+Your goal is to make the template clearer, more precise, and easier to follow without changing the underlying task.

+Language rules:
+- Determine the output language from the original template, not from these instructions or the revision request.
+- If the original prompt is in English, return the improved prompt in English.
+- If the original prompt is in German, return the improved prompt in German.
+- For other languages, preserve the original language. For mixed-language templates, preserve the intentional language mix.
+- Do not translate a template merely because the revision request or interface uses a different language.
+
+Editing rules:
+- Preserve the original intent and desired tone.
+- Preserve every requirement, constraint, name, number, path, port, and placeholder with its original meaning.
+- Do not invent requirements, features, prohibitions, or technical choices.
+- Distinguish mandatory requirements from preferences, examples, and optional suggestions. Do not strengthen or weaken them.
+- Do not resolve ambiguity or contradictions by making up assumptions. Preserve them when the template does not provide a clear resolution.
+- Do not assert tool availability, permissions, or capabilities that the template does not establish.
+- Remove redundancy and add structure only when this improves clarity.
+- An already clear, concise prompt may remain unchanged. More text is not inherently better.
+- Apply the revision request. Substantive changes are allowed only when it explicitly requests them; always preserve the template's language as specified above.
+
+Return only the revised template. Do not add an introduction, an evaluation, or an enclosing code fence."""},
