# PRD: Comprehensive Documentation Testing Mechanism **Created**: 2025-07-19 **Status**: Complete **Owner**: Viktor Farcic **Last Updated**: 2025-07-22 ## Executive Summary AI-powered documentation validation system that automatically executes commands, tests examples, and validates claims in documentation files to ensure accuracy and prevent documentation drift. ## Problem Statement Documentation frequently becomes outdated and unreliable due to: - Commands that no longer work as described - Code examples that fail when users try them - Instructions that skip crucial setup steps - Claims about software behavior that become inaccurate over time - Manual testing processes that are time-consuming and error-prone This leads to user frustration, reduced adoption, and loss of credibility for documentation. ## Interface Requirements This system provides MCP interface for AI agent integration: - **MCP Interface**: Model Context Protocol server for AI agent integration via tools like Claude Code, Cursor, VS Code All functionality, workflows, and capabilities are accessible through the MCP interface. ## Proposed Solution Comprehensive AI-driven testing system that: - Automatically discovers and categorizes testable content in documentation - Executes commands and examples in safe, isolated environments - Validates both functional accuracy (does it work?) and semantic accuracy (are the descriptions truthful?) - Provides structured feedback with actionable improvement recommendations - Supports resumable, session-based workflows for large documentation sets - Maintains detailed audit trails of testing results and changes ## User Stories & Use Cases - As a **documentation maintainer**, I want automated validation of all examples so that I can catch outdated content before users encounter it - As a **development team member**, I want documentation testing integrated into CI/CD so that code changes don't break documented examples - As a **technical writer**, I want to understand which sections need updates so that I can prioritize my work effectively - As a **open source maintainer**, I want confidence that my README and docs work for new contributors so that onboarding is smooth - As a **product manager**, I want metrics on documentation quality so that I can track improvements over time ## Requirements Tracking ### Functional Requirements - [x] **Session-based workflow management** -

**pending**: Not yet addressed - **fixed**: Completed (any type of resolution) - **deferred**: Handled via external action (GitHub issue, backlog) - removed from future sessions - **failed**: Attempted but couldn't complete - remains available for retry ### Development Tasks ✅ **COMPLETED** - [x] Core validation workflow implementation - [x] Section discovery and management - [x] Result processing and storage - [x] Automatic workflow progression logic -

[x] Create robust session state management with recovery capabilities - [ ] Develop performance monitoring and optimization strategies - [ ] Establish quality metrics for AI analysis effectiveness ## Decision Log ### Open Questions - [ ] **Fix Application Scope**: Should fix application be automatic, user-guided, or user-selected? | **Target**: Phase 4 kickoff - [ ] **CI/CD Integration Approach**: What's the best way to integrate with existing development workflows? | **Target**: Phase 4 planning ### Resolved Decisions - [x] **Two-Phase Validation Approach** - **Decided**: 2025-07-19 **Rationale**: Functional testing alone missed semantic accuracy issues; combined approach provides comprehensive validation - [x] **JSON Result Format** - **Decided**: 2025-07-19 **Rationale**: Structured data enables better analysis and processing in later phases compared to free-form text - [x] **Automatic Workflow Progression** - **Decided**: 2025-07-19 **Rationale**: Manual CLI calls between sections created friction; automatic progression improves user experience - [x] **File-based Prompt System** - **Decided**: 2025-07-18 **Rationale**: Separates AI instructions from code, enables easier prompt iteration and collaboration - [x] **Simplified 4-Phase Workflow** - **Decided**: 2025-07-19 **Rationale**: SCAN → TEST → ANALYZE → FIX approach with document-level coherence analysis and user-driven fix selection is simpler and more practical than complex coordination systems - [x] **Eliminate Document Coherence Analysis** - **Decided**: 2025-07-20 **Rationale**: Analysis of existing TEST phase revealed comprehensive functional and semantic validation already occurring (difficulty claims, automation claims, user experience validation, etc.), making additional document-level analysis redundant - [x] **Focus on Fix Application Only** - **Decided**: 2025-07-20 **Rationale**: TEST phase provides comprehensive issue identification and recommendations; users need way to select and apply fixes rather than additional analysis - [x] **Remove Workflow Selection** - **Decided**: 2025-07-20 **Rationale**: Simplified approach - users run documentation testing and get fix recommendations, no need for mode selection complexity - [x] **Trackable Item Data Structure** - **Decided**: 2025-07-20 **Rationale**: Convert issues and recommendations from string arrays to objects with id, text, status, and explanation fields for comprehensive fix tracking - [x] **Four-Status Fix Tracking** - **Decided**: 2025-07-20 **Rationale**: Use pending/fixed/deferred/failed status system where deferred items (handled via GitHub issues, backlog, etc.) are considered resolved and removed from future sessions - [x] **Client-Agent Fix Application** - **Decided**: 2025-07-20 **Rationale**: Client agent and user determine how to handle each recommendation (doc edit, code fix, external issue), system provides tracking and numbered list interface - [x] **Simple Sequential Fix IDs** - **Decided**: 2025-07-20 **Rationale**: Use simple numbering (1,2,3,4) rather than section-based IDs (2.1, 4.3) for easier user selection and reduced cognitive load - [x] **Move Phase 5 to Separate PRD** - **Decided**: 2025-07-22 **Rationale**: Recursive documentation testing represents substantial core functionality deserving dedicated PRD for proper tracking and planning, allowing PRD 12 to achieve completion - [x] **PRD 12 Scope Completion** - **Decided**: 2025-07-22 **Rationale**: With Phase 5 moved to separate PRD and build errors resolved, all single-document testing functionality is complete and functional ## Scope Management ### In Scope (Current Version) - [x] Single document validation with section-by-section processing - [x] MCP interface with complete feature set - [x] Session-based workflow management with resumption capabilities - [x] Two-phase validation (functional and semantic testing) -
