urc

urc is a skill for Claude Code, Codex from sidkandan/universal-remote-control. It costs 23 tokens per session (151 once invoked), scanned A, original, MIT.

A command that connects a Codex or Gemini terminal pane to the Claude Code phone app and detects which command-line tool is in use.

In plain words
What is it for?
Use it to list available panes when no argument is given, or to delegate a task from the current terminal pane and display the resulting status.
Why use it?
It lets you hand work from a terminal pane to the phone app and reports whether the handoff succeeded or failed.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

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 4d ago.

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 it actually says

/urc

Run this ONE command. Display the JSON result. Done.

bash "${CLAUDE_PLUGIN_ROOT:-.}/urc/core/urc-dispatch.sh" "$ARGUMENTS" "$TMUX_PANE"

If status is "delegated": say "RC Bridge will be viewable in the Claude app when ready." If status is "error": display the error message. If no argument was given: it lists available panes — display that list.

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.
