How to Share Your AI Context and Skills Across Devices

Key Takeaways

• Dropbox breaks absolute file paths on mobile and non‑Mac devices
• Git/GitHub offers version control but adds complexity for non‑technical users
• Skills default to ~/.claude/skills, requiring symlinks for cloud sync
• Obsidian Sync handles markdown notes with relative links across platforms
• Obsidian Sync enables seamless AI context sharing between Mac, iPhone, Windows admin

Pulse Analysis

As organizations embed large‑language models like Anthropic’s Claude into daily operations, the value of a well‑curated context repository and reusable skill set becomes a competitive advantage. Claude Code lets users augment the model with custom prompts, slash commands, and plug‑ins, but those assets live as plain files on the local machine. When a team member switches from a MacBook to an iPhone, or an admin on a Windows workstation needs the latest /today command, any break in file availability instantly degrades the model’s output. A robust syncing strategy therefore moves from a convenience to a necessity for reliable AI performance.

The author’s experiments with Dropbox, iCloud, GitHub, and Obsidian Sync reveal a common pain point: absolute file paths. Dropbox preserves the full macOS path (/Users/…) which works on identical machines but collapses on iOS or Windows, leading to broken links in Claude’s context graph. iCloud solves the path problem for Apple devices but excludes cross‑platform collaborators. GitHub offers version control and relative links inside a repository, yet demands command‑line proficiency and manual pull‑push cycles that non‑technical admins find daunting. Even creating a symlink from ~/.claude/skills to a cloud folder adds setup overhead without guaranteeing seamless updates.

Obsidian Sync strikes a balance by storing context as plain markdown files that Claude can read directly, while handling relative links automatically across macOS, iOS, and Windows clients. The service’s background synchronization eliminates manual commits, and its conflict resolution is sufficient for teams that edit different notes during limited overlapping hours. By placing the Claude skill directory inside an Obsidian vault and using a simple symlink, the author achieved instant, bidirectional updates for both personal devices and a remote admin in the Philippines. For enterprises, this low‑friction approach reduces onboarding time, safeguards AI consistency, and scales as more users adopt Claude‑driven workflows.
