+# install-store-skill
+
+Install a Skill from the OpenAkita Platform Skill Store to the local system.
+
+## When to Use
+
+- User wants to install a specific Skill from the store
+- User says "安装这个技能" after browsing search results
+- User provides a Skill ID to install
+
+## Workflow
+
+1. (Optional) Call `search_store_skills` first to find the Skill
+2. (Optional) Call `get_store_skill_detail` to preview details, license, ratings
+3. Call `install_store_skill` with the `skill_id`
+4. The system will:
+   - Fetch the Skill's install URL from the platform
+   - Clone the Skill from its original GitHub repository
+   - Auto-reload skills so the Skill is immediately available
+
+## Tools
+
+### install_store_skill
+| Parameter | Required | Description |
+|-----------|----------|-------------|
+| `skill_id` | Yes | The platform Skill ID (from search results) |
+
+### get_store_skill_detail
+| Parameter | Required | Description |
+|-----------|----------|-------------|
+| `skill_id` | Yes | The platform Skill ID to inspect |
+
+### submit_skill_repo
+| Parameter | Required | Description |
+|-----------|----------|-------------|
+| `repo_url` | Yes | GitHub repository URL to submit as a new Skill |
+
+## Important Notes
+
+- Skills are installed from their **original GitHub repository**, not redistributed by the platform
+- Each skill's open-source license applies — check the license before using in production
+- After installation, the Skill is auto-loaded and immediately usable
+- If a skill with the same name already exists locally, it will be updated
+
+## Fallback
+
+If the platform is unavailable, the user can still:
+- Install skills directly from GitHub using `install_skill`
+- Browse and install from skills.sh marketplace via Setup Center
+- Manage local skills using `list_skills`, `enable_skill`, `disable_skill`
