Ctrl+B backgrounding now applies the same background-shell caps as other paths Fixed agent frontmatter hooks running from untrusted folders: hooks now require the agent file's own folder to have accepted workspace trust Fixed fork-session lineage being lost after compaction in headless and SDK sessions Fixed a resumed session failing every turn, or crashing on resume, when its history held a malformed delta attachment Improved /ultrareview error feedback so Claude can correct an invalid argument instead of retrying it unchanged Improved auto mode: the dangerous-rm, background-&, and suspicious-Windows-path checks no longer open permission dialogs; the auto-mode classifier adjudicates them instead Improved sandbox command restrictions for IDE interactions Improved trust dialogs to name the repository root the grant covers Changed /deep-research to start only when invoked manually; Claude no longer launches it on its own Changed plan mode with auto to no longer prompt for Bash commands the static analyzer can't prove read-only; the auto-mode classifier judges them instead Added an announcement when fast mode changes as a result of switching models via /config model= or Remote Control Changed server-managed settings so benign feature and cost toggles no longer trigger the settings-approval prompt Changed agent markdown files to reject agent names containing :, which is reserved for plugin namespacing Changed skills with context: fork to run in the background by default; opt out per skill with background: false Added yes/no/on/off/1/0 (case-insensitive) as accepted values for skill and plugin frontmatter booleans, alongside true/false Fixed remote sessions continuing to send heartbeats after their worker was replaced, which left long-lived desktop and IDE processes retrying a rejected request every few seconds forever --- 引用前请核对原文;本文由星际流动整理:https://feed.astralor.com/items/itm_d690b977f1e85b575b9c9b09
