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 enables AI agents to implement JavaScriptCore (JSC) classes using C++ within the Bun runtime environment. It allows developers to extend or modify the core JavaScript engine by defining custom native classes directly in C++.
When to use it
- You need to create high-performance native modules that interact deeply with the Bun runtime internals.
- You are building a custom interpreter extension requiring direct access to JSC class definitions.
- You want to optimize specific JavaScript operations by offloading logic to compiled C++ code.
- You are developing low-level tools for the Bun ecosystem that require engine-level modifications.
Key capabilities
- Define and implement native JavaScriptCore classes using C++.
- Integrate custom logic directly into the Bun runtime execution context.
- Leverage the performance benefits of compiled code for engine extensions.
- Access low-level APIs provided by the JSC library within Bun.
Example prompts
- "Write a C++ implementation for a new JSC class that handles custom memory management in Bun."
- "How do I extend the JavaScriptCore engine in Bun to add a native function using this skill?"
- "Create a C++ module that defines a specific JSC class to optimize data serialization in my Bun app."
Tips & gotchas
Ensure you have a solid understanding of both C++ and the JavaScriptCore architecture before attempting implementation, as errors can destabilize the runtime. This skill is specialized for advanced development; standard JavaScript APIs should be preferred unless native performance or engine access is strictly required.
