What it does

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

Its SKILL.md is about 410 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

  • “/bitwarden”

Workflow steps

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

  1. human.click the username field.
  2. Wait 500 ms - 1 s, then snapshot().
  3. Look for the Bitwarden inline menu — an iframe subtree (frame-qualified
  4. Verify with snapshot({diff: true}), then submit.

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

Bitwarden loads about 408 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 199 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
~408

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.

Bitwarden

Bitwarden autofills through an inline menu iframe below the focused field. You click the menu; Bitwarden types the secret. You never see it.

Autofill flow

  1. human.click the username field.
  2. Wait 500 ms - 1 s, then snapshot().
  3. Look for the Bitwarden inline menu — an iframe subtree (frame-qualified refs) listing vault items.
    • Menu present: click the matching item via its aria-ref.
    • Menu absent but the field shows a Bitwarden shield badge: the vault is likely locked — follow the unlock flow below.
    • Neither: Bitwarden has nothing for this site; fall back to the credential-manager ladder (../credential-manager/SKILL.md).
  4. Verify with snapshot({diff: true}), then submit.

Unlock flow

  1. openPage('chrome-extension://nngceckbapebfimnlniiiahkandclblb/popup/index.html').
  2. The master password must come from the user — in a headed session ask them to unlock in the visible window and confirm. Never guess it.
  3. closePage the popup, usePage back to the sign-in tab, and reload the page before re-focusing the field.

Cautions

  • Inline autofill may be disabled in Bitwarden's settings; if focusing never shows a menu while unlocked, fall back to the credential-manager ladder rather than fighting the extension.
  • The menu iframe is reachable only via its aria-refs or on-screen box — page CSS selectors do not reach it.
