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

# z-spec (formal Z specifications)

z-spec type-checks Z specifications with fuzz, model-checks and animates them
with ProB, and renders them in lux. This doc is how an *agent* drives z-spec in
this repo — not how to develop z-spec itself.

z-spec is per-repo: its MCP tools and its lux menu entries are live only where
someone ran `z-spec enable` and committed `.punt-labs/z-spec/enabled`. In a repo
with no marker every MCP tool except `enablement` declines with a one-line
message naming the enable command, and z-spec contributes no lux menu entries.
The `z-spec` CLI is never gated — a shell invocation is deliberate by
definition.

## Enabling z-spec in a repo

- `/z-spec:enable` (or `z-spec enable`) — turn z-spec on here: deposit this
  guide, write the marker, add the `@`-import line to the repo `CLAUDE.md`.
  Idempotent; re-running is also the upgrade path.
- `/z-spec:disable` (or `z-spec disable`) — turn it off: prune the import line
  and delete the marker. The `.punt-labs/z-spec/` subtree is left dormant, never
  deleted.

Neither surface runs git. The marker is a tracked file: commit it in a PR so
enablement is reviewed and identical for everyone who clones.

How to install

The exact contents, by fingerprint

mdr add punt-labs/vox/.punt-labs/z-spec/CLAUDE.md@sha256:e7c4bd4d488a42c5

The line at the top of this page pins the label git:20260824.16b8883, 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.
