Struct SpawnSpec

    pub cwd: PathBuf,
    pub task_id: String,
    pub command: Vec<String>,
    pub env: BTreeMap<String, String>,

}

Fields

cwd: PathBuf

task_id: String

command: Vec<String>

env: BTreeMap<String, String>

tools_token: String

The tools-mount token this client minted for the session being opened.

A session the client drives itself has no plugin to carry its obligations, so this token is what binds the onlyne mcp child back to this one session (docs/v2-CONTRACT.md §3b). It travels here and not inside env, because env is the agent process’s own environment: a capability the model can print is no capability, and the mount’s env belongs to the tool child alone.

prose: String

The role’s control-plane prose, as the slice welcome brought it.

A runtime with a system-prompt extension point is handed this through that point. An ACP session has none, so this is what the client writes into the workspace instruction file before the session opens (AGENTS.md §12).

focus: Option<bool>

placement: Option<PanePlacement>

rename: Option<String>
