handoff-codex

handoff-codex is a skill for Claude Code, Codex from claude-world/director-mode-lite. It costs 55 tokens per session (372 once invoked), scanned A, original, MIT.

A handoff workflow for passing an unfinished coding task from another command-line assistant to OpenAI Codex CLI. It packages the goal, current state, decisions, Git evidence, checks, and next steps.

In plain words
What is it for?
Use it to continue implementation or review work in Codex CLI after working in Claude Code or Grok. It can prepare an interactive or one-shot continuation.
Why use it?
It preserves the important context when changing command-line assistants, so the new Codex session does not have to reconstruct the work from scratch.

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

handoff-codex 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 9d 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

Handoff to Codex CLI

Use the shared session-relay workflow. Codex starts its own native session and reads a packet containing the goal, current state, decisions, Git evidence, verification, and next steps.

ROOT="${CLAUDE_PROJECT_DIR:-${GROK_WORKSPACE_ROOT:-}}"
[[ -n "$ROOT" ]] || ROOT="$(git rev-parse --show-toplevel 2>/dev/null || pwd)"
RELAY="$ROOT/.director-mode/bin/director-relay"
[[ -x "$RELAY" ]] || RELAY="$HOME/.claude/bin/director-relay"

"$RELAY" create \
  --from <claude|grok> --to codex \
  --goal "..." --summary "..." --next "..."

"$RELAY" continue --to codex

The second command prints the interactive codex invocation. Add --run only when the user wants it launched now. Use --headless when a one-shot codex exec continuation is appropriate.

Codex reads the repository's AGENTS.md, reusable skills from .agents/skills/, and generated agents from .codex/agents/. Confirm those surfaces with the installed CLI when debugging discovery.

Do not add bypass, approval, sandbox, or network flags as part of the handoff. Those controls belong to the Codex session and remain at their current native settings.

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.
