Grok Build Src e5fd4816d432

be713136d2a6→e5fd4816d432·August 12, 2026 at 11:12 PM UTC

Open-source sync to 1.0.3: faster subagent spawn and high-refresh TUI, richer /session-info, plus the 1.0.2 reliability and harness fixes.

Changelog

  • [changed] Subagent spawning is dramatically faster when you have many sessions in ~/.grok.
  • [changed] TUI rendering automatically matches high-refresh displays (120 Hz+) for smoother scrolling and painting.
  • [new] /session-info lets you click any row to copy its value, with hover highlights and a copy-all shortcut.
  • [changed] Tool-call argument streaming shows a distinct spinner label instead of a generic “Waiting for response…” message.
  • [changed] Harness includes UI-verification instructions and raises project/user rules higher in the prompt prefix.
  • [fix] Large sessions with images no longer exceed limits during compaction.
  • [fix] Recovery from server-rejected images no longer leaves sessions permanently unusable.
  • [fix] Startup timeout messages name the slowest step, show elapsed times, and give actionable advice.
  • [fix] Worktree copies of large repos no longer inherit dangerous fetch specs or stale shallow grafts.
  • [fix] Privacy banner can be dismissed from Settings even when you are already opted out.
  • [fix] Status bar keeps showing your current model after a catalog refresh even if that model is no longer listed.
  • [fix] Grouped tool calls stay grouped when hooks attach metadata, and show hook results in the header.
  • [fix] Cmd+click on autolinks in Apple Terminal opens the correct URL when multiple messages are visible.

Agent & tools

  • Agent communication guidance was rewritten for clearer, self-contained user-facing replies (lead with the answer; define project terms on first use; avoid coining shorthand).
  • When browser tools are available, the harness can require end-to-end UI verification for web-facing changes (routes, layout, desktop and mobile), including regression checks before finishing the turn.
  • /session-info copy interactions as noted above.

Docs

  • Hooks: exit-code and stderr feedback behavior clarified (first stderr line as deny reason / scrollback detail; stderr as the diagnostics channel).
  • Agent mode: notes that grok agent serve is self-hosted — Grok’s hosted cloud sandboxes do not run it.
  • Permissions and safety: Claude-style mcp__… MCP rule spellings are accepted and rewritten; dangerous-command “Always allow” is exact-match only; interactive grants scope to the git repository root (per worktree outside that model).

Under the hood

  • Product version and package set move to 1.0.3 (grok-build).
  • Session search, active-session tracking, session events, compaction transcript handling, foreign-session import paths, fuzzy file search, pager diff, bundle helpers, workspace daemon, and diag server live as dedicated workspace crates.
  • New environment knobs: GROK_IMAGE_CAPABILITIES_DIR, GROK_RESUME_NUDGE_DISABLED.

Upgrade notes

  • Rebuild from the updated workspace so the new crates and 1.0.3 package versions link cleanly.
  • If you rely on custom prompt or hook behavior around stderr/deny reasons or MCP allowlists, skim the hooks and permissions guide sections above.
