2121You invoke a bundled skill the same way as any other skill, by typing `/` followed by the skill name. Claude invokes some bundled skills automatically when relevant; others, including `/verify`, run only when you invoke them, which keeps you in control of when these longer-running checks spend time and tokens.

23Bundled skills are available in every session. To turn them off, use the [`disableBundledSkills`](/docs/en/settings-reference#disablebundledskills) setting, which disables every bundled skill except `/doctor`.
23Most bundled skills are available in every session. A few depend on a specific feature: `/workflow-authoring`, for example, is available only when [dynamic workflows](/docs/en/workflows) are enabled.

2628 The [`/doctor`](/docs/en/commands#all-commands) setup checkup stays typable when `disableBundledSkills` is on, in Claude Code v2.1.205 and later. To hide it, set the `DISABLE_DOCTOR_COMMAND` environment variable or a [`skillOverrides`](#override-skill-visibility-from-settings) entry of `"doctor": "off"`. Before v2.1.205, `/doctor` was a built-in command rather than a bundled skill.

322324All fields are optional. Only `description` is recommended so Claude knows when to use the skill.

326Claude Code reads the frontmatter only when the opening `---` is the file's first line. Otherwise it treats the whole file, `---` markers included, as skill content.

324328Boolean fields accept `yes`, `no`, `on`, `off`, `1`, and `0` in any letter case, in addition to `true` and `false`. Before v2.1.218, Claude Code recognized only `true` and `false`.
