sqlite-utils 4.0, now with database schema migrations

sqlite-utils 4.0 is released, the first major version bump since 3.0 in November 2020. It introduces three major features: database migrations, nested transactions (via a new db.atomic() method), and support for compound foreign keys. Additionally, there are breaking changes including upserts using INSERT ... ON CONFLICT, db.query() executing immediately and rejecting non-query statements, and CSV/TSV importing with automatic type detection by default. The article details the migration system, compares it to Django's migrations, covers migration from the separate sqlite-migrate package, and highlights the significant role AI models (Claude Fable 5, Opus 4.8, GPT-5.5) played in development and testing.

Anthropic is launching Claude Cowork on mobile and web

Starting Tuesday, Anthropic's Claude Cowork AI platform will be available on mobile and web for the first time. The expanded access is rolling out first to Max subscribers and coming to Claude users on other plans "in the coming weeks." Claude Cowork was previously only accessible through the Claude desktop app for macOS and Windows, but now users on iOS and Android can also use it. However, Anthropic says the "full experience" for Cowork will still be on the desktop app, including features like local file access. Cowork sessions will also now run in the cloud by default, so you can continue them across different devices or run Cowork tasks in the background even when your laptop is closed. There’s still an option for local processing on the desktop app, where users can switch between cloud and local processing. Additionally, scheduled tasks will now run even when none of your devices are online. Claude can also send Cowork notifications to your phone when it has something ready for you to review or approve. Alongside Cowork’s mobile and web launch, Anthropic is also extending its doubled Cowork usage limits through August 5th.

Why AI Agents Forget by Design

The article explains that major LLM APIs (OpenAI, Anthropic, Google) are stateless by default, meaning each API call is independent and the model has no inherent memory. This architectural choice forces developers to resend entire conversation histories per request, leading to high costs, latency, and performance degradation (lost-in-the-middle effect). The author identifies four production failure modes: re-explanation, knowledge loss on handoff, contradiction without resolution, and hallucination over abstention. Current mitigation patterns (prompt stuffing, fine-tuning, RAG, vector databases, etc.) are partial solutions. The temporal validity of stored facts remains an unsolved problem.

Beating a text-to-SQL benchmark: can you get better than plain Claude?

Motley achieved a 75.3% pass rate on the BIRD-INTERACT benchmark using the Claude SDK and SLayer, far surpassing the official best of 36.33%. The largest improvement came from the agent harness (Claude SDK), with SLayer adding a modest edge. Many gold answers in the benchmark were found to be incorrect; an annotation agent built by the team yielded higher corrected pass rates.
