claude-code-plugins-plus-skills and claude-plugins
The first is a comprehensive plugin marketplace and package manager designed to supply a broad ecosystem of capabilities, while the second is a specialized workflow orchestration system that could consume plugins from such a marketplace to implement its plan-first SDLC methodology—making them complements rather than direct competitors.
About claude-code-plugins-plus-skills
jeremylongshore/claude-code-plugins-plus-skills
340 plugins + 1367 agent skills for Claude Code. Open-source marketplace with CCPI package manager, interactive tutorials, and production orchestration patterns.
Plugins activate through frontmatter-based trigger phrases in markdown SKILL.md files, allowing Claude Code to automatically invoke relevant tasks without explicit slash commands. The marketplace supports three plugin types—AI instruction plugins (markdown-only), MCP Server plugins (Node.js processes via Model Context Protocol), and SaaS skill packs for platforms like Deepgram and Linear—managed through the CCPI CLI or Claude's native `/plugin` commands. Includes production orchestration patterns and learning labs documenting multi-agent workflow architecture with empirical validation guides.
About claude-plugins
closedloop-ai/claude-plugins
Open-source Claude Code plugins for multi-agent software delivery. Plan-first SDLC workflow, code review, LLM quality judges, and self-learning — grounded in your codebase. Bootstrap, Plan, & Ship.
Implements a multi-agent orchestration framework atop Claude Code via six specialized plugins (bootstrap, code generation, code-review, quality judges, platform guidance, and self-learning) that gate workflow phases until correctness criteria are met. Uses codebase-grounded execution with adaptive feedback loops to reduce hallucinations and cost—benchmarks show performance parity with Claude Opus 4.6 at 50% expense. Designed for Claude Code integration; requires Python 3.11+ and ships with artifact-bound phased gates, multi-repository support, and organizational pattern capture for knowledge reuse across teams.
