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

c-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 4d 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.

What it actually says

Browser Automation

agent-browser (Vercel)

Navigate and interact with web pages using structured snapshots:

# Open a URL
agent-browser open "https://example.com"

# Get interactive element snapshot (shows clickable refs)
agent-browser snapshot -i

# Click an element by ref
agent-browser click @e2

# Fill a form field
agent-browser fill @e5 "search query"

# Take annotated screenshot
agent-browser screenshot --annotate

# Type text
agent-browser type "hello world"

# Press keys
agent-browser press Enter

playwright-cli (Microsoft)

Token-efficient browser automation designed for AI agents:

# Install browser (first time)
playwright-cli install-browser

# Navigate to URL
playwright-cli navigate "https://example.com"

# Get page snapshot
playwright-cli snapshot

# Click element
playwright-cli click "Submit button"

# Fill input
playwright-cli fill "Search" "query text"

# Screenshot
playwright-cli screenshot

Guidelines

  • Use agent-browser for AI-driven web interaction (snapshot-ref pattern)
  • Use playwright-cli for structured automation and testing flows
  • Always check snapshots before clicking — element refs change between pages
  • For login flows, navigate step by step and verify each page loads
  • Respect robots.txt and rate limits when scraping

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.
