v1.0.52

1.0.52 — 2026-10-11

Features

• Rex terminal support: Grok now reports its status (working, waiting for you, done, or failed) to Rex through OSC 7501, so Rex tabs show what each session is doing.
• Tool call density improvements: expanded tool call groups now stay expanded as new calls join them, and Ctrl+E expands or collapses thinking faster in long transcripts.
• Project hooks placed in a repository subfolder are now loaded when you launch inside that folder.
• HTTP hooks to localhost now work, and bad hook URLs are reported at load time.
• Command status-line scripts now see the current turn's prompt ID and start time while the turn is active.

Bug Fixes

• Grep searches that time out or fail now show an error instead of appearing as empty results.
• /model switches that fail no longer change the footer or saved default model.
• Export and copy commands no longer overwrite an existing file; they refuse with a clear message.
• Shell commands no longer keep running after you quit grok or it receives a signal.
• Approval cards for background subagents no longer disappear when the parent turn ends.
• grok worktree rm and gc no longer delete a worktree that an open session is using.
• grok inspect no longer warns about valid pins that only requirements.toml accepts.
• Pasted images that exceed the 50 MB send limit are now rejected with a clear message instead of silently dropped.
• grok -p --effort now prints a warning when the model ignores the flag and refuses invalid effort levels.
• Permission prompts now show which session needs approval.
• grok worktree rm now refuses to delete git repositories, .git folders, or any directory grok did not create.
• Grep and list_dir now report a clear error when the search root or directory cannot be read instead of silently returning no results.
• Cancelled terminal commands now show the actual command that was stopped.
• Wrapped URLs in prompts and quotes now link to the complete address instead of being cut at the wrap.
• @mentions and image placeholders now respect Read deny rules and are omitted from the prompt.
• Restarting after a model switch no longer reverts to the previous model.
• Long tool turns that include PostToolUse hook output now compact correctly instead of hitting the prompt length limit.
• Headless prompts that start with a byte-order mark no longer send the mark to the model or break JSON prompt files.
• When a permission rule blocks a tool call, any context returned by a PreToolUse hook still reaches the model.
• An invalid shell_environment_policy table in config.toml now causes grok to exit with a clear error instead of silently using the full environment.
• MCP tool replies containing invalid characters no longer cause the call to time out.
• Context overflow errors now trigger automatic compaction instead of failing the turn.
• Inline tags in agent replies no longer break line layout, and /workflow stop now picks the correct live run.
• Auto-compaction now stops after three context refills in a row instead of looping forever.
• Minimal mode now shows the permission prompt instead of a hidden plan or cancel panel when both are present.
• Project rules files that resolve outside the git root or workspace folder are now skipped.
• [permission] rules now load alongside compact deny/allow/ask lists in config.toml.
• Unrecognized permission keys or [permissions] sections now appear as skipped entries in grok inspect.
• Approval cards now close the block viewer so the card is visible.
• Shell redirects to wildcard or variable paths now correctly respect deny rules in Auto mode.
• The in-session resume picker now matches the ungrouped layout shown on the welcome screen when configured.
• HTTP MCP tools that return a JSON-RPC error are now executed only once.
• StopFailure hook matchers containing commas or spaces are now treated as regex patterns.

Performance

• Multiple Notification hook chains now start in parallel instead of waiting for the previous chain to finish.
