Module subagent_cards 

The session’s sub-agent instances, folded as the frames arrive.

One card per Task/Agent dispatch, joined with the frames that ran under it. The identity is the wire’s own link: a dispatch is an assistant frame carrying the Task tool call, and every frame the instance produces names it in parent_tool_use_id.

Two entry points, one fold. subagent_cards drives CardTracker over a conversation that already exists (a read, a resumed page); the session task drives the same tracker one frame at a time and emits when the list moves, so a live session never re-walks its conversation to push a card.

Structs

Answer 🔒

What the rows answering one dispatch say about it.

CardTracker

The instances as frames arrive, one at a time.

ChildCall 🔒

One call an instance fired.

Instance 🔒

One instance while it is being folded.

Roster 🔒

What the CLI’s task roster says about one task, keyed by its task id.

Enums

Liveness 🔒

What a session’s own frames say about whether an instance is over.

Constants

TAIL_CAP

How many of an instance’s calls its card draws.

Functions

child_of 🔒

One call an instance fired, as it arrives: pending until its result lands, named by the shared call builder so a card’s tail and the chat’s rows resolve a title the same way.

content_is_hand_back 🔒

Whether a result’s content carries the CLI’s hand-back marker.

dispatch_name 🔒

What the dispatch called this instance. The description is the name the CLI’s roster and its own rows use; the type is what is left when the dispatch named none.

finished 🔒

Whether the rows answering a dispatch say the instance is over.

is_failure_status 🔒

Whether an ending’s word is a failure. killed and stopped are in: a cancel is not a clean finish.

is_terminal_status 🔒

Whether a wire status word says the task is over. The CLI’s vocabulary is free-form and forge does not classify all of it, so this names the endings: a status nobody has seen is not evidence that work stopped.
