Manage team communications by triaging Gmail inbox with Eisenhower prioritization and drafting replies, plus automating Slack channel management, message search, and AI categorization.
AI-powered email triage that reads your inbox, classifies each message by importance and urgency (Eisenhower matrix), decides whether you need to reply, and drafts responses in your voice. Use this skill whenever the user asks to triage their email, process their inbox, check what needs a response, draft email replies, prioritize messages, do an inbox review, or anything related to email workflow automation. Also trigger when the user says things like "what emails need my attention", "help me get to inbox zero", "process my unread mail", "draft replies", "what's urgent in my inbox", or "catch me up on email".
Slack channel management, message fetching, searching, and AI categorization. Use this skill when searching Slack channels, reading messages, creating channels, or categorizing message content. Triggers on Slack-related operations, channel search, message history, or internal communications analysis.

# Install the skills CLI, then add everything from the marketplace
npx skills add https://github.com/Casper-Studios/casper-marketplace --all -g
The --all flag is idempotent — it installs new skills and overwrites existing ones. The CLI handles cloning, diffing, and symlinking internally.
