Agent Skills: ring:applying-voice-and-tone

Applying the technical-writing voice and tone style guide: second person, present tense, active voice, short sentences, sentence-case headings, product/entity capitalization, contractions, and sparing emphasis. Use when checking voice/tone compliance, writing new docs, or reviewing docs for style. Skip when checking structure only (use ring:structuring-documentation) or technical accuracy only (use the docs-reviewer agent).
