DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

 A custom skill is a directory containing a `SKILL.md` file plus any supporting files, uploaded to your workspace as a zip archive or as individual files. Creating the skill returns the `skill_*` ID you reference when attaching it to an agent. Anthropic pre-built skills are already available in every workspace and don't require this step. To use only pre-built skills, skip to [Attach skills to an agent](https://platform.claude.com/docs/en/managed-agents/skills#attach-skills-to-an-agent).
 
-When you call the Skills API directly with cURL, pass the `anthropic-beta: skills-2025-10-02` header explicitly. The CLI and SDKs send it automatically.
+The Skills API doesn't require a beta header. The cURL example still sends `anthropic-beta: skills-2025-10-02`, and the CLI and SDK `beta` commands add it automatically; requests that include it continue to work unchanged.
 
 These examples omit the optional `display_title` field, so the skill's title is derived from `SKILL.md`. An explicitly passed `display_title` must be unique among the custom skills in your workspace.
