What
The Read tool is how Claude opens files. A file can be too large to read in one go. Claude Code then replies with a hint, and that hint is now built from several parts instead of one fixed message telling Claude to use the offset and limit options (which read a range of lines). For JSON files, the hint now explains that a long value, or the whole file, can sit on a single line, so offset and limit cannot split it. It suggests looking into the file with jq, a command-line tool for querying JSON.
Why
Claude is steered away from retrying line ranges that cannot work and toward a way that does, when it meets a big one-line JSON file.
