• Added slash-command and skill expansion to print mode, so a headless run such as -p "/my-skill review this diff" now resolves and applies the skill instead of sending it as literal text, with --disable-slash-commands to opt out.
• Improved interactive startup so a slow or hanging MCP server no longer stalls the first agent turn, loading MCP servers in the background for the interactive session while headless and one-shot runs keep blocking so their single scripted turn still sees the full toolset.
• Improved permission grants so a pattern approved at a prompt is recorded for the rest of the conversation, letting later commands that match it run without prompting again.
• Improved the default system temporary-directory grant to cover writes as well as reads, so agents no longer trigger a permission prompt when creating or updating files there.
• Fixed stop hooks that always block hanging the agent forever; after a configurable number of consecutive continuations, the hook can no longer block and the turn ends normally.
• Fixed PostToolUse hooks firing on non-tool steps such as user input and model responses, which also caused them to ignore their configured matchers.
• Fixed slash commands not being recognized when separated from their arguments by a newline or tab, so a prompt starting with a command followed by a newline is now parsed as a command instead of being sent verbatim.
• Fixed deleting into a collapsed paste placeholder removing one character at a time, which left a visible fragment in the prompt while the full pasted content was still submitted; the block is now deleted atomically.
• Fixed the artifact viewer losing syntax highlighting when returning from the editor view, and returning to the wrong panel when exiting the artifact detail view.
• Fixed the headless stream-json init event advertising tools that are not available in your build.
• Fixed MCP servers forcing a full re-authentication after a dropped connection.
