README

Hypatia

Agent skills for system design. Give an AI coding agent a product idea or a set of requirements, and get back a traceable, technology-neutral architecture: requirements, drivers, a justified style, a high-level design, diagrams, integration contracts, security and reliability reviews, decision records, and a final review.

Everything lives in [system-design-skills/](system-design-skills/).

Quick start

You do not need to clone this repository. From the root of the project you want the skills in:

npx github:whitedwarf7/Hypatia --target github

That installs all fourteen skills into `.github/skills/` of the current directory, with their shared references bundled so each skill is self-contained. Add `--dry-run` first if you want to see the plan.

If you have cloned this repository, the same installer runs locally:

cd system-design-skills
node scripts/install-skills.mjs --dir /path/to/your/project --target github

Target	Location	Agents
`github`	`.github/skills/`	GitHub Copilot in VS Code, Copilot CLI, Copilot coding agent
`agents`	`.agents/skills/`	Agent Skills standard consumers
`claude`	`.claude/skills/`	Claude Code and compatible agents
`user-copilot`, `user-agents`, `user-claude`	`~/.copilot`, `~/.agents`, `~/.claude`	The same agents, for every workspace

Add `--dry-run` to preview, `--update` to refresh an earlier install, `--skill a,b` for a subset, and `--list-targets` to print the full list. The installer needs Node.js 22.13+ and never overwrites a directory it did not create. Installed skill directories are ignored by git, so install wherever you like without dirtying the repository.

`npx github:` uses git under the hood to fetch into npm's cache, never into your project. Without git, download the repository archive from GitHub and run `bin/install-skills.mjs` from the extracted folder instead.
