# Markdown authoring

Keep your Markdown files clean and consistent before anyone else reads them

## What this does

You've written a document in Markdown and you're not sure the formatting is right or the wording holds together. This tidies the file and checks it against the GitHub flavour of Markdown, both by automated checks and by reading it for sense. Useful before publishing docs or opening a pull request.

### Top 3 things it does for you

- Clean up the formatting in a Markdown file
- Check my docs for formatting problems
- Review whether a document actually reads well

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Markdown authoring

This formats and validates Markdown files against GitHub Flavored Markdown standards, so documents follow the same conventions rather than drifting apart file by file.

Checking happens two ways. Automated linting catches the mechanical formatting issues, and a manual semantic review looks at the document as something a person has to read and understand.

## Questions

### Is Markdown authoring safe to install?

AIR scanned this exact version of Markdown authoring and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit f92a0fd6d822, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/markdown.

### How do I install Markdown authoring?

Open https://airmarket.ai/app/markdown on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/DaveSkender/Stock.Indicators/tree/f92a0fd6d8228dd0ad9b0d028f00cb6384e99f5e/.agents/skills/markdown.
