What is handoff-claude?

A handoff method for moving an unfinished coding task to Claude Code through a portable written packet. The packet records the goal, decisions, Git state, checks performed, and next steps.

Use it when Claude Code should continue work started in Codex CLI or Grok Build, or when a fresh Claude session needs a concise project checkpoint.

A new coding agent may not have access to the previous agent's conversation. The packet preserves the working context without copying accounts, permissions, or session histories.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00051	$0.00369
Opus 5.5	$0.00020	$0.00148
Sonnet 5.5	$0.00010	$0.00074
Haiku 4.5	$0.00005	$0.00037

Security

Grade A, and why

handoff-claude 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 2mo 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 Claude Code

Use the shared session-relay workflow. Claude starts a new native session and reads the same vendor-neutral packet used by Codex and Grok.

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 <codex|grok> --to claude \
  --goal "..." --summary "..." --next "..."

"$RELAY" continue --to claude

The second command only prints the interactive command. Add --run when the user explicitly wants to launch it, or --headless for a one-shot claude -p continuation.

Claude Code's own --continue and --resume remain the right tools for resuming a Claude-native history. Use a Director packet when the source is another CLI, when a concise checkpoint is preferable, or when the workflow may later move again.

Profiles created with CLAUDE_CONFIG_DIR can still isolate authorized Claude accounts, but profile credentials, permissions, plugins, MCP configuration, and session histories are not copied into the packet.

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.
