Validate requests at the boundary with schemas, reject unknown fields, and return errors clients can act on. Use when hardening API input handling or standardizing validation across endpoints.
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
# Request validation Validate once, at the edge, into a typed value the rest of the code can trust. Everything past the boundary should be impossible to construct invalid. ## Method 1. **Schema-first, one schema per endpoint.** Define the request shape declaratively (JSON Schema via OpenAPI, zod, pydantic) and derive both the validator and the documentation from it. Hand-rolled if-chains drift from docs within a sprint. 2. **Parse, don't just check.** The validator's output is a typed object (trimmed strings, parsed dates, enum members), not the raw JSON plus a boolean. Downstream code taking `dict`/`any` re-validates forever. 3. **Reject unknown fields on writes.** A typo'd optional field (`descripton`) silently accepted is data loss the client discovers weeks later. Strictness on request bodies; tolerance is for what you read from others (be conservative in what you send, but validate what you accept). 4. **Layer the checks.** Shape and types (schema), then domain rules (ranges, formats, cross-field: `end > start`), then stateful rules (uniqueness, existence, permissions) inside the transaction where they …

How to install
mdr add amey-thakur/ai-skills/request-validation@sha256:81a5c4555a8d3f46The line at the top of this page pins the label git:20260720.1dc980e, 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.
