agent-comms
Agent Communication
Send messages to and read output from other tmux sessions running Claude Code or Codex. Built for coordination between parallel agent sessions.
Platform Support
Works identically on both platforms -- the underlying mechanism is tmux, not the AI agent. Sessions can communicate across platforms (a Claude Code session can message a Codex session and vice versa).
Setup
Make the script executable (one-time):
chmod +x ~/.claude/skills/agent-comms/scripts/agent-msg
Message Format
Always prefix messages with a header so the receiving session knows it's agent-to-agent:

alexa-cli
Control Amazon Echo/Alexa devices via the `alexacli` CLI. Use when the user asks to speak/announce on Echo devices, send voice commands to Alexa, control smart home devices, list Alexa devices, or trigger routines.
3project-spawn
Spawn a new Claude Code or Codex session in a project directory with context handoff. This skill should be used when discussion shifts to a different project/repo and the user wants to work on it in a dedicated session. Creates a handoff document with relevant context from the current conversation, then launches a new tmux session ready to continue.
3deep-dive
Deep dive on any topic. Decomposes into subtopics, researches each in parallel with thorough source gathering, then synthesizes into a comprehensive report (4,000-10,000+ words, 40-100+ sources). Scales depth dynamically based on topic complexity. Use when asked for a deep dive, deep research, comprehensive analysis, or thorough investigation of a topic.
2todoist-cli
Manage Todoist tasks via the `todoist` CLI. Use when the user asks to add tasks, complete tasks, list today's tasks, search tasks, manage projects/labels/sections, or interact with Todoist in any way.
2transcribe-and-analyze
Transcribe audio and video from URLs (YouTube, direct media links) using WhisperKit locally. Optionally analyze transcripts with AI when explicitly requested. Use when users provide URLs to media content and request transcription or speech-to-text conversion.
2claude-session-handoff
Recover working context from a prior Claude Code session by reading its JSONL conversation log and turning it into a clean handoff for Codex or another agent. Use when the user wants Codex to continue where Claude left off in the same repo, asks you to get up to speed on previous work, wants to resume a Claude thread after an interruption or outage, or needs help finding and summarizing the relevant file in ~/.claude/projects/.
