Use when asked to audit the type modelling of beady-eye's Claude Code plugin — whether its domain types are honest, whether they can represent illegal states, or for a periodic model-level type review. Triggers on "audit our type modelling", "are our types honest", "can our types represent illegal states", "model-level type review", "audit our domain types". The judgement sibling to effect-native-audit: a workflow-driven reasoning sweep over the plugin's domain types, not an anchored…
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
# Effect-model type audit This skill sweeps the domain types of the plugin under `plugin/` for model-level dishonesty. A type is dishonest when its shape lets a caller build a value the domain does not mean, or forces a caller to fake one. The question is whether the type's value space matches the domain's, and whether all its producers and consumers mean the same thing by it. Four lenses ask about the value space, each against each family of types: - **L1 Illegal-representable.** Can the type represent a value that is invalid in the domain? A combination of fields, an optional that should be required, a bare primitive admitting an out-of-domain string, or a pair of booleans with a meaningless fourth corner. Invalid state must be unrepresentable. - **L2 Under-expressive.** Is there a legal domain state the type cannot represent? The missing case shows up as a sentinel, a placeholder, an impossible branch, or a comment apologising for a field that is "always absent here". - **L3 Role coherence.** Do all the type's construction sites and read sites mean the same thing by it, or does it serve two roles under one name? An …

How to install
mdr add codeforbreakfast/beady-eye/effect-model-audit@sha256:c94186e261d86e9aThe line at the top of this page pins the label git:20261006.5d17c97, 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.
