Claude Code already cut long descriptions down to a maximum length. When it sets up MCP tools, it now also makes a second copy of each description, shortened to a different length limit. The length limit can also now be passed in rather than always worked out the same way.\n\n**Why**\n\nThe same MCP tool description may now be shortened to different lengths in different places.\n\n- Area: MCP\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
