Turn off prompt suggestions in Grok Build

When prompt_suggestions is on, Grok Build shows next-prompt ghost text after each turn. Press Tab to accept the suggestion into the prompt. Official: Settings reference.

Config

User config (~/.grok/config.toml or $GROK_HOME/config.toml):

[ui]
prompt_suggestions = false

Default is true. Project .grok/config.toml does not own [ui] — only user config does.

Environment override

Process-scoped:

GROK_PROMPT_SUGGESTIONS=0 grok

Use 1 to force ghost text on for that process. Env wins for that launch when you need a one-off without editing the file.

When to leave it on

Keep prompt_suggestions = true if you want a ready follow-up after long tool turns and you habitually Tab-accept. Turn it off when ghost text fights your own draft or screen readers.

Pitfalls

• Editing project .grok/config.toml for [ui] — that file only contributes MCP, plugins, and permission rules.
• Expecting /settings alone to persist without a matching [ui] write — use config or env for a durable off switch.
