Apply the MSW Kernel to a markdown document — a plan, spec, skill, prompt, or any other .md file. Derives the document's contract, judges every claim by the kernel's deletion test, deletes the claims that fail, audits every limit for authority, and reports in the kernel's format. Use when explicitly invoked with a file, or when the user asks to apply MSW, run the MSW deletion test, or strip a document down to what its contract actually requires. Edits the target in place — for prompt-guide…
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.
What the file says
# valcraft-msw Never replay another Valcraft skill's report. Omit unrelated prior state. When relevant prior state is necessary, summarize it in one prose paragraph containing only the prior outcome, exact target, relevant blocker or handoff, and one suggested next action. The suggested action is advisory and grants no authority. Apply the MSW Kernel to one markdown document. The document's claims face the kernel's deletion test against the document's own contract; the result is reported in the kernel's report format. MSW deletes failed claims and makes only the minimal structural repairs those deletions force. It does not add substantive content or rewrite surviving claims. Claude Code `/valcraft:valcraft-<name>`; Codex `$valcraft:valcraft-<name>`; OpenCode `valcraft-<name>`; Cursor `/valcraft-<name>`. The kernel is defined in `references/kernel.md`. Read it before judging; apply it as written — its contract definition, deletion test, limits rule, and fuses govern this skill and are not restated here. Never paraphrase the kernel or substitute your own necessity criteria. …

How to install
mdr add valzav/valcraft/valcraft-msw@sha256:020601a45fdf838dThe line at the top of this page pins the label git:20260929.54ed5b5, 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.
