A remote-control setup for operating Codex and Gemini command-line sessions from a phone. It uses tmux, a terminal tool that keeps multiple sessions running and organized.

Use it to control Codex and Gemini remotely, coordinate agents across command-line sessions, and relay work between them.

It lets you monitor and coordinate several AI coding sessions without staying at the computer running them.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Security

Grade A, and why

urc scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What ships with it

1 file beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

notify-me

Calls you back when an agent needs you. The moment an agent gets blocked waiting on your decision, notify-me pushes a notification to your phone (via ntfy) and/or plays a sound on your computer — so you can step away and still know when you're needed. Works with any agent that supports plugin hooks. No account, no…
