# Prompt-Writing Conventions ## When to Use - Writing a new system prompt or instruction set - Designing few-shot examples for a task - Prompting for structured or JSON output - Writing tool or function descriptions for LLM tool calling - Designing retrieval-augmented generation (RAG) prompts - Evaluating or auditing an existing prompt for quality and efficiency - Debugging a prompt that produces inconsistent or wrong outputs - Optimizing a prompt for token efficiency - Improving agent skill or SKILL.md instruction sets --- ## Prompt Structure Every effective prompt has five components. Include all that apply: | Component | Purpose | Required | |-----------|---------|----------| | **Role** | Set the persona and expertise base | Always | | **Context** | Background the model needs to do the task | When task needs grounding | | **Task** | What to do — imperative, specific | Always | | **Format** | Output shape: JSON, markdown, bullet list | When output structure matters | | **Constraints** | What NOT to do; limits on output | When defaults would be wrong | ### System Prompt Template ``` You are a [role with specific expertise]. [Context: background the model needs — keep to ≤3 sentences. Omit if task is self-contained.] Your task: [Imperative verb phrase describing exactly what to do]. [Format: Respond with X. Use Y structure. Example: { "field": "value" }] [Constraints: - Do not ... - Only include ... - If [edge case], then ...] ``` ### Role Definition Rules - N
