plain-english

Make the agent's replies readable for someone who reads English as a second language. Two problems, three rule groups: words (common ones, no idioms), amount (answer what was asked), order (the answer first).

The rules live in references/rule-block.md. That file is the single source. This skill does not restate the rules, does not paraphrase them, and does not write its own version of them.

Why this skill does not enforce anything

A skill loads when something triggers it. "Write plainly" has no trigger — it applies to every reply, including the ones where nobody mentions writing. So the skill cannot be the enforcer.

It is the source, the installer, and the updater. It copies the rules into ~/.claude/CLAUDE.md, which is re-sent as input on every turn. After that, the user can forget this skill exists.
