System prompts are scripts that are executed and injected before the main prompt output. - `system.*.genai.js` are considered system prompt templates - system prompts are unlisted by default - system prompts must use the `system` instead of `script` - system prompts are executed with the same environment as the main prompt ```js title="system.zero_shot_cot.genai.js" "system" system({ title: "Zero-shot Chain of Thought", }) export default function (ctx: ChatGenerationContext) { const { $ } = ctx $`Let's think step by step.` } ``` :::caution System prompts must have a default function and use the `ctx` passed in the function. ::: To use system prompts in script, populate the `system` field with script identifiers. ```js title="myscript.genai.js" 'system: ["system.zero_shot_cot"]' script({ ..., system: ["system.zero_shot_cot"] }) $`Let's think step by step.` ``` It is also possible to populate system script by include tool names which will result in importing the tool into the script. ```js script({ ..., tools: ["math_eval"] }) ``` ## Parameters and variables System also support parameters as script but the parameter names will automatically be prepended with the script id - declare and use the parameter in the system script ```js title="system.fs_read_summary.genai.js" system({ ..., parameters: { model: { type: "string", description: "LLM model to use" }, }, }) export default function (ctx: ChatGenerationContext) { const { env } = ctx // populate from the default value or script override const model = env.vars["system.fs_read_summary.model"] } ``` - override the parameter value in the script script ```js script({ ..., system: ["system", "system.fs_read_summary"], vars: { "system.fs_read_summary.model": "ollama:phi3", }, }) ``` - override the parameter value in instance of the system script ```js script({ ..., system: [ "system", { id: "system.fs_read_summary", parameters: { model: "ollama:phi3" }, }], }) ``` ## Automated System Prompts When unspecified, GenAIScript inspects the source code of the script to determine a reasonable set of system prompts ([source code](https://github.com/microsoft/genaiscript/blob/main/packages/core/src/systems.ts)). The default mix is - system - system.output_markdown - system.explanations - system.safety_jailbreak - system.safety_harmful_content - system.safety_protected_material On top of the default, injects other system scripts based on keyword matching. ## Builtin System Prompts GenAIScript comes with a number of system prompt that support features like creating files, extracting diffs or generating annotations. If unspecified, GenAIScript looks for specific keywords to activate the various system prompts. ### `system` Base system prompt `````js wrap title="system" system({ title: "Base system prompt" }) export default function (ctx: ChatGenerationContext) { const { $ } = ctx $`You are concise, no yapping, no extra sentences, do not suggest to share thoughts or ask for more.` } ````` ### `system.agent_data` Agent that can query data in files `````js wrap title="system.agent_data" system({ description: "Agent that can query data in files", }) export default function (ctx: ChatGenerationContext) { const { defAgent } = ctx defAgent( "data", "query data from files", `You are an expert data scientist that can answer questions about data in files.

For complex prompts, enhance clarity and add missing elements without altering the original structure. - Reasoning Before Conclusions**: Encourage reasoning steps before any conclusions are reached. ATTENTION! If the user provides examples where the reasoning happens afterward, REVERSE the order! NEVER START EXAMPLES WITH CONCLUSIONS! - Reasoning Order: Call out reasoning portions of the prompt and conclusion parts (specific fields by name). For each, determine the ORDER in which this is done, and whether it needs to be reversed. - Conclusion, classifications, or results should ALWAYS appear last. - Examples: Include high-quality examples if helpful, using placeholders [in brackets] for complex elements. - What kinds of examples may need to be included, how many, and whether they are complex enough to benefit from placeholders. - Clarity and Conciseness: Use clear, specific language. Avoid unnecessary instructions or bland statements. - Formatting: Use markdown features for readability. - Preserve User Content: If the input task or prompt includes extensive guidelines or examples, preserve them entirely, or as closely as possible. If they are vague, consider breaking down into sub-steps. Keep any details, guidelines, examples, variables, or placeholders provided by the user. - Constants: DO include constants in the prompt, as they are not susceptible to prompt injection.
