How Orbit agents use tools

6 ordered steps, from Apollo to Token budget.

Orbit-internal conceptsAI agents and harnessesConcepts and methodology

  1. Step 1: Apollo

    Apollo starts the path because it is Orbit's concrete bridge between user intent, project context, and executable agent work.

  2. Step 2: MCP (Model Context Protocol)

    MCP shows the protocol boundary where Orbit-connected services become callable tools for an agent.

  3. Step 3: Tool use

    Tool use is the visible behavior MCP enables, turning the agent from a text generator into a system that can inspect and act.

  4. Step 4: Function calling

    Function calling explains the structured request shape behind many tool interactions, so learners can distinguish protocol from invocation.

  5. Step 5: Agentic loop

    After individual calls, the agentic loop shows how observation, decision, action, and revision repeat during real work.

  6. Step 6: Token budget

    Token budget closes the path by showing the resource pressure that can end or distort long-running agent work.
