Environment

• Platform: Claude Code
• Claude CLI version: 1.0.64
• Operating System: macOS Sequoia 15.5
• Terminal: Terminal App

Bug Description

After upgrading from Claude Code v1.0.63 to v1.0.64, the @-file autocomplete feature no longer triggers. Previously, typing @ in the editor would pop up a file-path suggestion list; this behavior has stopped working entirely.

---

Steps to Reproduce

1. Install or upgrade to Claude Code CLI version ≥ 1.0.64.
2. Open a project in the Claude Code editor on macOS Sequoia 15.5.
3. In any source file, type the @ character.
4. Observe that no file autocomplete suggestions appear.

---

Expected Behavior

Typing @ should trigger the file-path autocomplete dropdown, allowing selection of files within the project.

---

Actual Behavior

No autocomplete dropdown appears after typing @. Other completion features (e.g., symbol or keyword suggestions) continue to work as expected.

---

Additional Context

• Reverting to v1.0.63 restores @-file autocomplete functionality.

Please let me know if any additional logs or configuration details would help troubleshoot this regression.
