The developer-kit-tools plugin provides delegation skills for external AI coding assistants and integration with third-party services through the Model Context Protocol (MCP). It enables Claude Code to leverage specialized tools for tasks that benefit from different models, large-context analysis, or dedicated service integrations.

Skills

Skill	Purpose	Triggers
`gemini`	Delegate tasks to Google Gemini CLI for large-context analysis and complex reasoning	"use gemini", "delegate to gemini", "gemini 3 flash/pro"
`copilot-cli`	Delegate tasks to GitHub Copilot CLI with multi-model support (Claude, GPT, Gemini)	"ask copilot", "delegate to copilot", "use copilot with sonnet/gpt"
`codex`	Delegate tasks to OpenAI Codex CLI for advanced code generation and analysis	"use codex", "codex exec", "codex review", "gpt-5.3-codex"
`qwen-coder`	Delegate tasks to Qwen Coder CLI for coding assistance using Qwen2.5-Coder and QwQ models	"use qwen", "delegate to qwen", "second opinion from qwen"
`notebooklm`	Integrate with Google NotebookLM for RAG, research notebooks, and AI-synthesized artifacts	"notebooklm", "nlm", "query notebook", "research notebook"
`sonarqube-mcp`	Integrate with SonarQube/SonarCloud for quality gates, issue discovery, and code analysis	"sonarqube", "quality gate", "sonar issues", "check sonar"

Quick Start

CLI Delegation Skills (gemini, copilot-cli, codex, qwen-coder)

# Verify the CLI is installed
gemini --version
copilot --version
codex --version
qwen --version

# Basic delegation pattern
gemini -p "Analyze this codebase architecture"
copilot -p "Refactor this service" --model gpt-5.2 --allow-all-tools
codex exec "Review this code for security issues"
qwen -p "Generate unit tests for this module"

MCP Integration Skills (notebooklm, sonarqube-mcp)

# NotebookLM - install and authenticate
uv tool install notebooklm-mcp-cli
nlm login

# SonarQube - set environment variables
export SONARQUBE_TOKEN="squ_your_token"
export SONARQUBE_URL="https://sonarqube.mycompany.com"
# or for SonarCloud:
export SONARQUBE_ORG="your-org-key"

When to Use Each Skill

Choose by Task Type

Task	Recommended Skill
Large codebase analysis (>100 files)	`gemini` (gemini-3-pro with 1M token context)
Quick prototyping and iterations	`gemini` (gemini-3-flash) or `qwen-coder`
Multi-model comparison on same task	`copilot-cli` (supports Claude, GPT, Gemini)
Advanced code generation and architectural design	`codex` (gpt-5.3-codex)
Code review with specialized review command	`codex` (`codex review`)
Second opinion or alternative reasoning	`qwen-coder` (QwQ deep reasoning)
Querying RAG knowledge bases	`notebooklm`
Generating podcasts/reports from documentation	`notebooklm`
Pre-commit/pre-push code quality checks	`sonarqube-mcp`
Quality gate verification before merge	`sonarqube-mcp`

Choose by Model Preference

Model Family	Skill
Google Gemini	`gemini` (gemini-3-flash, gemini-3-pro)
Anthropic Claude	`copilot-cli` (claude-sonnet-4.6, claude-opus-4.6, claude-haiku-4.5)
OpenAI GPT	`copilot-cli` (gpt-5.2) or `codex` (gpt-5.3-codex)
OpenAI o-series	`codex` (o3, o4-mini)
Alibaba Qwen	`qwen-coder` (qwen2.5-coder, qwq)

MCP Servers
