One addition to conductor/code_styleguides/python.md §8
"AI-Agent Specific Conventions":
- **No diagnostic noise in production code (Added
2026-06-09).** `sys.stderr.write(f"[XYZ_DIAG] ...") lines
in src/*.py are technical debt. The right place for
one-time investigation output is tests/artifacts/<test>.diag.log
(a log file) or a standalone /tmp/diag_<name>.py script.
If you must instrument production code, the diag lines
are part of the same atomic commit as the fix.
- **Test files ARE allowed to be diagnostic.** The rule
applies to src/*.py only; tests/test_*.py may use
print(..., file=sys.stderr) freely.
Markdown only. No code modified.
- Add section 10 (Anti-OOP Conventions) to python.md with hard rules,
class justification requirements, and Strangler Fig refactoring pattern
- Create conductor/refactor_oop.md tracker with 4 phases for class elimination
- Add ruff PLR rules (PLR0912, PLR6301, PLR0206) to pyproject.toml for
OOP anti-patterns
Addresses AI agent scope misinterpretation issues by enforcing flat
function-call graphs over deep class hierarchies.
Replaces Google Python Style Guide with project-specific conventions:
1-space indentation, strict type hints on all signatures/vars,
minimal blank lines, 120-char soft limit, AI-agent conventions.
Also marks type hinting task complete in plan.md.
