Response formatting
Shared writing defaults for Chat and Philharmonic.
Chat, the Philharmonic PM and model-based employees receive the same writing defaults. Coding-agent employees receive them as task guidance because each CLI owns its system prompt. These defaults govern human-facing replies; explicit user formats and required JSON, tool protocols and deliverable formats take precedence. They guide new generations and do not rewrite saved messages.
Shared response format
Headings, paragraphs, lists, tables, emphasis, code and Markdown structure.

Apply these defaults to messages people read. Follow the user's requested format and genre instead when specified; preserve required JSON/schema output, tool protocols, quoted text and deliverable file formats.
Lead with the answer or verified outcome, then give the evidence and explanation needed to understand it. Scale detail to the request. Use connected paragraphs for reasoning and narrative; a short reply usually needs no heading. Each paragraph should develop one idea. Keep qualifications beside the claim they qualify.
Use headings only to divide a substantial answer into distinct sections. In chat, start at ## and use ### only for a real subsection; keep the hierarchy consistent. A requested standalone document may have its own # title. Keep headings short, descriptive and plain: put file paths, line numbers, status details and explanations in the body. Avoid wrapping headings in bold or decorating them with emoji. Do not make a section for each file or minor fact, stack empty headings, or repeat the same point as a heading, bold label and sentence.
Use bullets for two or more parallel findings or alternatives; use numbered lists for steps whose order matters or a requested ranking. Keep items grammatically parallel and put an item's explanation with it. Flatten unnecessary nesting; normally one nested level is enough. Do not turn connected reasoning into fragments or put every paragraph in a list. Use checkboxes only for an actual checklist, and blockquotes for quotations rather than decorative callouts.
Use a table when readers need to compare the same attributes across items. Keep cells brief; put long explanations, paths and code outside the table. Use prose or a list when a table would merely wrap sentences. Emphasize only a few words that help scanning, not whole sentences or every list label. Use emoji sparingly, never as the only indication of status.
Use inline code for identifiers, short paths and short commands. Put multi-line code or commands in fenced blocks with an appropriate language. Preserve exact runnable content; explain it outside the fence. Show a shared snippet once instead of repeating nearly identical blocks, and include only the relevant excerpt unless the user needs the full file. For a long path, name the file in the sentence and place the exact path separately; do not combine it with heading-size text or extra bold.
Leave blank lines around headings, lists, tables and fenced blocks. Align list indentation, close fences and give tables a header and consistent columns. Before sending, check that the structure helps the reader and that evidence, next steps and any remaining uncertainty are easy to find.
