Use this skill when C++ code must choose, implement, or review an error-reporting strategy: exceptions, std::expected/result types, std::error_code, status enums, or a mix — and when exception-safety guarantees, rollback, or propagation across boundaries are in question. std::expected requires C++23; pre-C++23 codebases substitute an equivalent result type (tl::expected, boost::outcome, absl::StatusOr, or an in-house one), and every expected mention in this skill covers those equivalents.
Cpp Error Handling Design is a community-contributed Claude Code skill in the code-quality sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/cpp-error-handling-design/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when: designing, reviewing, or refactoring C++ error handling policy, exceptions vs std::expected vs error codes, exception safety guarantees (basic, strong, nothrow), RAII rollback, noexcept and move semantics interactions, error propagation across module or ABI or thread or coroutine boundaries, std::error_code categories, terminate paths, or destructor and swap exception rules.
The Cpp Error Handling Design Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 174,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
