Reply Slack

Send a message to a Slack channel or thread via the Crewly backend API. This bypasses terminal output parsing and delivers the message directly to Slack, avoiding PTY line-wrapping and ANSI artifacts.

Usage

# Legacy JSON argument (kept for backwards compatibility)
bash config/skills/orchestrator/reply-slack/execute.sh '{"channelId":"C0123","text":"Task completed successfully!"}'

# Recommended multi-line usage with stdin
cat <<'EOF' | bash config/skills/orchestrator/reply-slack/execute.sh --channel C0123 --conversation "$CHAT_CONVERSATION"
Deploy complete ✅

Tests are green and artifacts published.
EOF

With thread reply (any style):

bash config/skills/orchestrator/reply-slack/execute.sh '{"channelId":"C0123","text":"Update: tests passing","threadTs":"1707430000.001234"}'
