
||||||
|
```bash
|
||||||
|
# If port 37777 is in use by another service
|
||||||
|
export CLAUDE_MEM_WORKER_PORT=38000
|
||||||
|
npm run worker:restart
|
||||||
|
```
|
||||||
|
|
||||||
|
### Theme Toggle Not Persisting
|
||||||
|
|
||||||
|
**Symptoms**: Theme preference (light/dark mode) resets after browser refresh.
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
|
||||||
|
1. Check browser localStorage is enabled:
|
||||||
|
```javascript
|
||||||
|
// In browser console
|
||||||
|
localStorage.getItem('claude-mem-settings')
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Verify settings endpoint is working:
|
||||||
|
```bash
|
||||||
|
curl http://localhost:37777/api/settings
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Clear localStorage and try again:
|
||||||
|
```javascript
|
||||||
|
// In browser console
|
||||||
|
localStorage.removeItem('claude-mem-settings')
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Check for browser privacy mode (blocks localStorage)
|
||||||
|
|
||||||
|
### SSE Connection Issues
|
||||||
|
|
||||||
|
**Symptoms**: Viewer shows "Disconnected" status, updates not appearing in real-time.
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
|
||||||
|
1. Check SSE endpoint is accessible:
|
||||||
|
```bash
|
||||||
|
curl -N http://localhost:37777/stream
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Check browser console for errors:
|
||||||
|
- Open DevTools (F12)
|
||||||
|
- Look for EventSource errors
|
||||||
|
- Check Network tab for failed /stream requests
|
||||||
|
|
||||||
|
3. Verify worker is running:
|
||||||
|
```bash
|
||||||
|
npm run worker:status
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Check for network/proxy issues blocking SSE
|
||||||
|
- Corporate firewalls may block SSE
|
||||||
|
- Try disabling VPN temporarily
|
||||||
|
|
||||||
|
5. Restart worker and refresh browser:
|
||||||
|
```bash
|
||||||
|
npm run worker:restart
|
||||||
|
```
|
||||||
|
|
||||||
|
### Chroma/Python Dependency Issues (v5.0.0+)
|
||||||
|
|
||||||
|
**Symptoms**: Installation fails with chromadb or Python-related errors.
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
|
||||||
|
1. Verify Python 3.8+ is installed:
|
||||||
|
```bash
|
||||||
|
python --version
|
||||||
|
# or
|
||||||
|
python3 --version
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Install chromadb manually:
|
||||||
|
```bash
|
||||||
|
cd ~/.claude/plugins/marketplaces/thedotmack
|
||||||
|
npm install chromadb
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Check chromadb health:
|
||||||
|
```bash
|
||||||
|
npm run chroma:health
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Windows-specific: Ensure Python is in PATH:
|
||||||
|
```bash
|
||||||
|
where python
|
||||||
|
# Should show Python installation path
|
||||||
|
```
|
||||||
|
|
||||||
|
5. If Chroma continues to fail, hybrid search will gracefully degrade to SQLite FTS5 only
|
||||||
|
|
||||||
|
### Smart Install Caching Issues (v5.0.3+)
|
||||||
|
|
||||||
|
**Symptoms**: Dependencies not updating after plugin update, stale version marker.
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
|
||||||
|
1. Clear install cache:
|
||||||
|
```bash
|
||||||
|
rm ~/.claude/plugins/marketplaces/thedotmack/.install-version
|
||||||
|
```
|
||||||
|
|
||||||
|
2. Force reinstall:
|
||||||
|
```bash
|
||||||
|
cd ~/.claude/plugins/marketplaces/thedotmack
|
||||||
|
npm install --force
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Check version marker:
|
||||||
|
```bash
|
||||||
|
cat ~/.claude/plugins/marketplaces/thedotmack/.install-version
|
||||||
|
cat ~/.claude/plugins/marketplaces/thedotmack/package.json | grep version
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Restart Claude Code after manual install
|
||||||
|
|
||||||
|
### PM2 ENOENT Error on Windows (v5.1.1 Fix)
|
||||||
|
|
||||||
|
**Symptoms**: Worker fails to start with "ENOENT" error on Windows.
|
||||||
|
|
||||||
|
**Solutions**:
|
||||||
|
|
||||||
|
1. This was fixed in v5.1.1 - update to latest version:
|
||||||
|
```bash
|
||||||
|
/plugin update claude-mem
|
||||||
|
```
|
||||||
|
|
||||||
|
2. If still experiencing issues, verify PM2 path:
|
||||||
|
```bash
|
||||||
|
cd ~/.claude/plugins/marketplaces/thedotmack
|
||||||
|
dir node_modules\.bin\pm2.cmd
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Manual PM2 install if needed:
|
||||||
|
```bash
|
||||||
|
npm install pm2@latest
|
||||||
|
```

### get_context_timeline
|
||||||
|
|
||||||
|
Get a unified timeline of context around a specific point in time. This tool interleaves observations, sessions, and user prompts chronologically to show what was happening before and after a specific moment.
|
||||||
|
|
||||||
|
**Anchor by observation ID:**
|
||||||
|
```
|
||||||
|
get_context_timeline with anchor=12345 and depth_before=10 and depth_after=10
|
||||||
|
```
|
||||||
|
|
||||||
|
**Anchor by session ID:**
|
||||||
|
```
|
||||||
|
get_context_timeline with anchor="S123" and depth_before=5 and depth_after=5
|
||||||
|
```
|
||||||
|
|
||||||
|
**Anchor by ISO timestamp:**
|
||||||
|
```
|
||||||
|
get_context_timeline with anchor="2025-10-21T14:30:00Z" and depth_before=15 and depth_after=15
|
||||||
|
```
|
||||||
|
|
||||||
|
**Use cases:**
|
||||||
|
- Understand what was happening when a specific observation occurred
|
||||||
|
- See the full context around a bug fix or decision
|
||||||
|
- Trace the events leading up to and following a specific change
|
||||||
|
- View chronological sequence of related work
|
||||||
|
|
||||||
|
**Benefits:**
|
||||||
|
- All record types (observations, sessions, prompts) in one chronological view
|
||||||
|
- Configurable depth before/after anchor point
|
||||||
|
- Flexible anchoring by ID or timestamp
|
||||||
|
- See the complete narrative arc around key events
|
||||||
|
|
||||||
|
### get_timeline_by_query
|
||||||
|
|
||||||
|
Search for observations using natural language and get timeline context around the best match. This combines search + timeline into a single operation for faster context discovery.
|
||||||
|
|
||||||
|
**Auto mode (default):**
|
||||||
|
```
|
||||||
|
get_timeline_by_query with query="authentication implementation"
|
||||||
|
```
|
||||||
|
Automatically uses the top search result as timeline anchor and returns surrounding context.
|
||||||
|
|
||||||
|
**Interactive mode:**
|
||||||
|
```
|
||||||
|
get_timeline_by_query with query="authentication" and mode="interactive" and limit=5
|
||||||
|
```
|
||||||
|
Shows top 5 search results for you to manually choose which to use as timeline anchor.
|
||||||
|
|
||||||
|
**Customize timeline depth:**
|
||||||
|
```
|
||||||
|
get_timeline_by_query with query="bug fix" and depth_before=20 and depth_after=10
|
||||||
|
```
|
||||||
|
|
||||||
|
**Use cases:**
|
||||||
|
- Quick context discovery: "What was happening when we implemented X?"
|
||||||
|
- Investigate issues: Find a bug fix and see what led to it
|
||||||
|
- Decision archaeology: Search for a decision and understand the context
|
||||||
|
- Feature timeline: See the complete story of a feature implementation
|
||||||
|
|
||||||
|
**Benefits:**
|
||||||
|
- Single-step operation (no need to search, then timeline separately)
|
||||||
|
- Auto mode provides instant context
|
||||||
|
- Interactive mode gives you control over anchor selection
|
||||||
|
- Natural language search makes it easy to find relevant moments
