1password

1password is a skill for Claude Code, Codex from spinabot/brigade. It costs 44 tokens per session (718 once invoked), scanned A, a copy of 1password, MIT.

A guide for installing and using the 1Password command-line tool, which lets programs access stored passwords and other secrets. It covers sign-in, desktop-app integration, multiple accounts, and running commands safely through tmux, a terminal session manager.

In plain words
What is it for?
Use it to install or verify the 1Password CLI, sign in, check the active account, and read, inject, or run commands with stored secrets.
Why use it?
It helps prevent setup and authentication errors when a command-line workflow needs secrets. It also defines the required checks before reading or injecting sensitive values.

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

1password 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 4d 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.

Origin

This is a copy

95% identical to 1password — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

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="${BRIGADE_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/brigade-tmux-sockets}"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/brigade-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.
Files

What ships with it

2 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.
