```
### Design Principles
1. **Portability**: No hardcoded paths; runtime resolution
2. **Minimal Overhead**: <100ms total hook overhead
3. **Graceful Degradation**: Hooks never block main flow
4. **Learning by Default**: Automatic pattern improvement
5. **Cross-Platform**: Linux, macOS, Windows support
---
## Component Architecture
### CLI Layer (`crates/ruvector-cli`)
The command-line interface for hook management.
```

│ ├── cli/
│ │ ├── commands.rs # Command definitions
│ │ ├── hooks/ # Hooks subcommands

├── templates/ # Hook templates
│ ├── hooks.json.j2 # Portable hooks template
│ ├── config.toml.j2 # Configuration template
│ └── gitignore.j2 # Gitignore template
└── Cargo.toml
```
### Template Engine
Uses Askama for type-safe template rendering:
```rust
#[derive(Template)]
#[template(path = "hooks.json.j2")]
struct HookTemplate {
shell: String, // Platform shell wrapper
ruvector_cli: String, // CLI invocation method
project_root: String, // Project root path
}
fn render_hooks() -> Result<String> {
let template = HookTemplate {
shell: get_shell_wrapper(),
ruvector_cli: get_cli_invocation(),
project_root: env::current_dir()?.display().to_string(),
};
Ok(template.render()?)
}
```
### Path Resolution
Dynamic path resolution at runtime:
```rust
pub fn get_ruvector_home() -> Result<PathBuf> {
// Priority order:
// 1. RUVECTOR_HOME environment variable
// 2. ~/.ruvector (Unix) or %APPDATA%\ruvector (Windows)
if let Ok(home) = env::var("RUVECTOR_HOME") {
return Ok(PathBuf::from(shellexpand::tilde(&home).to_string()));
}
let home_dir = dirs::home_dir()
.ok_or_else(|| anyhow!("Could not determine home directory"))?;
Ok(home_dir.join(".ruvector"))
}
pub fn get_cli_path() -> Result<String> {
// Priority order:
// 1. Binary in PATH
// 2. npx ruvector
// 3. Current executable
if let Ok(path) = which::which("ruvector") {
return Ok(path.display().to_string());
}
Ok("npx ruvector".to_string())
}
```
---
## Intelligence Layer
### Q-Learning Engine
Implements temporal difference learning for action selection:
```javascript
// Q-value update equation
// Q(s,a) ← Q(s,a) + α[r + γ max_a' Q(s',a') - Q(s,a)]
class QLearning {
constructor(options = {}) {
this.alpha = options.learningRate || 0.1; // Learning rate
this.gamma = options.discount || 0.95; // Discount factor
this.qTable = new Map(); // State-action values
}
update(state, action, reward, nextState) {
const currentQ = this.getQ(state, action);
const maxNextQ = this.getMaxQ(nextState);
const newQ = currentQ + this.alpha * (reward + this.gamma * maxNextQ - currentQ);
this.setQ(state, action, newQ);
}
selectAction(state) {
// Epsilon-greedy exploration
if (Math.random() < this.epsilon) {
return this.randomAction(state);
}
return this.bestAction(state);
}
}
```
### State Representation
States encode file context and action type:
```javascript
function encodeState(context) {
const { file, crate, tool, previousSuccess } = context;
return {
fileType: getFileExtension(file), // 'rs', 'ts', 'py'
crateName: crate || 'unknown', // 'ruvector-core'
toolCategory: categorize(tool), // 'edit', 'bash', 'search'
historyHash: hashRecent(previousSuccess), // Recent success pattern
};
}
// State key for Q-table lookup
function stateKey(state) {
return `${state.toolCategory}_${state.fileType}_in_${state.crateName}`;
}
```
### Vector Memory
Semantic search using HNSW indexing:
```javascript
class VectorMemory {
constructor(dimensions = 128) {
this.dimensions = dimensions;
this.index = new HnswIndex({ dimensions, maxElements: 50000 });
this.metadata = new Map();
}
async store(key, text, metadata) {
const embedding = await this.embed(text);
const id = this.index.add(embedding);
this.metadata.set(id, { key, ...metadata });
return id;
}
async search(query, k = 5) {
const embedding = await this.embed(query);
const results = this.index.search(embedding, k);
return results.map(r => ({
...this.metadata.get(r.id),
distance: r.distance
}));
}
async embed(text) {
// Simple embedding: TF-IDF + dimensionality reduction
// Production: Use sentence-transformers or similar
return textToEmbedding(text, this.dimensions);
}
}
```
### Agent Router
Intelligent agent assignment based on context:
```javascript
class AgentRouter {
constructor(qLearning, vectorMemory) {
this.q = qLearning;
this.memory = vectorMemory;
this.agentTypes = loadAgentTypes();
}
async route(context) {
const state = encodeState(context);
// 1. Check Q-learning suggestion
const qSuggestion = this.q.selectAction(state);
const qConfidence = this.q.getQ(state, qSuggestion);
// 2. Check similar past edits
const similar = await this.memory.search(context.file, 3);
const historyAgent = this.majorityVote(similar);
// 3. Apply file type heuristics
const heuristicAgent = this.fileTypeHeuristic(context.file);
// 4. Combine signals
return this.combine({
q: { agent: qSuggestion, confidence: qConfidence },
history: { agent: historyAgent, confidence: similar.length / 3 },
heuristic: { agent: heuristicAgent, confidence: 0.5 }
});
}
fileTypeHeuristic(file) {
const ext = path.extname(file);
const mapping = {
'.rs': 'rust-developer',
'.ts': 'typescript-developer',
'.tsx': 'react-developer',
'.py': 'python-developer',
'.go': 'go-developer',
'.sql': 'database-specialist',
};
return mapping[ext] || 'coder';
}
}
```

```
---
## Integration Points
### Claude Code Integration
Hook configuration in `.claude/settings.json`:
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "pattern", // Regex for tool name
"hooks": [{
"type": "command", // Shell command
"command": "...", // Command to execute
"timeout": 3000 // Timeout in ms
}]
}],
"PostToolUse": [...],
"SessionStart": [...],
"Stop": [...] // Session end
}
}
```
### Claude-Flow Integration
MCP tool coordination:
```javascript
// Pre-task hook with MCP
async function preTask(description) {
// Store in coordination memory
await mcp__claude_flow__memory_usage({
action: "store",
key: "swarm/task/current",
namespace: "coordination",
value: JSON.stringify({ description, started: Date.now() })
});
// Spawn recommended agents
const agents = analyzeTaskNeeds(description);
for (const agent of agents) {
await mcp__claude_flow__agent_spawn({ type: agent });
}
}
```
### Git Integration
Pre-commit hook example:
```bash
#!/bin/bash
# .git/hooks/pre-commit
# Run RuVector pre-edit on staged files
FILES=$(git diff --cached --name-only --diff-filter=ACM)
for FILE in $FILES; do
RESULT=$(npx ruvector hooks pre-edit --file "$FILE" --validate-syntax)
CONTINUE=$(echo "$RESULT" | jq -r '.continue')
if [ "$CONTINUE" = "false" ]; then
echo "Pre-edit hook blocked: $FILE"
echo "$RESULT" | jq -r '.reason'
exit 1
fi
done
```
---
## Security Model
### Command Injection Prevention
All user inputs are escaped:
```rust
use shell_escape::escape;
fn generate_hook_command(file_path: &str) -> String {
let escaped = escape(file_path.into());
format!(
r#"/bin/bash -c 'npx ruvector hooks pre-edit --file {}'"#,
escaped
)
}
// Prevents: "; rm -rf /" attacks
// file_path = "test.ts; rm -rf /"
// escaped = "'test.ts; rm -rf /'" (treated as literal string)
```
### Timeout Protection
Hooks cannot hang indefinitely:
```javascript
async function executeHookSafely(hook, timeout = 3000) {
const controller = new AbortController();
const timeoutId = setTimeout(() => controller.abort(), timeout);
try {
const result = await executeHook(hook, { signal: controller.signal });
clearTimeout(timeoutId);
return result;
} catch (error) {
if (error.name === 'AbortError') {
console.warn('Hook timeout, continuing...');
return { continue: true, reason: 'timeout' };
}
throw error;
}
}
```
### Graceful Failure
Hooks never block tool execution:
```javascript
async function runPreHook(tool, context) {
try {
const result = await executeHookSafely(hook);
return result.continue !== false;
} catch (error) {
console.warn(`Hook failed: ${error.message}`);
return true; // Continue on error
}
}
```
---
## Performance Optimization
### Caching Strategy
```javascript
class IntelligenceCache {
constructor(maxAge = 300000) { // 5 minutes
this.cache = new Map();
this.maxAge = maxAge;
}
get(key) {
const entry = this.cache.get(key);
if (!entry) return null;
if (Date.now() - entry.timestamp > this.maxAge) {
this.cache.delete(key);
return null;
}
return entry.value;
}
set(key, value) {
this.cache.set(key, { value, timestamp: Date.now() });
}
}
// Cache agent routing decisions
const routingCache = new IntelligenceCache();
async function getAgent(file) {
const cached = routingCache.get(file);
if (cached) return cached;
const agent = await computeAgent(file);
routingCache.set(file, agent);
return agent;
}
```
### Async Operations
Non-blocking post-hooks:
```javascript
// Fire-and-forget for training
function postEditHook(file, success) {
// Synchronous: quick response
const response = { continue: true, formatted: true };
// Async: training (non-blocking)
setImmediate(() => {
trainPatterns(file, success).catch(console.warn);
updateMemory(file).catch(console.warn);
recordTrajectory(file, success).catch(console.warn);
});
return response;
}
```
### Batch Operations
Reduce I/O with batching:
```javascript
class BatchWriter {
constructor(flushInterval = 5000) {
this.queue = [];
this.interval = setInterval(() => this.flush(), flushInterval);
}
add(item) {
this.queue.push(item);
}
async flush() {
if (this.queue.length === 0) return;
const batch = this.queue.splice(0);
await fs.appendFile(
'trajectories.json',
batch.map(JSON.stringify).join('\n') + '\n'
);
}
}
const trajectoryWriter = new BatchWriter();
```
### Performance Targets
| Operation | Target | Typical |
|-----------|--------|---------|
| Pre-edit hook | <50ms | 30ms |
| Post-edit hook | <100ms | 60ms |
| Session start | <200ms | 150ms |
| Memory search | <10ms | 5ms |
| Q-value lookup | <1ms | 0.1ms |
| Total overhead | <100ms | 70ms |

- **Validation** of migrated data
- **Atomic operations** with rollback capability
- **Zero data loss** guarantee
---
## Migration Paths
### Quick Reference
| Source | Command | Time |
|--------|---------|------|
| Legacy `.claude/intelligence/` | `hooks migrate --from .claude/intelligence` | <5s |
| Claude-flow `memory.db` | `hooks migrate --from ~/.swarm/memory.db` | <10s |
| Exported JSON | `hooks import --input patterns.json` | <2s |
| Fresh start | `hooks init` | <1s |
### Prerequisites
Before migrating:
```bash
# 1. Backup existing data
cp -r .claude/intelligence .claude/intelligence.backup
cp -r ~/.swarm ~/.swarm.backup
# 2. Install latest RuVector CLI
npm install -g @ruvector/cli@latest
# 3. Verify installation
npx ruvector --version
```
---
## From Legacy Intelligence
Migrate from the repository-specific `.claude/intelligence/` system.
### Current Legacy Structure
```
.claude/
├── intelligence/
│ ├── data/
│ │ ├── memory.json # Vector memories
│ │ ├── trajectories.json # Learning history
│ │ ├── patterns.json # Q-learning patterns
│ │ └── feedback.json # User feedback
│ ├── index.js # Intelligence layer
│ └── cli.js # CLI commands
└── settings.json # Hardcoded hooks
```
### Migration Steps
#### Step 1: Initialize New System
```bash
npx ruvector hooks init
```
This creates:
```
.ruvector/
├── config.toml
├── intelligence/
│ └── (empty, ready for migration)
└── .gitignore
```
#### Step 2: Migrate Data
```bash
# Migrate with validation
npx ruvector hooks migrate \
--from .claude/intelligence \
--validate
# Expected output:
# Migrating from JSON files...
# ✓ Imported 1,247 trajectories
# ✓ Imported 89 Q-learning patterns
# ✓ Converted 543 memories to vectors
# ✓ Validation passed (100% integrity)
# ⏱ Completed in 3.2s
```
#### Step 3: Install New Hooks
```bash
# Install portable hooks
npx ruvector hooks install --force
# This replaces hardcoded paths with dynamic resolution
```
#### Step 4: Verify Migration
```bash
# Check statistics
npx ruvector hooks stats --verbose
# Should show migrated data:
# Patterns: 89
# Memories: 543
# Trajectories: 1,247
```
#### Step 5: Clean Up (Optional)
After confirming migration success:
```bash
# Remove legacy intelligence directory
rm -rf .claude/intelligence
# Keep backup for safety
# rm -rf .claude/intelligence.backup # Only if confident
```
### Legacy Settings.json Update
**Before (hardcoded):**
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "Bash",
"hooks": [{
"command": "/bin/bash -c 'cd /workspaces/ruvector/.claude/intelligence && node cli.js pre-command'"
}]
}]
}
}
```
**After (portable):**
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "Bash",
"hooks": [{
"command": "/bin/bash -c 'RUVECTOR=$(which ruvector || echo npx ruvector); $RUVECTOR hooks pre-command \"$CMD\"'"
}]
}]
}
}
```
---
## From Claude-Flow
Migrate from Claude-Flow's SQLite memory database.
### Claude-Flow Structure
```
~/.swarm/
├── memory.db # SQLite database
├── config.json # Configuration
└── sessions/ # Session data
```
### Migration Steps
#### Step 1: Locate Memory Database
```bash
# Default location
ls ~/.swarm/memory.db
# Custom location (check config)
cat ~/.swarm/config.json | jq '.memoryPath'
```
#### Step 2: Initialize RuVector
```bash
cd your-project
npx ruvector hooks init
```
#### Step 3: Migrate SQLite Data
```bash
# Migrate from SQLite
npx ruvector hooks migrate \
--from ~/.swarm/memory.db \
--format sqlite \
--validate
# Output:
# Migrating from SQLite database...
# ✓ Extracted 2,500 trajectories
# ✓ Converted 150 Q-learning patterns
# ✓ Migrated 1,200 memories to vectors
# ✓ Validation passed
```
**Note:** SQLite migration requires the `sqlite-migration` feature (v1.1+). For MVP, use JSON export:
```bash
# Alternative: Export from claude-flow first
npx claude-flow memory export --output memory-export.json
# Then import
npx ruvector hooks import --input memory-export.json
```
#### Step 4: Merge with Existing Data
If you have both legacy and claude-flow data:
```bash
# Merge with existing patterns
npx ruvector hooks migrate \
--from ~/.swarm/memory.db \
--merge \
--strategy average
```
#### Step 5: Install Hooks
```bash
npx ruvector hooks install
```
---
## From Manual Setup
Migrate from manually configured hooks.
### Current Manual Setup
**`.claude/settings.json` (manual):**
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "Write|Edit",
"hooks": [{
"type": "command",
"command": "echo 'Pre-edit hook'"
}]
}]
}
}
```
### Migration Steps
#### Step 1: Backup Existing Settings
```bash
cp .claude/settings.json .claude/settings.json.manual-backup
```
#### Step 2: Initialize RuVector
```bash
npx ruvector hooks init
```
#### Step 3: Install with Merge
```bash
# Merge RuVector hooks with existing
npx ruvector hooks install --merge
# This preserves your custom hooks and adds RuVector hooks
```
#### Step 4: Review Merged Settings
```bash
# View the merged settings
cat .claude/settings.json
# Verify your custom hooks are preserved
```
### Preserving Custom Hooks
If you have custom hooks to preserve:
**Before install:**
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "CustomTool",
"hooks": [{
"command": "my-custom-hook.sh"
}]
}]
}
}
```
**After install (merged):**
```json
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [{
"command": "npx ruvector hooks pre-command"
}]
},
{
"matcher": "CustomTool",
"hooks": [{
"command": "my-custom-hook.sh"
}]
}
]
}
}
```
---
## Data Preservation
### What Gets Migrated
| Data Type | Source | Destination |
|-----------|--------|-------------|
| Q-learning patterns | `patterns.json` | `.ruvector/intelligence/patterns.json` |
| Trajectories | `trajectories.json` | `.ruvector/intelligence/trajectories.json` |
| Vector memories | `memory.json` | `.ruvector/intelligence/memory.rvdb` |
| Feedback data | `feedback.json` | `.ruvector/intelligence/feedback.json` |
| Configuration | settings.json | `.ruvector/config.toml` |
### Data Integrity Checks
The migration process includes:
1. **Checksum validation**: Verify data wasn't corrupted
2. **Count verification**: Ensure all records migrated
3. **Q-value preservation**: Maintain learned values
4. **Vector accuracy**: Preserve embedding precision
### Backup Locations
Automatic backups are created:
```
.ruvector/
├── intelligence/
│ └── backup-YYYYMMDD-HHMMSS/
│ ├── patterns.json
│ ├── trajectories.json
│ └── memory.json
```
---
## Verification
### Verify Migration Success
```bash
# 1. Check statistics
npx ruvector hooks stats --verbose
# 2. Compare counts
echo "Legacy patterns: $(jq '.patterns | length' .claude/intelligence.backup/data/patterns.json 2>/dev/null || echo 0)"
echo "Migrated patterns: $(npx ruvector hooks stats --json | jq '.patterns')"
# 3. Test hook execution
npx ruvector hooks pre-edit --file test.ts
npx ruvector hooks post-edit --file test.ts --success true
# 4. Verify session hooks
npx ruvector hooks session-start --session-id "migration-test"
npx ruvector hooks session-end --session-id "migration-test"
```
### Expected Verification Output
```bash
$ npx ruvector hooks stats --verbose
RuVector Intelligence Statistics
================================
Data Migration Status: SUCCESS
Learning Data:
Trajectories: 1,247 (migrated: 1,247)
Patterns: 89 (migrated: 89)
Memories: 543 vectors (migrated: 543)
Integrity: 100%
Configuration:
Hooks installed: Yes
Portable paths: Yes
Intelligence enabled: Yes
```
### Test in Claude Code
1. Open Claude Code in your project
2. Verify session start message appears
3. Make an edit to a file
4. Confirm agent assignment message
5. Check post-edit formatting
---
## Rollback
### Automatic Rollback
If migration fails, automatic rollback occurs:
```bash
$ npx ruvector hooks migrate --from .claude/intelligence
Migrating from JSON files...
✓ Imported 1,247 trajectories
✗ Error during pattern migration: Invalid Q-value format
⟲ Rolling back migration...
✓ Restored from backup
Migration failed, original data preserved
```
### Manual Rollback
To manually rollback:
#### Step 1: Restore Backup
```bash
# Restore intelligence data
rm -rf .ruvector/intelligence
cp -r .ruvector/intelligence/backup-YYYYMMDD-HHMMSS/* .ruvector/intelligence/
# Or restore legacy location
rm -rf .ruvector
mv .claude/intelligence.backup .claude/intelligence
```
#### Step 2: Restore Settings
```bash
# Restore Claude settings
cp .claude/settings.json.backup .claude/settings.json
```
#### Step 3: Verify Restoration
```bash
# For legacy
node .claude/intelligence/cli.js stats
# For new system
npx ruvector hooks stats
```
### Complete Reset
To completely reset and start fresh:
```bash
# Remove all RuVector data
rm -rf .ruvector
# Remove from Claude settings
# Edit .claude/settings.json to remove hooks section
# Reinitialize
npx ruvector hooks init
npx ruvector hooks install
```
---
## Migration FAQ
### Q: Will I lose my learned patterns?
**A:** No. All migrations include automatic backup and validation. Q-values, trajectories, and memories are preserved with 100% integrity.
### Q: Can I migrate incrementally?
**A:** Yes. Use the `--merge` flag to add new data without replacing existing:
```bash
npx ruvector hooks migrate --from new-data.json --merge
```
### Q: What about Windows compatibility?
**A:** The new system uses conditional shell detection:
```bash
# Windows
cmd /c 'npx ruvector hooks ...'
# Linux/macOS
/bin/bash -c 'npx ruvector hooks ...'
```
### Q: How do I migrate a team project?
**A:** Export and share patterns:
```bash
# Team member 1: Export
npx ruvector hooks export --output team-patterns.json
# Team member 2: Import and merge
npx ruvector hooks import --input team-patterns.json --merge
```
### Q: Is the migration reversible?
**A:** Yes. Backups are automatically created and manual rollback is always possible.

## What Are Hooks?
Hooks are automated actions that execute before or after Claude Code tool operations. They enable:
- **Intelligent Agent Assignment**: Automatically assign the best agent for each file type
- **Code Quality**: Format, lint, and validate code automatically
- **Memory Persistence**: Store decisions and context across sessions
- **Neural Learning**: Continuously improve from successful patterns
- **Swarm Coordination**: Synchronize knowledge across multi-agent workflows

```
## Quick Start
### 1. Initialize Hooks
```bash
# Using npx (recommended)
npx ruvector hooks init
# Or using claude-flow
npx claude-flow init --hooks
```
### 2. Install into Claude Code
```bash
npx ruvector hooks install
```
### 3. Verify Setup
```bash
npx ruvector hooks stats
```
## Hook Types
### Pre-Operation Hooks
Execute **before** Claude Code operations:
| Hook | Trigger | Purpose |
|------|---------|---------|
| `pre-edit` | Write, Edit, MultiEdit | Agent assignment, syntax validation |
| `pre-bash` | Bash commands | Safety checks, resource estimation |
| `pre-task` | Task spawning | Auto-spawn agents, load memory |
| `pre-search` | Grep, Glob | Cache checking, query optimization |
### Post-Operation Hooks
Execute **after** Claude Code operations:
| Hook | Trigger | Purpose |
|------|---------|---------|
| `post-edit` | Write, Edit, MultiEdit | Formatting, memory storage, training |
| `post-bash` | Bash commands | Logging, metrics, error detection |
| `post-task` | Task completion | Performance analysis, learning export |
| `post-search` | Grep, Glob | Caching, pattern improvement |
### Session Hooks
Manage session lifecycle:
| Hook | Trigger | Purpose |
|------|---------|---------|
| `session-start` | Session begins | Context loading, initialization |
| `session-restore` | Manual restore | Restore previous session state |
| `session-end` | Session ends | Persist state, export metrics |
## Configuration
Hooks are configured in `.claude/settings.json`:
```json
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [{
"type": "command",
"timeout": 3000,
"command": "npx ruvector hooks pre-command \"$CMD\""
}]
}
],
"PostToolUse": [
{
"matcher": "Write|Edit|MultiEdit",
"hooks": [{
"type": "command",
"command": "npx ruvector hooks post-edit \"$FILE\""
}]
}
],
"SessionStart": [
{
"hooks": [{
"type": "command",
"command": "npx ruvector hooks session-start"
}]
}
]
}
}
```
## Intelligence Layer
The hooks system includes a self-learning intelligence layer:
### Q-Learning Patterns
Learns optimal actions from experience:
- State-action pair tracking
- Reward-based learning
- Decay over time for relevance
### Vector Memory
Semantic search over past decisions:
- 128-dimensional embeddings
- HNSW indexing for fast retrieval
- Persistent storage with rvlite
### Agent Routing
Intelligent agent assignment:
- File type → agent type mapping
- Confidence scoring

---
## Installation Issues
### Problem: `hooks init` fails
**Symptoms:**
```
Error: Failed to create .ruvector directory
Permission denied
```
**Solutions:**
1. Check directory permissions:
```bash
ls -la .
# Ensure you have write access
```
2. Create directory manually:
```bash
mkdir -p .ruvector/intelligence
npx ruvector hooks init
```
3. Use sudo (last resort):
```bash
sudo npx ruvector hooks init
sudo chown -R $USER:$USER .ruvector
```
---
### Problem: `hooks install` doesn't update settings
**Symptoms:**
- `.claude/settings.json` unchanged
- Old hooks still running
**Solutions:**
1. Use `--force` flag:
```bash
npx ruvector hooks install --force
```
2. Check backup and restore:
```bash
# View backup
cat .claude/settings.json.backup
# If needed, restore and try again
cp .claude/settings.json.backup .claude/settings.json
npx ruvector hooks install --force
```
3. Manually edit settings:
```bash
# Open and verify hook section
code .claude/settings.json
```
---
### Problem: "npx ruvector" command not found
**Symptoms:**
```
npm ERR! could not determine executable to run
```
**Solutions:**
1. Install globally:
```bash
npm install -g @ruvector/cli
ruvector hooks init
```
2. Check npm configuration:
```bash
npm config get prefix
# Ensure this is in your PATH
```
3. Use npx with package:
```bash
npx @ruvector/cli hooks init
```
---
## Hook Execution Issues
### Problem: Hooks not triggering
**Symptoms:**
- No output when editing files
- Session start message missing
- Intelligence not active
**Diagnosis:**
```bash
# Check settings.json has hooks
cat .claude/settings.json | jq '.hooks'
# Should show PreToolUse, PostToolUse, etc.
```
**Solutions:**
1. Reinstall hooks:
```bash
npx ruvector hooks install --force
```
2. Check matcher patterns:
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "Bash", // Case-sensitive!
"hooks": [...]
}]
}
}
```
3. Verify Claude Code is loading settings:
```bash
# Restart Claude Code to reload settings
```
---
### Problem: Hook timeout
**Symptoms:**
```
Warning: Hook timeout after 3000ms
```
**Solutions:**
1. Increase timeout in settings:
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "Bash",
"hooks": [{
"timeout": 5000, // Increase to 5 seconds
"command": "..."
}]
}]
}
}
```
2. Check for slow operations:
```bash
# Time hook execution
time npx ruvector hooks pre-edit --file test.ts
```
3. Reduce hook complexity:
- Disable neural training in pre-hooks
- Use async for heavy operations
- Cache repeated lookups
---
### Problem: Hook blocks tool execution
**Symptoms:**
- Edit operations not completing
- "continue: false" in output
**Diagnosis:**
```bash
# Test hook directly
npx ruvector hooks pre-edit --file problematic-file.ts
# Check response
# { "continue": false, "reason": "..." }
```
**Solutions:**
1. Check protected files:
```bash
# If file is protected, you'll see:
# { "continue": false, "reason": "Protected file" }
# Add to exceptions in config.toml
[hooks]
protected_exceptions = [".env.local"]
```
2. Disable blocking:
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "Write",
"hooks": [{
"command": "...",
"continueOnError": true // Never block on error
}]
}]
}
}
```
---
## Intelligence Layer Issues
### Problem: No agent suggestions
**Symptoms:**
- `assignedAgent` always null
- No intelligence guidance
**Diagnosis:**
```bash
# Check intelligence status
npx ruvector hooks stats
# Expected output:
# Patterns: N
# Memories: N
# Status: Ready
```
**Solutions:**
1. Enable intelligence:
```bash
export RUVECTOR_INTELLIGENCE_ENABLED=true
```
2. Check data files exist:
```bash
ls -la .ruvector/intelligence/
# Should show patterns.json, memory.json, etc.
```
3. Initialize fresh data:
```bash
npx ruvector hooks init --force
```
---
### Problem: Poor agent suggestions
**Symptoms:**
- Wrong agent assigned to file types
- Low confidence scores
**Diagnosis:**
```bash
# Check patterns
npx ruvector hooks stats --verbose
# Look for:
# Top Patterns:
# 1. edit_rs_in_xxx → rust-developer (Q=0.82)
```
**Solutions:**
1. Reset learning data:
```bash
rm .ruvector/intelligence/patterns.json
rm .ruvector/intelligence/trajectories.json
# Will rebuild from scratch
```
2. Import team patterns:
```bash
npx ruvector hooks import --input team-patterns.json
```
3. Wait for learning:
- Patterns improve with use
- 50+ edits needed for good suggestions
---
### Problem: Memory search slow or failing
**Symptoms:**
- Memory search timeout
- "Error: Failed to load memory"
**Diagnosis:**
```bash
# Check memory size
ls -la .ruvector/intelligence/memory.json
# If >10MB, consider cleanup
```
**Solutions:**
1. Clean old memories:
```bash
# Backup first
cp .ruvector/intelligence/memory.json memory-backup.json
# Keep only recent
node -e "
const fs = require('fs');
const data = JSON.parse(fs.readFileSync('.ruvector/intelligence/memory.json'));
const recent = data.slice(-1000); // Keep last 1000
fs.writeFileSync('.ruvector/intelligence/memory.json', JSON.stringify(recent));
"
```
2. Rebuild HNSW index:
```bash
rm .ruvector/intelligence/memory.rvdb
# Will rebuild on next use
```
---
## Performance Issues
### Problem: High hook overhead
**Symptoms:**
- Slow file operations
- Noticeable delay on every edit
**Diagnosis:**
```bash
# Time individual hooks
time npx ruvector hooks pre-edit --file test.ts
time npx ruvector hooks post-edit --file test.ts --success true
# Target: <50ms each
```
**Solutions:**
1. Disable neural training:
```bash
# In config.toml
[intelligence]
neural_training = false
```
2. Reduce memory operations:
```toml
[hooks]
store_memory = false # Disable memory storage
```
3. Use async post-hooks:
```json
{
"hooks": {
"PostToolUse": [{
"matcher": "Write",
"hooks": [{
"command": "...",
"async": true // Don't wait for completion
}]
}]
}
}
```
---
### Problem: Large intelligence data files
**Symptoms:**
- `.ruvector/intelligence/` >100MB
- Slow startup
**Solutions:**
1. Set retention limits:
```toml
# In config.toml
[intelligence]
max_trajectories = 1000
max_memories = 10000
```
2. Clean old data:
```bash
# Export current patterns
npx ruvector hooks export --output patterns-backup.json --include patterns
# Reset
rm -rf .ruvector/intelligence/*
# Re-import patterns
npx ruvector hooks import --input patterns-backup.json
```
---
## Platform-Specific Issues
### Windows Issues
#### Problem: "/bin/bash not found"
**Symptoms:**
```
'/bin/bash' is not recognized as an internal or external command
```
**Solution:**
Check that hooks use Windows-compatible shell:
```json
{
"hooks": {
"PreToolUse": [{
"matcher": "Bash",
"hooks": [{
"command": "cmd /c 'npx ruvector hooks pre-command'"
}]
}]
}
}
```
Or reinstall hooks (auto-detects platform):
```bash
npx ruvector hooks install --force
```
#### Problem: Path separator issues
**Symptoms:**
- File paths not recognized
- "File not found" errors
**Solution:**
Ensure paths use forward slashes or escaped backslashes:
```bash
# Good
npx ruvector hooks pre-edit --file "src/app.ts"
# Bad on Windows
npx ruvector hooks pre-edit --file "src\app.ts"
```
#### Problem: jq not found
**Symptoms:**
```
'jq' is not recognized as an internal or external command
```
**Solutions:**
1. Install jq:
```bash
# Using chocolatey
choco install jq
# Using scoop
scoop install jq
```
2. Or use jq-free hooks:
```bash
npx ruvector hooks install --template minimal
```
---
### macOS Issues
#### Problem: Permission denied
**Symptoms:**
```
Error: EACCES: permission denied
```
**Solutions:**
1. Fix npm permissions:
```bash
sudo chown -R $(whoami) ~/.npm
```
2. Use nvm:
```bash
# Install nvm and use it for npm
nvm install node
nvm use node
```
---
### Linux Issues
#### Problem: Node.js version too old
**Symptoms:**
```
SyntaxError: Unexpected token '.'
```
**Solution:**
Update Node.js:
```bash
# Using nvm
nvm install 18
nvm use 18
# Or using package manager
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt-get install -y nodejs
```
---
## Migration Issues
### Problem: Migration data loss
**Symptoms:**
- Fewer patterns after migration
- Missing memories
**Diagnosis:**
```bash
# Compare counts
echo "Before: $(jq '.length' old-patterns.json)"
echo "After: $(npx ruvector hooks stats --json | jq '.patterns')"
```
**Solutions:**
1. Use validation:
```bash
npx ruvector hooks migrate --from old-data --validate
```
2. Merge instead of replace:
```bash
npx ruvector hooks migrate --from old-data --merge
```
3. Restore from backup:
```bash
cp .ruvector/intelligence/backup-*/* .ruvector/intelligence/
```
---
### Problem: SQLite migration format error
**Symptoms:**
```
Error: Unknown embedding format in memory.db
```
**Solution:**
SQLite migration requires format detection. For MVP, use JSON export:
```bash
# Export from source as JSON first
npx claude-flow memory export --output memory.json
# Then import
npx ruvector hooks import --input memory.json
```
---
## Debug Mode
### Enable Debug Output
```bash
# Set environment variable
export CLAUDE_FLOW_DEBUG=true
export RUVECTOR_DEBUG=true
# Run with debug
npx ruvector hooks pre-edit --file test.ts --debug
```
### Debug Output Interpretation
```
DEBUG: Loading config from .ruvector/config.toml
DEBUG: Intelligence enabled: true
DEBUG: Q-table loaded: 89 patterns
DEBUG: Memory loaded: 543 vectors
DEBUG: Encoding state for test.ts
DEBUG: State key: edit_ts_in_project
DEBUG: Q-values: { "typescript-developer": 0.82, "coder": 0.45 }
DEBUG: Selected agent: typescript-developer (confidence: 0.82)
```
### View Hook Logs
```bash
# Today's logs
cat .ruvector/logs/hooks-$(date +%Y-%m-%d).log
# Tail logs
tail -f .ruvector/logs/hooks-*.log
```
### Test Hooks Manually
```bash
# Test pre-edit
echo '{"tool_input":{"file_path":"test.ts"}}' | npx ruvector hooks pre-edit --stdin
# Test post-edit
echo '{"tool_input":{"file_path":"test.ts"},"tool_result":{"success":true}}' | npx ruvector hooks post-edit --stdin
```

---
## Quick Start
Get up and running in under 5 minutes:
```bash
# Step 1: Initialize hooks in your project
npx ruvector hooks init
# Step 2: Install hooks into Claude Code
npx ruvector hooks install
# Step 3: Verify installation
npx ruvector hooks stats
# Done! Hooks are now active
```
---
## Prerequisites
### Required
- **Node.js 18+**: Required for hook execution
- **Claude Code**: The hooks integrate with Claude Code's hook system
- **npm or pnpm**: Package manager for installation
### Optional
- **jq**: JSON processing for hook data (auto-installed on most systems)
- **Git**: For version control integration
- **claude-flow CLI**: For advanced swarm coordination
### Verify Prerequisites
```bash
# Check Node.js version
node --version # Should be 18.x or higher
# Check npm
npm --version
# Check jq (optional)
which jq || echo "jq not installed (optional)"
```
---
## Installation
### Method 1: npx (Recommended)
The simplest way to install hooks:
```bash
# Initialize in any project
cd your-project
npx ruvector hooks init
npx ruvector hooks install
```
### Method 2: Global Installation
For frequent use across projects:
```bash
# Install globally
npm install -g @ruvector/cli
# Then use directly
ruvector hooks init
ruvector hooks install
```
### Method 3: With Claude Flow
If using claude-flow for swarm coordination:
```bash
# Initialize with full hook support
npx claude-flow init --hooks
# Hooks are automatically configured
```
### Verify Installation
```bash
# Check hooks are installed
npx ruvector hooks stats
# Expected output:
# RuVector Intelligence Statistics
# --------------------------------
# Patterns: 0 (new installation)
# Memories: 0
# Status: Ready
```
---
## Basic Usage
### How Hooks Work
Hooks automatically execute when you use Claude Code:
1. **Pre-hooks** run before tool execution
2. **Post-hooks** run after tool execution
3. **Session hooks** run at session boundaries
### Automatic Behavior
Once installed, hooks work automatically:
```bash
# When you edit a file in Claude Code:
# 1. pre-edit hook checks file type, assigns agent
# 2. Claude Code performs the edit
# 3. post-edit hook formats code, stores in memory
# When you run a command:
# 1. pre-bash hook validates safety
# 2. Command executes
# 3. post-bash hook logs result, updates metrics
```
### Manual Hook Execution
You can also run hooks manually:
```bash
# Test pre-edit hook
npx ruvector hooks pre-edit --file "src/app.ts"
# Test post-edit hook
npx ruvector hooks post-edit --file "src/app.ts" --success true
# Run session hooks
npx ruvector hooks session-start
npx ruvector hooks session-end --export-metrics
```
---
## Configuration
### Configuration File
After `hooks init`, a configuration file is created:
**`.ruvector/config.toml`**:
```toml
[intelligence]
enabled = true
learning_rate = 0.1
ab_test_group = "treatment"
use_hyperbolic_distance = true
curvature = 1.0
[memory]
backend = "rvdb"
max_memories = 50000
dimensions = 128
[patterns]
decay_half_life_days = 7
min_q_value = -0.5
max_q_value = 0.8
[hooks]
pre_command_enabled = true
post_command_enabled = true
pre_edit_enabled = true
post_edit_enabled = true
session_start_enabled = true
session_end_enabled = true
timeout_ms = 3000
```
### Claude Code Settings
Hooks are registered in `.claude/settings.json`:
```json
{
"hooks": {
"PreToolUse": [
{
"matcher": "Bash",
"hooks": [{
"type": "command",
"timeout": 3000,
"command": "npx ruvector hooks pre-command \"$CMD\""
}]
},
{
"matcher": "Write|Edit|MultiEdit",
"hooks": [{
"type": "command",
"timeout": 3000,
"command": "npx ruvector hooks pre-edit \"$FILE\""
}]
}
],
"PostToolUse": [
{
"matcher": "Write|Edit|MultiEdit",
"hooks": [{
"type": "command",
"command": "npx ruvector hooks post-edit \"$FILE\" \"true\""
}]
}
],
"SessionStart": [
{
"hooks": [{
"type": "command",
"timeout": 5000,
"command": "npx ruvector hooks session-start"
}]
}
]
}
}
```
### Customizing Hooks
#### Add Protected File Detection
```json
{
"hooks": {
"PreToolUse": [
{
"matcher": "Write|Edit",
"hooks": [{
"type": "command",
"command": "npx ruvector hooks check-protected \"$FILE\""
}]
}
]
}
}
```
#### Add Auto-Testing
```json
{
"hooks": {
"PostToolUse": [
{
"matcher": "Write",
"hooks": [{
"type": "command",
"command": "test -f \"${FILE%.ts}.test.ts\" && npm test \"${FILE%.ts}.test.ts\"",
"continueOnError": true
}]
}
]
}
}
```
---
## Working with Hooks
### Pre-Edit Hook
Runs before file modifications:
```bash
npx ruvector hooks pre-edit --file "src/auth/login.ts"
```
**What it does:**
- Detects file type and language
- Assigns appropriate agent (e.g., TypeScript files → typescript-developer)
- Checks for existing patterns
- Validates syntax if enabled
- Creates backup if configured
**Output example:**
```json
{
"continue": true,
"agent": "typescript-developer",
"confidence": 0.85,
"syntaxValid": true,
"warnings": []
}
```
### Post-Edit Hook
Runs after file modifications:
```bash
npx ruvector hooks post-edit --file "src/auth/login.ts" --success true
```
**What it does:**
- Records successful edit in trajectory
- Updates Q-learning patterns
- Stores context in vector memory
- Optionally formats code
- Trains neural patterns
### Session Hooks
#### Starting a Session
```bash
npx ruvector hooks session-start --session-id "feature-dev"
```
**Output:**
```
RuVector Intelligence Layer Active
Patterns: 131 state-action pairs
Memories: 4,247 vectors
Status: Ready
```
#### Ending a Session
```bash
npx ruvector hooks session-end --export-metrics --generate-summary
```
**What it does:**
- Persists memory state
- Exports session metrics
- Generates work summary
- Cleans up temporary files
---
## Intelligence Features
### Q-Learning
The hooks system learns from your actions:
```bash
# View learned patterns
npx ruvector hooks stats --verbose
# Output:
# Top Patterns:
# 1. edit_ts_in_src → typescript-developer (Q=0.82)
# 2. edit_rs_in_crates → rust-developer (Q=0.79)
# 3. cargo_test → success (Q=0.91)
```
### Agent Routing
Automatically assigns the best agent for each file:
| File Type | Assigned Agent | Confidence |
|-----------|---------------|------------|
| `*.ts`, `*.tsx` | typescript-developer | 85% |
| `*.rs` | rust-developer | 80% |
| `*.py` | python-developer | 78% |
| `*.go` | go-developer | 75% |
| `*.sql` | database-specialist | 70% |
### Memory Persistence
Decisions are stored for future reference:
```bash
# Check memory usage
npx ruvector hooks stats
# Output:
# Memories: 4,247 vectors
# Dimensions: 128
# Storage: 2.4 MB
```
### A/B Testing
Compare learning effectiveness:
```bash
# Treatment group (learning enabled)
INTELLIGENCE_MODE=treatment npx ruvector hooks pre-edit --file "test.ts"
# Control group (random baseline)
INTELLIGENCE_MODE=control npx ruvector hooks pre-edit --file "test.ts"
```
---
## Best Practices
### 1. Initialize Early
Set up hooks at the start of a project:
```bash
# After creating a new project
npx ruvector hooks init
npx ruvector hooks install
```
### 2. Use Meaningful Session IDs
Track work with descriptive sessions:
```bash
# Good: Descriptive sessions
npx ruvector hooks session-start --session-id "feature-auth-oauth2"
npx ruvector hooks session-start --session-id "bugfix-memory-leak-123"
# Avoid: Generic sessions
npx ruvector hooks session-start --session-id "session1"
```
### 3. Export Metrics Regularly
Capture performance data:
```bash
# At end of work session
npx ruvector hooks session-end --export-metrics --generate-summary
```
### 4. Review Pattern Quality
Check learning effectiveness:
```bash
# Weekly review
npx ruvector hooks stats --verbose
# Check calibration
# Good: 0.04-0.06 calibration error
# Bad: >0.15 calibration error
```
### 5. Keep Hooks Lightweight
Follow performance guidelines:
- Hook execution: <50ms
- Total overhead: <100ms per operation
- Async heavy operations
- Cache repeated lookups
### 6. Use Version Control
Track hook configurations:
```bash
# Add to git
git add .claude/settings.json
git add .ruvector/config.toml
# Ignore learning data (optional)
echo ".ruvector/intelligence/" >> .gitignore
```
---
## Examples
### Example 1: Development Workflow
```bash
# Start development session
npx ruvector hooks session-start --session-id "feature-user-profile"
# Work on files (hooks run automatically via Claude Code)
# - Pre-edit assigns agents
# - Post-edit formats and stores
# End session
npx ruvector hooks session-end \
--session-id "feature-user-profile" \
--export-metrics \
--generate-summary
```
### Example 2: Debugging Session
```bash
# Start debug session
npx ruvector hooks session-start --session-id "debug-api-timeout"
# Load previous context
npx ruvector hooks session-restore --session-id "debug-api-timeout"
# Work on debugging...
# Export findings
npx ruvector hooks session-end \
--session-id "debug-api-timeout" \
--store-decisions \
--generate-report
```
### Example 3: Multi-Agent Task
```bash
# Pre-task with agent spawning
npx claude-flow hook pre-task \
--description "Implement OAuth2 authentication" \
--auto-spawn-agents \
--load-memory
# Agents work on files (hooks coordinate)
# Post-task analysis
npx claude-flow hook post-task \
