What "Grounded AI" Actually Means (and Why It Matters for Your Documents)
Grounded AI means every answer comes from your documents, not the model’s memory. What grounding really is, how to test it, and where it falls short.

Spaghetti Table Protocol: Quick AI Physical-Grounding Test
The article introduces the Spaghetti Table Protocol, a 15-minute diagnostic stress test designers can run to reveal physical-grounding failures in multimodal generative AI. A pilot administered in Feb–Mar 2026 tested three leading multimodal models on an image prompt asking for a dining table with four dry-spaghetti legs, a concrete slab tabletop, and a fishbowl; an aggregate score across fifteen outputs was 4/30 (≈13%). The study found consistent structural failures across models: fluent photorealistic outputs that violate basic physics, session-contamination between prompts, and cases where symbolic acknowledgement of impossibility did not prevent an incoherent generation. The author shares a rubric, protocol specification, and a GitHub repo to crowdsource replication and build a public dataset, and invites designers to design domain-specific high-entropy stress tests to map where current architectures lack embodied physical reasoning.
Documenting AI 'Wrong Answers' Prevents Harmful Fixes
An engineer describes operational failures caused by AI agents that repeatedly propose plausible but incorrect fixes (e.g., replacing Enter with backslash+Enter, causing prompts not to send). Because each agent session has no memory, the author argues teams must record not only correct procedures but refuted hypotheses, dates, and provenance so future agent sessions won't reintroduce previously invalid fixes. Examples include agents misinterpreting a normal 302 redirect as an outage and a gating rule that anchored to a weaker reference agent (38% vs 78% vs 90.7% accuracy metrics). The author provides concrete documentation rules for running agents on real systems.
Most Developers Test Code — Why Not Test AI?
The article argues that AI features need the same rigorous testing workflows as traditional software. Developers commonly rely on informal manual checks for AI outputs (e.g., "I tried it three times and it seems pretty good"), but AI components (retrieval, prompts, LLMs, validation) can fail in many ways and are probabilistic. The author recommends building small evaluation datasets (20–50 representative test cases), testing prompts, context, and end-to-end workflows, and integrating evaluation into CI/GitHub workflows to measure whether changes (prompts, models, retrieval) actually improve performance. The piece presents a three-layer evaluation rule—produce an answer, produce correct answers consistently, and be able to measure improvement—and calls for treating evaluation as a first-class engineering concern.
