Anonymous. No account, no email.
When piping content into Claude Code, if the input exceeds the internal limit (1 MB), the excess is now silently truncated and a warning is printed to stderr: warning: piped stdin exceeds <limit> bytes, truncated. Previously, very large piped inputs could cause issues.
Evidence
New stdin truncation handler (search for "piped stdin exceeds")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
