Claude agent skill

The Starsystem skill teaches your AI agent how to operate ss — provision services, register domains, manage vault credentials, deploy to cloud providers, and use the MCP tools — without you having to explain the API each time.

Once installed, the agent automatically uses the skill whenever you ask it to do anything infrastructure-related.

Install

Claude Code — personal (all projects)

mkdir -p ~/.claude/skills/starsystem
curl -o ~/.claude/skills/starsystem/SKILL.md \
  https://docs.celestialintelligence.com/skills/starsystem.md

Takes effect immediately in the current session — no restart needed.

Claude Code — this project only

mkdir -p .claude/skills/starsystem
curl -o .claude/skills/starsystem/SKILL.md \
  https://docs.celestialintelligence.com/skills/starsystem.md

Commit .claude/skills/starsystem/SKILL.md to share it with your team.

Cursor

mkdir -p .cursor/skills/starsystem
curl -o .cursor/skills/starsystem/SKILL.md \
  https://docs.celestialintelligence.com/skills/starsystem.md

Kilo Code

mkdir -p .kilo/skills/starsystem
curl -o .kilo/skills/starsystem/SKILL.md \
  https://docs.celestialintelligence.com/skills/starsystem.md

OpenCode

mkdir -p .opencode/skills/starsystem
curl -o .opencode/skills/starsystem/SKILL.md \
  https://docs.celestialintelligence.com/skills/starsystem.md

OpenCode also loads .claude/skills/ automatically, so the Claude Code project install works here too.

Antigravity

mkdir -p .agent/skills/starsystem
curl -o .agent/skills/starsystem/SKILL.md \
  https://docs.celestialintelligence.com/skills/starsystem.md

Windsurf

Windsurf uses a single rules file rather than a skills directory:

curl -s https://docs.celestialintelligence.com/skills/starsystem.md >> .windsurfrules

Codex

# Personal — applies to all projects
curl -o ~/.codex/AGENTS.md \
  https://docs.celestialintelligence.com/skills/starsystem.md

# Project-level
curl -o AGENTS.md \

What it teaches your agent

Once installed, your agent knows how to:

Provision infrastructure — Neon, Supabase, Fly, Railway, Cloudflare, AWS, local processes
Register domains and wire DNS — Porkbun domain registration with automatic DNS record wiring
Browse the provider catalog — compare pricing tiers across Neon, Hetzner, Porkbun, and 30+ SaaS services
Manage vault credentials — store and reference secrets safely without exposing values
Use MCP tools — the full starsystem_* tool set, in the right order
Write correct YAML — service types, provider names, vault ref syntax, depends_on ordering

Example prompts after installing

Register myapp.io through Porkbun and point it at my Fly app

Set up a Neon database for the staging environment

What providers are available for object storage and what do they cost?

Deploy the api service to Fly and wire the domain DNS automatically

Check which vault credentials are missing before I deploy

Staying up to date

The skill file is updated alongside each Starsystem release. To update, re-run the original install command for your IDE.
