Why AI Data Agents Still Fail at Real Company Data (Medium)
Summary: A new benchmark for AI data agents reveals a significant gap between the promise of natural-language business analytics and current performance. The DAB benchmark tests agents on messy, multi-database, real-world queries, where the best model achieves only a 38% success rate on its first attempt. Even with 50 retries, accuracy peaks below 70%, highlighting that the core challenge is not understanding the question but correctly executing the analysis on imperfect data.

Why it matters: For operators and analysts considering AI tools, this benchmark shifts the conversation from demos to operational risk, clarifying that the current value proposition is assistant-level, not autonomous.
Context: The AI data agent space has been dominated by smooth demos on clean datasets, creating expectations for a ‘no-SQL’ future. This research provides a concrete, adversarial test against the complexity of actual business data environments.
"Why AI Data Agents Still Fail at Real Company Data A new benchmark shows that asking questions in plain English is easy. Getting the right answer from messy business data is still." — MEDIUM
Commentary: The benchmark usefully reframes the problem: the failure mode is not bad SQL but flawed analytical reasoning, producing polished, plausible wrong answers. This forces a near-term product shift from ‘AI analyst’ to ‘assistant with automated checks,’ prioritizing verifiability over confidence. The cost-accuracy tradeoff, where the most accurate model is 20x more expensive, will shape commercial adoption, favoring layered systems that embed human review for high-stakes decisions.

Running Python code in a sandbox with MicroPython and WASM (Simonwillison.Net)
Summary: Simon Willison has released an alpha Python package, micropython-wasm, which uses a WebAssembly-compiled MicroPython interpreter to execute Python code within a sandboxed environment from a host Python application. The system aims to provide a secure, embeddable plugin runtime with controlled resource access, addressing a long-standing need in his open-source projects like Datasette. The implementation leverages wasmtime for WebAssembly execution and includes mechanisms for persistent interpreter state and controlled exposure of host functions.

Why it matters: For independent operators building extensible software, a robust, easy-to-deploy sandbox for plugins or user code mitigates a major security and stability risk, enabling more ambitious features without compromising core application integrity.
Context: Sandboxing dynamic language code in server-side applications remains a notoriously difficult problem, with many past solutions being abandoned or deemed unsafe. WebAssembly offers a promising, battle-tested foundation, but practical, maintainable embeddings for Python have been scarce.
"WebAssembly sure feels like a constrained environment to me!" — SIMONWILLISON.NET
Commentary: Willison’s prototype is valuable as field observation and a concrete argument worth testing: it demonstrates a pragmatic path to sandboxing by combining mature, low-level WebAssembly tooling with a lightweight interpreter. Its success hinges not on novelty but on whether it can attract the institutional support and rigorous security review he openly solicits, moving from a ‘vibe-coded’ proof-of-concept to a trusted component.

I Built My Own AI Harness (and Finally Understood the Tools I Use Every Day) (Javascript.Plainenglish.Io)
Summary: I Built My Own AI Harness (and Finally Understood the Tools I Use Every Day) Let me confess something embarrassing for someone who codes with AI all day. I run Claude Code and Codex every single day. They read my files, run my tests, edit ten things at once, and somehow Just Work.
