Best practices for writing email content that avoids spam filters and gets read. Load this skill whenever writing or reviewing any email from scratch - content decisions affect deliverability just as much as authentication does. Use it for: composing subject lines, preview text, HTML email structure, body copy, CTAs, plain-text alternatives, image guidelines, link rules, or auditing an email for spam signals. Also load it when a user asks why a specific email feels spammy, what words to avoid, how to structure an HTML email, or how to write a CTA. Covers both transactional and marketing content.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
Show its rules and text
We split this skill into the rules it gives an agent
44 rules. 0 are common, 33 are distinctive, and 11 are very specific to this project.
0
Common
Most of the 18 edited versions we read keep these.
33
Distinctive
This author's own choices. Worth a look.
11
Very specific
Tied to their project's names, files or tools. Probably skip.
No licence file, so all rights are reserved — read it at the source. We count its rules but don't quote them. Read them on GitHub.
“Common” is measured: kept by at least 6 in 10 of the 18 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
