A setup and usage guide for the 1Password command-line tool, which retrieves secrets such as passwords and API keys without keeping them in plain text files or environment settings.

Use it to sign in, read secret references, inject secrets into configuration files, and run commands with temporary secret variables.

It keeps sensitive values out of source code and makes them available to commands only when needed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add cyborg-garden/hermes-agent-mt --skill 1password

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	$0.00037	$0.01216
Opus 5	$0.00018	$0.00608
Sonnet 5	$0.00007	$0.00243
Haiku 4.5	$0.00004	$0.00122

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 6d 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

86% identical to 1password — 4 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.

How it starts

The opening of the file, as written. The whole thing — 164 lines — stays where its author put it; the contents beside it link to each section on GitHub.

1Password CLI

Use this skill when the user wants secrets managed through 1Password instead of plaintext env vars or files.

Requirements

1Password account
1Password CLI (op) installed
One of: desktop app integration, service account token (OP_SERVICE_ACCOUNT_TOKEN), or Connect server
tmux available for stable authenticated sessions during Hermes terminal calls (desktop app flow only)

When to Use

Install or configure 1Password CLI
Sign in with op signin
Read secret references like op://Vault/Item/field
Inject secrets into config/templates using op inject
Run commands with secret env vars via op run

Authentication Methods

Service Account (recommended for Hermes)

Set OP_SERVICE_ACCOUNT_TOKEN in ${HERMES_HOME:-~/.hermes}/.env (the skill will prompt for this on first load). No desktop app needed. Supports op read, op inject, op run.

export OP_SERVICE_ACCOUNT_TOKEN="your-token-here"
op whoami  # verify — should show Type: SERVICE_ACCOUNT

Desktop App Integration (interactive)

Enable in 1Password desktop app: Settings → Developer → Integrate with 1Password CLI
Ensure app is unlocked
Run op signin and approve the biometric prompt

Connect Server (self-hosted)

export OP_CONNECT_HOST="http://localhost:8080"
export OP_CONNECT_TOKEN="your-connect-token"

Setup

Install CLI:

# macOS
brew install 1password-cli

# Linux (official package/install docs)
# See references/get-started.md for distro-specific links.

# Windows (winget)
winget install AgileBits.1Password.CLI

Verify:

op --version

Choose an auth method above and configure it.

Hermes Execution Pattern (desktop app flow)

Hermes terminal commands are non-interactive by default and can lose auth context between calls. For reliable op use with desktop app integration, run sign-in and secret operations inside a dedicated tmux session.

Note: This is NOT needed when using OP_SERVICE_ACCOUNT_TOKEN — the token persists across terminal calls automatically.

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.
