Export confirmed skills for use by other agents

[Evenss]

Description

Background

Human-confirmed skills should be reusable by other agents or tools. Different agents often have fixed or conventional skill locations, such as a user-level skill directory, a project-level skill directory, or a tool-specific default skill directory.

The current Skills page can only download a combined skills.md file. It cannot export one or more confirmed skills into a local skill directory, nor can users choose a target agent or target path.

UI Scope

Skills page.

Proposal

• Allow users to export confirmed skills for use by other agents.
• Provide common export destination shortcuts, such as:
  • user-level default skill directory
  • current project skill directory
  • Codex / Cursor / other agent default skill directories
  • recently used export directories
• Allow users to manually choose a target folder.
• Remember the last used export directory.
• Support at least SKILL.md as an export format.
• The backend should write the skill to the target directory and handle name conflicts with a clear overwrite, skip, or rename strategy.
• Prevent exporting unconfirmed skills, or require confirmation before export.
• Show the target path after a successful export.
• Show clear error messages when export fails.

Acceptance Criteria

• A user can select a confirmed skill from the Skills page and export it.
• A user can choose from common export destinations.
• A user can manually choose an export directory.
• The exported directory contains the expected SKILL.md.
• Unconfirmed skills cannot be exported directly, or must be confirmed first.
• Name conflicts are handled through a clear overwrite, skip, or rename strategy.
• The UI shows the target path after successful export.
• Export failures show clear error messages.
