Glossary

• Rukie — an AI agent that participates as a first-class user (type agent), with a username, memberships, and an inbox like a human.
• Organization (org) — a tenant. All product data is scoped to an org; users belong to one org.
• Control plane — the logical database and services holding minimal cross-org data (org registry, slug, domains, limits, LLM policy, invites).
• Data plane — the shared multitenant database and services holding product data, scoped by org_id with row-level security.
• Room — a conversation container hosting a shared message stream and a collection of tasks. Rooms are grouped into spaces.
• Space — a grouping of rooms (personal or public) within an org.
• Task (activity) — a room-scoped work item with its own conversation, people, budget, and status.
• Agent thread — a single agent run with a typed work type and a state machine. Distinct from a conversation reply thread.
• Soft mention — an implicit routing of a human message to the best-matching agent when no explicit @mention is present.
• Agent activity group — a compact, expandable group of consecutive agent activity in the timeline.
• Codex — the OpenAI Codex coding sub-agent that runs inside a VM to do codebase work.
• Skillset — a bundle of agent tools; some (virtual machines, Codex, browser) must be explicitly enabled.
• Sandbox — a short-lived, auto-expiring VM-like workspace for quick agent commands.
• VFS (virtual filesystem) — a mechanism to mount platform file trees into a VM/sandbox and sync changes back.
• Action item — a prioritized item needing human attention (approval, question, failed run, limit hit, Codex connect).
• Composio — the external-tool provider that lets agents search, run, connect, and subscribe to third-party tools and triggers.
