+When the environment variable `BMAD_STYLE=prose` is set, apply this repository's formatting policy:
 
-1. Write sections in full sentences and paragraphs. Avoid shorthand.
-2. Do not use terse bullet-only outputs unless identifiers are mandatory (e.g., FR/NFR numbers). When lists are necessary, convert each item into 1-2 descriptive sentences.
-3. Always cover, in order where applicable: Purpose → Structure → Behavior → Conditions → Results → Errors/Edge Cases → Accessibility/Non-Functional → Acceptance.
-4. Replace ambiguous shorthand with explicit phrasing. Example: “1行省略” → “1行表示領域を超えたテキストは末尾に省略記号（…）を付けて切り詰める”。
-5. Prefer paragraph explanations before any diagrams or tables to clarify context and rationale.
+1. Write in full sentences, but format output as one sentence per line, and prefix each sentence with `* ` (asterisk + space).
+2. Do not wrap multiple sentences into a single paragraph. Each sentence must be its own bullet line for readability and diffability.
