Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.01391 |
| Opus 5 | $0.00016 | $0.00696 |
| Sonnet 5 | $0.00007 | $0.00278 |
| Haiku 4.5 | $0.00003 | $0.00139 |
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 11d 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 — 197 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agent-browser
Automate browser interactions for testing, screenshots, and web scraping using the agent-browser CLI tool from Vercel Labs.
Installation
npm install -g agent-browser
agent-browser install
Core Workflow (AI-Optimized)
The recommended pattern uses reference-based selection:
# 1. Navigate to page
agent-browser open "https://example.com"
# 2. Get interactive elements with refs
agent-browser snapshot -i
# 3. Interact using refs (@e1, @e2, etc.)
agent-browser click @e2
agent-browser fill @e3 "text"
Commands Reference
Navigation
agent-browser open <url> # Navigate to URL
agent-browser back # Go back
agent-browser forward # Go forward
agent-browser reload # Reload page
Snapshot (Get Element Refs)
agent-browser snapshot # Full accessibility tree
agent-browser snapshot -i # Interactive elements only
agent-browser snapshot -c # Compact (remove empty elements)
agent-browser snapshot -d 3 # Limit depth to 3
agent-browser snapshot --json # JSON output for parsing
Interaction
agent-browser click @e1 # Click by ref
agent-browser click "#submit" # Click by CSS selector
agent-browser dblclick @e1 # Double-click
agent-browser fill @e3 "text" # Clear and fill input
agent-browser type @e3 "text" # Type into element
agent-browser hover @e1 # Hover element
agent-browser focus @e1 # Focus element
agent-browser check @e1 # Check checkbox
agent-browser uncheck @e1 # Uncheck checkbox
agent-browser select @e1 "value" # Select dropdown option
agent-browser drag @e1 @e2 # Drag and drop
agent-browser upload @e1 file.pdf # Upload file
Keyboard
agent-browser press Enter # Press key
agent-browser press Control+a # Key combination
Scrolling
agent-browser scroll down 500 # Scroll down 500px
agent-browser scroll up 500 # Scroll up 500px
agent-browser scrollintoview @e1 # Scroll element into view
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.

agent-browser is a skill published in the GitHub repository itsnex1s/awesome-claude-skills (5 stars, last pushed 6mo ago), licensed MIT. It adds 33 tokens to every session and 1,391 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
