 ### 6. use single-file grep reads efficiently
 
 v2.1.160 removed the read-after-grep requirement for single-file `grep`/`egrep`/`fgrep` commands. if claude greps a single file to understand it before editing, that single grep now satisfies the read-before-edit check. this saves a separate Read call and keeps context tighter.
