From f122b66bb4986a1377051cb93e2d350ab68b3bcc Mon Sep 17 00:00:00 2001 From: Haider Date: Mon, 21 Sep 2026 21:26:26 +0530 Subject: [PATCH 1/5] fix(run): a non-interactive turn must end with text, even after a tool failure MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In headless use nobody can approve a permission, so a `bash` call is auto-rejected; the rejection goes back to the model as a tool error, and the model frequently stops there without a word. The process printed nothing and exited 0, although it had already read enough to answer — nine of nine such turns in the pilot triage, and the same shape after any failed tool with `--yolo` (#1334). `run` now tracks whether the assistant produced any text and the last tool failure. When the turn ends silent, it sends one synthetic reply turn naming the failed tool ("do not retry that tool; answer with what you have; say what could not be completed and why"), through the same synthetic-turn path the idle-done challenge uses. If the model still says nothing, a synthesised line says what happened, goes to stdout (and `--output`), and the run exits 1 so a script can tell "no answer" from "answered". A turn that answered normally is untouched. The flag is set before the JSON-mode `emit`, which `continue`s past the rest of the text handler — the first cut missed that and made every `--format json` run look silent. Tests: subprocess runs with the scripted LLM — rejected `bash` + empty reply → follow-up answer printed, exit 0; silent again → synthesised line, exit 1; a normal answer sends no follow-up. Unit tests for the directive text. The reply path was disabled once to confirm the tests fail.

A subscribe or send failure on the reply turn (the challenge and continuation turns had the same gap) was accounted as the run's fatal error but never printed or emitted: the caller saw "asking for one" and an exit code with no connection/SSE error. Both failure paths now go through the normal error output — `error` for the trace, the JSON `error` event, `UI.error` otherwise — before returning. Test title aligned with the directive no longer carrying the tool's error.
