bash-defensive-patterns

Quick Review

Excellent comprehensive skill for defensive Bash programming. The description clearly indicates when to use this skill (CI/CD, production scripts, system utilities). Task knowledge is outstanding with 10 practical patterns covering strict mode, error trapping, argument parsing, logging, signal handling, and idempotency—complete with ready-to-use code snippets. Structure is very good: clear sections progress from core principles to fundamental patterns to advanced techniques, though with 10+ patterns in one file it borders on dense (still manageable given the code-heavy nature). Novelty is solid: while individual techniques exist in documentation, this curated collection of production-grade defensive patterns with integrated examples meaningfully reduces the token cost and research time a CLI agent would need to write robust Bash scripts. A CLI agent would struggle to synthesize this comprehensive defensive approach from scratch across multiple sources. Minor improvement possible: could separate patterns into individual reference files for very complex projects, but current structure works well for the domain.
