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

rc-bridge 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 5d 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

/rc-bridge — Bridge this Codex pane to the phone

Launch a Haiku relay pane paired with this Codex pane, making it controllable from the Claude Code iOS app.

Steps

1. Get own pane ID and register

Run: echo $TMUX_PANE → store as CODEX_PANE.

Call MCP tool:

mcp__urc-coordination__register_agent(pane_id=CODEX_PANE, cli="codex-cli", role="engineer", pid=0)

2. Launch bridge

Run shell command (takes ~15-20s — includes orphan detection, relay spawn, bootstrap, and /remote-control activation):

bash urc/core/urc-spawn.sh bridge CODEX $TMUX_PANE $TMUX_PANE

The output is JSON:

  • {"status":"ready","relay":"%NNN","target":"%NNN","cli":"CODEX","method":"new"} — new relay spawned
  • {"status":"ready","relay":"%NNN","target":"%NNN","cli":"CODEX","method":"re-paired"} — orphaned relay reused
  • {"status":"failed","error":"..."} — spawn failed

3. Confirm to user

If status is "ready", display:

RC Bridge launched!

  Relay:  RELAY_PANE (Haiku)
  Target: CODEX_PANE (Codex)
  Method: new / re-paired

This pane is now accessible from your
Claude Code phone app via the relay.

If status is "failed", display the error message.

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.
