Business Requirements (BRD) — Introduction

Document Purpose​

This document defines the high-level business requirements, scope, and objectives for the Fast Layered Universal Document Engine (Flude). It serves as the primary agreement between stakeholders and the development team.

Business Objectives​

The primary objective of Flude is to automate and streamline the generation of modern, high-aesthetic, and high-performance developer portals and API references. It separates raw code from user-facing manuals while keeping them structurally aligned in production.

To ensure business viability, Flude must meet the following measurable success criteria:

  • High-Speed Execution (Performance Metric): The compiler and renderer must process raw API inputs and compile them into formatted output documentation in less than 5 seconds on standard CI/CD runner instances for a benchmark volume of up to 10,000 API entities (classes, methods, functions, enums) distributed across 1,000 source entities (approx. 10 MB of raw parsed inputs), minimizing developer feedback cycles.
  • 100% Git Hygiene (Zero-Pollution Metric): Achieve zero-pollution of source repositories by executing reference generation "on-the-fly" in the build pipeline, ensuring that absolutely zero generated files (including Markdown, HTML, XML, JSON, or temporary assets) are checked into Git.
  • AI-Powered Documentation Enrichment (Enrichment Metric): Automatically identify undocumented or sparsely documented public API entities and generate high-quality docstring drafts using LLMs, providing a dedicated review/export format to enable 100% human-approved documentation expansion.
  • Zero-Effort Multilingual Delivery (Localization Metric): Automatically translate and localize prose across multiple locales in CI/CD using AI translation middleware, achieving 0% developer translation overhead while employing an incremental translation cache and human override schemas to preserve manual corrections.
  • Enterprise AI Integration (RAG Ingestion Metric): Produce structured, semantic-dense schemas (such as RAG JSON) where 100% of parsed API classes and methods are correctly mapped with rich metadata for immediate ingestion into vector databases.
  • Execution & Cost Reporting (Build Reporting Metric): Automatically generate comprehensive build reports detailing processing times, file counts, translation cache efficiency, and precise LLM token usage/costs for each CI/CD execution.
  • Documentation Coverage Audit (Coverage Metric): Quantify the documentation status of the entire codebase by generating detailed coverage reports (aiming for >90% documentation coverage of all public API entities) with customizable quality gates that can fail the CI/CD pipeline if coverage drops below the defined threshold.
  • Enterprise-Grade Data Safety (Security Compliance): Guarantee 100% protection of intellectual property by utilizing enterprise cloud endpoints (e.g., Google Cloud Vertex AI) governed by strict NDAs/SLAs, ensuring no source code, docstrings, or prompts are stored, logged, or used for model training.
  • Zero-Manual Action Pipeline (Automation Metric): Ensure 100% hands-free pipeline execution with zero mandatory manual interactions for regular builds, offering native integrations with CI/CD platforms for scheduled and event-driven automation.
