Use this skill when writing tests that need to exercise the system as whole. Also known as end to end tests.
Use this skill to perform a code review. This should be done every time a task involving new feature development is completed
Use this skill when writing Elixir context functions that involve multi-step operations, external API calls, or database operations. Covers using `with` statements, proper error handling, and organizing code in Phoenix contexts.
Use this skill when writing tests for code that interacts with external APIs, third-party services, or LLMs. Covers the behaviour/fake module pattern with configurable implementations.
Use this skill at the beginning and end of a coding session in a Sprite VM. At session start, it checks out main and pulls latest. At session end, it ensures tests pass, commits on a branch, and creates a PR. Invoke this skill when the user starts a session, says they're done, wants to wrap up, or asks to create a PR for their work.
Use this skill when working on any new feature. It enforces a strict test-driven development workflow where tests are written before implementation code.

To run all of the tests in the project, use:
mix test
To include tagged test:
mix test --include tag
To run a single test specify a line number:
mix tests test/waylo/customers_test.exs:34
Do not add extra flags or redirect standard error or output when using mix test.
