Doc files nobody asked for, and READMEs that grow by 40 or more lines nobody asked for

Comments and text: one of the ways AI coding agents bloat software, from lessloc's pattern catalog. lessloc catches it as unrequested-doc.

What makes doc files and README growth nobody asked for a bad practice?

The standard that calls it a bad practice: YAGNI.

Docs that restate the name: lessloc catches it as narration.
History and messages to the requester: lessloc catches it as history.
Comment blocks and comment-heavy changes: lessloc catches it as comment-block and comment-density.
Log lines that narrate each step: lessloc catches it as narration (three or more in a file).
Docs that still name what a change removed: lessloc catches it as stale-doc.
Summary, report and notes files: lessloc catches it as junk-file and refuses it before it lands.
Docs deleted wholesale to shrink a change: lessloc catches it as doc-removed.
Always-loaded instructions that grow: lessloc catches it as long-instructions.
Commit messages that recap the diff file by file: The commit hook warns when a message lists the files the diff shows.
