# PackageBuilder Build conformant packages for the metafactory ecosystem. This skill encodes the conventions, governance rules, and quality requirements that live in the heads of the metafactory maintainers and across dozens of CLAUDE.md files, design decisions, and SOPs. This skill exists because metafactory faces the same scaling challenge the HuggingFace transformers-to-mlx team solved: how do you maintain quality when contributions outpace (or need to outpace) review capacity? The answer is the same architecture: encode conventions in a Skill, verify independently with a harness, make PRs self-documenting. ## When to Use Use this skill when: - Creating a new arc-installable package (skill, tool, agent, prompt, component, pipeline, action) - Preparing a package for submission to the metafactory registry - Reviewing whether a package meets ecosystem conventions - Onboarding as an Author-Builder and learning the conventions - Checking what makes a package "conformant" before submitting a PR Do NOT use this skill for: - Working on the metafactory registry itself (meta-factory repo) - Modifying arc, compass, or other infrastructure repos (those have their own conventions) - General development work that doesn't produce a distributable package ## Workflow Routing | Workflow | Trigger | File | |----------|---------|------| | **CreatePackage** | "build package", "create package", "new package", "author-builder onramp" | `Workflows/CreatePackage.md` | | **SubmitPackage** |
