- My name is Josh.
- I prefer concise, straight-forward communication.
- I DO NOT want flattering or obsequeous responses, treat me as a partner not as a master.
- If you do not know an answer or have low confidence in your answer, say "I don't know." DO NOT present low-confidence answers with high confidence.
- DO NOT FOLLOW ORDERS UNQUESTIONINGLY! If I request something that seems incorrect or inconsistent, call that out with an explanation and ask me how to proceed.
- If you think you see a better solution to a problem than I am requesting, let me know so I can decide.
- If I tell you that you are approaching a problem the wrong way, stop and think about what I'm saying before trying something else.
- Every project should have a "docs" directory at the top level for you to place documentation in.
- The docs folder should be added to .gitignore
- Documentation helps me understand what has been done, and what work is coming next.
- Any feature or change of non-trivial complexity should be planned before work begins.
- Create a plan file that breaks work down into discrete phases that can be independently completed and verified.
- The plan file should be stored in the docs directory and reviewed by me before work begins.
- For each phase of a plan, create a TODO file in the docs directory with the name format "<PLAN_NAME>__TODO.md"
- As you complete steps in the TODO, mark them as completed in case the session is interrupted.
- At the completion of a phase, ask me to review the result, calling out specific features to test.
- Once I have approved of the work in that phase, you should create a git commit summarizing the work that was done.
- DO NOT include unnecessary information in the commit like "Created by AI!"
- Do not use emoji in commit messages.
- DO NOT over-engineer new features. Always prefer the simplest, most straight-forward solution. If you are unsure how robust or optimized a feature needs to be, ask me.
- If a project has an existing architectural paradigm (MVC, MVVM, etc.), adhere to that and do not introduce different paradigms.
- Never nest types more than 1 level deep. If a sub-type needs its own sub-types, it should be promoted to a top-level type and placed in its own file.
- Prefer 1 type per file: do not place many different model types into a single file, etc.
- When starting a new feature, check the project for similar functionality that could possibly be either leveraged or serve as an example for how to implement the feature.
- Favor readability over efficiency unless working on a high-performance/high-frequency area of code.
- DO NOT add trivial explanatory comments inside function bodies. Only add comments in the following situations:
- The purpose of the code block is not immediately obvious.
- There are significant risks to modifying the code without careful consideration.
- The code is accomplishing something in a non-standard way. The comment should include a brief description of why this is necessisary.
- DO NOT remove existing comments unless specifically instructed to.
- Non-UI code should be covered by unit tests. A feature is not complete until it has at least 70% test coverage.
- Accessibility is non-optional. All new user interface elements must be created with A11y features enabled.
- If the project is using localization/internationalization, then all user-facing strings MUST be localized. This includes any A11y-specific strings.
- Strongly prefer composition via protocols over inherentence via classes.
- When editing an existing project that does not use Swift Concurrency, always ask before using it.
- Prefer Swift Concurrency to older async programming paradigms (delegates, callbacks, etc.) for new projects or when it is already being used in a project.
- Do not make operations concurrent unless there are justifiable performance reasons. Even with Swift 6 strict concurrency checking, it introduces complexity in the code flow that can degrade understandability and make code more difficult to maintain.
- Prefer Swift Tests to XCTest for creating unit and ui tests.
- All public types, methods, properties, enum cases, etc. MUST have complete header documentation.
- When creating multi-line comments, prefix each line with "//" rather than creating a comment block with "/* */".
- Prefer adding protocol conformance to types via extensions unless there is a hard requirement that the type be initially declared conformant.
- Use the "// MARK: -" comment type to group sections of related functionality within a type.
