Struct WorkerSpawnReply 

pub struct WorkerSpawnReply {
    pub session_id: String,
    pub tag: String,
    pub mcp_families: Option<Vec<String>>,
    pub rate_limited_account: Option<String>,
    pub durability_warning: Option<String>,
    pub worktree: Option<String>,
    pub session_choice: SessionChoice,
}

Synchronous return from Command::SpawnWorker - the session_id that the new worker was issued and the tag value applied. Threaded back to the calling agents__spawn Tool impl via the oneshot receiver so the LLM sees {session_id, tag} in the tool result.

Fields

session_id: String

tag: String

mcp_families: Option<Vec<String>>

The worker’s stored MCP-family selection, canonicalised; None means every family. The spawn tool echoes it so the lead sees exactly which families this worker got.

rate_limited_account: Option<String>

Set to the account name when the walk had to take an account that is saturated or bailed, because no other account in the pin declares the project’s model. The spawn tool surfaces it as a notice, so the lead sees at spawn that the worker may hit a 429 right away instead of only finding out when it stalls.

durability_warning: Option<String>

Set when persisting the worker’s durable row failed (the store couldn’t open, or the write errored). The worker still spawns, but it won’t survive a forge restart. The spawn tool surfaces it as a warning so the lead knows the “durable” promise didn’t hold for this one. Mirrors worktree_cleanup_warning on despawn.

worktree: Option<String>

Where the worker landed: its worktree, or None when the project is not a git repo and the worker runs in the project root. Set by the spawn handler, which is the only place that knows both.

session_choice: SessionChoice

Which session the spawn landed on. The handler states what its own arguments say; the MCP facade restates it with the resolution it made, which is the only place a resume_session fallback is known.
