Live handoff refused any session with more than 64 panes. The pane count was checked twice against MAX_FDS_PER_HANDOFF, and the transfer itself put every pane's pty master into one SCM_RIGHTS control message, so the guard was the only thing keeping the send inside the kernel's per-message limit. A session past the limit could only be updated by closing panes or by a normal restart, which ends every pane process. Send the descriptors in batches of 64 instead and drop both guards. The receiving side accumulates across recvmsg calls until the expected count arrives, bounds every SCM_RIGHTS payload it reads by the control bytes the kernel returned, rejects a batch that carries more descriptors than it asked for, and closes the descriptors it already holds on any failure. A session of 64 panes or fewer still produces one batch, so the bytes on the wire are unchanged and HANDOFF_VERSION stays at 1. refs #3393 Co-authored-by: kataokatsuki <kataokatsuki@users.noreply.github.com> Co-authored-by: JJ Liebig <jonathan.liebig@gmail.com>

the runtime your coding agents live on.
- detach without stopping work — herdr keeps terminals running in a background server when you close the client or lose your SSH connection. after a server or machine restart, herdr restores the saved layout and can resume supported agent sessions; the original processes do not survive. session state →
- several machines, one window — keep local work and saved ssh machines together, with a combined agent list and independent reconnects. remote machines →
- never hunt for the stuck one — every pane is marked working, blocked, or idle. when an agent stops and needs an answer, herdr says so.
- agent-native — agents drive herdr through the cli and socket api: they can spawn panes, prompt each other, and wait until another agent is genuinely blocked. agent skill →
- runs what you already run — claude code, codex, cursor, opencode, grok and the rest. herdr doesn't wrap or replace them; it owns their terminals.
- keyboard and mouse, both first-class — tmux-style prefix keys and click, drag, split. pick per moment, not per tool.
- plugins — extend panes and workflows. browse the marketplace →
- one rust binary, no electron — runs in whatever terminal you already use.
