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

transfer 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 21d 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

node "${CLAUDE_PLUGIN_ROOT}/scripts/codex-companion.ts" transfer --args-stdin <<'STEREO_ARGS_Q7X2'
$ARGUMENTS
STEREO_ARGS_Q7X2

Present the command output to the user exactly as returned. Preserve the Codex session ID and the codex resume <session-id> command.

Transfer is deliberately one-directional: Claude Code session → resumable Codex thread. It takes no --model because the destination runtime is fixed, and there is no Codex → Claude direction because Codex threads resume in Codex. For Codex work that should be reviewed or continued on the Claude side, use /stereo:review --model claude:<family>[-<version>], /stereo:adversarial-review --model claude:<family>[-<version>], or the Claude role routes in /stereo:plan, /stereo:implement, and /stereo:quick.

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.
