building-plugins skillA

building-plugins is agent-read markdown (skill) from protolabsai/protoagent: Use this when asked to build, create, write, scaffold, or publish a protoAgent plugin — e.g. "make a plugin that …", "add a plugin for X", "package this as a plugin", "write a plugin that adds a tool/dashboard/workflow", "publish a plugin so others can install it". Covers the plugin contract (manifest + register()), the full contribution surface (tools, subagents, SKILL.md skills, workflows, console views, routes, MCP servers, config/secrets/settings), the conventional repo layout, testing, and .

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add protolabsai/protoagent/building-plugins@git:20260820.e235475
Exact content
mdr add protolabsai/protoagent/building-plugins@sha256:f79933a461b07026

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
