From aab2eceb3dc3dd47d5993e21b0a44d7dd392b22b Mon Sep 17 00:00:00 2001 From: Saty <5752427+SatyPardus@users.noreply.github.com> Date: Sun, 18 Oct 2026 20:42:47 +0200 Subject: [PATCH] Checks without waiting: td_check wait:false and td_check_result A tool call blocks most AI apps, so an agent waiting for the server's compile could do nothing else. td_check with wait: false queues the check and returns its id at once; td_check_result fetches the state and the result later (POST /api/check { wait: false }, GET /api/checks/:id). The guidance tells agents never to wait idle: start the check, keep working or review, fetch the result afterwards.
