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 | $0.00041 | $0.00915 |
| Opus 5 | $0.00020 | $0.00458 |
| Sonnet 5 | $0.00008 | $0.00183 |
| Haiku 4.5 | $0.00004 | $0.00092 |
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 3d 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 — 145 lines — stays where its author put it; the contents beside it link to each section on GitHub.
agent-browser — Browser Automation CLI
A headless browser automation tool by Vercel Labs. Open web pages, interact with elements, extract information, and take screenshots.
Installation
If not already installed:
npm install -g agent-browser && agent-browser install
npm install -g agent-browser: Install the CLIagent-browser install: Download Chrome for Testing (first time only; add--with-depson Linux)
Verify installation:
agent-browser --help
Basic Workflow
1. open <url> → Open a page
2. snapshot -i → Get interactive element snapshot (refs: @e1, @e2, etc.)
3. click/fill/scroll → Interact using refs
4. snapshot -i → Re-check state after interaction
5. screenshot → Save screenshot if needed
Important: Always run snapshot -i before interacting to get element refs.

Snapshot (Page Structure)
agent-browser snapshot # Full page

agent-browser wait @e1 # Wait for element
agent-browser wait --text "Success" # Wait for text
agent-browser wait --load networkidle # Wait for network idle
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 xuiltul/animaworks (254 stars, last pushed 3d ago), licensed Apache-2.0. It adds 41 tokens to every session and 915 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 2026-08-30.

Required before any hive-browser CLI command. The browser is driven from the terminal by running hive-browser ... --json via terminalexec — not via MCP tools.
