Browser tools
Screenshots, styled PDFs, page-to-Markdown, recordings, and scripted flows, backed by a bundled Chromium.
Five browser_* tools run on a Chromium that bun install pulls once (~150MB). Outputs land in <HOME>/reports/captures/<timestamp>-<name>.<ext>. Activate the Browser pack in configure-skills to pre-grant the permissions; without it, the first call confirms.
| Tool | Output | Use it for |
|---|---|---|
browser_screenshot | PNG | Any URL or local HTML / Markdown file; fullPage for the whole scroll |
browser_pdf | PDF (A4) | Markdown (Mermaid rendered) or HTML to print-styled PDF |
browser_markdown | Markdown | Any URL, including client-rendered SPAs, to clean LLM-friendly Markdown via Readability |
browser_record | WebM | Drive a page through navigate / scroll / wait steps and capture the run |
browser_flows | varies | Run a named, repeatable flow in a visible browser: scrape, fill a form, click through a task |
All take the same input: a URL, a file:// URL, or a path. screenshot and pdf render local Markdown through a styled CSS so Mermaid comes through; markdown does the reverse.
you > screenshot https://acme.com and call it acme-landing
you > render ~/Documents/business-plan.md to PDF
you > convert https://example.com to markdown, make sure the JS-rendered sections come through
you > record a 15-second tour of acme.com: scroll halfway, wait 2s, scroll to the bottomWeb search
The Browser pack also carries web_search, a direct call to the Perplexity Search API with citations. Activate it in configure-skills, then put PERPLEXITY_API_KEY in .kevin/secrets/.env in your editor. Pay-as-you-go; a $5 credit lasts most personal users days to weeks. See Accounts.
Flows
browser-flows drives a visible browser through pluggable flows; hacker-news ships as the reference. Write your own for any repeatable multi-step task on a site you use.
macOS sandbox
Browser launch can fail inside a host's sandboxed subprocesses. If it does, run playwright install chromium once from a normal terminal so the binary is cached.
