PromptL is a versatile, human-readable language that simplifies defining and managing dynamic prompts for LLMs. ## When to Apply Reference these guidelines when: - Writing new PromptL prompts for Latitude - Configuring LLM models and parameters - Using variables, conditionals, or loops in prompts - Creating multi-step chains or agentic workflows - Defining tools for function calling - Referencing other prompts (snippets) - Working with structured JSON output schemas ## Syntax Categories | Category | Purpose | Key Syntax | |----------|---------|------------| | Configuration | Define model, provider, and parameters | `---` YAML block | | Messages | Structure conversations | ``, ``, ``, `` | | Variables | Dynamic content | `{{ variable }}` | | Conditionals | Dynamic flow control | `{{ if }}`, `{{ else }}`, `{{ endif }}` | | Loops | Iterate over lists | `{{ for item in list }}`, `{{ endfor }}` | | Chains | Multi-step prompts | `` | | Tools | Function calling | `tools:` in config | | Agents | Autonomous workflows | `type: agent` | | Snippets | Reusable prompts | `` | | Content | Multi-modal content | ``, `` | ## Quick Reference ### Configuration Block ```yaml --- provider: OpenAI model: gpt-4o temperature: 0.7 top_p: 0.9 maxSteps: 20 --- ``` ### Message Tags - `` - System instructions - `` - User messages - `` - Assistant responses - `` - Tool interaction results - `` - Generic message tag ### Variables ``` {{ variable_name }} {{ variable || "default" }} {{ set myVar = "value" }} ``` ### Conditionals ``` {{ if condition }} content {{ else }} alternative {{ endif }} ``` ### Loops ``` {{ for item, index in items }} {{ index }}: {{ item }} {{ else }} No items {{ endfor }} ``` ### Chains (Multi-step) ``` First step content Use {{ result }} from previous step ``` ### Tools Configuration ```yaml tools: - tool_name: description: What the tool does parameters: type: object properties: param_name: type: string description: Parameter description required: - param_name ``` ### Agents ```yaml --- type: agent provider: OpenAI model: gpt-4o tools: - latitude/search agents: - agents/sub-agent-path maxSteps: 40 --- ``` ### Structured Output ```yaml schema: type: object properties: field_name: type: string description: Field description required: - field_name ``` ### Prompt References (Snippets) ``` ``` ### Content Types ``` Plain text
