publish-step0

To validate murder-mystery prerequisite files before publishing, run a prerequisite evaluation that checks directory and file existence, detecting madamisu output via _meta.md or standalone Markdown content, then writes results to step0_prerequisites.md.

When prerequisite Markdown metadata is missing, workflow gating triggers an agent-based checking mechanism that evaluates the input directory, writes a step0 report to the working directory, and blocks publishing progress until required items are present.

You do not strictly need madamisu output files for prerequisite validation. The skill supports two recognition modes: detecting prior madamisu output via _meta.md, or processing standalone user-provided Markdown content packages.

Your game publishing workflow blocks progress at step 0 because prerequisite validation enforces directory and file existence checks, ensuring required game-setting or timeline Markdown files are complete before continuing to prevent broken outputs.

Yes, you can use standalone Markdown content for publish prerequisite validation. The skill detects whether the input is prior madamisu output via _meta.md or a standalone user-provided package and applies the appropriate validation logic.
