Reuse Existing Libraries Before Writing Custom Code

Custom helpers can duplicate existing functionality and increase maintenance work. This skill guides library discovery and direct reuse before implementing only the missing behavior.

Test it

Using "dont-it-yourself". Should I write a helper for grouping records?

Expected outcome:

  • Check whether the repository already provides a grouping utility.
  • The reference recommends es-toolkit for grouping operations.
  • Use the existing function directly when it satisfies the requirement.

Using "dont-it-yourself". How should I choose an Effect client for an external service?

Expected outcome:

  • Check whether a generated @distilled.cloud SDK exists for the service.
  • If none exists, check for a published OpenAPI specification and assess @effect/openapi-generator.
  • Implement only behavior that the selected client and its extension options cannot provide.

Using "dont-it-yourself". Search summaries do not show a package for my requirement. Should I build it?

Expected outcome:

  • Inspect the candidate repository packages and npm scope listings directly.
  • Search using relevant standards, format names, and data names.
  • Compare maintained candidates before deciding that custom implementation is necessary.

All six static findings are false positives: Markdown code spans, a provenance URL, and readable Japanese documentation explain the detections. No evidence found of executable payloads, credential exfiltration, obfuscation, or prompt injection in the three reviewed files.

What You Can Build

Replace Duplicate Helpers

Check existing dependencies before adding grouping, validation, date, or retry helpers.

Plan an API Integration

Look for an existing Effect SDK or an OpenAPI generation route before writing a custom client.

Review Abstraction Choices

Identify forwarding wrappers and separate necessary custom behavior from functionality available in maintained libraries.

Try These Prompts

Find a Reusable Utility 
I need [operation] in [project]. Check existing dependencies and the library reference before suggesting a new helper.
Compare Library Candidates 
Find existing solutions for [requirement]. Search Effect modules, repository dependencies, and npm. Compare maintenance, types, and dependency counts.
Review a Proposed Wrapper 
Review [function or proposal]. Identify forwarding wrappers, recommend direct calls, and reserve custom code for missing behavior. Check extension APIs first.
Plan an Effect API Client 
Plan an Effect integration for [service]. Check @distilled.cloud SDK availability, then published OpenAPI generation options. Identify gaps without inventing package availability.

Best Practices

  • Inspect existing modules and dependencies before searching npm or adding custom code.
  • Verify candidate package listings directly instead of relying only on search summaries.
  • Check maintenance, types, dependencies, security, and licensing before adopting a package.

Avoid

  • Writing a helper before checking existing implementations.
  • Adding wrappers that only forward calls without required behavior.
  • Assuming a missing search summary result proves that no suitable package exists.

Frequently Asked Questions

Does this skill install packages automatically?
No. The supplied files provide guidance and recommendations, not an installer or executable automation.
Which ecosystem does it emphasize?
The references emphasize Effect, TypeScript, npm, and React, alongside runtime APIs such as Web Crypto.
Where does the search process begin?
It begins with Effect modules, then existing repository dependencies, and finally npm.
Is custom implementation always prohibited?
No. The skill permits writing missing behavior and prefers extension APIs or options when available.
How does it compare package candidates?
It favors maintained packages with type definitions and fewer dependencies, and recommends inspecting complete package listings.
Does a recommendation guarantee package security?
No. The skill does not provide vulnerability checks or a dependency security review process. Evaluate each package before adoption.
