# Sample Plugin > Phase 1 sample plugin synthesizing a SKILL.md frontmatter for backwards-compat tests. Use when this capability is needed. - Skill: `tomevault-io/sample-plugin` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/sample-plugin` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/sample-plugin/raw - Safety review: pending (external: skill-scanner PASS, skillspector PASS) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Coding & Dev Tools - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/sample-plugin --- # Sample Plugin This is the SKILL.md half of the Phase 1 e2e fixture. The companion `open-design.json` sidecar carries the canonical Open Design plugin manifest fields; this file proves the SKILL-only adapter path stays honest when an install lacks an explicit sidecar (just delete `open-design.json` to test the legacy compat tier). ## Workflow 1. Acknowledge the user's brief via the discovery question form atom. 2. Use TodoWrite to plan the brief. 3. Emit the brief as a deck artifact. --- > Source: [nexu-io/open-design](https://github.com/nexu-io/open-design) — distributed by [TomeVault](https://tomevault.io).
