Does Claude Code read AGENTS.md? (No — here's what actually works)

For operators running Claude Code alongside Codex, Cursor, Amp, or Aider — and tired of maintaining two instruction files

Independent operator field guide, updated 2026-06-03. MIT-licensed prose. ~3,000 words.

Short answer: no — and the "fallback" claim you've seen is wrong

Tips

Mouse click lost after a while

The solution is to search and kill the processes named /usr/bin/VBoxClient --draganddrop

Search pgrep -a VBoxClient
Kill kill <pid> (or do both with tools like htop)

Shared clipboard lost after a while

The solution is to kill the current processes named /usr/bin/VBoxClient --clipboard and start a new one.

Search pgrep -a VBoxClient
Kill kill <pid> (or do both with tools like htop)

Avoiding CSS overrides in responsive components

I would like to demonstrate some of the benefits of scoped styles over mobile-first CSS with overrides for wider breakpoints. I'll start by explaining the two approaches, before listing the benefits.

Mobile-first with overrides for wider breakpoints

h2 {
  color: black;
 font-size: 2em;

Given a subscribed calendar with a url like

https://example.com/example.ics

To force Google Calendar to refresh and reload the contents right now, unsubscribe from the calendar and subscribe to a new calendar with a URL like

https://example.com/example.ics#1

Adding the anchor tag will force Google Calendar to think of it as a new calendar

This script for Google Spreadsheets allows you to generate slugs for your data such as might be used for creating unique urls.

Use it like this!

#	A	B	C
1	a	b	slug
2	foo	baz bing	=slugify(A2:B4)
3	bar	BAZ
4	FOO	baz-bing

The command line, in short…

wget -k -K -E -r -l 10 -p -N -F --restrict-file-names=windows -nH http://website.com/

…and the options explained

-k : convert links to relative
-K : keep an original versions of files without the conversions made by wget
-E : rename html files to .html (if they don’t already have an htm(l) extension)
-r : recursive… of course we want to make a recursive copy
-l 10 : the maximum level of recursion. if you have a really big website you may need to put a higher number, but 10 levels should be enough.
