How to use Kubernetes & GitHub Actions Manifest Linter

Run pinned offline structural checks for Kubernetes resources or GitHub Actions workflows and surface precise paths.

1. Paste, type, or drag and drop a supported text file into the input area.
2. Choose the options that match your intended result.
3. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

What the result means

A resource/job summary plus errors and security-focused warnings.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

• Everything is processed in this browser tab. Input, filenames, keys, and output are never uploaded or saved. CRDs, admission policies, expressions, reusable workflows, cluster versions, and hosted-service behavior require their authoritative validators.
