Skill
A skill is an installable extension that gives Theo a new behavior — a domain prompt, custom tools, allowed base tools, and an optional trigger (manual, event, schedule, or keyword).
In depth
Skills extend Theo without modifying the core. Each skill ships with a system prompt extension, custom tool definitions, required base tools, and a trigger type. Install from the Skill Store or author your own; user-installed skills run with credit guards and a separate autonomous daily cap.
Skills can power chat, scheduled background actions (via the heartbeat), event-driven hooks, and multi-step workflows.
Examples
- Content Calendar Builder skill
- Daily Standup Summarizer skill

E.V.I. (Executable Visual Intelligence)
E.V.I. (Executable Visual Intelligence) is the OpenCharts pipeline runtime — turn any flowchart into a live AI workflow where Theo executes each node in real time, calls APIs, and produces real deliverables.
Hook
A hook is an event-driven trigger that runs Theo automatically when something happens — a project is created, a share is accepted, a task goes overdue, a forum reply lands.
Workflow
A workflow is a multi-step automation — tool calls, AI transforms, conditions, delays, and notifications wired together with branching logic and credit checkpoints.
Heartbeat
Heartbeat is Theo’s background loop that periodically evaluates your installed scheduled skills and workflows — checking their schedule, your quiet hours, and credit availability before running.
Autonomous Daily Cap
The autonomous daily cap is a separate per-day credit budget for background actions — heartbeats, hooks, and workflows — so they can never drain your interactive credit balance.
