RuVector Hooks System Documentation

Intelligent hooks for Claude Code that provide automatic agent assignment, code formatting, neural pattern training, and cross-session memory persistence.

Implementation Status: ✅ FULLY IMPLEMENTED - Both implementations are now functional:

  • Rust CLI: ruvector hooks <command> (portable, high-performance)
  • Node.js: .claude/intelligence/cli.js (legacy compatibility)

Available Implementations

# Rust CLI (recommended - faster, portable)
cargo run --bin ruvector -- hooks stats
cargo run --bin ruvector -- hooks pre-edit <file>
cargo run --bin ruvector -- hooks post-edit <file> --success

# Node.js (legacy - still functional)
node .claude/intelligence/cli.js stats
node .claude/intelligence/cli.js pre-edit <file>

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

# Using npx (recommended)
npx ruvector hooks init

# Or using claude-flow
npx claude-flow init --hooks

2. Install into Claude Code

npx ruvector hooks install

3. Verify Setup

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 / Stop Session ends Persist state, export metrics

Compact Hooks

Execute during context compaction:

Hook Matcher Purpose
PreCompact manual Display learned patterns during manual compact
PreCompact auto Show learning stats during auto-compact

Hooks are configured in .claude/settings.json:

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
  • Fallback strategies

Directory Structure

After initialization:

.ruvector/
├── config.toml              # Project configuration
├── intelligence/
│   ├── memory.json          # Vector memory entries
│   ├── patterns.json        # Q-learning patterns
│   ├── trajectories.json    # Learning trajectories
│   ├── feedback.json        # User feedback tracking
│   └── memory.rvdb          # RvLite vector database
└── .gitignore

Environment Variables

Variable Default Description
RUVECTOR_HOME ~/.ruvector Global patterns directory
RUVECTOR_DATA_DIR ./.ruvector Project-local data
RUVECTOR_INTELLIGENCE_ENABLED true Enable/disable intelligence
INTELLIGENCE_MODE treatment A/B test group

Performance

The hooks system is designed for minimal overhead:

  • Hook execution: <50ms typical
  • Memory lookup: <10ms with HNSW
  • Pattern training: Async, non-blocking
  • Total overhead: <100ms per operation

Integration

Hooks integrate with:

  • Claude Code: Native tool hooks
  • Claude Flow: MCP swarm coordination
  • Git: Pre-commit and post-commit hooks
  • RvLite: Vector database storage
  • Neural Training: Pattern improvement
