datasette-agent-edit 0.1a0 ships reusable agentic text-editing tools

`datasette-agent-edit 0.1a0` is an alpha release of a new base plugin for Datasette Agent, providing reusable, storage-agnostic tools for agentic text editing. The plugin implements three tools drawn from the Claude text editor design: `view`, which displays sections of a file with line numbers on every line; `str_replace`, which finds an exact `old_str` and replaces it with a `new_str`, failing if the original string is not unique; and `insert`, which inserts specified text after a given line number.

The post explains that agentic editing of text is described as "a little tricky to get right," and that the Claude text editor's published design was the inspiration for these tool patterns.

The post explains that agentic editing of text is described as "a little tricky to get right," and that the Claude text editor's published design was the inspiration for these tool patterns. Rather than re-implementing these tools in each individual plugin that requires editing capabilities, this base plugin centralizes the core logic so it can be adapted by other plugins. Several future Datasette Agent plugins are planned that will build on it, covering use cases such as collaborative Markdown editing, updating large SQL queries, and editing SVG files.
