            ## Task

            Your task is to transform the MATCH with the following TRANSFORM.
            Return the transformed text.
            - do NOT add enclosing quotes.

            ## Context
            `
                ctx.def("MATCHED", match[0])
                ctx.def("TRANSFORM", transform)
            },
            { label: match[0], system: [], cache: "search-and-transform" }
        )
        ...

    ...
    const transformed = res.fences?.[0].content ?? res.text
    patches[match[0]] = transformed

    const newContent = content.replace(
        patternRx,
        (match) => patches[match] ?? match
    )
    await workspace.writeText(file.filename, newContent)
}
