Phase 1 sample plugin synthesizing a SKILL.md frontmatter for backwards-compat tests.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Sample Plugin This is the SKILL.md half of the Phase 1 e2e fixture. The companion `open-design.json` sidecar carries the canonical OpenDesign 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.

How to install
mdr add nexu-io/open-design/sample-plugin@sha256:32a0db454a1e17c0The line at the top of this page pins the label git:20260818.f1a0b60, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
