Fusengine Claude Code Plugins

A plugin ecosystem that turns Claude Code into a supervised, multi-agent development environment. Expert agents write code, hooks enforce quality in real-time, skills inject framework-specific knowledge, and intelligent cartography auto-maps plugins and projects — so Claude never guesses, never duplicates, and always follows your architecture.

Scripted demo — a faithful reconstruction of the real hook → agent → sniper cycle. Regenerate with vhs docs/demo/hook-sniper.tape.

What It Does

Without plugins: Claude Code writes code based on its training data. It can hallucinate APIs, duplicate existing code, ignore your project structure, and produce inconsistent quality.

With Fusengine plugins:

• Expert agents detect your project type (Next.js, Laravel, React, Astro, Swift...) and load framework-specific documentation via MCP servers before writing a single line
• 60+ hook checks intercept Write/Edit/Bash and agent/session lifecycle events to enforce file-size limits (<100 lines), block code duplication (DRY), require SOLID reference reads, gate documentation lookup, and block destructive shell commands
• 196 skills inject copy-paste-ready templates, architecture patterns, and best practices directly into agent context — no hallucination needed
• APEX workflow structures every task through Analyze → Plan → Execute (TDD) → Review → Validate — preventing the "just write code and hope" approach
• Sniper agent — a 7-phase post-edit quality check (explore → research → grep usages → lint → fix → zero errors) the APEX workflow invokes after every modification

Quick Install

# Add marketplace
/plugin marketplace add fusengine/agents

# Install all plugins
/plugin install fuse-ai-pilot fuse-commit-pro fuse-laravel fuse-nextjs fuse-react fuse-astro fuse-swift-apple-expert fuse-solid fuse-tailwindcss fuse-design fuse-prompt-engineer fuse-shadcn-ui fuse-security fuse-changelog fuse-lessons fuse-tanstack-start fuse-typescript fuse-php fuse-rust fuse-go

# Setup (hooks + API keys + MCP servers)
~/.claude/plugins/marketplaces/fusengine-plugins/setup.sh        # macOS / Linux
~\.claude\plugins\marketplaces\fusengine-plugins\setup.ps1       # Windows

Statusline (optional):

bun --cwd ~/.claude/plugins/marketplaces/fusengine-plugins/plugins/core-guards/statusline run config

How It Works

User prompt → Hook detects project type → Expert agent activated
            → Hook loads SOLID references → Agent reads docs via MCP
            → Hook blocks if DRY violation → Agent writes code
            → Hook checks file size → Agent runs Sniper validation
            → Commit gate blocks on lint/type errors → Commit with version bump

Every step is intercepted. Claude cannot skip research, cannot duplicate code, cannot exceed file size limits, and cannot commit with lint or type errors.

Plugins

Development — Framework Expert Agents

Each plugin provides an expert agent that auto-activates when it detects the framework in your project. The agent has access to official documentation via MCP servers and follows SOLID principles enforced by hooks.
