This skill exists to verify Claude Code SKILL.md compatibility from an MDA-compiled output.
Three things are true if you can see this skill listed in your Claude Code session:
SKILL.md parses under Claude Code's loader.name matches the package directory name (spec §06-2.1).allowed-tools field reaches Claude Code where it can be honored.Source: compat/claude-code/source.mda. Compile: mda compile compat/claude-code/source.mda --target SKILL.md --out-dir compat/claude-code/build --integrity.
What this does NOT prove:
when_to_use, model, effort, context, hooks, paths, shell, agent, argument-hint, arguments, disable-model-invocation, user-invocable). Those are out of v1.0 scope and earmarked for v1.1.metadata.mda.* (it does not, and is not required to).Other measured skills in the registry, with their headline benchmark lift.
