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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

groundhog 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 yesterday.
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 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.

groundhog is a plugin published in the GitHub repository dmytrome/groundhog (0 stars, last pushed today), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. 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 2026-09-07.
Other plugins, from other repositories
devharness
Run and debug a live app from inside Claude Code: breakpoints and variable inspection in Chrome and Node.js, managed dev servers, and replayable call history so setup is never re-driven by hand.
cli
Exposes Tauri MCP skills that can be used to control the webview of a running Tauri app from an AI assistant.
anti-detect-browser-skills
Drive a browser that presents one coherent real device: AntiBrow's kernel-level fingerprints, persistent isolated profiles, and per-profile proxies with matching timezone and WebRTC - from the JavaScript/Python SDK, via MCP tool calls, or as task-level site recipes that return JSON and can run across many identities…
claw-mux
cmux terminal integration: terminal I/O, topology control, browser automation, markdown viewer, notifications.
string
Use String apps and the web through one MCP tool. Install an app from a GitHub URL, read pages as markdown, run typed actions on documents — the whole String runtime exposed as a single mcpstringstring tool, with a skill that teaches Claude when and how to use it.
e2llm
Structured browser perception (SiFR) plus action in the browser you already use - Chrome, Firefox, Edge or Comet, signed in as you. Text-based: no screenshots, no vision model, no cloud browser. Works with any model.
