This is third-party code. Review the repository files before installing.

What it does

The repository collects independent skills in the Agent Skills format, each with its own scripts. The PostgreSQL, MySQL and MSSQL skills run read-only queries and block writes. The Google Workspace skills handle Gmail, Calendar, Docs, Sheets, Drive, Slides and Chat with their own OAuth. There are also skills for Atlassian, Azure DevOps, Outline, a Telegram bot with button approvals, ElevenLabs and Google TTS narration, Gemini image generation and Deep Research, and delegating tasks to Jules, Manus and Grok Build.

Who it is for. For developers and analysts who want to connect an agent to databases and work services without a separate MCP server.

Limitations

Most skills need their own keys and accounts: GEMINI_API_KEY, OUTLINE_API_KEY, ElevenLabs, Google Cloud, a Google Workspace account. Gemini Deep Research is billed per query. Database credentials are stored in plain connections.json. Gemini, ElevenLabs and Google APIs may be unavailable from Russia without a VPN, while the database and Telegram skills run locally.

How to disable. Run npx skills remove <skill name> or uninstall the ai-skills plugin via /plugin. For manual installs, delete the skill folder from the agent's skills directory.

Security check

• Stores database credentials and OAuth tokens
• The Gmail, Telegram and Jira skills can send messages and change data in external systems
