SkillsGate: Open Source Marketplace for AI Coding Agent Skills

SkillsGate is an open source marketplace for discovering, installing, and publishing skills for AI coding agents including Claude Code, Cursor, and Windsurf. The project has indexed over 45,000 skills from GitHub repositories, enriched them with LLM-generated metadata, and built vector embeddings for semantic search functionality.
Current Features
The tool currently offers:
- Semantic search that understands intent rather than just keywords. For example, searching "help me write better commit messages" returns relevant skills.
- One-command installation via
npx skillsgate add username/skill-namefor SkillsGate-hosted skills - Direct installation from any GitHub repository using
npx skillsgate add owner/repo - Publishing capabilities for your own skills through direct upload (GitHub repository sync is in development)
Development Roadmap
Features currently under development include:
- Private and organization-scoped skills for team usage
The source code is available at github.com/skillsgate/skillsgate.

Event Horizon VS Code Extension Adds File Locking and Plan Coordination for Multiple AI Agents
Event Horizon, a VS Code extension originally created for visualizing Claude Code, now includes file locking and plan coordination features to prevent multiple AI agents from overwriting each other's work on the same codebase. The tool supports Claude Code, OpenCode, and Copilot with one-click setup.

MCP Server Connects Claude to Agent-to-Agent Marketplace
A developer built an MCP server that exposes five tools and two resources, allowing Claude to search, invoke, and pay for capabilities from other AI agents in a marketplace. The server includes persistent storage in an agent vault and was largely implemented using Claude Code.

Zoku: A Tool That Automatically Detects Repeated Workflows in Claude Code
Zoku is a local tool that hooks into Claude Code's event system to record tool actions across sessions, identifies repeated workflow patterns, and then informs Claude about these patterns so it can proactively suggest or execute them. It requires no configuration, has no dependencies, and stores everything locally in ~/.zoku/.

Kelet: Automated Root Cause Analysis for AI Agents
Kelet is a service that automatically analyzes production AI agent failures by clustering traces and signals to identify root causes and suggest fixes. It integrates via Python/TypeScript SDKs or an installer skill and is currently free during beta.
