Comprehensive unit testing framework for Bash and POSIX shell scripts using ShellSpec with TDD/BDD best practices. Use when writing tests for shell scripts, debugging test failures, refactoring scripts for testability, setting up test infrastructure, mocking external dependencies, or implementing test-driven development for Bash/shell projects. Covers test structure, isolation, mocking, output capture, coverage, CI integration, and troubleshooting.
Evaluate how well a codebase supports autonomous AI development. Analyzes repositories across nine technical pillars (Style & Validation, Build System, Testing, Documentation, Dev Environment, Debugging & Observability, Security, Task Discovery, Product & Analytics) and five maturity levels. Use when users request `/readiness-report` or want to assess agent readiness, codebase maturity, or identify gaps preventing effective AI-assisted development.
Write, critique, and iterate prompts for OpenAI GPT-5 series models. Use for tasks like: (1) turning vague requirements into high-signal instructions, (2) selecting between quick vs deep reasoning behaviors, (3) creating robust structured-output prompts (JSON schemas, tool calls), (4) designing evaluation prompts and rubrics, and (5) debugging prompt failures (hallucinations, format drift, tool misuse). Trigger when the user mentions GPT-5, prompt engineering, system/developer messages, structured outputs, agent prompts, or wants best-practice templates.
