Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
What it does
This skill enhances the handling of validation errors generated by the z-schema library. It allows AI agents to inspect, filter, map, and present these errors in a user-friendly way. Specifically, it focuses on processing ValidateError objects, which contain detailed information about each individual error within the .details array. This skill enables graceful management of validation failures and provides actionable feedback based on schema validation results.
When to use it
- When validating data against a
z-schemaschema and needing to provide specific error messages to users or systems. - In situations where you want to extract key information (like the error code, path, and message) from complex
ValidateErrorobjects. - To create custom error reporting workflows based on the details contained within a
z-schemavalidation failure.
Key capabilities
- Inspects
ValidateErrorobjects returned byz-schema. - Accesses individual
SchemaErrorDetailelements within the.detailsarray of aValidateError. - Extracts specific error information such as: message, code, parameters, path, keyword, and schema details.
- Supports both "try/catch" (default) and "safe mode" for error handling.
Example prompts
- "Show me the paths of all validation errors."
- "Extract the error codes from this z-schema validation failure."
- "Format this
ValidateErrorobject into a human-readable report."
Tips & gotchas
- Requires the
z-schemalibrary to be installed and used for data validation. - The skill works with both "try/catch" and "safe mode" error handling approaches offered by
z-schema. Choose the appropriate method based on your application's needs. - Error details are structured within a
.detailsarray, so iterating through this array is necessary to access individual error messages and information.
