Claude Code now explains size and media limits more directly.
Details
- Piped stdin that exceeds the size cap tells users to pass large content as a file path.
- Oversized remote requests tell users to shorten the prompt or send it in parts.
- Media rejected by the API is replaced with an explicit placeholder instead of failing opaquely.
- PDF content returned by inner
Readcalls can be surfaced as document content blocks.
Evidence
User-facing limit messages (search for "piped stdin input exceeds", "request exceeds", "(media removed — rejected by API)", and "PDFs returned by inner Read calls")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
