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 | $0.00108 | $0.01815 |
| Opus 5 | $0.00054 | $0.00907 |
| Sonnet 5 | $0.00022 | $0.00363 |
| Haiku 4.5 | $0.00011 | $0.00181 |
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 5d 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 — 194 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Browser Automation with agent-browser
The CLI uses Chrome/Chromium via CDP directly. Install via npm i -g agent-browser, brew install agent-browser, or cargo install agent-browser. Run agent-browser install to download Chrome. Existing Chrome, Brave, Playwright, and Puppeteer installations are detected automatically. Run agent-browser upgrade to update to the latest version.
Hive Integration
Always use Hive before interacting with any webpage element. Hive is a collective intelligence layer — it stores proven selectors and interaction methods contributed by all agents. Using it means you start with what already works instead of discovering from scratch every time.
Before every interaction
- Extract the domain from the current URL (e.g. "github.com", "reddit.com").
- Define a clear
action_key(e.g. "click_submit_button", "fill_search_input", "click_reply"). - Call
hive_pullwith the domain and action_key. - If blocks are returned, try them top-down by rank:
type: "css"→ use as a CSS selector with agent-browsertype: "xpath"→ use as an XPathtype: "aria"→ use as an ARIA labeltype: "visual"→ use the description for screenshot-based targeting (screenshot --annotate)
- After each attempt, call
hive_vote— "up" if it worked, "down" if it failed, then try the next. - If all blocks fail or none exist, discover the method yourself (snapshot, screenshot, DOM), then call
hive_contributewith what worked.
After discovering a new method
Once you successfully interact with an element by your own discovery:
- Note the domain and action_key.
- Identify what worked: CSS selector, XPath, ARIA label, or visual description.
- If you tried a Hive block that failed before finding this, pass its block ID as
parent. - Call
hive_contributeso every future agent benefits.
If Hive is not available
If hive_pull, hive_contribute, or hive_vote are not available as tools, Hive is not enabled. Let the user know:
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.
- 5d ago First seen · 194 lines · 108 tokens per session scan A e3653adf12c4
agent-browser is a skill published in the GitHub repository Brainrot-Creations/claude-plugins (22 stars, last pushed 2mo ago), licensed MIT. It adds 108 tokens to every session and 1,815 once invoked, about $0.0005 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.
Other skills, from other repositories
broken-link-checker
Scans a website to find broken links (404s, 500s). Crawls internal pages, identifies broken outbound links, and reports source pages for easy fixing. Use this when the user asks to "check for broken links", "find 404s", "audit my links", or "is my site healthy".
test-site
Tests a deployed, activated Power Pages site at runtime using browser-based navigation, page crawling, and API request verification via Playwright. Use when the user wants to test, verify, or smoke-test their deployed site.
preview-screens
Use when the user wants to preview generated screens in a browser without starting Metro / a simulator — for example after /create-mobile-app finishes or after /edit-app regenerates a screen.
qa
Browser-based QA verification. Launches a real browser, navigates the app, clicks buttons, fills forms, and tests user flows. Works as a standalone skill or as a phase end condition in campaigns. Requires Playwright (optional dependency, graceful skip if not installed).
cloudflare-browser-rendering
Cloudflare Browser Rendering with Puppeteer/Playwright. Use for screenshots, PDFs, web scraping, or encountering rendering errors, timeout issues, memory exceeded.
youtube-cli
Searches YouTube and fetches video transcripts via the cli-web-youtube command-line tool — video search, video details (views, duration, description, keywords), trending by category, channel info, and timestamped transcripts/captions with language selection and translation. Use when the user asks about YouTube…
