Adds tools/tmux/ to the framework source (previously only present in installed ~/.config/mosaic copies, never committed): - agent-send.sh: inter-agent messaging wrapper. Prepends the canonical addressing preamble [<src_host>:<src_session> -> <dst_host>:<dst_session>] (auto-detecting the sender), and delivers reliably to local OR remote panes. Remote delivery ships send-message.sh over ssh and runs it local to the target pane, sidestepping the ssh->nested-tmux Enter/C-m submission swallow; the remote needs only bash+tmux+base64 (no framework install required there). - send-message.sh: low-level reliable single-pane submitter (bracketed paste + Enter-flush + draft detection). Adds a -b base64 input for ssh-safe transport. - README.md: documents the addressing standard (replies flip the preamble) and the submission gotcha the helper exists to solve. Propagates to each host via install.sh rsync on next framework upgrade. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# agent-send.sh — standard inter-agent tmux messaging for the Mosaic stack.
|
|
#
|
|
# WHAT IT DOES
|
|
# Sends a message to another agent's tmux pane (local or on a remote host)
|
|
# with the canonical addressing preamble prepended:
|
|
#
|
|
# [<src_host>:<src_session> -> <dst_host>:<dst_session>] <message>
|
|
#
|
|
# The preamble makes every inter-agent message self-identifying, so a fresh
|
|
# or context-wiped agent always knows who sent a message and to whom — no
|
|
# ambiguity about lanes or origin. Recipients replying should FLIP the
|
|
# preamble: [<dst> -> <src>] ... (this tool sends; it does not auto-reply).
|
|
#
|
|
# WHY A WRAPPER
|
|
# Reliable submission into an interactive REPL (Claude Code / Codex) is fiddly:
|
|
# a trailing Enter is often swallowed and the message sits as an unsubmitted
|
|
# DRAFT. tools/tmux/send-message.sh already solves that for a LOCAL pane via
|
|
# bracketed-paste + Enter-flush + draft-detection. For REMOTE targets this
|
|
# wrapper SHIPS send-message.sh over ssh (stdin) and runs it there, so the
|
|
# reliable send-keys happens local to the target pane — sidestepping the
|
|
# ssh->nested-tmux Enter/C-m swallow entirely. No mosaic install needed on
|
|
# the remote host; only bash + tmux + base64 (standard).
|
|
#
|
|
# USAGE
|
|
# agent-send.sh -s <dst_session> -m "message" # local target
|
|
# agent-send.sh -H user@host -s <dst_session> -m "message" # remote target
|
|
# agent-send.sh -H user@host -n <dst_hostname> -s <sess> -f msg.txt
|
|
# echo "msg" | agent-send.sh -H user@host -s <dst_session>
|
|
#
|
|
# OPTIONS
|
|
# -s DST_SESSION target tmux session (or session:window.pane) [required]
|
|
# -H SSH_TARGET ssh target (user@host) for a remote pane; omit for local
|
|
# -n DST_HOST hostname to show in the preamble for the target.
|
|
# Default: local hostname, or (remote) resolved via one ssh.
|
|
# -m MESSAGE message text (single- or multi-line)
|
|
# -f FILE read message from FILE instead of -m
|
|
# -S SRC_LABEL override source label "<host>:<session>" (default: auto)
|
|
# -r N Enter-flush attempts passed through (default 2)
|
|
# -v verbose: print pane tail after delivery
|
|
# -h help
|
|
#
|
|
# EXIT CODES (passed through from send-message.sh)
|
|
# 0 delivered/queued · 1 target not found · 2 still draft · 3 usage error
