Summary

PromptMN is a pseudo-prompting domain-specific language designed to enhance human-generative AI interaction by addressing the fragility of natural language prompts. It annotates natural language with compact, %-prefixed typed directives covering roles, goals, requirements, priorities, constraints, plans, inputs, and outputs. This structured approach allows authors to write in any order while the model interprets directives by function, bridging the gap between informal prompting and programming-style pseudocode. PromptMN makes prompts inspectable and reusable for analysts, managers, and developers across the software development lifecycle (SDLC). The language also facilitates reverse prompt engineering, enabling users to inspect inferred roles and constraints before action. Its feasibility was successfully evaluated on frontier models, including Claude Fable 5, Claude Opus 4.8, Gemini 3.1 Pro, and GPT-5.5, which resolved complex structures like repetition and conditionals without fine-tuning, demonstrating its practical applicability in SDLC scenarios.

Key takeaway

For AI Engineers designing agentic workflows or Software Engineers integrating generative AI, adopting PromptMN can significantly reduce prompt ambiguity and subsequent repair cycles. By structuring your prompts with %-prefixed directives for roles, goals, and constraints, you gain inspectability and reusability, mitigating failures stemming from context misinterpretations. Consider implementing PromptMN to standardize prompt creation, especially when aligning multiple stakeholders or performing reverse prompt engineering to validate AI's understanding of desired outcomes.

Key insights

PromptMN is a pseudo-prompting language that adds structured, typed directives to natural language prompts, improving clarity and reusability.

Principles

• Natural language prompts are often fragile due to ambiguity.
• Structured directives improve AI interpretation and reduce failures.
• Reverse prompt engineering aids alignment and identifies assumptions.

Method

PromptMN annotates natural language with %-prefixed typed directives (e.g., %role, %goal) for semantic resolution, allowing flexible authoring while ensuring functional interpretation by AI models.

In practice

• Use %-prefixed directives for roles, goals, constraints.
• Employ reverse prompt engineering to inspect AI interpretations.
• Apply PromptMN across SDLC for consistent prompt structures.
