AI coding workflows

Preview and edit AGENTS.md and CLAUDE.md in Finder

Your coding agent keeps writing Markdown. Press Space on any of it in Finder and read the rendered document, then click the line that's wrong and retype it. Glance saves plain Markdown straight back to disk.

The files your agent leaves behind

Agentic coding tools filled every repo with convention files that steer how an assistant behaves:

• AGENTS.md, the cross-tool standard for agent instructions
• CLAUDE.md, project guidance for Claude Code
• SKILL.md files, specs, plans, prompt libraries, and changelogs

You read these far more often than you write them, and you read them to check one line. Press Space without a Markdown renderer installed and macOS hands you the raw source: literal # marks, unstyled code fences, tables collapsed into pipes.

Space to read it

Glance renders the file the moment you press Space. Headings and tables land in real typography, fenced code carries syntax colors, and Mermaid diagrams and LaTeX equations draw as images. Glance lays the page out with Core Text and Core Graphics, so no browser engine loads and nothing downloads from a CDN. Pressing Space makes zero network requests.

Long instruction files stay workable. Press ⌘F to search the document with every match highlighted, ⌘G to walk through them, and pinch to zoom around your pointer.

Click to fix it

Every other Markdown viewer on the Mac stops here. When the instruction is wrong, you close the preview, find the file, open an editor, hunt for the line, change it, and save.

In Glance you click the sentence and type. Select two words and a formatting toolbar appears. Open a line with ## for a heading or - for a bullet, edit a table cell and press Tab to move on, or click a Mermaid diagram and rewrite its source. Glance writes plain Markdown back to the file, so the next agent run reads your correction.

Quick Look previews stay read-only, the way macOS intends. Press Space to read, then Return to open the same page in Glance and start typing.

Leave the editor alone

Your agent is running in that window. Switching to it to fix one line in CLAUDE.md costs you the context you were holding, and half the time the file is open in a tab you have to hunt for. Glance opens the file on its own, from Finder, in about a second.

If you are checking several at once, ⌘T puts the next one in a tab of the same window, and ⌘\ opens the raw Markdown beside the rendered page when you want to see exactly what the agent wrote.

When a spec needs to go to someone who does not want a repo, press ⌘P to print it or ⇧⌘E to export a PDF. Glance paginates the document as it draws it, breaking between lines and table rows rather than through them.

Set it up

Download Glance, drag it into Applications, and open it once so macOS registers the Quick Look extension. Select any .md file and press Space. The full walkthrough lives on the preview Markdown in Finder guide, and the Markdown Quick Look overview covers what else renders.
