-# Ruff Repository
-
-This repository contains both Ruff (a Python linter and formatter) and ty (a Python type checker). The crates follow a naming convention: `ruff_*` for Ruff-specific code and `ty_*` for ty-specific code. ty reuses several Ruff crates, including the Python parser (`ruff_python_parser`) and AST definitions (`ruff_python_ast`).
-
-## Running Tests
-
-Run all tests (using `nextest` for faster execution):
-
-```sh
-cargo nextest run
-```
-
-For faster test execution, use the `fast-test` profile which enables optimizations while retaining debug info:
-
-```sh
-cargo nextest run --cargo-profile fast-test
-```
-
-Run tests for a specific crate:
-
-```sh
-cargo nextest run -p ty_python_semantic
-```
-
-Run a specific mdtest (use a substring of the test name):
-
-```sh
-MDTEST_TEST_FILTER="<filter>" cargo nextest run -p ty_python_semantic mdtest
-```
-
-Update snapshots after running tests:
-
-```sh
-cargo insta accept
-```
-
-## Running Clippy
-
-```sh
-cargo clippy --workspace --all-targets --all-features -- -D warnings
-```
-
-## Running Debug Builds
-
-Use debug builds (not `--release`) when developing, as release builds lack debug assertions and have slower compile times.
-
-Run Ruff:
-
-```sh
-cargo run --bin ruff -- check path/to/file.py
-```
-
-Run ty:
-
-```sh
-cargo run --bin ty -- check path/to/file.py
-```
-
-## Pull Requests
-
-When working on ty, PR titles should start with `[ty]` and be tagged with the `ty` GitHub label.
-
-## Development Guidelines
-
-- All changes must be tested. If you're not testing your changes, you're not done.
-- Get your tests to pass. If you didn't run the tests, your code does not work.
-- Follow existing code style. Check neighboring files for patterns.
-- Always run `uvx pre-commit run -a` at the end of a task.
-- Avoid writing significant amounts of new code. This is often a sign that we're missing an existing method or mechanism that could help solve the problem. Look for existing utilities first.
-- Avoid falling back to patterns that require `panic!`, `unreachable!`, or `.unwrap()`. Instead, try to encode those constraints in the type system.

   "explanation": "## What it does\nChecks for unused imports.\n\n## Why is this bad?\nUnused imports add a performance overhead at runtime, and risk creating\nimport cycles. They also increase the cognitive load of reading the code.\n\nIf an import statement is used to check for the availability or existence\nof a module, consider using `importlib.util.find_spec` instead.\n\nIf an import statement is used to re-export a symbol as part of a module's\npublic interface, consider using a \"redundant\" import alias, which\ninstructs Ruff (and other tools) to respect the re-export, and avoid\nmarking it as unused, as in:\n\n```python\nfrom module import member as member\n```\n\nAlternatively, you can use `__all__` to declare a symbol as part of the module's\ninterface, as in:\n\n```python\n# __init__.py\nimport some_module\n\n__all__ = [\"some_module\"]\n```\n\n## Preview\nWhen [preview] is enabled (and certain simplifying assumptions\nare met), we analyze all import statements for a given module\nwhen determining whether an import is used, rather than simply\nthe last of these statements. This can result in both different and\nmore import statements being marked as unused.\n\nFor example, if a module consists of\n\n```python\nimport a\nimport a.b\n```\n\nthen both statements are marked as unused under [preview], whereas\nonly the second is marked as unused under stable behavior.\n\nAs another example, if a module consists of\n\n```python\nimport a.b\nimport a\n\na.b.foo()\n```\n\nthen a diagnostic will only be emitted for the first line under [preview],\nwhereas a diagnostic would only be emitted for the second line under\nstable behavior.\n\nNote that this behavior is somewhat subjective and is designed\nto conform to the developer's intuition rather than Python's actual\nexecution. To wit, the statement `import a.b` automatically executes\n`import a`, so in some sense `import a` is _always_ redundant\nin the presence of `import a.b`.\n\n\n## Fix safety\n\nFixes to remove unused imports are safe, except in `__init__.py` files.\n\nApplying fixes to `__init__.py` files is currently in preview. The fix offered depends on the\ntype of the unused import. Ruff will suggest a safe fix to export first-party imports with\neither a redundant alias or, if already present in the file, an `__all__` entry. If multiple\n`__all__` declarations are present, Ruff will not offer a fix. Ruff will suggest an unsafe fix\nto remove third-party and standard library imports -- the fix is unsafe because the module's\ninterface changes.\n\nSee [this FAQ section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc)\nfor more details on how Ruff\ndetermines whether an import is first or third-party.\n\n## Example\n\n```python\nimport numpy as np  # unused import\n\n\ndef area(radius):\n    return 3.14 * radius**2\n```\n\nUse instead:\n\n```python\ndef area(radius):\n    return 3.14 * radius**2\n```\n\nTo check the availability of a module, use `importlib.util.find_spec`:\n\n```python\nfrom importlib.util import find_spec\n\nif find_spec(\"numpy\") is not None:\n    print(\"numpy is installed\")\nelse:\n    print(\"numpy is not installed\")\n```\n\n## Options\n- `lint.ignore-init-module-imports`\n- `lint.pyflakes.allowed-unused-imports`\n\n## References\n- [Python documentation: `import`](https://docs.python.org/3/reference/simple_stmts.html#the-import-statement)\n- [Python documentation: `importlib.util.find_spec`](https://docs.python.org/3/library/importlib.html#importlib.util.find_spec)\n- [Typing documentation: interface conventions](https://typing.python.org/en/latest/spec/distributing.html#library-interface-public-and-private-symbols)\n\n[preview]: https://docs.astral.sh/ruff/preview/\n",
