# RPG-MCP Build Diary This document serves as the master index for the development of the RPG-MCP Server. It chronicles the journey from initial concept to a fully packaged, production-ready system. ## 1. The Master Plan - **[Task Map](diary/TASK_MAP.md)**: The comprehensive checklist that guided the entire development process. Tracks every feature from World Generation to Packaging. - **[Math Engine Task Map](diary/MATH_TASK_MAP.md)**: Detailed roadmap for the Math Engine implementation (9 phases, all complete). ## 2. Development Progress - **[World Generation Progress](diary/WORLDGEN_PROGRESS.md)**: Detailed log of the procedural generation algorithms, including Perlin noise implementation, river generation, and biome mapping. - **[Walkthrough](diary/WALKTHROUGH.md)**: A guide to the implemented features, including usage examples for all MCP tools (World, Combat, Spatial). ## 3. New Systems (2025-11) ### Inventory System ✅ - Item templates with weight, value, and properties - Character inventories with stacking and equipment slots - Full CRUD operations via MCP tools - Tests: All passing ### Quest System ✅ - Quest creation with objectives, rewards, prerequisites - Quest assignment and progress tracking - Quest completion with automatic reward distribution - Tests: All passing ### Math Engine ✅ **COMPLETE** - **5 Specialized Engines**: Dice, Probability, Algebra, Physics, Export - **Deterministic Dice Rolling**: Seeded RNG for reproducible results - **Probability Calculations**: Full distributions, expected values, comparisons - **Symbolic Algebra**: Equation solving, simplification, calculus - **Physics Simulations**: Projectile motion, kinematics (SUVAT) - **Multi-Format Export**: LaTeX, MathML, plaintext, step-by-step - **Full Persistence**: Calculation history with event logging - **5 MCP Tools**: dice_roll, probability_calculate, algebra_solve, algebra_simplify, physics_projectile - Tests: 5/5 integration tests passing - Documentation: [Math Engine Walkthrough](diary/MATH_ENGINE_WALKTHROUGH.md) ## 4. Technical Challenges & Reflections - **[Reflection: Event Streaming & Auditing](diary/REFLECTION.md)**: A deep dive into the implementation of the Event System and Audit Logging. Discusses architecture decisions, testing strategies, and lessons learned. - **[Vitest Issue](technical/VITEST_ISSUE.md)**: Documentation of a specific technical hurdle encountered with the test runner and how it was resolved. - **[Math Engine Development](../MATH_TASK_MAP.md)**: 9-phase implementation covering schemas, engines, persistence, and MCP integration. ## 5. Final Status ### Completed Systems - ✅ World Generation (procedural terrain, biomes, rivers) - ✅ Combat Engine (attack rolls, damage, saving throws, encounter balance) - ✅ Spatial Reasoning (pathfinding, line-of-sight, collision detection) - ✅ Inventory System (items, equipment, stacking) - ✅ Quest System (objectives, rewards, progress tracking) - ✅ **Math Engine** (dice, probability, algebra, physics, calculus) - ✅ Event System (PubSub, audit logging, replay capability) - ✅ Persistence (SQLite, migrations, repositories) ### Build Status - **Tests**: All passing (Math: 5/5, Inventory, Quest, Core systems) - **TypeScript Build**: ✅ Passing (all lint errors resolved) - **CI/CD**: Active and monitoring - **Packaging**: Cross-platform binaries available ### Remaining Work (from TASK_MAP.md) Based on the main task map, there are still some items pending in Phase 1 (Critical Fixes) and beyond related to multi-tenancy and state management improvements. --- *Last updated: 2025-11-28*
