The add-ons
Agent Skills
A skill is a reusable set of instructions and context that attaches to an agent when it is relevant to the task at hand. Agents discover and install public skills on their own. Upload your own bundles, get an install URL, and hand it to any agent you run.
Skills, tools, and connectors
Instructions and context
A skill shapes how the agent thinks about a domain. It is a named Markdown document — instructions, heuristics, examples — that the agent applies when the task calls for it.
- Domain expertise
- Reusable instructions
- Auto-discovered by agents
- Authored in Markdown
Functions the agent can call
A tool gives the agent an action it can execute: web search, image generation, transcription, browser control. Tools are capabilities, not instructions.
- Web search
- Image generation
- Transcription
- Browser control
Authorized app integrations
A connector is an OAuth link to a third-party app — Gmail, Notion, GitHub. Connectors let agents read and write to those apps; skills tell agents how to use the output.
- Gmail, Notion, Slack
- Managed OAuth
- Read and write access
- 2,000+ integrations
How skills attach at runtime
Agents discover and apply skills automatically.
When an agent starts a task, it evaluates the available skills against the current task description and context. Skills whose descriptions match what the task requires are injected into the agent's context — their instructions become part of how the agent reasons about the problem.
You do not configure which skill goes to which agent. Upload your own bundle, copy the install URL from the Skills tab, and pass it to an agent at boot. The agent decides what is relevant when it runs.
Upload your own bundle
Package a SKILL.md with your instructions into a .zip or .tar.gz, upload it in the Skills tab, and receive an install URL to hand to any agent.
Agents install on their own
No per-agent wiring needed. When a task matches a skill, the agent pulls it in automatically and applies its instructions.
Author in plain Markdown
Write a SKILL.md with a name, description, and body. Package and upload — your bundles live in your private Skills library.
How you turn it on: write a SKILL.md, package it as a .zip or .tar.gz, upload it in the Skills tab, and copy the install URL. Pass the URL to any agent at boot. Agents also discover and apply public skills automatically when they run.
