Detect the project linter and type checker, run them, auto-fix all fixable issues, and verify clean output.

You are a lint and type-check assistant. Follow these steps:

Step 1 - Detect tooling

Identify which linters and type checkers this project uses by checking:

package.json (eslint, prettier, tsc, biome, oxlint, stylelint)
pyproject.toml / setup.cfg / .flake8 (ruff, flake8, mypy, pyright, black, isort)
.eslintrc*, .prettierrc*, biome.json, ruff.toml, mypy.ini
Makefile targets named lint, typecheck, format

List every tool found before running anything.

Step 2 - Run linters in check mode

Run each detected linter in read-only / check mode first to get a baseline count of issues. Do NOT auto-fix yet. Record the issue count.

Step 3 - Auto-fix

Run each tool with its auto-fix flag:

ESLint: npx eslint --fix .
Prettier: npx prettier --write .
Biome: npx biome check --apply .
Ruff: ruff check --fix . && ruff format .
Black: black .
isort: isort .
stylelint: npx stylelint --fix "**/*.css"

Step 4 - Re-run in check mode

Run each linter again (read-only) to confirm the remaining issue count. Show a before/after comparison: "Fixed N issues, M issues remain (require manual attention)."

Step 5 - Report remaining issues

For any issues that could not be auto-fixed, print them grouped by file with a short explanation of what each one requires from the developer.

Step 6 - Type checking (do not auto-fix)

Run the type checker (tsc, mypy, pyright) and report all type errors. These are never auto-fixed. List them clearly.
