Installation

bash

# Via marketplace
/plugin install developer-toolbox

# Or local development
/plugin install ./skills/developer-toolbox

After installation, restart Claude Code to load the agents.

Usage Examples

Commit Helper

"Help me write a commit message for these staged changes"

Build Verifier

"My changes aren't appearing in production, verify the build output"

Code Reviewer

"Review this authentication code for security vulnerabilities"

Debugger

"I'm getting TypeError: Cannot read property 'map' of undefined"

Test Runner

"Use TDD to implement this user validation function"

Orchestrator

"Coordinate a refactor of the authentication system across 5 services"

Documentation Expert

"Create comprehensive API documentation for this REST endpoint"

Agent Design Philosophy

All agents follow the "MUST BE USED when" pattern for reliable auto-discovery:

yaml

description: |
  [Role] specialist. MUST BE USED when: [trigger 1], [trigger 2], [trigger 3].
  Use PROACTIVELY for [broad task category].

  Keywords: keyword1, keyword2, error-message-fragment

This ensures Claude Code discovers and proposes the right agent automatically based on user requests.

Agent-First Thinking Rule

The included

agent-first-thinking.md

rule encourages using agents by default:

The Inversion:

Wrong: "I'll do this manually unless it's big enough for agents"
Right: "I'll use agents unless there's a reason not to"

Triggers:

If about to...	Use instead...
grep/glob 3+ times	Explore agent
Read 5+ files	Explore agent
Same edit across files	Parallel agents
Audit multiple items	Parallel swarm

Customization

Each agent can be extended by editing its markdown file after installation:
