1password

1password is a skill for Claude Code, Codex from otto-haus/otto. It costs 20 tokens per session (145 once invoked), scanned A, original, MIT.

A reference guide for using the 1Password command-line tool to work with secret references. It documents command patterns without reading or storing the actual passwords, tokens, or other secret values.

In plain words
What is it for?
Use it when documenting how a program can receive a credential at runtime from 1Password. It covers command examples and rules for handling secret references.
Why use it?
It helps keep credentials out of project configuration and prevents the agent from materializing secrets without approval. Sensitive reads and injection into commands require explicit permission.

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 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.

What it actually says

1Password skill (stub)

Triggers

  • 1password, op cli, secret reference, inject credential at runtime

Constraints

  • Red zone: any op read or secret materialization requires explicit approval
  • Otto never persists secret values — use Letta/keychain as system of record
  • Document commands only; user runs op locally

Autonomy

  • 1password.read: red
  • 1password.inject: red
op read "op://vault/item/field" # user-approved only
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.
