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.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Output Handling · line 423 Model output is used without validation or sanitization. Unvalidated output injected into downstream contexts (SQL, shell, HTML) enables injection attacks and arbitrary code execution.Fix: Validate and sanitize all model output before using it in downstream contexts. Use parameterized queries for SQL, shell quoting for commands, and HTML encoding for web output.
What it costs to keep this loaded
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 | $0.00022 | $0.03427 |
| Opus 5 | $0.00011 | $0.01714 |
| Sonnet 5 | $0.00004 | $0.00685 |
| Haiku 4.5 | $0.00002 | $0.00343 |
Grade A, and why
hono-jsx 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 12d 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 — 623 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Hono JSX - Server-Side Rendering
Overview
Hono provides a built-in JSX renderer for server-side HTML generation. It supports async components, streaming with Suspense, and integrates seamlessly with Hono's response system.
Key Features:
- Server-side JSX rendering
- Async component support
- Streaming with Suspense
- Automatic head hoisting
- Error boundaries
- Context API
- Zero client-side hydration overhead
When to Use This Skill
Use Hono JSX when:
- Building server-rendered HTML pages
- Creating email templates
- Generating static HTML
- Streaming large HTML responses
- Building MPA (Multi-Page Applications)
Not for: Interactive SPAs (use React/Vue/Svelte instead)
Configuration

Basic Usage
Simple Rendering
import { Hono } from 'hono'
const app = new Hono()
app.get('/', (c) => {
return c.html(
<html>
<head>
<title>Hello Hono</title>
</head>
<body>
<h1>Hello, World!</h1>
</body>
</html>
)
})
Components
import { Hono } from 'hono'
import type { FC } from 'hono/jsx'
// Define props type
type GreetingProps = {
name: string
age?: number
}
// Functional component
const Greeting: FC<GreetingProps> = ({ name, age }) => {
return (
<div>
<h1>Hello, {name}!</h1>
{age && <p>You are {age} years old.</p>}
</div>
)
}
const app = new Hono()
app.get('/hello/:name', (c) => {
const name = c.req.param('name')
return c.html(<Greeting name={name} />)
})
Layout Components
import type { FC, PropsWithChildren } from 'hono/jsx'
const Layout: FC<PropsWithChildren<{ title: string }>> = ({ title, children }) => {
return (
<html>
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>{title}</title>
<link rel="stylesheet" href="/styles.css" />
</head>
<body>
<header>
<nav>
<a href="/">Home</a>
<a href="/about">About</a>
</nav>
</header>
<main>{children}</main>
<footer>
<p>© 2025 My App</p>
</footer>
</body>
</html>
)
}
app.get('/', (c) => {
return c.html(
<Layout title="Home">
<h1>Welcome!</h1>
<p>This is my home page.</p>
</Layout>
)
})
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- 12d ago First seen · 623 lines · 22 tokens per session scan A 27592d74287f
hono-jsx is a skill published in the GitHub repository bobmatnyc/claude-mpm-skills (75 stars, last pushed 1mo ago), licensed MIT. It adds 22 tokens to every session and 3,427 once invoked, about $0.0001 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.
