At a glance

Inter-agent communication via the msg CLI. An agent skill from pchalasani/claude-code-tools.

  • SKILL.md covers Registration, Sending Messages, Replying and Receiving Messages, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Msg is an agent skill from pchalasani/claude-code-tools. Inter-agent communication via the msg CLI. Use this when you need to send messages to other agent sessions, read incoming messages, or coordinate with other agents in tmux panes.

Its SKILL.md is about 360 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with tmux. The repository describes itself as: Practical productivity tools for Claude Code, Codex-CLI, and similar CLI coding agents. The licence is MIT.

Example prompts

  • “/msg”

What it can do on your machine

Read from SKILL.md and the folder at commit 0ca7320. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Msg loads about 362 tokens when it runs. Until then it costs about 46 tokens; SKILL.md has 123 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~46
When it runs · the whole SKILL.md, loaded when a task matches
~362

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

msg: Inter-Agent Communication

You can communicate with other coding agent sessions (Claude Code or Codex CLI) using the msg CLI tool.

Registration

Before sending or receiving messages, register yourself:

bash
msg register <your-name>

This auto-detects your tmux pane. You only need to do this once per session.

Sending Messages

Send a message directly to another agent:

bash
msg send <agent-name> "Your message here"

Send to multiple agents:

bash
msg send agent1,agent2 "Message for both of you"

Replying

bash
msg reply <agent-name> "Your reply here"

Receiving Messages

Check your inbox:

bash
msg inbox

This shows all unread messages grouped by thread and marks them as read.

Other Commands

bash
msg list          # List registered agents
msg threads       # List active threads
msg status        # Check system health

Guidelines

  • Keep messages concise -- they consume context in the receiving agent's session.
  • When replying, include enough context that the recipient understands without re-reading the full thread.
  • If you need to share code or file paths, reference them in the message text rather than pasting large blocks.

How many tokens does Msg use?

About 362 tokens (SKILL.md is roughly 1.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
