This extracts hard-won debugging insights from your current conversation and saves them as reusable skills. The core idea is that skills aren't code snippets but decision-making heuristics: not "add this try/catch block" but "in async network code, wrap each I/O operation separately because failure between operations is the common case." It enforces a quality gate where skills must be non-Googleable, context-specific to your codebase (with actual file paths and line numbers), and represent real debugging effort. Mostly deprecated in favor of /oh-my-claudecode:skillify now, but the internal expertise section is interesting because it's designed to be self-improving while the workflow stays stable. Saves to project-level .omc/skills by default, user-level only for truly portable insights.
