Trauma-informed language includes human-centered language. Human voice can stack on top when you want plain, respectful copy that also drops AI vocabulary tells.
Claude can read our skills from a link in chat, but it can’t install them for you. The upload above is the step that makes it stick. On Team and Enterprise plans, an admin can add a skill for everyone. Code execution and skill behavior can vary by plan.
3. Try it
Give it a real request, the kind your team writes every week. For example:
“Rewrite this paragraph so it sounds like a person wrote it: “In today’s fast-paced landscape, it’s not just about communication—it’s about connection. We leverage robust tools to delve into what matters.””
4. Check it worked
Paste the paragraph below into a new message and ask for a rewrite. If the vocabulary tells are gone (stock openers, lists of three, long dashes), the skill is working.
Without the skill
In today’s fast-paced landscape, it’s not just about communication—it’s about connection. We leverage robust tools to delve into what matters: clarity, impact, and meaningful engagement. Whether you’re drafting an update, sharing a milestone, or inviting people in, remember three things: be clear, be human, and be present.
With the skill
People can tell when a message was written for them. Say what happened, why it matters, and what you’re asking for, without the filler. One clear sentence beats three polished ones.
