From a6a02d4ed03dbdac093268511940c7a3498ab71e Mon Sep 17 00:00:00 2001 From: defangdevs Date: Tue, 1 Sep 2026 01:09:49 +0000 Subject: [PATCH 1/3] watchdog: pick up assignments that never became a PR MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An assignment already starts an agent: the standing watch's `assigned` clause fires, webhook-spawn.sh starts a hook-* session, and that session's prompt says an assignment asks for the WORK, not a triage comment. That path is EDGE-triggered and fires exactly once. The session it starts can be refused by the hook-* ceiling, killed by a Spot interruption, stopped by hand, or simply answer the issue with a comment and call itself finished — and nothing ever looks again. The assignment stays open with no PR behind it, and the only thing that notices is a human re-reading the issue list days later. Add the level-triggered half. Every watchdog.interval seconds the supervisor runs a sweep that asks, for every issue assigned to this box's GitHub identity, whether any work is in flight — an open PR referencing it, or a live session claiming it — and starts one wd-- session for each that has none.

That is \ +why you exist -- the box's watchdog found it stalled ({detail}). + +An assignment means we want it FIXED. The deliverable is a PR, ideally \ +merged, not a triage comment and not a question back. If the issue holds a \ +design fork, pick the option you would recommend, say so in the PR body, and \ +let review move it; only a decision that is genuinely somebody else's stays a \ +question. + +Start by reading the issue and its comments -- an earlier session may have \ +left analysis there, and re-triaging it from scratch is the exact waste this \ +watchdog exists to stop. Check what else is running before you begin \ +(agent-box-session ls, agent-box-webhook ls); if another session has picked \ +this up since, remove yourself rather than working beside it. + +Work in your own detached worktree (git worktree add --detach) under \ +~/worktrees, never in a shared checkout, and commit early -- an agent restart \ +destroys anything uncommitted.
