Simon Willison released llm-coding-agent 0.1a0, an experimental coding agent built on his LLM library. The agent provides tools for reading, editing, searching files and executing commands, and ships with a Python API and CLI. It was developed using Claude Code (Fable 5) via TDD with a spec-first approach, and is available as a slop-alpha on PyPI.
Simon Willison used DSPy to evaluate and improve Datasette Agent's SQL system prompts. DSPy identified that the schema listing lacked column names and that advice to avoid calling describe_table caused column-name guessing and error retries.
datasette-export-database 0.3a2 fixes a dependency issue where pyproject.toml incorrectly pinned datasette==1.0a27, making the plugin incompatible with other Datasette versions. The fix changes the requirement to datasette>=1.0a27.

Datasette-apps is a new system that allows users to bundle and install full applications within Datasette, turning it into a platform for data-driven apps. It enables developers to create self-contained packages combining SQLite databases, metadata, plugins, templates, and assets.
Datasette Apps is a new plugin that lets users host custom HTML+JavaScript apps inside Datasette in a sandboxed iframe with a Content Security Policy. The apps can run read-only SQL queries and optionally write data via stored queries. The feature supports AI-assisted creation through copyable prompts for LLMs.
datasette-acl 0.6a0 expands from table-only permissions toward a general resource-sharing system. The plugin, primarily developed by Alex Garcia, enables multi-user Datasette instances to have finely grained control over access to resources within Datasette.

It also includes keyboard navigation for the stored query picker, prevents #fragment links from triggering the confirmation modal, and fixes the link confirmation modal and logging panels in full-screen mode.
Simon Willison released an alpha package, micropython-wasm, that runs MicroPython code inside a WebAssembly sandbox via wasmtime. It enforces memory/CPU limits, restricts file and network access, and supports persistent state and host functions for safely executing untrusted code in Python applications.
