PSA - Claude Code: Turn off Prompt Suggestions, save ~10% of your limits/spend

Prompt Suggestions in Claude Code, the greyed-out text, perform a Cache Read of the entire context to generate suggestions like "commit and push." This process is expensive, potentially consuming up to 10% of weekly Fable limits. Users can save on usage and spend by disabling these suggestions. One user noted that suggestions cost them 91% of their normal prompt cost, highlighting the significant impact on resource consumption, though disabling them won't double overall usage.
