Shared personal skills/instructions across all Claude agents

Feature request

Allow users to define a shared directory of personal skills/instructions that would be available across all Claude environments:

• Claude Code (CLI)
• claude.ai (web)
• Claude Agent SDK
• Third-party integrations

Motivation

Currently, each environment is siloed. Custom styles, instructions, and skills defined on claude.ai are not available in Claude Code, and vice versa. Users who work across multiple interfaces have to duplicate their configuration manually.

Proposed solution

A unified personal skill/instruction repository (perhaps synced via Anthropic account) that all Claude-powered agents can access, regardless of the interface. This could be:

• A cloud-synced ~/.claude/shared/ directory
• An API-accessible personal instruction store tied to the user's Anthropic account
• A convention for a git repo that all agents can reference

Context

Claude Code already has a hierarchical memory system (CLAUDE.md, ~/.claude/CLAUDE.md, project-level rules). Extending this to a cross-platform shared layer would be a natural evolution.
