Delivers a small, bounded code change through inspection, a mini-plan, implementation, testing, review, and adversarial verification. Use for bug fixes, configuration changes, and features expected to touch no more than five files.

Suggests testing HPA axis functionality before and after starting GH replacement in patients not receiving glucocorticoid replacement with apparently normal pituitary-adrenal function. Triggers include initiating GH replacement in a GHD patient who is not on glucocorticoids and has normal adrenal function.

Run mutation testing against a project's test suite to verify the tests actually catch failures when source code is broken. Use after major test changes, before declaring a suite "good", or when coverage % looks healthy but you suspect tests aren't catching real bugs.

Builds React 18+ components, implements custom hooks, debugs rendering issues, migrates class components to functional, and manages state with Context, Redux, or Zustand. Covers React 19 Server Components, Suspense boundaries, useActionState forms, and performance optimization.

Provides a formal evaluation framework for Claude Code sessions, implementing eval-driven development (EDD) principles to define pass/fail criteria, measure reliability with pass@k metrics, and create regression test suites.

Trace every user-facing button through its full state change sequence to find bugs where functions individually work but cancel each other out, produce wrong final state, or leave the UI inconsistent.

Generates comprehensive unit tests with edge cases, error paths, and boundary values. Auto-detects the test framework, scans for untested functions, adopts existing conventions, runs tests, and self-heals failures in up to 3 iterations while measuring coverage.

Trigger: chrome-devtools, browser automation, headless browser, web scraping, inspect element, chrome debugger, inspect page, network request, console logs. Scope: Interact with and automate headless Chrome via Chrome DevTools Protocol (CDP) for testing, debugging, and scraping. Boundary: Do not use for macOS native desktop GUI automation (use peekaboo instead).

Manage your Prowlarr indexer hub from the terminal. List and inspect indexers, view query/grab statistics, check health, manage connected *arr applications and download clients, browse search history, and test indexer connectivity.

Use for writing, reviewing, debugging, or testing Python command-line interfaces built with Typer, including typed arguments and options, command groups, callbacks, contexts, exit behavior, help, and CliRunner tests. Do not use merely for terminal styling, arbitrary business logic, a Click-only CLI, shell scripts, or invoking an existing command.

Run structured What-If scenario analysis with 4-6 branch possibility exploration (best, likely, worst, wild card, contrarian, second-order). Use for speculative questions about uncertain futures, strategic forks, contingency planning, or stress-testing decisions.

Test generation is repetitive but critical. Developers skip tests because writing edge cases is tedious. AI agents can generate tests quickly but often produce brittle, unrealistic tests that provide false confidence. Tests that mock internals, use fake data like "foo@example.com", or test implementation details break on every refactor.

Convert C code to idiomatic C++. Use when migrating C projects to C++, translating C patterns to modern C++ idioms, or refactoring C codebases into C++. Extends meta-convert-dev with C-to-C++ specific patterns covering all 8 pillars (Module, Error, Concurrency, Metaprogramming, Zero/Default, Serialization, Build, Testing).

Use when the user asks to "test", "check", or "verify" something in the app that requires clicking through the UI, not just unit tests.

Use for writing, reviewing, debugging, or testing bounded retry policies in Python with Tenacity, including retry predicates, stop and wait strategies, jitter, exception propagation, callbacks, Retrying, and AsyncRetrying.
