Struct Binding 

pub struct Binding {

    pub session: Option<String>,
    pub profile: Option<String>,
    pub project: Option<String>,
    pub role: Option<String>,
    pub agent: Option<String>,
    pub team: Option<String>,
    pub mcp_url: Option<String>,
    pub session_token: Option<String>,
    pub session_id: Option<String>,
    pub epoch: Option<i64>,
    pub expires_at: Option<String>,
    pub closed_at: Option<String>,
    pub binding: Option<String>,
}

What the proxy of this conversation recorded: which profile, project and role it settled on. Advisory — a hook works without it, just with less.

Fields

session: Option<String>

profile: Option<String>

project: Option<String>

role: Option<String>

agent: Option<String>

team: Option<String>

mcp_url: Option<String>

Endpoint the proxy of this conversation is connected to.

session_token: Option<String>

The session credential. Present only while the window is open, and only ever read by context hook: never printed, logged or passed in argv.

session_id: Option<String>

epoch: Option<i64>

Epoch to send with it. A hook uses the proxy’s epoch rather than registering, which would bump it and fence the proxy it belongs to.

expires_at: Option<String>

closed_at: Option<String>

binding: Option<String>

Where the proxy got the conversation id this record is keyed by: explicit, claude-code, antigravity, request-meta (Codex’s _meta.threadId on the host’s own tool calls) or instance. Absent in records older than 0.7.7. The Codex wake adapter only accepts request-meta: the thread id must come from Codex, never from a guess.
