Use after code changes to choose and run validation commands for Node, JavaScript, TypeScript, Python, Go, Dart, Java, Kotlin, C++, Swift, or Objective-C projects. Prefer project-defined commands and report skipped checks and risks.

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

# Project Validation Skill

Use this Skill after code changes.

## General Rules

- Prefer commands already defined by the project.
- When `rtk` is available, prefer `rtk` for non-reporting commands; for unit tests, API / integration tests, Playwright Web E2E, Maestro Mobile / Hybrid E2E, or any command that must generate report files, first apply the `rtk` and reporting-test Gate.
- Do not bypass project configuration.
- Do not modify lock files unless required by the task.
- If full checks are expensive, run focused checks first.
- State which checks were skipped and the remaining risks.

## `rtk` and Reporting-Test Gate

`rtk` is a command-output compression layer, not a test runner. Before executing validation commands, first distinguish between “only terminal facts are needed” and “file side effects must be produced.”

- lint, typecheck, static analysis, build, read-only checks, or diagnostic commands that do not depend on persisted reports can generally prefer `rtk`.

How to install

The exact contents, by fingerprint
mdr add kunolu/640-skills/project-validation@sha256:f069456d5dc80dde

The line at the top of this page pins the label git:20261014.5b97c82, 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.
