+
+## Code Style
+
+- Always use `=` for assignment, never `<-`.
+- 2-space indentation, 120-character line limit.
+- `snake_case` for functions and variables, `CamelCase` for R6 classes.
+- When calling a function from imported package `foo` do not write
+  `foo::bar()` but `bar()`
+- Double quotes for strings, explicit `TRUE`/`FALSE` (never `T`/`F`),
+  explicit `1L` for integers.
+- Use implicit return values for functions.
+- Prefer `result = if (...) ... else ...` over
+  `if (...) { result = ... } else { result = ... }` when the only
+  difference between branches is the assigned value.
+- User-facing API (exported functions, public R6 methods) must have
+  `checkmate` `assert_*()` argument checks. For internal code, match the
+  existing level of defensiveness.
+- Use these mlr3misc utilities when appropriate: `map()`, `map_chr()`,
+  `invoke()`, `calculate_hash()`, `str_collapse()`, `%nin%`, `%??%`.
+- Before implementing something, read similar existing files first to
+  match the established patterns.
+- Always use `#nolint next` to disable linters for the next line instead
+  of `# nolint` on the same line.
+
+## File structure and naming
+
+- Name the file as the most important contained function / class
+- No whitespaces, no special chart in filenames
+- Usually one large function / class, per file, but adding multiple
+  smaller helpers is ok
+
+## Collation order
+
+- Derived classes must declare `#' @include ParentClass.R` in their
+  roxygen header. This controls the `Collate:` field in DESCRIPTION so
+  base classes load before derived classes.
+
+## Core dependencies
+
+- Use `checkmate` for arg-checks
+- Use `data.table` for efficient table structures
+- For OOP-stype use `R6`
+- Use `cli` to format messages, warnings, errors and prints
+
+## Testing
+
+- Tests for `R/{name}.R` go in `tests/testthat/test_{name}.R`.
+- All new code should have an accompanying test.
+- If there are existing tests, place new tests next to similar existing
+  tests.
+- Strive to keep your tests minimal with few comments.
+- The full test suite takes a long time. Only run tests relevant to your
+  changes with `devtools::test(filter = '^{name}')`.
+
+## Documentation
+
+- Every user-facing function should be exported and have roxygen2
+  documentation.
+- Wrap roxygen comments at 120 characters.
+- Write one sentence per line.
+- If a sentence exceeds the limit, break at a comma, “and”, “or”, “but”,
+  or other appropriate point.
+- Internal functions should not have roxygen documentation.
+- Always re-document the package after changing a roxygen2 comment.
+- Don’t hand-edit generated artifacts: `man/`, or `NAMESPACE`.
+- Roxygen templates live in `man-roxygen/`
+- Bibliographic references go in `R/bibentries.R` and are cited with
+  `` `r format_bib("key")` ``.
+
+## `NEWS.md`
+
+- Every user-facing change should be given a bullet in `NEWS.md`. Do not
+  add bullets for small documentation changes or internal refactorings.
+- Each bullet should briefly describe the change to the end user and
+  mention the related issue in parentheses.
+- A bullet can consist of multiple sentences but should not contain any
+  new lines (i.e. DO NOT line wrap).
+- If the change is related to a function, put the name of the function
+  early in the bullet.
+- Order bullets alphabetically by function name. Put all bullets that
+  don’t mention function names at the beginning.
+
+## GitHub
+
+- If you use `gh` to retrieve information about an issue, always use
+  `--comments` to read all the comments.
+
+## Natural Language
+
+- The following applies to all natural language text, so docs,
+  commments, NEWS, etc, but not code
+- Use American english
+- Use the Oxford comma
+- Do not capitalize normal nouns or method names. “Bayesian” is
+  capitalized, “random forest” is not.
+- Use cspell to check against typos, and add needed words to
+  .cspell/project-words.txt if reasonable
+
+## Further agents files
+
+- Read and respect all files in the `.agents` folder
