Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned 28 Sept 2026

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.
Pinned to a commit: passed
Scanned callstackincubator/agent-skills at 61e6e7dfdf.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

Scanned: 1 file, 61 lines

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

The validate-skills skill checks the validity of AI agent skills, ensuring they meet specific criteria such as syntax correctness and functional completeness. It helps identify potential issues before deployment, improving reliability and performance.

When to use it

Before deploying a new AI agent skill to ensure it is error-free.
When troubleshooting an existing skill that may be causing unexpected behavior.
During the development phase to catch errors early in the process.
As part of a continuous integration pipeline for automated validation checks.

Key capabilities

Syntax validation for AI agent skills
Functional completeness checks
Error detection and reporting

Example prompts

"Validate this skill for syntax and functionality."
"Check if the AI agent skill is ready for deployment."
"Run a full validation on the latest version of the skill."

Tips & gotchas

Ensure that the skill being validated is in the correct format as specified by the registry.
Validation may not catch logical errors, only syntax and structural issues.
