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.

rpg 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 1mo 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 installs
The manifest is a name and a version. 7 skills, 5 agents, 4 hooks travel with it, and installing the plugin installs all of them — 319 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.

rpg is a plugin published in the GitHub repository protoLabsAI/mythx-mcp (2 stars, last pushed 1mo ago), 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 2026-08-31.
Other plugins, from other repositories
doom
Doom above the Claude Code prompt: a corridor shooter: imps, a shotgun, and the floor below. Plays while Claude works, pauses when the turn ends, keeps your best score; zero tokens. A single game split out of cc-arcade (MIT, Seza Akgün). Needs an interactive terminal with a mouse.
claude-status-bar
Menu bar status indicator for Claude Code: animated spark, elapsed timer, and open/close lifecycle.
sipcode
Token-economy observatory for Claude Code: forensic per-session audit, A/B savings verifier, reproducible benchmark, and cost prediction — directly in Claude chat. Auto-installs via npx on first use; no separate npm install required.
unity-dev
Unity C# development workflow with architecture design, coding guidelines, testing patterns, and specialized review agents.
obsidian-router
Slash commands, skills, sub-agents, and hooks for the obsidian-mcp-router multi-vault MCP server — and, since v0.56.0, the MCP server itself: installing the plugin installs the server, and one update refreshes server + commands + skills + hooks together. 54 /obsidian-router: commands across four layers: (1) 18 wrapper.
claude-code-desktop-sync
Keeps MCP-server config in sync between Claude Code and Claude Desktop via a SessionStart hook, and reports the manual steps for anything that can't be auto-synced.
