session-relay

session-relay is a skill for Claude Code, Codex from claude-world/director-mode-lite. It costs 82 tokens per session (1,080 once invoked), scanned A, original, MIT.

A handoff guide for continuing repository work between Claude Code, Codex CLI, and Grok Build, which are different coding-agent tools.

In plain words
What is it for?
Use it for cross-tool handoffs, context-limit checkpoints, multi-step relays, or receiving an existing handoff packet.
Why use it?
It preserves the current goal, progress, and constraints in a portable packet when work moves to another tool or session.

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

session-relay 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.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/director-relay.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cross-CLI Session Relay

Move work between Claude Code, Codex CLI, and Grok Build through a portable handoff packet. A relay starts a new native session in the receiving CLI; it does not pretend that vendor session IDs or private conversation histories are interchangeable.

Resolve the relay

Prefer the first available implementation:

  1. <project>/.director-mode/bin/director-relay;
  2. $HOME/.claude/bin/director-relay from Bootstrap Kit;
  3. scripts/director-relay.py beside this SKILL.md for plugin-only use.

If only the bundled script exists, invoke it with python3. Do not install a hook or change a permission setting just to use the relay.

Leave a packet

Summarize the current state from repository evidence, then run:

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|codex|grok> \
  --to <claude|codex|grok> \
  --goal "The outcome the user requested" \
  --summary "The concise current state" \
  --completed "One completed result" \
  --decision "One decision and why it was made" \
  --next "The first concrete next step" \
  --verification "A command and its actual result" \
  --blocker "A real blocker, if any"

Repeat list flags as needed. The tool captures branch, HEAD, git status --short, and diff statistics. It deliberately does not copy file contents, credentials, environment variables, or raw transcripts.

If a native session ID is available, add --session-id; it remains metadata for the source CLI and is never sent to another vendor as a resume token.

For a second or later handoff in the same chain, add --parent to link the new packet to the project's current latest.json, or --parent <packet.json> to name a specific parent. Protocol v2 records the root packet, parent, hop, and route while remaining able to read v1 packets.

Files

What ships with it

3 files 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.
