transfer

A command for moving the current Codex conversation into a resumable Claude Code session. Claude Code is a command-line coding assistant.

In plain words
What is it for?
Use it to transfer a session, verify the handoff, and receive the command needed to resume it in Claude Code.
Why use it?
It lets you continue the same work in another coding-agent environment instead of starting over.

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

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 2d 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

Transfer this Codex session into a Claude Code session file so the conversation can continue in Claude Code.

Raw slash-command arguments: $ARGUMENTS

Run exactly this command (the companion script is scripts/claude-companion.mjs inside this plugin's root directory; use an absolute path):

node "<plugin-root>/scripts/claude-companion.mjs" transfer "$ARGUMENTS"

Presentation:

  • Present the output verbatim, exactly as-is, including the Claude session ID, the claude --resume <session-id> command, and the directory it must be run from.
  • If verification failed, present the failure detail and remediation text without softening it.

Sandbox requirements:

  • The companion spawns the claude CLI, which needs network access to reach the Anthropic API.
  • If the sandbox blocks the command or Claude reports a connection error, rerun the same shell command with escalated permissions and explain why in the justification.
  • Do not work around a sandbox denial by improvising your own review or edits; the command's value is Claude's independent output.
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.
