From e052012ab3ba80d011ce9dcb3b61a8c666f082fa Mon Sep 17 00:00:00 2001 From: Ethan Ligon & Sue Coder Date: Sun, 1 Nov 2026 19:22:34 +0000 Subject: [PATCH 1/5] Add agent status records and `sucoder attention` Detection, not steering, is what costs the human when several agent sessions run at once: knowing without looking which session has stopped at a permission prompt or is waiting for input. `sucoder sessions` cannot say; its pane probe tells a live agent from a bare shell, and a waiting Claude looks the same as a working one from ps. With `attention.hooks: true`, a SuCoder-launched Claude session gets hooks through `claude --settings` (added to the user's own; a command that already passes --settings is left alone). Each hook is plain POSIX shell that atomically writes ~/.sucoder/attention/--.rec wherever the agent runs: a header line and the hook's JSON payload. Notification marks the session waiting (permission prompt, or about a minute idle at the prompt); PostToolUse records only its event name, never the tool output. The hook always exits 0. `sucoder attention` reads this host's agent-account records and each cluster's, one round trip per cluster, and lists waiting sessions first. --watch redraws, keeps ~/.sucoder/attention.json and runs attention.notify_command for each session that starts waiting, using warm connections only. --tmux prints one status-bar line from that cache and skips configuration loading and startup checks. Verified against Claude Code 2.1.316 on vantage: a --settings hook fired and wrote a group-readable record. Design, the coordinator agent and open items: docs/attention.org. Tests: tests/test_attention.py (43). The full suite's 49 failures on vantage reproduce unchanged on main (Codex runner, SSH include, /tmp permission tests).

everything else waits for the human. + Its messages carry an agent's authority, not the human's, as the system prompt already says of peer messages. + +This needs no dispatch path, since it steers existing sessions through =message=;

=notify_command= covers that case's first need, knowing that something is waiting, without it. +Whether =--settings= reaches Claude through the Happier adapter is untested. + +* Prototype status (step 1) + +Built on branch =coder/attention-status=: + +- =sucoder/attention.py= :: hook command, record format and parser, listing script, renderers, transition detection. +- =sucoder/config.py= :: =AttentionConfig=, =attention: {hooks, notify_command}=. +- =sucoder/mirror.py= :: =_with_attention_hooks=, called beside the =--session-id= insertion in =launch_agent=;

Filter attention pushes, relay attention, add a coordinator example Only blocking notifications mark a session waiting. Claude tags each Notification with notification_type (read from Claude Code 2.1.316), and several are informational: auth_success, agent_completed, computer_use_*. The Notification hook now carries a matcher for the blocking types, each mapped to a kind -- permission, question or idle -- and a record from an older Claude without the field is classified by its message, else other. attention.notify_kinds (default all) and attention.notify_after_minutes (default 0) bound the push volume: every finished turn becomes an idle request a minute later. A request is one record, notified once; the watcher's first pass is its baseline. The notifier also gets SUCODER_ATTENTION_KIND. `attention --cached` lists the watcher's last pass without connecting. On the agent account with session_relay, `attention` and `--cached` run as the relay's user through `relay attention`, like `sessions`; --watch and --cache are refused there, so the caller can start no loop and pick no file under the human's home. The record keeps transcript_path, so a coordinator running as the agent account can read a local session's transcript, which peek cannot reach. examples/coordinator/: setup, a v0 brief (triage on request, one block per waiting session, send only what the human approves, never answer a permission prompt) and attention-notify, which posts to ntfy and types one sanitized line into the coordinator's tmux pane, skipping the coordinator's own mirror. The tmux route exists because `message` reaches cluster sessions only. Found on vantage and recorded, not changed: every coder-side sucoder command stops at the startup check, because ~coder/.sucoder/config.yaml is owned by coder. The relay needs that fixed by the human first. Tests: tests/test_attention.py now 70, including the notifier script through a fake tmux. Full suite: 2505 passed; the same 49 vantage failures as on main, none new.

Subject: [PATCH 3/5] List running sessions without records as untracked; fix agent-side startup A session launched before attention.hooks was on (or by an older SuCoder, or a harness without hooks) writes no record, and `sucoder attention` silently left it out: on vantage the coordinator could not see a Savio job or the SuCoder session, both started before the install. The listing now also asks what is running and shows a live session with no record, or only an `ended` one, as `untracked`: - this host: the process table. A local launch is `sudo -u bash -c '... cd || exit 1; umask ..; '` and cmdline is world-readable, so the human-side watcher sees it; the directory maps to a configured mirror, and a Claude --session-id gives the transcript path the coordinator reads; - a cluster: `squeue --me` fused into the existing records read (one round trip), mapped to mirror/target as `sessions` does; RUNNING jobs only; - a host without a scheduler: its sucoder- tmux sessions. Untracked sorts after idle, counts on the tmux line, never notifies. A live query that does not answer is an error, not an absence. Also: the startup check ran `sudo -u test -r config` even when already running as the agent, which needs a sudoers rule the agent lacks, so every coder-side command (relay, peek, message, attention) failed with "cannot read configuration" for a readable file. It now checks directly when the current user is the agent, as _get_use_sudo_for_agent already does for later commands.
