Write and review Zog schema validation in Go: schema shape, Parse against Validate, required and default semantics, tests and transforms, issue handling, and the zhttp, zjson, and zenv adapters.
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
Zog is a Zod-shaped API over Go semantics, and the two disagree in ways that still compile. Import as `z "github.com/Oudwins/zog"`. Three biases decide most calls: - **A remembered Zod default is a defect until checked.** Fields are optional by default, `z.Enum` does not exist, and a schema key names a Go struct field rather than an input key. - **`Parse` and `Validate` disagree about what missing means**, and that disagreement decides which tests in a chain run at all. - **Zog panics on a schema its author built wrong, and never on input data.** A panic is a defect in the schema definition, fixed there. ## Schema Shape - **A `z.Shape` key names a Go struct field, never an input key.** The first letter is case-corrected, so `"name"` and `"Name"` both bind to `Name`. A key matching no field panics with `Struct Schema Definition Error ... missing expected schema key`. - **Struct tags map input keys and nothing else.** Resolution runs `json`, `form`, `query`, or `env` for the source in use, then `zog`, then the schema key as written. - **`z.Struct(...).Required()` and `.Optional()` compile and do nothing.** An optional nested struct needs …

How to install
mdr add xobotyi/cc-foundry/zog@sha256:715be7da2655cb56The line at the top of this page pins the label git:20260828.b2ef325, 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.
