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

agent-browser 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 10d 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.

agent-browser

Fast browser automation CLI for AI agents. Chrome/Chromium via CDP with accessibility-tree snapshots and compact @eN element refs.

Install: npm i -g agent-browser && agent-browser install

Workflow

Step 1: Navigate to a page

agent-browser goto "https://example.com"
agent-browser wait @e3                           # wait for element to appear
agent-browser html                                # get current DOM snapshot

The goto command navigates to a URL and waits for the page to load. Use wait to ensure specific elements are present before interacting. Always snapshot with html after navigation to get fresh @eN refs.

Step 2: Interact with elements

agent-browser click @e5                           # click element by accessibility ref
agent-browser type @e7 "hello world"              # type into input
agent-browser select @e9 "option-value"           # select dropdown option
agent-browser check @e12                          # toggle checkbox/radio
agent-browser hover @e15                          # hover over element
agent-browser press Enter                         # press keyboard key
agent-browser scroll down 500                     # scroll page by pixels
agent-browser drag @e5 @e20                       # drag element to target
agent-browser upload @e8 "C:\path\to\file.pdf"   # file input upload

All interactions use accessibility-tree element references (@eN). These are stable within a single page snapshot but invalidate after navigation or DOM mutations.

Step 3: Extract data or capture evidence

agent-browser screenshot page.png                 # full-page screenshot
agent-browser screenshot --element @e5 el.png     # element screenshot
agent-browser screenshot --full-page false vp.png # viewport-only screenshot
agent-browser text                                 # visible text content
agent-browser html                                 # full HTML source
agent-browser pdf output.pdf                       # generate PDF
agent-browser console                              # browser console logs
agent-browser network                              # network request log
agent-browser eval "document.querySelector('.price').innerText"  # run JS
agent-browser performance                          # Core Web Vitals metrics

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.
