What it does
dont-reinvent is a Claude skill that checks whether an existing package or service already covers a task before the agent writes new code. It compares free, build and buy options, and it vets candidates for license, maintenance and security instead of relying on star counts. It is meant for non-trivial code.
Use cases
- 01Checking for a library before writing a rate limiter
- 02Comparing build and buy options for a feature
- 03Reviewing the license and upkeep of a package
