Which tools does the skill use to scan code?

The skill utilizes Read, Grep, and Glob tools to efficiently search through your source files for problematic error-handling patterns.

Does this skill support Japanese development environments?

Yes, it is specifically configured to trigger on Japanese terms like 'エラーハンドリング' (error handling) and '握りつぶし' (swallowed errors).

How does this skill detect swallowed errors?

It scans for specific patterns like 'catch (e) {}', unhandled '.then()' chains, and optional chaining that may hide unexpected null values without reporting them.

What is a 'silent failure' in frontend development?

A silent failure occurs when code encounters an error but 'swallows' it (e.g., an empty catch block), preventing the system from logging the issue or notifying the user.

Can it help with React Error Boundaries?

Yes, it identifies code paths that lack proper UI error states and suggests implementing Error Boundaries or feedback components.

安全与测试

Identifies and mitigates silent failures, swallowed errors, and unhandled exceptions in frontend codebases.

关于

The Reviewing Silent Failures skill helps developers improve application observability by detecting patterns where errors are suppressed without proper logging or user feedback. It scans codebases for risky patterns like empty catch blocks, unhandled promises, and silent fallbacks in nullish coalescing. By providing standardized correction patterns, it ensures that exceptions are surfaced to monitoring tools and users, reducing the time spent debugging hidden issues and improving overall software reliability.

主要功能

Detects empty catch blocks and swallowed exceptions (SF1)
Flags missing error UI states and Error Boundary implementations (SF3)
Suggests standardized refactoring patterns for error logging and reporting
Identifies missing error handling in async functions and promises (SF2)
Pinpoints silent fallbacks in nullish coalescing and optional chaining (SF4)
3 GitHub stars

使用场景

Auditing legacy frontend repositories for hidden bugs and suppressed errors
Improving application observability by converting console logs to structured error reporting
Ensuring new features include proper error reporting and user-facing feedback
