⚡ Updated for Opus 4.5, Sonnet 4.5 & Haiku 4.5 — Three-tier model strategy for optimal performance

🎯 Agent Skills Enabled — 107 specialized skills extend Claude's capabilities across plugins with progressive disclosure

A comprehensive production-ready system combining 99 specialized AI agents, 15 multi-agent workflow orchestrators, 107 agent skills, and 71 development tools organized into 67 focused, single-purpose plugins for Claude Code.

This unified repository provides everything needed for intelligent automation and multi-agent orchestration across modern software development:

• 67 Focused Plugins - Granular, single-purpose plugins optimized for minimal token usage and composability
• 99 Specialized Agents - Domain experts with deep knowledge across architecture, languages, infrastructure, quality, data/AI, documentation, business operations, and SEO
• 107 Agent Skills - Modular knowledge packages with progressive disclosure for specialized expertise
• 15 Workflow Orchestrators - Multi-agent coordination systems for complex operations like full-stack development, security hardening, ML pipelines, and incident response
• 71 Development Tools - Optimized utilities including project scaffolding, security scanning, test automation, and infrastructure setup

• Granular Plugin Architecture: 67 focused plugins optimized for minimal token usage
• Comprehensive Tooling: 71 development tools including test generation, scaffolding, and security scanning
• 100% Agent Coverage: All plugins include specialized agents
• Agent Skills: 107 specialized skills following for progressive disclosure and token efficiency
• Clear Organization: 23 categories with 1-6 plugins each for easy discovery
• Efficient Design: Average 3.4 components per plugin (follows Anthropic's 2-8 pattern)

Each plugin is completely isolated with its own agents, commands, and skills:

• Install only what you need - Each plugin loads only its specific agents, commands, and skills
• Minimal token usage - No unnecessary resources loaded into context
• Mix and match - Compose multiple plugins for complex workflows
• Clear boundaries - Each plugin has a single, focused purpose
• Progressive disclosure - Skills load knowledge only when activated

Example: Installing python-development loads 3 Python agents, 1 scaffolding tool, and makes 5 skills available (~300 tokens), not the entire marketplace.

Add this marketplace to Claude Code:

/plugin marketplace add wshobson/agents

This makes all 67 plugins available for installation, but does not load any agents or tools into your context.

Browse available plugins:

/plugin

Install the plugins you need:

# Essential development plugins
/plugin install python-development          # Python with 5 specialized skills
/plugin install javascript-typescript       # JS/TS with 4 specialized skills
/plugin install backend-development         # Backend APIs with 3 architecture skills

# Infrastructure & operations
/plugin install kubernetes-operations       # K8s with 4 deployment skills
/plugin install cloud-infrastructure        # AWS/Azure/GCP with 4 cloud skills

# Security & quality
/plugin install security-scanning           # SAST with security skill
/plugin install code-review-ai             # AI-powered code review

# Full-stack orchestration
/plugin install full-stack-orchestration   # Multi-agent workflows

Each installed plugin loads only its specific agents, commands, and skills into Claude's context.

You install plugins, which bundle agents:

# ❌ Wrong - can't install agents directly
/plugin install typescript-pro

# ✅ Right - install the plugin
/plugin install javascript-typescript@claude-code-workflows

"Plugin not found" → Use plugin names, not agent names. Add @claude-code-workflows suffix.

Plugins not loading → Clear cache and reinstall:

rm -rf ~/.claude/plugins/cache/claude-code-workflows && rm ~/.claude/plugins/installed_plugins.json

Strategic model assignment for optimal performance and cost:

Why Opus 4.5 for Critical Agents?

• 80.9% on SWE-bench (industry-leading)
• 65% fewer tokens for complex tasks
• Best for architecture decisions and security audits

Tier 2 Flexibility (inherit): Agents marked inherit use your session's default model, letting you balance cost and capability:

• Set via claude --model opus or claude --model sonnet when starting a session
• Falls back to Sonnet 4.5 if no default specified
• Perfect for frontend/mobile developers who want cost control
• AI/ML engineers can choose Opus for complex model work

Cost Considerations:

• Opus 4.5: $5/$25 per million input/output tokens - Premium for critical work
• Sonnet 4.5: $3/$15 per million tokens - Balanced performance/cost
• Haiku 4.5: $1/$5 per million tokens - Fast, cost-effective operations
• Opus's 65% token reduction on complex tasks often offsets higher rate
• Use inherit tier to control costs for high-volume use cases

Orchestration patterns combine models for efficiency:

Opus (architecture) → Sonnet (development) → Haiku (deployment)
