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 provides alternatives to using index signatures in TypeScript. Index signatures can be verbose and less type-safe, so this skill offers more concise and maintainable approaches for defining object types with dynamic keys. It helps developers write cleaner, more expressive TypeScript code by suggesting better patterns than relying on index signatures.
When to use it
- When refactoring existing TypeScript code that heavily uses index signatures.
- When designing new TypeScript interfaces or types where the keys are known at runtime but not compile time.
- To improve the readability and maintainability of complex object type definitions.
- For projects aiming for stricter type safety beyond what index signatures provide.
Key capabilities
- Suggests alternatives to index signatures.
- Provides more concise type definitions.
- Enhances code readability.
- Improves type safety.
Example prompts
- "Can you suggest a better way to define this TypeScript type that uses an index signature?"
- "I have this object with dynamic keys; how can I represent it in TypeScript without using an index signature?"
- “Refactor this code snippet, replacing the index signature with a more robust alternative.”
Tips & gotchas
This skill assumes a basic understanding of TypeScript and its type system. While it offers alternatives, evaluating their suitability requires considering specific use cases and potential trade-offs in terms of flexibility versus type safety.
