.. _data-structure-design: Data Structure Design: Prompt & Test Data Organization ============================================================================== .. list-table:: :widths: 20 80 * - **Version** - v0.3 Draft * - **Date** - 2026-04-23 * - **Purpose** - Define the directory structure and file conventions for storing prompts, test data, and evaluation criteria across all use cases **and** judges. This document uses UC1 (Multi-Step Claim Intake Processing) and J1 (Over-Permissive Authorization Judge) as concrete examples. ---- Design Principles ------------------------------------------------------------------------------ 1. **TOML for structured test data** — TOML's native multiline string support (``"""..."""``) makes it ideal for storing narrative text alongside structured metadata. Python 3.11+ includes ``tomllib`` in the standard library; no external dependency needed. 2. **Jinja for prompt templates** — Prompt files use ``.jinja`` extension for template rendering. System prompt and user prompt are stored as separate files to mirror the Bedrock Converse API's ``system`` / ``messages`` separation, enabling prompt caching on the system prompt. 3. **Normal and attack test cases are separated** — ``normal/`` contains non-malicious inputs for correctness testing. ``attack/`` contains inputs with embedded malicious payloads for security testing. 4. **Explicit prompt versioning** — Each prompt version is a directory (``versions/01/``, ``versions/02/``, etc.) containing ``system-prompt.jinja``, ``user-prompt.jinja``, and ``metadata.toml``. This enables side-by-side comparison of risk profiles across prompt iterations. 5. **Test data lives with its prompt** — Each prompt directory has its own ``normal/`` and ``attack/`` test data. No shared data indirection unless a concrete cross-prompt reuse need arises. 6. **Per-use-case data schemas** — Each use case defines its own TOML schema appropriate to its architecture (pipeline, RAG, agent loop, etc.). No forced uniformity. 7. **Unified prompt structure for UC prompts and judges** — Both use-case prompts and judge prompts follow the same three-file convention (``system-prompt.jinja`` + ``user-prompt.jinja`` + ``metadata.toml``). Judges are themselves prompts — their templates accept target prompt text as input variables instead of business data. ---- Top-Level Directory Structure ------------------------------------------------------------------------------ The ``data/`` directory has two top-level branches: **use-case prompts** (``uc*``) and **judge prompts** (``judges/``). .. code-block:: text data/ ├── uc1-claim-intake/ # Use Case 1: Multi-Step Claim Intake │ ├── INDEX.md │ └── prompts/ │ ├── p1-extraction/ │ ├── p2-classification/ │ ├── p3-triage/ │ ├── p4-coverage-check/ │ └── p5-routing/ │ ├── uc2-underwriting-rag/ # Use Case 2: Underwriting Knowledge Assistant │ └── ... ├── uc3-commercial-risk/ # Use Case 3: Commercial Client Risk Profiling │ └── ... ├── uc4-litigation-support/ # Use Case 4: Litigation Support Agent │ └── ... ├── uc5-claims-automation/ # Use Case 5: Claims Automation Agent │ └── ... ├── uc6-policyholder-ai/ # Use Case 6: Policyholder Self-Service AI │ └── ... │ └── judges/ # Judge prompts (LLM-as-Judge evaluation) └── prompts/ ├── j1-over-permissive/ ├── j2-hardcoded-data/ ├── j3-role-confusion/ ├── j4-instruction-conflict/ └── j5-logic-ambiguity/ ---- Use-Case Prompt Structure ------------------------------------------------------------------------------ General Layout ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each use-case prompt follows the same internal structure: versioned prompt files plus test data. .. code-block:: text data/ uc1-claim-intake/ INDEX.md # Use case data overview prompts/ p1-extraction/ versions/ 01/ system-prompt.jinja # System prompt (Bedrock system parameter) user-prompt.jinja # User prompt template with {{ narrative }} metadata.toml # Version description and date 02/ # Next iteration ... normal/ # Non-malicious test inputs b-01-auto-rear-end.toml b-02-property-fire.toml b-03-workers-comp-fall.toml attack/ # Malicious test inputs a-01-injection-in-narrative.toml a-02-hidden-instructions.toml p2-classification/ versions/01/... normal/... attack/... p3-triage/ ... p4-coverage-check/ ... p5-routing/ ... Naming Conventions ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. list-table:: :header-rows: 1 :widths: 30 35 35 * - Element - Convention - Example * - Use case directory - ``uc{N}-{short-name}`` - ``uc1-claim-intake`` * - Prompt directory - ``p{N}-{function}`` - ``p1-extraction`` * - Prompt version directory - ``versions/{NN}/`` - ``versions/01/`` * - System prompt file - ``system-prompt.jinja`` - — * - User prompt file - ``user-prompt.jinja`` - — * - Version metadata - ``metadata.toml`` - — * - Normal test input - ``b-{NN}-{description}.toml`` - ``b-01-auto-rear-end.toml`` * - Attack test input - ``a-{NN}-{description}.toml`` - ``a-01-injection-in-narrative.toml`` ---- Judge Prompt Structure ------------------------------------------------------------------------------ General Layout ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Judge prompts live under ``data/judges/prompts/`` and follow the **same three-file convention** as use-case prompts. The key difference is in **what the templates receive as input**: judge prompts take target prompt text as Jinja variables, rather than business data like FNOL narratives. .. code-block:: text data/ judges/ prompts/ j1-over-permissive/ versions/ 01/ system-prompt.jinja # Judge's system prompt (role + criteria + output format) user-prompt.jinja # Template: injects {{ data.target_system_prompt }} etc. metadata.toml # Version description, judge category, date 02/ # Next iteration ... j2-hardcoded-data/ versions/01/... j3-role-confusion/ versions/01/... j4-instruction-conflict/ versions/01/... j5-logic-ambiguity/ versions/01/... Naming Conventions ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. list-table:: :header-rows: 1 :widths: 30 35 35 * - Element - Convention - Example * - Judge directory - ``j{N}-{short-name}`` - ``j1-over-permissive`` * - Version directory - ``versions/{NN}/`` - ``versions/01/`` * - System prompt file - ``system-prompt.jinja`` - — * - User prompt file - ``user-prompt.jinja`` - — * - Version metadata - ``metadata.toml`` - — How Judge Prompts Differ from UC Prompts ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Although the file structure is identical, the content and data flow differ: .. list-table:: :header-rows: 1 :widths: 20 40 40 * - Aspect - UC Prompt - Judge Prompt * - **system-prompt.jinja** - Defines the agent's role and behavior for a business task (e.g., "You are a claims intake specialist...") - Defines the judge's role and evaluation criteria (e.g., "You are a prompt security auditor specializing in Over-Permissive Authorization risk assessment...") * - **user-prompt.jinja** - Injects runtime business data via Jinja variables (e.g., ``{{ narrative }}``, ``{{ extracted_fields }}``) - Injects the **target prompt text** to be evaluated via Jinja variables (e.g., ``{{ data.target_system_prompt }}``, ``{{ data.target_user_prompt_template }}``) * - **metadata.toml** - Contains ``description`` and ``date`` - Contains ``description``, ``judge_category``, and ``date`` * - **Test data** - ``normal/`` and ``attack/`` TOML files alongside the prompt, containing business-domain inputs - No local test data; judges are tested by running them against UC prompts with **known-answer expectations** (see Document 06) Judge metadata.toml Example (J1) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ .. code-block:: toml description = "Evaluates a prompt for over-permissive authorization risks" judge_category = "over_permissive_authorization" date = 2026-04-23 Judge user-prompt.jinja Input Variables ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The judge's user prompt template accepts the target prompt under review as input. The key variables are: .. list-table:: :header-rows: 1 :widths: 35 65 * - Variable - Description * - ``data.target_system_prompt`` - The full text of the target UC prompt's ``system-prompt.jinja`` (rendered) * - ``data.target_user_prompt_template`` - The full text of the target UC prompt's ``user-prompt.jinja`` (optional; shown as a template so the judge can assess what data enters the LLM context) The judge's user prompt conditionally renders Part 1 (system prompt) and Part 2 (user prompt template) depending on whether a user prompt template was provided. ---- File Format Specifications ------------------------------------------------------------------------------ Prompt Files ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Each prompt version — whether UC or judge — is a directory containing three files: **system-prompt.jinja** — The system prompt sent via Bedrock Converse API's ``system`` parameter. This is fixed per request and benefits from prompt caching. .. code-block:: text You are a claims intake specialist. Given the following First Notice of Loss (FNOL) narrative, extract the structured fields listed below. Return your response as a JSON object with exactly these fields: ... **user-prompt.jinja** — The user message template.
