upskilled

Claude, upSKILLed.

Generate Claude skill files for any API or CLI tool — in seconds.

What it does

upskilled generates a complete Claude skill package (3 files) from:

• A curated API service (GitHub, Notion, Slack, Linear, Stripe, and more)
• A curated CLI tool (ffuf, nmap, gobuster, sqlmap, gh cli, and more)
• A plain English description of any tool or API
• Raw --help output from any CLI tool

Installation

npm install -g upskilled

Usage

upskilled --service github --use "manage issues and PRs"
upskilled --tool ffuf --use "fuzz web directories during recon"
upskilled --describe "a REST API for sending SMS" --use "send build alerts"
upskilled --help-output "$(ffuf --help)" --use "directory fuzzing"

Output

Every generation produces 3 files:

• {name}-skill.md — Claude skill file, ready to use in any Claude project
• {name}-config.json — Service configuration
• {name}-examples.md — 5–10 example prompts

Using your skill with Claude

After generating, load the skill into any Claude project:

1. Place the downloaded files somewhere in your project (e.g. .claude/skills/)
2. Reference the skill in your project's CLAUDE.md:

   @.claude/skills/{name}-skill.md

3. Claude loads the skill automatically at the start of each session

The skill.md file is what Claude reads. config.json and examples.md are supplementary — keep them alongside it for reference.

Requirements

• Node.js v18+
