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 B, and why

1password-hardened scanned grade B with 2 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 12d 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.

Unrestricted tool accessmediumExcessive agency

A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

- Always single-quote user-provided values in `op` command arguments (vault names, item names, field labels) — unquoted shell metacharacters in item names could execute arbitrary commands.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Never pipe `op read` or `op run` output to network-transmitting commands (curl, wget, nc, ssh, etc.) — resolved secrets must not leave the local machine via network transmission. Use `op run` with environment injection

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

1Password CLI

Follow the official CLI get-started steps. Don't guess install commands.

References

  • references/get-started.md (install + app integration + sign-in flow)
  • references/cli-examples.md (real op examples)

Workflow

  1. Check OS + shell.
  2. Verify CLI present: op --version.
  3. Confirm desktop app integration is enabled (per get-started) and the app is unlocked.
  4. REQUIRED: create a fresh tmux session for all op commands (no direct op calls outside tmux).
  5. Sign in / authorize inside tmux: op signin (expect app prompt).
  6. Verify access inside tmux: op whoami (must succeed before any secret read).
  7. If multiple accounts: use --account or OP_ACCOUNT.

REQUIRED tmux session (T-Max)

The shell tool uses a fresh TTY per command. To avoid re-prompts and failures, always run op inside a dedicated tmux session with a fresh socket/session name.

Example (see tmux skill for socket conventions, do not reuse old session names):

SOCKET_DIR="${OPENCLAW_TMUX_SOCKET_DIR:-${CLAWDBOT_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/openclaw-tmux-sockets}}"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/openclaw-op.sock"
SESSION="op-auth-$(date +%Y%m%d-%H%M%S)"

tmux -S "$SOCKET" new -d -s "$SESSION" -n shell
tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- "op signin --account my.1password.com" Enter
tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- "op whoami" Enter
tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- "op vault list" Enter
tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200
tmux -S "$SOCKET" kill-session -t "$SESSION"

Guardrails

  • Never paste secrets into logs, chat, or code.
  • Prefer op run / op inject over writing secrets to disk.
  • If sign-in without app integration is needed, use op account add.
  • If a command returns "account is not signed in", re-run op signin inside tmux and authorize in the app.
  • Do not run op outside tmux; stop and ask if tmux is unavailable.

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.
