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 5.1 | $0.00045 | $0.02221 |
| Opus 5.5 | $0.00018 | $0.00888 |
| Sonnet 5.5 | $0.00009 | $0.00444 |
| Haiku 4.5 | $0.00005 | $0.00222 |
Grade A, and why
mathjax-rendering 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 2mo 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 — 356 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MathJax Rendering in Obsidian
Obsidian uses MathJax to render LaTeX math expressions. This skill covers essential syntax for mathematical notation.
For complete symbol tables and advanced commands, see reference.md.
1. Basic Syntax
Inline vs Block
Inline: The equation $E = mc^2$ appears within text.
Block (centered, display-style):
$$
\int_0^{\infty} e^{-x^2} dx = \frac{\sqrt{\pi}}{2}
$$
- Inline (
$...$): Compact, flows with paragraph - Block (
$$...$$): Larger, centered, multi-line capable
2. Fractions and Roots
\frac{a}{b} % Standard fraction
\sqrt{x} % Square root
\sqrt[n]{x} % n-th root
\binom{n}{k} % Binomial coefficient
Examples:
$$
\frac{d}{dx}\left(\frac{f(x)}{g(x)}\right) = \frac{f'(x)g(x) - f(x)g'(x)}{[g(x)]^2}
$$
$$
\sqrt{a^2 + b^2} = c \qquad \sqrt[3]{27} = 3
$$
3. Superscripts and Subscripts
$x^2$ % Superscript
$x_1$ % Subscript
$x_i^2$ % Both combined
$x^{10}$ % Multiple characters need braces
$x_{n+1}$ % Expression as subscript
Note: Use braces {} for multi-character exponents/subscripts.

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.

mathjax-rendering is a skill published in the GitHub repository BitYoungjae/marketplace (6 stars, last pushed 5mo ago), licensed MIT. It adds 45 tokens to every session and 2,221 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
