What it does

1password is an agent skill from BetterWright/betterwright. Read this when the browser profile has the 1Password extension and a login, signup, or payment form should be filled with it.

Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: A persistent, policy-guarded Playwright browser for AI agents — network policy, encrypted credential vault, proof screenshots, and CAPTCHA solving. The licence is MIT.

Example prompts

  • “/1password”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. human.click the username (or card-number) field.
  2. Wait 500 ms - 1 s for the menu iframe to render, then snapshot().
  3. Check the bottom of the snapshot for the 1Password menu — an iframe
  4. Verify from snapshot({diff: true}) that the fields are filled (password

What it can do on your machine

Read from SKILL.md and the folder at commit ec55a32. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

1password loads about 618 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 336 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~618

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

1Password

The 1Password extension autofills forms through an inline menu rendered in its own iframe. You click the menu; 1Password types the secret. You never see it.

Autofill flow

  1. human.click the username (or card-number) field.
  2. Wait 500 ms - 1 s for the menu iframe to render, then snapshot().
  3. Check the bottom of the snapshot for the 1Password menu — an iframe subtree (frame-qualified refs like f9e3) listing saved items as buttons (site + username per row).
    • Menu present: click the matching item via its aria-ref. Pick by site, username, and task context; if genuinely ambiguous, ask the user with masked options.
    • Only a status line like status: "1Password menu is available. Press down arrow to select." with no menu iframe: 1Password is locked — follow the unlock flow below.
    • Neither: 1Password has nothing for this site; fall back to the credential-manager ladder (../credential-manager/SKILL.md).
  4. Verify from snapshot({diff: true}) that the fields are filled (password values show as redacted). Then submit.

Unlock flow

  1. openPage('chrome-extension://aeblfdkhhhdcdjpifhhbdiojplfjncoa/popup/index.html').
  2. The master password must come from the user or the host — never from you. In a headed session, ask the user to unlock in the visible window and tell you when done. Do not guess or reuse site passwords.
  3. Close the extension tab (closePage), switch back to the sign-in tab (usePage), and reload the page — the inline menu does not appear on a page loaded while 1Password was locked.
  4. Re-click the field and continue from step 1 of the autofill flow.

Cautions

  • The menu is an extension iframe: it survives in snapshots, but CSS selectors and keyboard shortcuts from the page do not reach it — act on its aria-refs (or human.click its on-screen box).
  • After a reload or navigation the menu closes; re-focus the field to reopen.
  • Passkey dialogs ("Sign in with a passkey" / "Unlock 1Password") are also iframes; close them via their own buttons if you need password login instead.
  • Use the extension popup only to unlock — autofill from the sign-in page's inline menu, not from the popup.
