Grant model

How granting works

A skill is a permission you hand to an agent — not a silent preload.

1Pick it in SkillsAll 24 built-in skills live in one list. App Builder is there on day one — nothing to install.
2Grant it per agentA skill is a permission, not a preload. Each agent only carries the skills you've granted it, and you can take one back any time.
3It reaches only what's declaredThis one declares no access at all — the ledger below is the receipt.

Skill CreatorDesign, structure, and package a new OpenAlly skill (skill.toml + SKILL.md).

Agent AdminBuild and run your own team of sub-agents — create a focused agent for a recurring job, give it a persona and an FAQ, grant it skills and business access, test it, and clean it up.

App AutomationsBuild and run reusable app automations — your AI opens an app and taps, types, and scrolls through a flow for you (post to LinkedIn, search & play on YouTube, summarise Instagram activity, book an Uber up to payment, and more). Give it a topic and it writes the post — you pick from a few drafts before it publishes. Describe the flow once and your AI walks it on the real screen to learn the steps, then replays them fast and deterministically; it self-heals a step if the app changes, and hands off to you at logins and payments. Manage them from any chat. Schedulable. On-device, with your confirmation.

App GuideKnows OpenAlly inside-out — how to do anything in the app, the skills system, providers, Aster, privacy, support, and how to follow OpenAlly for feature updates. In in-app chat it can drop tappable buttons that open the right screen; in a messaging channel it gives written step-by-step directions.
