The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
The skill contains runtime commands that run jscodeshift with remote transform scripts (e.g., https://raw.githubusercontent.com/reactjs/react-codemod/master/transforms/rename-unsafe-lifecycles.js, https://raw.githubusercontent.com/reactjs/react-codemod/master/transforms/update-react-imports.js, https://raw.githubusercontent.com/reactjs/react-codemod/master/transforms/error-boundaries.js) which are fetched at execution time and thus download and execute remote code as part of the required codemod workflow.
