Enhances Claude Code with battle-tested skills, commands, agents, and hooks for TDD, code review, security scanning, multi-agent orchestration, and language-specific best practices across TypeScript, Python, Go, Rust, Kotlin, Java, C++, and more.
npx claudepluginhub tpavanipradeep/everything-claude-codeStart a managed autonomous loop pattern with safety defaults.
Inspect active loop state, progress, and failure signals.
Recommend the best model tier for the current task by complexity and budget.
Backend-focused workflow (Research → Ideation → Plan → Execute → Optimize → Review), Codex-led.
Multi-model collaborative execution - Get prototype from plan → Claude refactors and implements → Multi-model audit and delivery.
Software architecture specialist for system design, scalability, and technical decision-making. Use PROACTIVELY when planning new features, refactoring large systems, or making architectural decisions.
Build and TypeScript error resolution specialist. Use PROACTIVELY when build fails or type errors occur. Fixes build/type errors only with minimal diffs, no architectural edits. Focuses on getting the build green quickly.
Personal communication chief of staff that triages email, Slack, LINE, and Messenger. Classifies messages into 4 tiers (skip/info_only/meeting_info/action_required), generates draft replies, and enforces post-send follow-through via hooks. Use when managing multi-channel communication workflows.
Expert code review specialist. Proactively reviews code for quality, security, and maintainability. Use immediately after writing or modifying code. MUST BE USED for all code changes.
C++ build, CMake, and compilation error resolution specialist. Fixes build errors, linker issues, and template errors with minimal changes. Use when C++ builds fail.
Design and optimize AI agent action spaces, tool definitions, and observation formatting for higher completion rates.
Operate as an agentic engineer using eval-first execution, decomposition, and cost-aware model routing.
Engineering operating model for teams where AI agents generate a large share of implementation output.
Regression testing strategies for AI-assisted development. Sandbox-mode API testing without database dependencies, automated bug-check workflows, and patterns to catch AI blind spots where the same model writes and reviews code.
Clean Architecture patterns for Android and Kotlin Multiplatform projects — module structure, dependency rules, UseCases, Repositories, and data layer patterns.
Matches all tools
Hooks run on every tool call, not just specific ones
Executes bash commands

The performance optimization system for AI agent harnesses. From an Anthropic hackathon winner.
Not just configs. A complete system: skills, instincts, memory optimization, continuous learning, security scanning, and research-first development. Production-ready agents, hooks, commands, rules, and MCP configurations evolved over 10+ months of intensive daily use building real products.
Works across Claude Code, Codex, Cowork, and other AI agent harnesses.
This repo is the raw code only. The guides explain everything.
