  • New parameterized test in TestUseTool.test_runs
  • Fixed config flush for subprocess execution
  • Removed duplicate tests
  • Simplified hooks/check-test-skeleton.py
  • Removed Import Linter skip exception
  • Removed PytestTool and PyprojectFmtTool exception cases
  • Fix failing pyproject-fmt test: re-apply formatting after files_manager flushes
  • Fix failing Ruff test: wrap tool.apply() in files_manager() so config reads work

Resolves #1664

…mmands

Iterate over ALL_TOOLS, add each via use_tool(), then run via raw_cmd().
Tools without raw_cmd() are skipped. Pytest gets a placeholder test file
to avoid exit code 5. Remove redundant TestCodespell.TestAdd.test_runs.

@copilot there are failing tests - please investigate & fix the bug.

Fixed in 3de949e. The root cause is that tool.apply() runs inside use_tool() (inside files_manager()), which formats pyproject.toml on disk. But when files_manager() exits, it flushes its in-memory state (unformatted) to disk, overwriting the formatting. The fix calls tool.apply() again after files_manager() exits, so the final on-disk file is formatted before raw_cmd() runs. For non-formatter tools, apply() is a no-op.

Fixed in 98ab630. The issue was that RuffTool.apply() calls is_formatter_used() which reads pyproject.toml through the file manager, but tool.apply() was outside files_manager(). Wrapped tool.apply() in its own files_manager() context so config reads work, while still being after the first flush so config is on disk.
