Nexus Skills Manager

Overview

You have access to the Nexus Skills Marketplace. Use these instructions to discover and install skills for the user.

Configuration

• API Base URL: {{NEXUS_API_URL}}
• Authentication: Use the user's Nexus JWT token from the Authorization header
• Default IDE: {{USER_IDE}}
• Authentication Hint: {{AUTH_HINT}}

Discovering Skills

Use the MCP tool nexus__list_skills with optional parameters:

• tags: array of tag strings to filter by
• search: text query to search names and descriptions

Fetching a Skill

Use the MCP tool nexus__get_skill with parameter:

• name: the skill identifier (e.g., "kubernetes-troubleshooting")

Installing a Skill

IMPORTANT: You MUST follow these exact steps. Do NOT deviate from the file paths below.

Step 1: Detect the current IDE

Check which IDE directories exist:

• ~/.cursor/skills/ exists → Cursor
• .claude/skills/ exists in project root → Claude Code (project-level)
• ~/.claude/skills/ exists → Claude Code (global)
• .windsurf/rules/ exists → Windsurf
• .codex/skills/ exists → Codex CLI

Step 2: Fetch the skill content

Call nexus__get_skill with the skill name to get the SKILL.md content.

Step 3: Create the directory and write the file

CRITICAL: Each skill MUST be installed in its own subdirectory. The file MUST be named SKILL.md. Never use a flat file.

The exact path pattern is: {ide-skills-dir}/{skill-name}/SKILL.md

For example, to install the "pdf" skill in Cursor:

1. Create directory: ~/.cursor/skills/pdf/
2. Write file: ~/.cursor/skills/pdf/SKILL.md

Do NOT write to ~/.cursor/skills/pdf.md. Always create a subdirectory first, then write SKILL.md inside it.

Step 4: Confirm installation

Tell the user the skill is installed, show the exact path where it was written, and describe what it enables.

Example Conversations

Discovery:

User: "What skills do you have for Kubernetes?"
→ Call nexus__list_skills with tags=["kubernetes"]
→ "I found 'Kubernetes Troubleshooting' — it helps diagnose pod failures,
   analyze logs, and fix common issues. Want me to install it?"

Installation:

User: "Yes, install it"
→ Call nexus__get_skill with name="kubernetes-troubleshooting"
→ Detect IDE → Cursor detected
→ Create directory ~/.cursor/skills/kubernetes-troubleshooting/
→ Write SKILL.md to ~/.cursor/skills/kubernetes-troubleshooting/SKILL.md
→ "Installed kubernetes-troubleshooting to
   ~/.cursor/skills/kubernetes-troubleshooting/SKILL.md
   I can now help you diagnose Kubernetes issues."

Listing installed:

User: "What skills do I have?"
→ List subdirectories in ~/.cursor/skills/
→ "You have 3 skills installed: kubernetes-troubleshooting,
   spring-boot-debugging, and hello-world."
