skillport 0.6.0

Bring Agent Skills to Cursor / Copilot / Codex & more — via CLI or MCP. Manage once, serve anywhere.

⚓ SkillPort

🚢 All Your Agent Skills in One Place - Manage once, serve anywhere ⚓

Agent Skills → Cursor · Copilot · Codex & more - via CLI or MCP

Why SkillPort?

Claude Agent Skills are great - but they only work in Claude. What about Cursor, Copilot, Codex? With dozens of skills loaded upfront, there's less context and agent performance suffers.

Context Engineering for Expert Knowledge - SkillPort brings expertise into context-only when needed.

Don't want to set up MCP	CLI works standalone - init, add, doc to AGENTS.md	CLI Mode →

🔄 Compatible with Claude Agent Skills - Write skills once, use everywhere. Skills that work with Claude Code work with SkillPort, and vice versa.

Quick Start (5 min)

Choose your setup:

Mode	Best for	Per-project setup
MCP Mode	Multi-project, per-client filtering	Not required
CLI Mode	Quick Setup, single project	Required (skillport init)

Tip: Start with MCP Mode for the full experience. CLI Mode is simpler but requires setup in each project.

MCP Mode

1. Install

Skip this step if you only want to serve an existing skills directory via MCP.

Install to manage skills and use them without MCP:

uv tool install skillport
# or: pip install skillport

# Update to latest version
uv tool upgrade skillport

Enables add, update, remove, validate, search, show, and doc (generate AGENTS.md for non-MCP agents).

2. Add Skills

Skip this step if you already have skills (e.g., in .claude/skills/). Just point SKILLPORT_SKILLS_DIR to it in step 3.

# Add a sample skill
skillport add hello-world

# Or add from GitHub (shorthand format)
skillport add anthropics/skills skills              # specific path
skillport add anthropics/skills skills examples     # multiple paths (1 download)

# Or add from GitHub (full URL)
skillport add https://github.com/anthropics/skills/tree/main/skills

# With custom skills directory (Claude Code, Codex)
skillport --skills-dir .claude/skills add anthropics/skills skills
skillport --skills-dir ~/.codex/skills add anthropics/skills skills/frontend-design

3. Add to Your MCP Client

To customize environment variables, use manual configuration below instead of one-click install.

Cursor (one-click)

VS Code / GitHub Copilot (one-click)

Kiro (one-click)

CLI Agents

# Codex
codex mcp add skillport -- uvx skillport

# With custom skills in the project directory
codex mcp add skillport --env SKILLPORT_SKILLS_DIR=./.agent/skills -- uvx skillport

# Claude Code
claude mcp add skillport -- uvx skillport

# With custom skills directory
claude mcp add skillport --env SKILLPORT_SKILLS_DIR=~/.claude/skills -- uvx skillport

Other MCP Clients (Windsurf, Cline, Roo Code, Antigravity, etc.)

Add to your client's MCP config file:

{
  "mcpServers": {
    "skillport": {
      "command": "uvx",
      "args": ["skillport"],
      "env": { "SKILLPORT_SKILLS_DIR": "~/.skillport/skills" }
    }
  }
}

Client	Config file
Windsurf	~/.codeium/windsurf/mcp_config.json
Cline	VS Code settings or .cline/mcp_settings.json
Roo Code	.roo/mcp.json (project) or VS Code settings

Claude Desktop (Not Recommended, Use the official Agent Skills)

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "skillport": {
      "command": "uvx",
      "args": ["skillport"],
      "env": { "SKILLPORT_SKILLS_DIR": "~/.skillport/skills" }
    }
  }
}

4. Use It

Ask your AI: "Search for hello-world and run it"

The agent will:

1. search_skills("hello-world") - find matching skills
2. load_skill("hello-world") - get instructions + path
3. Follow the instructions using its tools

---

CLI Mode

For: Coding agents with shell commands (Cursor, Windsurf, Cline, Copilot, Codex, etc.)

Skills are documented in AGENTS.md and load via skillport show. No MCP configuration needed.

# 1. Install
uv tool install skillport

# 2. Initialize your project (in your project directory)
skillport init
# → Select skills directory and instruction files interactively
# → Creates .skillportrc, generates skills to AGENTS.md

# 3. Add skills (uses skills_dir from .skillportrc)
skillport add hello-world
skillport add anthropics/skills skills              # shorthand format
skillport add anthropics/skills skills examples     # multiple paths
skillport add https://github.com/anthropics/skills/tree/main/skills/frontend-design

How it works: Your agent reads the skills table in AGENTS.md, then runs skillport show <id> to load full instructions.

Note: CLI mode requires skillport init in each project. Skills are added to the directory configured in .skillportrc. For multi-project use, consider MCP Mode.

Key Features

Deliver: MCP Server

Tools for progressive skill loading:

Tool	Transport	Purpose
search_skills(query)	stdio, HTTP	Find skills by task description
load_skill(skill_id)	stdio, HTTP	Get full instructions and filesystem path
read_skill_file(skill_id, file_path)	HTTP only	Read files (experimental)

stdio (default): The path from load_skill is accessible in the agent's execution environment-agents can read files and run scripts directly.

Streamable HTTP (experimental): For remote agents without filesystem access. Adds read_skill_file but is not fully tested yet.

Manage: CLI

Project Setup:

skillport init              # Initialize project (.skillportrc, AGENTS.md)
skillport doc               # Update AGENTS.md when skills change
skillport doc --all         # Update all instruction files in .skillportrc

Skill Management:

skillport add <source>      # GitHub URL, local path, zip file, or built-in name
skillport update [id]       # Update skills from original sources
skillport list              # See installed skills
skillport remove <id>       # Uninstall a skill
skillport validate [target] # Validate skills (ID, path, or directory)

# Override paths per run (CLI > env > default)
skillport --skills-dir ./skills add hello-world
# Place global flags before the subcommand (e.g., skillport --skills-dir ... add ...)

Search & Load:

skillport search <query>    # Find skills by description
skillport show <id>         # View skill details and instructions

Install from GitHub:

One command to install skills from any GitHub URL-no cloning required. Supports shorthand format, branches, and subdirectories:

# Shorthand format (owner/repo [paths...])
skillport add anthropics/skills skills              # specific path
skillport add anthropics/skills skills examples     # multiple paths (1 download)
skillport add owner/repo                            # repo root

# Full URL format
skillport add https://github.com/anthropics/skills/tree/main/skills
skillport add https://github.com/wshobson/agents/tree/main/plugins/developer-essentials/skills

# Private repos work automatically if you use GitHub CLI
gh auth login  # one-time setup
skillport add your-org/private-skills skills

Organize: Categories & Namespaces

Use metadata.skillport to:

• Search - category and tags improve discoverability
• Filtering - Control which skills each client sees
• Core Skills - alwaysApply: true for always-available skills

# SKILL.md frontmatter
metadata:
  skillport:
    category: development
    tags: [testing, quality]
    alwaysApply: true  # Core Skills - always available

Client-Based Skill Filtering:

Expose different skills to different AI agents:

{
  "mcpServers": {
    "skillport-development": {
      "command": "uvx",
      "args": ["skillport"],
      "env": { "SKILLPORT_ENABLED_CATEGORIES": "development,testing" }
    }
  }
}

{
  "mcpServers": {
    "writing-skills": {
      "command": "uvx",
      "args": ["skillport"],
      "env": { "SKILLPORT_ENABLED_CATEGORIES": "writing,research" }
    }
  }
}

Filter options:

• SKILLPORT_ENABLED_SKILLS - Specific skill IDs
• SKILLPORT_ENABLED_CATEGORIES - By category
• SKILLPORT_ENABLED_NAMESPACES - By directory prefix
• SKILLPORT_CORE_SKILLS_MODE - Skills visible to agent without searching (auto/explicit/none)

Scale: Progressive Disclosure

The Problem:

System Prompt (every conversation):
├── Company guidelines (2,000 tokens)
├── Coding standards (3,000 tokens)
├── Review checklist (1,500 tokens)
├── 50 more instructions...
└── Total: 30,000+ tokens before you say "hello"

The Solution: Skills load progressively - metadata first, full instructions on demand:

Stage	Tokens	When
Metadata	~100/skill	Always (searchable)
Instructions	~5,000	On load_skill()

100 skills = ~15K tokens (vs 300K+ if all loaded upfront)

SkillPort enhances this with:

• BM25 search - Find the right skill without loading all metadata
• Per-client filtering - Expose only relevant skills to each agent
• Fallback chain - FTS → substring (always returns results)

Design: Path-Based Execution

SkillPort provides knowledge, not a runtime. Instead of executing code, it returns filesystem paths:

# load_skill returns:
{
    "instructions": "How to extract text from PDFs...",
    "path": "/Users/me/.skillport/skills/pdf-extractor"
}

The agent executes scripts directly:

python {path}/scripts/extract.py input.pdf -o result.txt

Context Engineering: Executing code doesn't require reading code.

Approach	Context Cost
Read script → execute	~2,000 tokens
Execute via path	~20 tokens

This keeps SkillPort simple and secure-it's a harbor, not a runtime.
