context

Context-window management (enabled by default; disabled #true to turn it off). One shared input-token budget drives trimming, the overflow guard and compaction:

context {
    reserved 20000                  // tokens kept for the model's reply; input budget = context_length − reserved
    keep-recent-tokens 20000        // tokens kept verbatim as the "tail" when older messages are trimmed
    tool-output-max-chars 16000     // cap on tool output sent to the model (truncated with a read hint); 0 disables
    tool-output-max-bytes 50000     // byte cap applied on top of the char cap; 0 disables
    fallback-context-length 128000  // used when the model catalog has no context length
}
