What issue are you seeing?

Summary

In the Codex VS Code extension, I can use / to select one skill, but after inserting the first skill, typing / again in the same message does not open the skill picker anymore.

This is inconsistent with the Codex app, where I can select multiple skills in the same message using /.

Environment

• Product: Codex VS Code extension
• Extension version: openai.chatgpt-26.313.41514
• IDE: VS Code / Cursor
• Date observed: March 19, 2026
• Workspace type: local project
• Account: same account used in both Codex app and VS Code extension

What steps can reproduce the bug?

Steps to reproduce

1. Open the Codex panel in the VS Code extension.
2. Start a new message in the composer.
3. Type / and select a skill.
4. Continue typing in the same message.
5. Type / again to select a second skill.

What is the expected behavior?

Expected behavior

• The slash skill picker should open again, so I can insert a second skill in the same message.
• Behavior should match the Codex app.

Actual behavior

• After the first skill is inserted, typing / again does not show the skill picker.
• As a result, I cannot select a second skill via slash in the same message.

Additional information

Notes

• This appears to be specific to the VS Code extension UI/composer behavior.
• The same workflow works in the Codex app with the same account and skill set.
• Skills themselves are available; the issue seems to be with repeated slash-triggered selection in the extension composer.

Impact

• Multi-skill prompting is harder in the VS Code extension.
• This creates inconsistent behavior between Codex app and Codex IDE extension.
