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.

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 | $0.00034 | $0.01786 |
| Opus 5 | $0.00017 | $0.00893 |
| Sonnet 5 | $0.00007 | $0.00357 |
| Haiku 4.5 | $0.00003 | $0.00179 |
Grade B, and why
md scanned grade B with 1 finding 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.
Strips warnings and disclaimersmediumAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

100% identical to md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 386 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Markdown Clean Skill
Write clean, error-free markdown that IDEs and linters can parse without warnings.
When to Use
Invoke this skill when:
- Writing markdown documentation
- Creating README files
- Writing skill files with code examples

Common IDE Errors & Fixes
1. Nested Code Blocks
Problem: Code blocks inside code blocks cause parsing errors.
Error: Newline or semicolon expected
Wrong:
```markdown
Here is example:
```js
const x = 1;
```
```
Fix: Use different fence lengths (4 backticks for outer):
````markdown
Here is example:
```js
const x = 1;
```
````
Or use indentation for inner blocks:
```markdown
Here is example:
const x = 1;
```
2. Unclosed Code Blocks
Problem: Missing closing fence.
Error: Statement expected, Expression expected
Wrong:
```js
const x = 1;
// forgot to close
Fix: Always close with matching fence:
```js
const x = 1;
``` <-- closing fence
3. Mismatched Fence Characters
Problem: Opening with backticks, closing with tildes (or vice versa).
Error: Newline or semicolon expected
Wrong:
```js
const x = 1;
~~~
Fix: Match opening and closing:
```js
const x = 1;
### 4. Special Characters in Code Blocks
**Problem:** Unescaped backticks inside code blocks.
**Error:** `Unexpected token`
**Wrong:**
````markdown
```markdown
Use `code` for inline.
**Fix:** Use more backticks for outer fence:
`````markdown
````markdown
Use `code` for inline.
### 5. Pipe Characters in Tables
**Problem:** Unescaped `|` in table cells.
**Error:** `Column count mismatch`
**Wrong:**
```markdown
| Command | Description |
|---------|-------------|
| a | b | Creates a|b |
```
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.
- 5d ago First seen · 386 lines · 34 tokens per session scan B 6baf87a65489
md is a skill published in the GitHub repository hackermanishackerman/claude-skills-vault (2 stars, last pushed yesterday), licensed MIT. It adds 34 tokens to every session and 1,786 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 1 finding (strips warnings and disclaimers). It is 100% identical to md, differing in 0 lines, and is treated as a copy.
