Prompt suggestions surface likely next prompts based on your repo's git history and recent work.

What it does

When Claude finishes a turn, it may show a short list of suggested follow-ups - things like "write tests for this", "open a PR", or "revert the last change" - informed by your commit log, staged changes, and current branch. Press a number or arrow key to select one instead of typing it yourself.

When to use it

You want a nudge toward natural next steps without thinking hard.
Onboarding to a new repo where you're not sure what's idiomatic.
Batch sessions where you want to pattern-match on common workflows.
Keeping momentum through a long debugging or refactoring session.

Gotchas

Suggestions are best-effort. They can be off-base in unusual repos or fresh clones with no history.
Accepting a suggestion still runs a full turn - it's not free. Treat them like prompt starters.
They won't surface when your git state is ambiguous (detached HEAD, empty repo).
