It is aware of a complete lot of methods and it&#8217;ll deploy just about any of them to get to its objective.<\/p>\n<p>I\u2019ll illustrate this with an instance. I used to be hacking on Datasette Agent right this moment once I seen a glitch: a horizontal scrollbar that shouldn\u2019t be there within the leap menu chat immediate. I snapped this screenshot:<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/static.simonwillison.net\/static\/2026\/jump-to-bug.jpg\" alt=\"Screenshot of a modal dialog demonstrating a scrollbar bug. At the top is a focused search input with blue outline and placeholder &quot;Jump to...&quot;, with an X close button to its right. Below, a heading reads &quot;Start a new agent chat&quot; above a textarea with the placeholder &quot;Ask a question about your data...&quot; \u2014 the bug: a thick gray horizontal scrollbar is incorrectly displayed along the bottom edge of the empty textarea, spanning nearly its full width, next to the resize handle. Below the textarea: &quot;Press Enter to start. Shift+Enter adds a new line.&quot; followed by a blue &quot;Start chat&quot; button.\" style=\"max-width: 100%;\"\/><\/p>\n<p>Then I began a contemporary claude session in my datasette-agent checkout, dragged within the screenshot and informed it:<\/p>\n<blockquote>\n<p>Take a look at dependencies to assist work out why there&#8217;s a horizontal scrollbar right here<\/p>\n<\/blockquote>\n<p>I had a hunch the trigger was in a dependency of Datasette Agent (probably Datasette itself) and I knew Fable was good at digging into dependency code, both by inspecting put in recordsdata in its personal digital surroundings site-packages or by referencing an area checkout on disk. Telling it to begin with dependencies felt like a great wager.<\/p>\n<p>I acquired distracted by a home job and wandered away from my laptop.<\/p>\n<p>After I got here again a couple of minutes later I noticed my machine open a browser window in my common Firefox after which navigate to the dialog in query. I had not informed Claude Code to make use of any browser automation, and I used to be fairly positive it wasn\u2019t potential for it to set off mouse actions or keyboard shortcuts inside a window, so how was it doing that?<\/p>\n<p>I watched in fascination because it continued with its explorations, then noticed it open a Safari window as an alternative of Firefox. I additionally grabbed this snapshot from the Claude terminal:<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/static.simonwillison.net\/static\/2026\/fable-bash-pyobjc.jpg\" alt=\"Screenshot of two Bash tool calls in a dark terminal interface.

Second: Bash(screencapture -x -o -l 153551 \/tmp\/safari-cases.png &amp;&amp; echo ok) with output ok.\" style=\"max-width: 100%;\"\/><\/p>\n<p>What was it doing there with uv run &#8211;with pyobjc-framework-Quartz?<\/p>\n<p>It seems Fable had hacked up its personal sample for taking screenshots of browser home windows. It was utilizing Python to iterate by means of all obtainable home windows on my machine, then filtering for Safari home windows with anticipated strings resembling &#8220;textarea&#8221; within the window identify. It used that to seek out their window quantity\u2014an integer like 153551\u2014which it may then use with the screencapture CLI instrument to seize a PNG.<\/p>\n<p>OK wonderful, that\u2019s a neat method of taking screenshots. However what was it taking screenshots of?<\/p>\n<p>Seems it had been writing its personal scratch HTML pages to attempt to recreate the bug, then opening Safari and grabbing screenshots.<\/p>\n<p>Right here\u2019s that \/tmp\/textarea-scrollbar-test.html web page it created, and the screenshot it took with screencapture -x -o -l 153551 \/tmp\/safari-cases.png:<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/static.simonwillison.net\/static\/2026\/safari-cases.jpg\" alt=\"Screenshot of a Safari browser window showing a textarea scrollbar test page at file:\/\/\/private\/tmp\/textarea-scrollbar-test.html.

That\u2019s solely obtainable through a click on or a keyboard shortcut, and I couldn\u2019t see a mechanism for it to run these in Safari.<\/p>\n<p>I finally discovered what it had completed.<\/p>\n<p>Claude was working in a folder that contained the supply code for the applying. It is aware of sufficient about Datasette to have the ability to run an area improvement server. It seems it was enhancing Datasette\u2019s personal templates so as to add JavaScript that might set off the right keyboard shortcut as quickly because the window opened, including code like this:<\/p>\n<div class=\"highlight highlight-text-html-basic\"><span class=\"pl-kos\">&lt;<\/span><span class=\"pl-ent\">script<\/span><span class=\"pl-kos\">&gt;<\/span><br \/>\n<span class=\"pl-smi\">window<\/span><span class=\"pl-kos\">.<\/span><span class=\"pl-en\">addEventListener<\/span><span class=\"pl-kos\">(<\/span><span class=\"pl-s\">&#8220;load&#8221;<\/span><span class=\"pl-kos\">,<\/span> <span class=\"pl-k\">operate<\/span> <span class=\"pl-kos\">(<\/span><span class=\"pl-kos\">)<\/span> <span class=\"pl-kos\">{<\/span><br \/>\n  <span class=\"pl-en\">setTimeout<\/span><span class=\"pl-kos\">(<\/span><span class=\"pl-k\">operate<\/span> <span class=\"pl-kos\">(<\/span><span class=\"pl-kos\">)<\/span> <span class=\"pl-kos\">{<\/span><br \/>\n    <span class=\"pl-smi\">doc<\/span><span class=\"pl-kos\">.<\/span><span class=\"pl-en\">dispatchEvent<\/span><span class=\"pl-kos\">(<\/span><span class=\"pl-k\">new<\/span> <span class=\"pl-v\">KeyboardEvent<\/span><span class=\"pl-kos\">(<\/span><span class=\"pl-s\">&#8220;keydown&#8221;<\/span><span class=\"pl-kos\">,<\/span> <span class=\"pl-kos\">{<\/span><span class=\"pl-c1\">key<\/span>: <span class=\"pl-s\">&#8220;https:\/\/simonwillison.web\/&#8221;<\/span><span class=\"pl-kos\">,<\/span> <span class=\"pl-c1\">bubbles<\/span>: <span class=\"pl-c1\">true<\/span><span class=\"pl-kos\">}<\/span><span class=\"pl-kos\">)<\/span><span class=\"pl-kos\">)<\/span><span class=\"pl-kos\">;<\/span><br \/>\n  <span class=\"pl-kos\">}<\/span><span class=\"pl-kos\">,<\/span> <span class=\"pl-c1\">1200<\/span><span class=\"pl-kos\">)<\/span><span class=\"pl-kos\">;<\/span><br \/>\n<span class=\"pl-kos\">}<\/span><span class=\"pl-kos\">)<\/span><span class=\"pl-kos\">;<\/span><br \/>\n<span class=\"pl-kos\"\/><span class=\"pl-ent\">script<\/span><span class=\"pl-kos\">&gt;<\/span><\/div>\n<p>1.2 seconds after the window opens, this code triggers a simulated \/ key, which is the keyboard shortcut for opening the modal dialog.<\/p>\n<p>There was one problem left.
