agent-glovebox: Skill for Claude Code

.claude/skills/markdown-block/SKILL.md

markdown-block is a skill for Claude Code from AlexanderMattTurner/agent-glovebox. It costs 84 tokens per session (496 once invoked), scanned A, original, Apache-2.0.

A skill that puts requested content inside a copyable Markdown code block. Markdown is plain text with symbols for headings, links, lists, and formatting.

In plain words
What is it for?
Use it when someone asks for raw, copyable, or paste-ready Markdown, including Markdown that contains its own code blocks.
Why use it?
It preserves the raw Markdown so users can paste it elsewhere without the application interpreting the formatting first. It also prevents nested code blocks from breaking the copied result.

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.

Security

Grade A, and why

markdown-block 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 actually says

Markdown Block Skill

Wrap the markdown you want the user to copy in a single fenced code block tagged markdown.

Never fold the prose inside the block

Write each paragraph on ONE line. The fence makes the text copyable; it does not make it code, so the never-wrap rule in root CLAUDE.md § Writing still binds. A hard wrap at 80 columns hard-codes a width the destination does not have, and the user pastes it into a GitHub issue that autowraps at its own.

Fence rules—escape inner code blocks

Triple-backtick fences cannot nest: an inner fence prematurely closes the outer one and breaks the copy block.

Rule: the outer fence must use strictly more backticks than the longest backtick run anywhere inside the content.

Inner content contains Outer fence to use
no backtick fences ```
``` (3 backticks) ````
```` (4 backticks) `````

Scan the content first, find the longest backtick run, then add at least one more backtick to the outer fence.

Example

User asks: “Give me a copyable markdown snippet for a README install section.”

Respond with a 4-backtick fence because the inner content has a 3-backtick block:

# Install

Run the following:

```bash
pnpm install
```

Other escaping notes

  • Tildes (~~~) are an alternate fence—apply the same “more than the longest inner run” rule if you choose them instead of backticks.
  • Indented (4-space) code blocks inside the markdown need no escaping.
  • Do not add commentary inside the fence. Put any explanation outside the block so the user copies clean markdown.

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.
