Overview
Constrain and normalize the assistant’s output formatting to match WhatsApp’s native styling syntax (single * for bold, _ for italics, ~ for strikethrough, ``` for monospace, etc.) while prohibiting unsupported Markdown constructs (headers, tables, HRs) so users never see raw Markdown artifacts in WhatsApp chats.
Key Advantages
1.Ensures messages render correctly in WhatsApp by using its native formatting primitives instead of generic Markdown.
2.Reduces visual noise and “raw symbol” leakage (e.g., **, #, |) that often appears when standard Markdown is sent directly to WhatsApp.
3.Promotes a clean, mobile-first reading experience by discouraging heavy formatting, headers, and tables in favor of simple text and lists.
4.Provides clear, explicit rules that are easy for the underlying model to follow, improving consistency across responses.
5.Useful as a guardrail skill in multi-channel bots where other skills or defaults assume full Markdown but WhatsApp does not.
Use Cases
- Customer support or sales assistants whose responses are delivered via WhatsApp and must look native to the platform.
- Multi-channel chatbots where a WhatsApp-specific formatter is needed to adapt generic Markdown responses to WhatsApp-safe syntax.
- Notification or alerting systems (order updates, status messages, reminders) that should remain readable and uncluttered in WhatsApp threads.
- Technical assistants sending short code snippets, IDs, or tokens via WhatsApp using monospace formatting without leaking backticks or other artifacts.
- Knowledge-base or FAQ bots that must avoid Markdown tables and headers, instead presenting information as simple bullet or numbered lists within WhatsApp.

OS: win32-x64LLM: google/gemini-3.1-pro-preview
Solid, focused formatting skill that aligns output with WhatsApp’s limited styling capabilities, preventing common issues like raw **markdown** symbols and broken headers. It is best used as a presentation-layer guardrail in any assistant whose replies are sent to WhatsApp, especially in multi-channel setups where other skills may expect full Markdown. Main risks are over-constraining formatting (no headers, no tables) and potential conflicts with other Markdown-centric skills or templates; also, it does not address all nuanced WhatsApp behaviors (e.g., how underscores interact with certain characters or links). Overall, it is a strong fit for production WhatsApp bots that value clean, human-readable, mobile-first messages over rich document-style layouts.

OS: win32-x64LLM: z-ai/glm-5
Quick judgment: Strong, focused formatting skill for WhatsApp, especially valuable in production WhatsApp bots where raw markdown artifacts are unacceptable. It strictly enforces WhatsApp’s native syntax (single * for bold, _ for italics, ~ for strikethrough, ``` for monospace, simple lists, and quotes) and explicitly bans headers, tables, and complex markdown, which matches WhatsApp’s real rendering behavior.
Main benefits:
- Great as a “presentation layer” skill when your assistant is deployed over WhatsApp.
- Reduces visual clutter and markdown noise for mobile-first users.
- Predictable, low-overhead behavior that composes well with other skills.
Risks / limitations:
- Not suitable for channels that rely on standard markdown (web, email, docs); using it there would remove useful formatting features like headers and tables.
- The prohibition on headers and tables can be constraining for dense, structured content; lists may become long and harder to scan.
- Monospace via ``` may still look slightly inconsistent across clients, and long code blocks won’t be handled richly (no syntax highlighting, no multi-line formatting control beyond WhatsApp’s default).
Recommended scenarios:
- WhatsApp-focused assistants (customer support, commerce, notifications) where reliability of appearance matters more than rich formatting.
- Multi-channel bots that switch styles per channel: use this specifically in the WhatsApp routing path.
- Teams standardizing message style guidelines for WhatsApp agents and bots to keep a consistent “Human-to-Human” look.
