The add-ons
Teach it once. Every agent inherits it.
A skill is a reusable set of instructions you install on any agent at boot. Upload a bundle, get an install URL, and pass it at startup.
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
- Runtime-injected by the agent
- 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 can discover and apply skills mid-session.
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.
Upload your own bundle, copy the install URL from the Skills tab, and pass it to an agent at boot. The agent decides what's relevant.
Upload your own bundle
Package your instructions, upload in the Skills tab, and receive an install URL to hand to any agent.
Installed at boot, applied by the runtime
Pass the install URL to an agent at boot. The runtime injects skill instructions when the task matches — no per-turn wiring needed.
Author in plain Markdown
Write your instructions in plain Markdown and upload — your bundles live in your private Skills library.
How you turn it on: Package your instructions, upload in the Skills tab, and get an install URL. Pass it to any agent at boot. Agents also discover and apply public skills automatically.
