plessas-lab
A lab marketplace of experimental Claude Code plugins. Tools for Apple Notes, Gmail, image generation, YouTube content management, and a Microsoft Teams chat monitor.
Companion to plessas-marketplace (production-grade workplace plugins). Plugins here are flagged "lab" because they require external API setup (Google OAuth, Gemini key, etc.) or are experimental in scope.
Available Plugins
| Plugin | Version | Category | Platform | Description |
|---|
| manage-apple-notes | v1.0 | Productivity | macOS only | CRUD operations for Apple Notes — persistent storage of thoughts, data, and information across sessions |
| manage-gmail | v1.0 | Communications | All platforms | Access and process Gmail messages via the Gmail API — read, search, list, send, reply, and forward emails with OAuth 2.0 |
| manage-nano-banana | v1.0 | Creative | All platforms | Generate and edit images, diagrams, infographics, and visualizations using Google's Nano Banana API (Gemini Image Generation) |
| manage-youtube | v1.0 | Media | All platforms | Search, discover, and manage YouTube content — channels, videos, transcripts, favorites, playlists via TypeScript CLI tools |
| chat-watch | v0.1 (experimental) | Communications | All platforms | Polls one or more Microsoft Teams chats and posts [Claude]-prefixed replies when an LLM gate decides adding context is genuinely useful |
Commands
| Command | Plugin | Description |
|---|
/apple-notes | manage-apple-notes | Access and manage Apple Notes (list, create, read, delete) |
/gmail | manage-gmail | Access and process Gmail messages (list, search, read, send, reply, forward, draft) |
/nano-banana | manage-nano-banana | Generate or edit images, create diagrams and visualizations |
/create-nbg-infographic | manage-nano-banana | Create an NBG-themed infographic using Nano Banana |
/youtube | manage-youtube | Search YouTube, get channel info, retrieve videos and transcripts |
chat-watch does not register a slash command — it ships a Python CLI (monitor.py) intended to run as a long-lived process (manually or via launchd). See plugins/chat-watch/README.md for setup.
