The email-as-queue workflow — extract structured data from emails, act on it, track thread state, and delete emails when topics complete. Email is transient; extracted data is persistent.

Manual OAuth2 token exchange for Gmail on headless servers. Bypass gmail-mcp-multiauth browser requirement. Generate auth URLs, exchange codes, manage multi-account credentials with auto-refresh.

Multi-account Gmail management via himalaya CLI. Three accounts (aceengineer, achantav, skestates) with distinct triage rules, contact DBs, and tone profiles. Foundation skill for email automation.

Class-level Gmail and email operations: multi-account setup, OAuth, triage, extraction, archiving, attachments, unsubscribe, and touchbase workflows.

Outbound email actions — periodic relationship touchbase messages and batch unsubscribe from newsletters/marketing. Combines gmail-touchbase + gmail-unsubscribe into one skill.

Daily multi-account Gmail inbox triage — scan unread, classify by urgency, cross-reference contacts, generate actionable digest. Supports ace/personal/skestates accounts.
