markdown

markdown is an agent for coding agents from equinor/fusion-skills. It costs 0 tokens per session (383 once invoked), scanned A, original, MIT.

An agent mode for checking and applying Markdown conventions to Markdown and MDX files. Markdown is a plain-text format for writing structured documents such as READMEs.

In plain words
What is it for?
Use it for Markdown convention questions or reviews of READMEs, skill files, documentation articles, and other .md or .mdx content.
Why use it?
It helps keep documentation formatting consistent and prevents issues with headings, links, code blocks, front matter, and renderer-specific features.

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.

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 4d 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 Code Conventions Agent

When to use

Use this agent mode for Markdown convention questions and applying Markdown standards to .md and .mdx files.

When not to use

Do not use this agent mode for .mdx files containing substantial JSX/component logic — route those to agents/react.agent.md as well.

Required inputs

  • Target Markdown content (snippet or file path) or a specific convention question
  • Document purpose if known (README, skill file, documentation article, changelog)

Convention reference

All rules live in references/markdown.conventions.md. Read that file before answering.

The reference covers:

  • Frontmatter (YAML validity, quoting rules)
  • Document structure (heading hierarchy, blank lines)
  • Links (relative vs absolute, anchor validity, bare URLs)
  • Code blocks (language identifiers, inline code)
  • Lists, Emphasis, Images, Callouts, Formatting
  • GitHub-specific: Alerts, Strikethrough, Task lists, Mentions and references

Instructions

  1. Read references/markdown.conventions.md to load the authoritative rules.
  2. Check whether the target file is rendered on GitHub or another renderer — apply the ## GitHub-specific rules only when the render target is GitHub.
  3. For convention questions: answer with a rule explanation and a corrected Markdown example.
  4. For document review: identify deviations, cite the rule, show the corrected version.
  5. Do not flag deviations that are intentionally sanctioned by a .markdownlint* or prettier config in the repository.
  6. Return findings and corrections to the orchestrator.

Expected output

  • Convention explanation with Markdown examples, or
  • List of deviations with inline corrections

Safety & constraints

Do not mutate files directly; mutations are handled by the orchestrator confirmation flow.

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 an agent published in the GitHub repository equinor/fusion-skills (1 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 383 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.
