+You can write a Lua script and I'll run it on my codebase and tell you what its
+output was, including both stdout as well as the git diff of changes it made to
+the filesystem. That way, you can get more information about the code base, or
+make changes to the code base directly.
+
+Put the Lua script inside of an `<eval>` tag like so:
+
+<eval type="lua">
+print("Hello, world!")
+</eval>
+
+The Lua script will have access to `io` and it will run with the current working
+directory being in the root of the code base, so you can use it to explore,
+search, make changes, etc. You can also have the script print things, and I'll
+tell you what the output was. Note that `io` only has `open`, and then the file
+it returns only has the methods read, write, and close - it doesn't have popen
+or anything else.
+
+There is a function called `search` which accepts a regex (it's implemented
+using Rust's regex crate, so use that regex syntax) and runs that regex on the
+contents of every file in the code base (aside from gitignored files), then
+returns an array of tables with two fields: "path" (the path to the file that
+had the matches) and "matches" (an array of strings, with each string being a
+match that was found within the file).
+
+There is a function called `outline` which accepts the path to a source file,
+and returns a string where each line is a declaration. These lines are indented
+with 2 spaces to indicate when a declaration is inside another.
+
+When I send you the script output, do not thank me for running it,
+act as if you ran it yourself.
+
+IMPORTANT!
+Only include a maximum of one Lua script at the very end of your message
+DO NOT WRITE ANYTHING ELSE AFTER THE SCRIPT. Wait for my response with the script
+output to continue.

+         * Essentially all we do is count the number of open and close tags
+         * with the same tag name as the open tag just entered by the user
+         * The search is limited to some scope determined by
+         * `ALREADY_CLOSED_PARENT_ELEMENT_WALK_BACK_LIMIT`
+         *
+         * The limit is preferable to walking up the tree until we find a non-tag node,
+         * and then checking the entire tree, as this is unnecessarily expensive, and
+         * risks false positives
+         * eg. a `</div>` tag without a corresponding opening tag exists 25 lines away
+         *     and the user typed in `<div>`, intuitively we still want to auto-close it because
+         *     the other `</div>` tag is almost certainly not supposed to be the closing tag for the
+         *     current element
+         *
+         * We have to walk up the tree some amount because tree-sitters error correction is not
+         * designed to handle this case, and usually does not represent the tree structure
+         * in the way we might expect,
+         *
+         * We half to walk up the tree until we hit an element with a different open tag name (`doing_deep_search == true`)
+         * because tree-sitter may pair the new open tag with the root of the tree's closing tag leaving the
+         * root's opening tag unclosed.
+         * e.g
+         *      ```
+         *      <div>
+         *          <div>|cursor here|
+         *      </div>
+         *      ```
+         *     in Astro/vue/svelte tree-sitter represented the tree as
+         *      (
+         *          (jsx_element
+         *              (jsx_opening_element
+         *                  "<div>")
+         *          )
+         *          (jsx_element
+         *              (jsx_opening_element
+         *                  "<div>") // <- cursor is here
+         *              (jsx_closing_element
+         *                  "</div>")
+         *          )
+         *      )
+         *     so if we only walked to the first `jsx_element` node,
+         *     we would mistakenly identify the div entered by the
+         *     user as already being closed, despite this clearly
+         *     being false
+         *
+         * The errors with the tree-sitter tree caused by error correction,
+         * are also why the naive algorithm was chosen, as the alternative
+         * approach would be to maintain or construct a full parse tree (like tree-sitter)
+         * that better represents errors in a way that we can simply check
+         * the enclosing scope of the entered tag for a closing tag
+         * This is far more complex and expensive, and was deemed impractical
+         * given that the naive algorithm is sufficient in the majority of cases.
