Agent Registry

Lazy-loading system for Claude Code agents. Eliminates the "~16k tokens" warning by loading agents on-demand.

CRITICAL RULE

NEVER assume agents are pre-loaded. Always use this registry to discover and load agents.

Workflow

User Request → search_agents(intent) → select best match → get_agent(name) → execute with agent

Available Commands

Search First Pattern

1. Extract intent keywords from user request
2. Run search: bun bin/search.js "<keywords>"
3. Review results: Check relevance scores (0.0-1.0)
4. Load if needed: bun bin/get.js <agent-name>
5. Execute: Follow the loaded agent's instructions

Example

User: "Can you review my authentication code for security issues?"

# Step 1: Search for relevant agents
bun bin/search.js "code review security authentication"

# Output:
# Found 2 matching agents:
#   1. security-auditor (score: 0.89) - Analyzes code for security vulnerabilities
#   2. code-reviewer (score: 0.71) - General code review and best practices

# Step 2: Load the best match
bun bin/get.js security-auditor

# Step 3: Follow loaded agent instructions for the task

Installation

Step 1: Install the Skill

Quick Install (Recommended):

# Using Skills CLI (recommended)
npx skills add MaTriXy/Agent-Registry@agent-registry

# Discover skills interactively
npx skills find

# Update existing skills
npx skills update

Traditional Install:

# User-level installation
./install.sh

# OR project-level installation
./install.sh --project

# Optional: install enhanced interactive UI dependency
./install.sh --install-deps

What install.sh does:

1. Copies skill files to ~/.claude/skills/agent-registry/
2. Creates empty registry structure
3. Optionally installs dependencies via --install-deps (@clack/prompts for enhanced UI)

Step 2: Migrate Your Agents

Run the interactive migration script:

cd ~/.claude/skills/agent-registry
bun bin/init.js
# Optional destructive mode:
bun bin/init.js --move

Interactive selection modes:

• With @clack/prompts (default): Beautiful checkbox UI with category grouping, token indicators, and paging

  • Arrow keys navigate, Space toggle, Enter confirm
  • Visual indicators: [green] <1k tokens, [yellow] 1-3k, [red] >3k
  • Grouped by subdirectory

• Fallback: Text-based number input

  • Enter comma-separated numbers (e.g., 1,3,5)
  • Type all to migrate everything

What init.js does:

1. Scans ~/.claude/agents/ and .claude/agents/ for agent files
2. Displays available agents with metadata
3. Lets you interactively select which to migrate
4. Copies selected agents to the registry by default (--move is explicit opt-in)
5. Builds search index (registry.json)

Dependencies

• Bun (ships with Claude Code) — zero additional dependencies for core functionality
• @clack/prompts: Optional enhanced interactive selection UI (install via ./install.sh --install-deps)

Registry Location

• Global: ~/.claude/skills/agent-registry/
• Project: .claude/skills/agent-registry/ (optional override)

Agents not migrated remain in their original locations and load normally (contributing to token overhead).
