SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the challenge of identifying "silent failures" in software, where errors occur without explicit error messages or visible exceptions, potentially leading to subtle bugs and system instability.

Core Features & Use Cases

Subagent Execution: Leverages a specialized silent-failure-hunter agent card for focused analysis.
Error Handling Audit: Helps in auditing code for weak or missing error handling mechanisms.
Use Case: When a feature is not behaving as expected but no errors are logged, use this Skill to investigate potential silent failures in the underlying code.

Quick Start

Run the silent-failure-hunter subagent with the task context for the current project.

FAQPage Schema

How do I detect silent failures in my codebase during a code review?▼

You can detect silent failures during a code review by running a dedicated subagent that analyzes your codebase to identify weak error handling and non-obvious bugs without explicit exceptions.

Why does my feature not work but no errors are logged?▼

Features failing without logged errors often indicate silent failures in the underlying code, which happen when errors occur without explicit messages or visible exceptions. Auditing your code for missing error handling can locate these bugs.

Do I need the codex-subagent CLI tool to investigate missing error handling?▼

Yes, investigating missing error handling requires the codex-subagent CLI tool, because the analysis is executed by invoking a dedicated subagent card through that specific command-line interface.

What is the best way to audit code for weak error handling proactively?▼

The best way to proactively audit code for weak error handling is to execute a specialized subagent designed to hunt for silent failures, identifying system instability risks before they manifest as subtle bugs.

Does silent failure detection work for debugging sessions?▼

Yes, silent failure detection works for debugging sessions by analyzing your project's task context to find non-obvious bugs where errors occur without visible exceptions or explicit error messages.
