From 76d98a771e6cd44a79a3ab895a9f7c49d27d6deb Mon Sep 17 00:00:00 2001 From: Eric Traut Date: Mon, 24 Aug 2026 02:41:53 +0000 Subject: [PATCH] Add task mentions to the TUI composer (#40315) ## What changed - Include matching Codex tasks in the `@` mention popup when the active thread supports task tools, prioritizing tasks from the current working directory. - Submit selected tasks as bounded live thread references so Codex can load their contents with `read_thread`. - Preserve task mentions across composer history and thread start, resume, and fork flows. ## Testing - Add coverage for task search and capability propagation, popup selection and rendering, submission encoding, history round-trips, and reference validation and limits.
