This plugin provides idiomatic development assistance across eight major programming languages and frameworks: C#/.NET, Go, Java/Kotlin, Python, Rust, TypeScript, shell, and web technologies. It bundles one AI agent with eight skills to help developers follow language-specific best practices and conventions.

This toolkit provides seven specialized skills and a guided workflow command for building Claude Code plugins, covering hooks, MCP integration, plugin structure, settings, commands, agents, and skills. The /plugin-dev:create-plugin command guides users through an 8-phase process from discovery to documentation, with best practices, examples, and validation utilities included.

This skill guides TYPO3 extension developers through systematically upgrading extensions to newer LTS versions by diagnosing deprecated APIs, automating PHP and non-PHP code migrations, and providing version-specific guidance across TYPO3 v7–v14. It integrates with tools like Rector, Fractor, PHPStan, and the Extension Scanner to streamline the upgrade workflow.

This plugin provides a spec-driven development workflow system with four specialized agents that guide feature development through structured phases: Requirements (business analyst), Design (software architect), Tasks (development lead), and Implementation (strict task executor). The workflow enforces sequential execution with approval gates, zero-improvisation during coding, and produces comprehensive specification documents at each phase.

This plugin provides browser-based testing, validation, screenshots, recordings, and quick automation capabilities through an agent and supporting skills. It requires no external API keys or third-party services.

This plugin provides a rigorous performance investigation workflow that establishes baselines, runs controlled sequential benchmarks, and performs profiling to identify hotspots. It consolidates findings into evidence-backed recommendations with structured logging and version-specific baselines.

This plugin provides a code-reviewer agent that performs systematic reviews against a base branch by analyzing diffs for critical issues and quality. It includes two skill strategies: disposable subagents for quick one-shot reviews and persistent team members for iterative follow-up questions.

spec-flow provides a lightweight spec loop that guides you through planning a slice, executing a task, and then checkpointing progress or closing out work. It consists of two agents and one skill to streamline iterative development cycles.

This plugin provides 3 agents and 7 skills for research, documentation lookup, utility routing, and skill authoring, along with instruction review and agent configuration auditing capabilities. It enables developers to audit reasoning processes and review agent configurations without requiring external API keys or services.

This plugin provides an infrastructure operations agent for managing Kubernetes, Terraform, Helm, GitHub Actions, and cloud platforms like AWS and GCP. It bundles capabilities for common DevOps and infrastructure automation tasks.

This TYPO3 extension testing skill generates unit, functional, and E2E tests automatically using Claude Code agents, with support for Playwright browser automation, accessibility testing via axe-core, and CI/CD integration templates. It provides infrastructure setup, fixture management, and quality tooling integration (PHPStan, Rector, php-cs-fixer) following TYPO3 best practices.
