How to Use This Knowledge Base

Read an area overview first when learning a topic from scratch. Use concept pages for quick reference. Follow related-concept links when a decision crosses boundaries between product shaping, AI behaviour, software quality and agent-assisted implementation.

Each concept page follows a compact template: definition, why it matters, engineering mode, evaluation check, real example, related concepts and source note. Short concepts stay concise rather than being padded with generic prose.

The site’s organising structure follows Andrew Ng’s AI Engineering Skills Map, published by DeepLearning.AI in The Batch. Ng’s map is the primary source for the four areas. Area 1 follows Ng’s more detailed writing; Areas 2-4 are this site’s reasoned extension.
