## Skills

- [Use Fastmail safely with AI](https://revampkey.com/marketplace/fastmail/skills/essentials.md): A practical guide to using the Fastmail connector: confirm the account and access level, search efficiently, and get explicit approval before any change to mail, calendar, contacts or notes.
- [Brief your calendar week with AI, read-only](https://revampkey.com/marketplace/fastmail/skills/calendar-week-brief.md): Reads your Fastmail calendars for the coming week and returns a short briefing that flags overlapping events, invitations awaiting a reply and meetings that need preparation. It changes nothing on your calendar.
- [Clean up your Fastmail contacts](https://revampkey.com/marketplace/fastmail/skills/contact-cleanup.md): Audits your Fastmail contacts for duplicates, missing details and stale entries, then proposes a merge and edit list. It changes nothing until you approve each item.
- [Schedule meetings in Fastmail with AI](https://revampkey.com/marketplace/fastmail/skills/meeting-scheduling-assistant.md): Finds workable meeting times across your Fastmail calendars, drafts the event, and checks the calendar, time zone and sending address with you. It creates or answers nothing until you approve the exact version.
- [Triage your Fastmail inbox with AI](https://revampkey.com/marketplace/fastmail/skills/triage-inbox.md): Sorts your unread or recent Fastmail mail into act-now, reply-later, file and ignore buckets, based on what each message actually asks of you. It reads selectively, drafts nothing and changes nothing until you approve a batch.

### What is a Fastmail agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Fastmail skill describes one job, which Fastmail tools to use in which order, what to check first and when to stop and ask you.

### Do the Fastmail skills change anything on their own?

2 of the 5 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Fastmail.

### Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Fastmail; elsewhere you copy the folders into your project or skills directory.

### Do I need the Fastmail MCP server too?

Yes. The skills tell the agent how to do the work; the Fastmail MCP server gives it the tools to do it. The Fastmail MCP setup guide covers every client.
