Grok Build just got a pretty substantial upgrade across MCP, memory, long-running sessions, and overall agent reliability MCP tools can now return structured JSON, cancelled tool calls actually tell the server to stop working, memory can be managed directly from the /memory browser, and long-running sessions keep their compaction checkpoints instead of losing them during cleanup There are also fixes for macOS image pasting, subagent cancellation states, /rewind, huge skill files flooding context, Windows cloning, and minimal-mode session handling A lot of edge cases cleaned up here...especially for people running heavy agent workflows for long periods Release Notes: v1.0.33 Features: • MCP tool results now include structured JSON data when the server provides it. • GROK_GROVE=1 now enables both clone and worktree features when specific knobs are unset; missing remote settings no longer force copy. • Delete memories from the /memory modal using two-press x; only actual notes (not generated indexes) can be removed. • Composer footer now shows the Alt+Enter chord for inserting a newline when Cmd+Enter is unavailable over SSH. • /memory now always opens the memory browser modal; status and toggle are available via keys inside the modal instead of command arguments. Bug Fixes: • Fixed a bug where pasting an image on macOS could attach the wrong image. • MCP tool calls listed directly now show their name, arguments, and any error message. • Background subagent tasks now correctly show cancelled status when the parent session closes. • The Subagents dock no longer shows an unclickable "Done N completed" row after all subagents finish. • Cancelled or timed-out MCP tool calls now notify the server so it can stop work instead of continuing in the background. • /rewind no longer fails when older compaction checkpoints are missing after a session sweep; only the base checkpoint for the target matters. • Large skill files are now capped at the same 25k-token limit as other reads; oversized skill bodies show a truncation note instead of flooding context. • Long-running sessions no longer lose old compaction checkpoints or prompt offloads during the 30-day cleanup sweep. • Auto "where was I" recaps no longer appear while a scheduled task, monitor, or workflow is still running. • In minimal mode, confirming /delete or /exit now immediately opens a new empty session instead of appearing stuck. • In minimal mode, resuming a session after /new now correctly reloads its history instead of showing the wrong session. • MCP tools that take no arguments no longer show a stray "{}" line in the permission sheet. • Fixed Windows clone and attach failures when .git/config values contain backslashes, quotes, or other characters that must be escaped. • /memory modal now shows clear explanations when memory is disabled and helpful empty states instead of blank panes. • /memory (and on/off toggles) no longer leaves user bubbles or host turns in scrollback when opening or changing the modal. • Fixed Windows clone staging directories that could not be cleaned up after deadline or cancel during shallow bootstrap.
