Grok Build 0.2.90

0.2.89→0.2.90·July 7, 2026 at 10:37 PM UTC

Patch release that adds local filesystem path support when adding plugin marketplace sources, adjusts several configuration defaults, and documents the new MCP output size limit.

Changelog

  • [new] grok plugin marketplace add now accepts a local directory path in addition to git URLs and GitHub shorthands (updated across shell completions and user-guide documentation).
  • [changed] auto_interject_on_task_wait now defaults to false (previously true).
  • [changed] [toolset.ask_user_question] timeout_secs now defaults to 1800 (30 minutes) instead of 360 (6 minutes).
  • [new] MCP tool results are now capped at 20 000 bytes by default (configurable via GROK_MAX_MCP_OUTPUT_BYTES, MAX_MCP_OUTPUT_BYTES, or [mcp] max_output_bytes); oversized payloads are truncated inline with the full content written under the session mcp/ directory.

Under the hood

  • Updated help text and flag descriptions for --reasoning-effort/--effort to reflect expanded level names and TUI/headless availability.
  • Refined wording in the image, image-edit, image-to-video, and reference-to-video tool descriptions so they now recommend short session-relative paths when telling users where generated files were saved.

Upgrade notes

  • Review any scripts or workflows that relied on the previous defaults for auto_interject_on_task_wait or the ask-user-question timeout.
