[FEATURE] Account-Level Skill Synchronization Between CLI and Web

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

Skills are currently environment-specific and require manual distribution. Personal skills in ~/.claude/skills/ only exist on the local machine and don't sync to Claude Code web or other machines.

Proposed Solution

Enable account-level skill synchronization for personal skills across all Claude Code environments (CLI, web, multiple machines).

• Sync ~/.claude/skills/ to cloud storage tied to user account
• Auto-sync when skills are created, modified, or deleted
• Available in both CLI and web environments when authenticated
• Optional: Allow users to opt-out of sync for specific skills

Benefits

1. Seamless workflow continuity across environments
2. Reduced friction for multi-device users
3. Clear separation: personal skills (cloud-synced) vs. project skills (git-based)

Alternative Solutions

Current Workarounds

1. Project skills - Use .claude/skills/ in git repos (but this mixes personal/project concerns)
2. Manual copying - Copy ~/.claude/skills/ across machines manually
3. Plugins - Convert skills to plugins (overhead for simple personal skills AND doesn't seem to work with web Claude Code)

Priority

Critical - Blocking my work

CLI commands and flags

Use Case Example

Users who work across multiple environments need their personal skills, preferences, and custom workflows to follow them automatically without:

• Manual setup on each machine
• Committing personal skills to project repos
• Maintaining separate skill collections per environment
