Agent skill sync with docs: className, MDX code, CLI flags

[mintlify]

Summary

Sync the canonical Mintlify agent skill with authoritative English documentation changes from 2026-09-08/09.

Changes

• reference/components.md: add "Styling with className" section (all built-in components except Banner, MDX, and Visibility accept className; Tailwind arbitrary values work; class names must be written in full; Tab className targets the content panel), note inline Markdown support in title props, and document code behavior inside <MDX> fragments.
• reference/configuration.md: replace the outdated claim that Tailwind arbitrary values are unsupported and that inline style should be used instead; now documents arbitrary values, variants, className support, and advises against the style prop.
• reference/cli.md: --groups is space-separated (not comma-separated) on mint dev/validate/export; telemetry is no longer described as anonymous (logged-in events include the account email); note the npm package is mint, not the legacy mintlify package.

Context

Driven by docs commits: 6c53a28 (className and Tailwind arbitrary value support), 8774f9e (code inside MDX fragments), eed7384 (--groups flag fix), 2d3252c (CLI telemetry email attribution), a55aea9 (mint npm package clarification).

Validation: npm test, npm run check, npm run build, and git diff --check all passed. The existing sync workflow will distribute the canonical skill to plugin repositories after merge.

Note

Low Risk
Documentation-only updates to agent skill reference files; no application or runtime behavior changes.

Overview
Updates the canonical Mintlify agent skill reference docs to match recent English product documentation.

Components & styling: Adds guidance on className (Tailwind v3, arbitrary values, full literal class names, Tab panel vs label), inline Markdown in component title props, and how code fences/escaping work inside <MDX> fragments.

Configuration: Replaces outdated styling guidance—Tailwind arbitrary values and variants are supported, components accept className, and inline style is discouraged—so agents no longer recommend the wrong approach.

CLI: Documents space-separated --groups on dev/validate/export, clarifies telemetry (not blanket “anonymous”; logged-in usage can include account email), and states the npm package is mint, not legacy mintlify.
