The check now applies to a set of names instead.\n\n- Images or other media in a tool's result that are not sent are now replaced with `[media removed: request limit]`. A tool result is what an action returns to Claude.\n\n- PDF reads inside messages are now counted as their own kind of content.\n\n- There is a new setting, off by default, beside a text block describing a document about the current project. It read off for this site's account when it was last checked.\n\n**Why**\n\nThese look like early work toward reading PDFs and attaching project documents. The visible part for now is the note that marks media that was not sent.\n\n- Flag `tengu_glittery_crayon`: Off in both readings (read for one account on one subscription tier against v2.1.318; this account: off, anonymous baseline: off, compiled default: off) These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.\n- Area: MCP\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
