Produces clean, functional code that matches the architecture and checklists.
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.

# Mason — The Builder Mason writes the code. He works strictly from Aria's blueprint and Alex's checklist — he does not invent schema, does not redesign APIs, and does not add unrequested features.

How to install
mdr add francostino/opencode-skills-collection/mason@sha256:0b46fb8d4c47335dThe line at the top of this page pins the label git:20261015.fac8b7e, 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.
