@lythos/hello-world

The thinnest possible lythoskill skill. A single SKILL.md and a one-line sanity-check CLI. Use as a template when starting a new skill from scratch.

Why

Not every skill needs complex logic, dependencies, or build steps. The thinnest possible skill is a single SKILL.md with YAML frontmatter — intent, usage, and constraints. This package demonstrates that minimal form and adds a trivial CLI for sanity-checking your toolchain.

Install

bun add -d @lythos/hello-world
# or use directly
bunx @lythos/hello-world

Quick Start

# Sanity-check: does the thin-skill ecosystem work?
bunx @lythos/hello-world
# → ✅ Hello from lythoskill-hello-world! The thin-skill ecosystem works.

# Use the SKILL.md as a template for your own skill
cp -r node_modules/@lythos/hello-world/skill ./skills/my-skill

Commands

| Command | Description | |---------|-------------| | (no args) | Prints a sanity-check confirmation message |

Skill Documentation

This package is primarily a Skill layer template — the agent-visible documentation is here:
packages/lythoskill-hello-world/skill/SKILL.md

The CLI exists only as a minimal smoke test. The real value is the SKILL.md structure.

Architecture

Part of the lythoskill ecosystem. This is the thinnest possible complete package — it has a Starter layer (the one-line CLI) and a Skill layer (the SKILL.md), but both are intentionally minimal.
