Skills reference

What a Cadence assistant can do out of the box, plus how to extend it. This page is a catalog. The live inventory on a hatched assistant is assistant skills list. Mechanics: Skills and tools. Authoring: Your first skill.

Most service skills need a one-time OAuth or API-key connect. Sends, purchases, and host access ask first unless you write a trust rule.

Each skill, when used well, answers:

What it does (one sentence)
Setup (keys, OAuth, or none)
Permissions (sandbox vs host, send vs read)

Communication

Gmail: Archive, label, draft, send, unsubscribe, filters. OAuth. Sends need approval.
Email (Agent Mail): Give the assistant its own mailbox via a mail provider you configure (not an Aevum-hosted inbox).
Messaging: Read, search, send, and manage messages across connected platforms.
Phone and SMS: Twilio voice and SMS after you store Twilio credentials. Inbound voice can reject. A2P to US cells needs carrier registration when you leave trial.
Slack: Scan channels, summarize threads, send, reactions. User integration and Slack bot are different connects.
Contacts: People, channels, and who may talk to the assistant.
Notifications: Route alerts across the channels you have connected.

Calendar and work

Google Calendar: View the schedule, create events, check availability. OAuth.
Tasks: Reusable templates and a prioritized queue.
Schedule: One-shot and recurring jobs (cron, RRULE, or a fire-at time). See Scheduling.
Followups: Track outbound messages still waiting on a reply.
Playbooks: Trigger-action rules for inbound messages.
Start the Day: A briefing from weather, calendar, news, and tasks you have actually connected.
Document: Long-form drafts: posts, articles, reports.

Web, host, and automation

Browser: Navigate, click, type, extract, screenshot via assistant browser. See Features.
Host computer access: On Linux, host_file_* and host_bash after you grant host access. Not a silent full-disk grant on hatch.
Computer Use / Screen Watch: macOS GUI click, type, and OCR. Not the Linux 0.1 path. Linux uses host tools and Browser instead.
Watcher: Poll an external source and notify on change.
Subagent: Spawn background work that runs in parallel.
ACP: Delegate coding to an external agent over the Agent Client Protocol.
App Builder: Build an interactive web app from a description, in the conversation.

Media and services

Image Studio: Generate and edit images when an image model is configured.
Media processing: Ingest video, audio, and image files through a processing pipeline.
Transcribe: Audio and video to text with Whisper.
Weather: Current conditions and multi-day forecasts.
Amazon: Search and shop after you connect the account. Purchases need approval.
DoorDash: Order food or groceries after you connect. Purchases need approval.
ChatGPT import: Import conversation history from a ChatGPT export into this assistant.

System and setup

Skill management: Create, inspect, and delete custom skills in the workspace.
Skills catalog: Discover and install first-party and community skills (including skills.sh).
Cadence self-knowledge: Answer "can you do X?" from the CLI, these docs, and source. Not from guesswork.
LLM provider setup: Bring your own keys (Hive, xAI, or another OpenAI-compatible endpoint). Cadence does not bill model usage in 0.1.
OAuth / MCP / channel setup: Dedicated setup skills for Slack, Telegram, Twilio, GitHub, Linear, Notion, and MCP servers. "Is X connected?" has two answers: catalog vs live status. Use assistant oauth status and assistant channels list.
