claude-transfer

claude-transfer is a skill for Codex from Beaulewis1977/claude-plugin-for-codex. It costs 43 tokens per session (442 once invoked), scanned A, original, MIT.

A tool for creating a concise, read-only handoff of the current coding-agent context to a new Claude session. The handoff records the goal, decisions, completed work, files, checks, and unresolved issues.

In plain words
What is it for?
Use it to transfer a task between Codex and Claude when a fresh session is required.
Why use it?
It prevents the next agent from needing the entire conversation while preserving the information needed to continue safely.

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

claude-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 10d 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

Claude Transfer

Transfer is a structured semantic handoff because Claude Code cannot natively import a Codex transcript turn by turn.

Handoff packet

Create a concise packet with these headings:

  • Goal and current user request
  • Requirements and constraints
  • Decisions and their rationale
  • Work completed
  • Repository and relevant-file context
  • Verification already performed
  • Unresolved issues
  • Recommended next action

Use --source for an explicitly selected packet file; otherwise send the handoff over stdin. Never scrape or claim to reproduce the full chat.

Workflow

  1. Resolve <plugin-root>/scripts/claude-companion.mjs to an absolute path.
  2. Make exactly one runtime invocation. Runtime action: transfer.
  3. Classify routine or bounded handoffs as normal, substantial reasoning as hard, and the most complex or high-stakes handoffs as very-hard. Pass that classification with --tier; explicit model and effort selections always win. Pass --cwd with the current workspace and --json as separate arguments. Honor explicit timeout choices. The runtime always creates a fresh session.
  4. Write the free-form handoff to stdin unless using --source. Never place handoff text in an option, argument, or shell command. Use an argument array; never concatenate or interpolate values into a shell command. Use the execution tool's separate stdin channel; if it exposes an interactive process session, send the text there and explicitly close stdin before waiting.
  5. Keep this read-only. The runtime forces plan permission and safe-mode. Never edit, write, fix, or apply changes, and do not request bypass permissions.
  6. Require only acknowledgement and readiness, not implementation. Return the session ID and exact continuation form claude --resume <session-id>.
Files

What ships with it

1 file beside SKILL.md 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.
