Constants

LARGE_PROMPT_THRESHOLD

Truncation threshold, matching the shell’s large-prompt limit.

Functions

format_interjection

Wrap interjection text as a synthetic user message with a mid-turn note. No deferral instruction: the model decides how to weigh it against in-flight work. Output is byte-identical to the shell’s historical format.

user_query

Wrap a user message in the canonical <user_query> envelope.
