markdown

A set of rules for creating and editing Markdown files, including header formatting and spacing.

In plain words
What is it for?
It is for formatting headings, limiting heading depth, and applying specific rules to Markdown and MDC files.
Why use it?
It prevents inconsistent Markdown structure and makes documents easier to read and maintain.

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.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 105 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
Token cost

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 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 yesterday.

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 Rules

Headers

  • All headers must be followed by exactly one blank line
  • Use ATX-style headers (# syntax) rather than underline style
  • Maximum of three header levels in most cases
  • Header text should be concise and descriptive

See rules.mdc for specific rules for .mdc files.

Changes

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.

markdown is a cursor rule published in the GitHub repository panozzaj/cursor-rules (3 stars, last pushed 1y ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 105 tokens. 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.
