Amplifier

30+ specialized AI agents and a knowledge management system for your codebase.

Overview

Amplifier extends the IDE with specialized AI agents, each trained for specific tasks. Instead of one general-purpose AI, you get experts in architecture, security, testing, and more. Amplifier also maintains a knowledge graph of your codebase for context-aware assistance.

AI Agents

Built-in Agents (30+)

Agents are organized by category:

Analysis & Debugging (4 agents)

Architecture & Design (6 agents)

Content & Research (5 agents)

Building & Development (7 agents)

Knowledge & Synthesis (5 agents)

Meta Tools (3 agents)

Using Agents

1. Open the Amplifier panel in the sidebar
2. Browse or search for an agent
3. Click to activate
4. The agent’s expertise is now available in chat

Or mention an agent in chat:

@zen-architect Should we use microservices for this project?

Knowledge Base

Amplifier builds and maintains a knowledge graph of your codebase.

Features

Query Knowledge Ask questions about your code:

• “Where is authentication handled?”
• “What patterns does this codebase use?”
• “How do these modules interact?”

Update Knowledge Refresh the index when code changes significantly:

• After major refactors
• When adding new modules
• After pulling large changes

View Graph Visualize code relationships:

• Module dependencies
• Function call graphs
• Import/export relationships
• Data flow paths

Show Statistics Track codebase metrics:

• Files indexed
• Functions documented
• Test coverage
• Complexity scores

Keeping Knowledge Fresh

Knowledge updates automatically as you work, but you can force a refresh:

1. Open Knowledge Base in Amplifier
2. Click Update Knowledge
3. Wait for indexing to complete

CLI Integration

Connect Amplifier to external AI CLIs for expanded capabilities.

Supported CLIs

Switching CLIs

1. Click the CLI selector at the top of Amplifier
2. Choose your preferred CLI
3. The selected CLI handles agent tasks

CLI Status

See availability and version:

• claude ✓ Available (2.0.72)
• codex ✓ Available (codex-cli 0.72.0)
• gemini ✓ Available (0.20.2)

Worktrees

Manage multiple working directories for parallel development.

Creating Worktrees

1. Open Worktrees in Amplifier
2. Click Create Worktree
3. Name it and select a branch
4. A new isolated workspace is created

Use Cases

• Feature branches - Work on features in isolation
• Bug fixes - Hot-fix without disturbing main work
• Experiments - Try things without affecting your branch
• Code review - Check out PRs in separate worktrees

Managing Worktrees

• List All - See all active worktrees
• Switch Worktree - Change to a different worktree
• Delete - Remove worktrees you no longer need

Best Practices

Choosing the Right Agent

Combining Agents

Use multiple agents together:

@zen-architect @security-architect
Review this authentication system design.
Consider both architecture and security.

When to Update Knowledge

• After cloning a new repo
• After large merges or rebases
• When AI seems to have stale context
• Weekly for active projects
