@@ -10,7 +10,7 @@ The model-facing control surface for `ctx.tasks`: three kind-independent tools,
All three use generic ACP cards: `read` for output and list, `execute` for kill.
When a producer supplies `outputLimitBytes`, `task_output`, terminal `task_kill`, and completion notices cap the complete UTF-8 result after adding status or notice text. Reads retain the output tail and control suffix when they fit; a bounded completion notice instead reserves `background task <id>` and the `task_output` collection instruction before spending remaining bytes on its variable kind, label, status, and detail. A prepended pre-execute listener captures the caller-visible task before policy, and each task-control definition's final-content callback applies its producer cap to single-text denials, short-circuits, normalized tool or pipeline failures, replacements, and blocks; structured multi-block policy results retain their shape. An existing producer truncation marker is reused rather than duplicated. Producers that omit the field retain the existing unbounded control-surface behavior.
