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 12 Oct 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 assistant-ui/skills at 1ba8e9105c.
The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

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 primitives skill provides foundational building blocks and basic operations that AI agents can use to perform fundamental tasks. It includes core functionalities such as data manipulation, simple logic execution, and basic input/output handling.

When to use it

When you need to implement basic computational logic in an AI agent.
For initializing or setting up a new AI agent with essential tools.
When working on projects that require minimal dependencies but rely on core operations.
To build more complex skills by combining primitive functions.

Key capabilities

Data type handling (e.g., strings, numbers).
Basic arithmetic and logical operations.
Input parsing and output formatting.
Simple conditional execution.

Example prompts

"Add 5 to the number 10."
"Check if 'hello' is equal to 'world'."
"Format the string 'Hello, {name}' with the name 'Alice'."

Tips & gotchas

Ensure that your AI agent has access to the primitives skill before attempting complex operations.
While it provides essential functions, more advanced tasks may require additional skills or custom code.
