Grok Build 0.1.217-alpha.5

Grok 0.1.217-alpha.5 adds grok plugin commands for managing plugins and marketplaces from the terminal, introduces the execute-plan skill for running design document PR plans, and improves image handling, subagent credential usage, MCP connections, signal sync, Cursor agent image transcription, and authentication recovery after subscription changes.

Added

• grok plugin commands for listing, installing, uninstalling, updating, enabling, disabling, validating, and tagging plugins, plus marketplace management commands (grok plugin marketplace list|add|remove|update).
• New bundled skill execute-plan that parses a PR Plan DAG from a design document, runs parallel implementation and review subagents in isolated worktrees, and assembles a Graphite PR stack. Trigger with /execute-plan <design-doc-path> or when users say "execute plan", "run the plan", or "implement the design".
• Ctrl+Enter interjection support during an active agent turn (continues the current turn without cancellation), documented in keyboard shortcuts and terminal support guides.

Changed

• Plugin documentation expanded with full CLI command reference, source argument formats, and an example for setting up a team marketplace.
• Terminal support guide now includes WezTerm configuration steps and a one-line keybinding workaround to enable Ctrl+Enter interjection and modified Enter keys in multiline mode.

Fixed

• Image pasting now correctly prefers images from the clipboard and keeps dragged screenshots visible.
• Subagents now correctly use bring-your-own-key credentials when the parent model specifies them.
• MCP server connections no longer fail with initialization errors under concurrent tool calls.
• Signal sync is more resilient to transient authentication hiccups.
• Authentication recovery after subscription changes no longer causes duplicate IdP calls.
• Cursor agent now transcribes attached images more accurately with better truncation and processing limits.

Removed

• Shell completion scripts for bash and zsh.
• User guide pages covering project rules, memory, headless mode, agent mode, subagents, sessions, sandbox, plan mode, background tasks, and terminal support.
• Older vendored ripgrep binary for aarch64-linux.

Upgrade notes

None.
