One command to prove relay init end to end on your own machine without touching the desktop app or your real configs:

./scripts/try-relay-init.sh --op 'op://AI Agents/Claude Setup Token/TOKEN'   # or CLAUDE_CODE_OAUTH_TOKEN=... / prompts for it
./scripts/try-relay-init.sh --tools codex                                     # no Claude token needed
./scripts/try-relay-init.sh --version 15.0.0-next.6 --keep                    # leave sessions up; --cleanup tears down

What it does:

1. Builds a throwaway environment: HOME, AGENT_RELAY_HOME, INSTALL_DIR, XDG dirs and core socket all live under /tmp/relay-try, and the project is ~/relay-try-project. The project isn't under a temp dir, because sessions in temp dirs never auto-join.
2. Copies ~/.codex/auth.json, and skips the Claude onboarding, trust and ~/.mcp.json prompts.
3. Runs npx agent-relay@<version> init --yes --tools ....
4. Starts real Claude Code (--permission-mode manual) and Codex in a private tmux server.
5. Checks that each session joins Relay by itself, that a DM from alice is injected, and that the reply reaches alice's inbox. It fails if an approval prompt appeared.
6. Runs init --uninstall and checks that no Relay files are left. Then it runs init --stop, kills what it started, and deletes the throwaway dirs and the copied auth.

Details:

• The Claude token is stripped of whitespace and held only in the tmux server's environment; the script never writes it to disk.
• The tool binaries are resolved before HOME changes. mise is pointed at its real trust state, so a trusted ~/mise.toml doesn't prompt inside the sessions.
• The script works with macOS's bash 3.2.

Verified on macOS against agent-relay@15.0.0-next.6: "All checks passed for claude, codex", and nothing was left running or on disk afterwards. shellcheck -S warning is clean.

No changelog entry: this is a developer script.

Walkthrough

The new shell script runs a selected agent-relay version in an isolated environment. It launches Claude and/or Codex sessions, checks Relay registration and direct-message replies, detects approval prompts, and verifies cleanup.

Changes: Relay initialization test harness

Layer / File(s)	Summary
Isolated environment and prerequisites scripts/try-relay-init.sh	The script parses options, configures isolated paths, validates tools and credentials, and prepares workspace state for selected Claude or Codex tools.
Launch sessions and verify Relay replies scripts/try-relay-init.sh	The script runs relay init, starts selected sessions in a dedicated tmux server, checks the Relay roster, sends DMs, and checks replies and approval prompts.
Keep-running and cleanup outcomes scripts/try-relay-init.sh	With --keep, the script leaves sessions running and prints instructions. Otherwise, it uninstalls Relay, checks for leftovers, stops processes, and removes owned temporary paths.

Estimated code review effort: 3 (Moderate) | ~25 minutes

The harness can expose a long-lived Claude credential to local process observers; this should be fixed before merging.

_{A rabbit checks the Relay doors,
Claude and Codex hop through.
A “pong” returns from each session,
While tmux keeps the test in view.
Then cleanup sweeps the paths away,
Unless the script says, “stay.”}

- Line 178: Update the `disabled` assignment for `REAL_HOME/.mcp.json` to use an
empty server list when the file is absent, while preserving read errors for an
existing file; avoid letting `pipefail` and `set -e` terminate the script for
the missing-file case.
- Around line 106-107: Update the cleanup flow around `relay()` and `ENV_FILE`
to source the environment file or delete the project directory only when each is
verified as created by this run; use a run-specific directory or a trusted
ownership marker for both paths.
- Line 163: Update the cleanup flow in the script around cleanup and KEEP:
register an EXIT handler that preserves the original exit status and runs
cleanup only when --keep is not set, and remove the explicit end-of-script
cleanup to prevent duplicate cleanup. Make the INT/TERM handler exit with an
interrupted status so the EXIT handler runs instead of allowing the script to
continue.

Follow-up Comments

Keep the OAuth token out of the tmux client argv.

244-245: Major · Security & Privacy · Quick win

Keep the OAuth token out of the tmux client argv.

When Claude is enabled, the token reaches tmux set-environment as a client-process argument. The private -L server socket does not protect that client process. A same-user observer, diagnostic tool, or another local user permitted to inspect process arguments can capture the long-lived token before tmux stores it. Clearing TOKEN afterward is too late.

Send the command through tmux control-mode input or another protected channel instead.

Suggested fix

-if [[ -n "$TOKEN" ]]; then tmux -L "$TMUX_SERVER" set-environment -g CLAUDE_CODE_OAUTH_TOKEN "$TOKEN"; fi
+if [[ -n "$TOKEN" ]]; then
+  printf '%s\n' "set-environment -g CLAUDE_CODE_OAUTH_TOKEN $TOKEN" |
+    tmux -C -L "$TMUX_SERVER" >/dev/null
+fi
