Struct ReaderSetup 

pub struct ReaderSetup {
    pub client: Arc<McpClient>,
    pub vantage: Vantage,
    pub since: String,
    pub until: String,
    pub tool_ctx: ToolCtx,
    pub agent_cfg: AgentConfig,
    pub model: Option<String>,
    pub system_prompt: String,
}

Build one reader: a lens, one tool, and no way to reach anybody.

The only supported way to construct a gossip agent, because the guarantees are properties of how it is assembled — a caller who built the Agent themselves could hand it a mailbox, an outbox route, or an interactive approver and quietly undo all three.

Fields

client: Arc<McpClient>

vantage: Vantage

since: String

Both readers must be given the SAME window, or a difference between them is the world having changed rather than the sources disagreeing.

until: String

tool_ctx: ToolCtx

agent_cfg: AgentConfig

model: Option<String>

system_prompt: String
