Jules issues we find in JavaScript projects
Problems specific to Jules's code generation patterns when building JavaScript apps.
PRs may conflict with concurrent team changes
Jules works asynchronously on tasks that may take hours. While it's working, your team continues committing. The resulting PR can conflict with merged changes in ways that are complex to resolve.
Security-sensitive PRs need careful human review
Jules implements security fixes and auth changes autonomously. Without careful review, a PR that looks correct can introduce subtle security regressions in adjacent code paths.
Jules may not understand implicit project conventions
Jules reads your codebase but can miss undocumented team conventions — naming patterns, error handling styles, and architectural decisions that aren't expressed in code.
Async PR scope may be too narrow or too broad
Jules interprets task descriptions literally. A fix for one bug may miss related bugs in the same module, or conversely, a feature request may result in sweeping changes you didn't intend.
JavaScript issues we check for
Common JavaScript problems that affect production readiness.
Prototype pollution
AI-generated code merges user-supplied objects into prototypes via Object.assign or spread operators without sanitization, enabling property injection attacks.
Loose equality comparisons
Using == instead of === leads to type coercion bugs where '0' == false, null == undefined, and other non-obvious truthy/falsy comparisons cause silent logic errors.
Unhandled promise rejections
Async functions without try/catch or .catch() handlers cause unhandled rejection warnings and silent failures in production.
Global variable leaks
Missing 'const' or 'let' declarations create implicit globals that pollute the global scope and cause unpredictable behavior across modules.
