web_navigator

web_navigator is a skill for Claude Code, Codex from siddsachar/row-bot. It costs 20 tokens per session (725 once invoked), scanned A, original, Apache-2.0.

Guidance for researching websites and completing multi-step browser tasks, including reading pages, using multiple tabs, and filling forms carefully.

In plain words
What is it for?
Use it to research sites, extract visible page data, compare sources in separate tabs, scroll through content, and complete online forms.
Why use it?
It reduces mistakes by requiring a fresh page view after each action and by separating information gathering from later comparison.

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

web_navigator 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When the user asks you to browse a website, fill out a form, extract data from a page, or perform any multi-step browser interaction, apply these strategic patterns:

Research Patterns

  1. Snapshot First, Act Second — After every navigation or interaction, always read the snapshot before deciding your next action. Never chain clicks blindly.
  2. Progressive Disclosure — Start with the visible content. If you need more, scroll down and take another snapshot. Don't assume content below the fold exists or doesn't.
  3. Multi-Tab Research — When comparing options across sites (prices, reviews, specs), open each source in a separate tab. Gather all data first, then synthesise. This avoids losing context by navigating away.
  4. Read URL for Bulk Text — If you only need the text content of a page (no interaction needed), use read_url instead of the browser. Reserve the browser for when you need to click, scroll, or interact.

Form Filling

  1. Survey the Form — Before filling anything, take a snapshot to understand all the fields. Plan the fill order based on what you see.
  2. Type Carefully — Use browser_type with the correct ref for each field. After filling critical fields (payment, addresses), snapshot to verify the values took.
  3. Handle Dropdowns and Selects — Click the dropdown first, wait for the snapshot showing options, then click the desired option. Don't try to type into select elements.
  4. Confirm Before Submit — Always snapshot and summarise what you've filled in before clicking a submit button. Let the user verify.

Data Extraction

  1. Structured Extraction — When extracting tabular data (product listings, search results, comparison tables), present it in a clean markdown table or structured format.
  2. Pagination — If the data spans multiple pages, mention how many pages there are and ask whether to continue after the first page. Don't silently paginate through 50 pages.
  3. Save Long Results — For large extractions, offer to save results to a workspace file or memory rather than dumping everything into the chat.

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.
