The approach, developed through trial-and-error with GraphRAG and MCP, uses harnesses to confine where errors can occur and targets 90% coverage for solo implementation.", "body_md": "Series Final. The four mechanisms covered across this series — knowledge graph, Auto Review, Self-Healing, Recurrence Prevention — plus the non-engineer-PR application that sits on top of them, all hang off a single conviction: AI isn't something to trust; it's something to design. The 'I don't trust AI to fill in the blanks for me' framing this lives inside isn't doubt about generation quality, but the clear-eyed acceptance that AI has no idea what context wasn't handed to it, and that 'ideal behavior with no spec given' is a fantasy. The starting point goes back to 2025, when I was trying to figure out how to make AI actually understand a large codebase — and ran into walls on both context window scaling (lost in the middle, attention dilution) and learning-based approaches (machine unlearning, destructive interference). GraphRAG + MCP became the way out: hand AI only the facts it needs, when it needs them, so it doesn't have to infer. From code-graph (which I burned two months on and threw away) to the current product-graph (cpg). This piece is the philosophy and the trial-and-error behind the whole series: harnesses confine where hallucinations are allowed to happen, design is translating principles into your own use cases, and Coverage 90% as a solo target breaks the implementation.", "url": "https://wpnews.pro/news/ai-isn-t-something-to-trust-it-s-something-to-design", "canonical_source": "https://ryantsuji.dev/posts/cortex-philosophy", "published_at": "2026-06-16 00:00:00+00:00", "updated_at": "2026-07-15 23:59:39.250207+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-tools", "ai-infrastructure", "ai-research"], "entities": ["GraphRAG", "MCP"], "alternates": {"html": "https://wpnews.pro/news/ai-isn-t-something-to-trust-it-s-something-to-design", "markdown": "https://wpnews.pro/news/ai-isn-t-something-to-trust-it-s-something-to-design.md", "text": "https://wpnews.pro/news/ai-isn-t-something-to-trust-it-s-something-to-design.txt", "jsonld": "https://wpnews.pro/news/ai-isn-t-something-to-trust-it-s-something-to-design.jsonld"}}
