What's Wrong?

Contextual prompt suggestions (grayed-out follow-up suggestions
appearing in the input
box after each Claude response, based on the current conversation
context) stopped
working approximately March 1-2, 2026.

This feature was working reliably for a long time before that. It is
distinct from the
basic "new session" prompt suggestion — it generated contextual
follow-ups throughout
the entire conversation.

## Environment

• Claude Code version: 2.1.68
• OS: Ubuntu 24.04 (Linux)
• Connection: SSH session
• Subscription: Claude Max

What Should Happen?

After each Claude response, grayed-out suggestions should appear in
the input box
based on the current conversation context (not just git history
suggestions at session
start).

Error Messages/Logs

Steps to Reproduce

1. Open terminal and start Claude Code: claude
2. Type any message and send it (e.g. "help me refactor this

function")

1. Wait for Claude to finish responding
2. Observe the input box — no grayed-out contextual suggestion appears
3. Repeat for several back-and-forth turns — suggestions never appear

## What used to happen (before ~March 1-2)

After each Claude response, a grayed-out suggestion would appear in
the input box
reflecting the current conversation topic (e.g. if discussing
refactoring, it might
suggest "add tests for this function" or "explain what this does").
Pressing Tab would accept the suggestion.
This worked consistently throughout entire conversations, not just at
session start.
