Always write Python code that will pass all rules from the violations index. Edit existing Python code until make wps reports nothing. Fix the code, not the config.

Loop

1. make wps — runs flake8 against .flake8, which selects WPS + E999 and nothing else. Lint one file with uv run --project crates/transferred-py --no-sync flake8 <path>.
2. For each violation, edit the code so its cause is gone — the message names the rule and line; make the smallest change that satisfies it. When a rule's intent is unclear, call explain_violation('WPS###') from the wps MCP server, or read its page under the violation index.
3. Re-run step 1. Done when it exits 0.

Guardrails

• Suppress with # noqa: WPS### (the code, never bare # noqa) only when the user asks, or per-file-ignores already covers the line. Otherwise fix the code.
• Don't add exceptions to .flake8 unless the user explicitly approves the edit. When one rule fires across many files and fixing each is wrong, propose a config change and wait.
• Delete a # noqa: WPS### once flake8 --disable-noqa shows its code no longer fires.
• Ruff owns formatting, imports and the pycodestyle/pyflakes overlap. A WPS fix that ruff then reformats is fine; a WPS fix that fights make ruff is the wrong fix.
