Improves clarity, structure, and tone of technical writing (docs, proposals, PR descriptions, commit messages, client-facing write-ups) for a junior-friendly, easy-to-understand audience, choosing German or English as appropriate. Informs rather than sells — no self-praise or reassurance. Applies this plugin's default voice to client-facing text and a plain, factual voice to engineering text, unless the project or an explicit request specifies otherwise. Not for authoring a skill's own SKILL.md content — see skill-writing for that. Use whenever writing or editing technical prose.
