browser-form-automation

browser-form-automation is a skill for Claude Code, Codex from companion-inc/introspect. It costs 83 tokens per session (804 once invoked), scanned A, original, MIT.

A method for completing authenticated browser forms through their labels, fields, and page structure instead of relying on screen coordinates. It is suited to admin consoles, OAuth settings, secret managers, and other multi-field pages.

In plain words
What is it for?
Use it to configure or verify browser-based settings such as origins, redirect addresses, secrets, and account forms. It helps map fields, enter values reliably, and confirm the saved state.
Why use it?
It reduces errors caused by changing layouts, lost focus, scrolling, or typing into the wrong control. It also encourages checking the account, project, URL, and current values before editing.

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

browser-form-automation 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 2mo 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.

Browser Form Automation

Use When

  • The user asks you to configure or verify an authenticated web console, admin page, or form.
  • You are editing origins, redirect URIs, secrets, settings, or multi-field config in Chrome, Browser, or another browser automation surface.
  • A click/type attempt misses focus, typing lands nowhere, cmd+a selects the page, a console or side panel steals focus, or coordinates have changed after scrolling.

Near misses:

  • Read-only inspection or screenshots: use the Browser/Chrome skill directly.
  • A single visible button/link with no text entry: a coordinate or vision click is fine, then check state.
  • A provider API or secret-retrieval task: use local-secret-retrieval first; use this skill only when you must operate the web UI.

Procedure

  1. Start with the relevant Browser/Chrome skill and its runtime docs. Prefer the browser's semantic API: Playwright locators, accessible labels, form_input, or JavaScript DOM writes with dispatched input/change events.
  2. Map the form before changing it: list visible inputs/buttons with labels, placeholders, current values, disabled state, and the current URL/account/project. Confirm it is the expected account/project before writing.
  3. Use coordinates only to expose or open a control. Do not use stale x/y clicks as the main data-entry method for text fields.
  4. After any missed-focus signal, stop coordinate typing immediately. Switch to locator/DOM entry before retrying. A second blind click/type sequence without new DOM evidence is the failure pattern.
  5. When using DOM writes, mimic user input enough for frameworks: set the value through the native setter when needed, dispatch input and change, then read the field value back.
  6. Verify the result from the page's own state before saving/submitting: current input values, selected options, validation messages, success toast, or saved detail page.
  7. If saving transmits secrets, credentials, or external state and the user's request did not already authorize that exact destination/action, follow browser safety confirmation. Otherwise finish the authorized flow.

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.
