feat(agent): add runSubagent primitive for subagent spawning#23
Merged
Conversation
Adds a reusable runSubagent() function to the agent SDK that creates a fresh-context child Agent with model override, optional Budget (maxTurns/maxTokens/timeoutMs — all uncapped by default), signal forwarding, and a separate onEvent event stream. Returns SubagentResult with final text (for parent), full transcript messages (for caller persistence), and accumulated usage. The parent agent only sees the final text — the full transcript is isolated and available for the caller to persist to a child session. Background mode and task resumption are deferred to the app layer; permissions stay in the code layer.

Adds a reusable
unSubagent() function to the agent SDK that creates a fresh-context child Agent with:
The parent agent only sees
esult.text via the tool result. The full transcript (
esult.messages) is available for the caller to persist — it's isolated from the parent's context.
Layer 1 only (SDK). App-layer persistence (child sessions), background mode, and task resumption deferred.
