The user called out the LLM training data bias: 'small files are
good, large files are bad.' This is wrong for production codebases.
Unreal has 15K+ line files; OS kernels, game engines, compilers all
routinely have 10K+ line files. File size is a non-issue. Cognitive
load is managed via naming, regions, and navigation tools (the
manual-slop MCP) — NOT via file splitting.
Updates:
1. AGENTS.md (master agent guidance):
- Added 'File Size and Naming Convention' section
- Added the hard rule: 'New namespaced src/<thing>.py files may
only be created on the user's explicit request. If you find
yourself about to create one, ASK FIRST.'
- Defaults: helpers and sub-systems go in the parent module
2. conductor/workflow.md (Guiding Principles):
- Removed 'Do NOT perform large file writes directamente' from
principle 7 (it was a delegating rule, but 'large file writes'
carried the propaganda)
- Added principle 8: 'File Naming Convention (HARD RULE)' that
references AGENTS.md
- Re-phrased principle 9 (Research-First) to clarify it's about
navigation efficiency, not file size
3. conductor/code_styleguides/python.md:
- Removed the 'extremely large files that violate the Anti-OOP
rule by necessity' framing
- Added the new rule about new src/<thing>.py files
4. .opencode/agents/tier3-worker.md and .opencode/agents/tier4-qa.md:
- Re-phrased 'Do NOT read full large files' to 'Use skeleton
tools to navigate any file regardless of size. File size is
not a concern; the right tools are.'
- Added the new rule about not creating new src/<thing>.py
files unless user explicitly requests it
5. conductor/tracks/qwen_llama_grok_followup_20260611/plan.md:
- Updated the 'Naming Convention' section to reference the new
'user explicit request' rule
This is docs-only. No code changes. The rule is now codified:
agents must ASK FIRST before creating new top-level src/ files.
Lesson 5 from the 4-day test-hell saga. The chroma cache lives at
tests/artifacts/.slop_cache/chroma_<collection>/, NOT at the per-run
live_gui_workspace_<timestamp>/ subdir. The trailing-slash bug in
Path(active_project_path).parent places the cache one level higher
than expected.
RAG tests must pre-clean the cache to avoid persistent state from
prior batched runs. Documents the cleanup pattern (shutil.rmtree with
ignore_errors=True), the auto-recovery mechanism (_validate_collection_dim),
and 3 anti-patterns (assuming per-run, not cleaning, asserting on
first chunk in batched context).
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.
Eliminates 22 call sites that bypassed the AppController state owner
and read/wrote config.toml directly. AppController is now the single
source of truth for self.config; gui_2.py, commands.py, etc. go
through controller.save_config() / controller.load_config().
Production changes:
- src/models.py: rename load_config -> _load_config_from_disk,
save_config -> _save_config_to_disk (private I/O primitives)
- src/app_controller.py: add public load_config()/save_config() methods
that own the state. Update 3 internal call sites and 3 ConductorEngine
call sites to pass max_workers from self.config
- src/multi_agent_conductor.py: ConductorEngine.__init__ now takes
max_workers as a parameter (caller responsibility, not I/O primitive)
- src/external_editor.py: get_default_launcher() takes config as a
parameter; gui_2.py:1311,4776 pass app.config
- src/gui_2.py: 17 sites of models.save_config(X.config) replaced with
X.save_config() (delegates via __getattr__ to controller)
- src/commands.py: save_all() uses app.save_config()
Test changes (route through controller, not I/O primitive):
- tests/conftest.py: mock_app and app_instance fixtures now patch
AppController.load_config/save_config instead of models I/O primitives
- 18 other test files: patches renamed from models._save_config_to_disk
to AppController.save_config (and same for load_config)
- tests/test_app_controller_mcp.py: use SLOP_CONFIG env var instead of
patching removed CONFIG_PATH module constant
- tests/test_parallel_execution.py: pass max_workers=2 explicitly to
ConductorEngine (caller no longer reads config)
- tests/test_gui_paths.py: add save_config=MagicMock() to MockApp;
assert on controller method, not I/O primitive
- tests/test_models_no_top_level_tomli_w.py: still calls private
_save_config_to_disk directly (the only allowed exception; tests
the lazy-load behavior of the primitive itself)
New files:
- scripts/audit_no_models_config_io.py: enforces the rule (--strict,
--json modes; AST-based docstring detection to avoid false positives)
- conductor/code_styleguides/config_state_owner.md: documents the rule
Verification:
- 67 targeted tests pass
- scripts/audit_no_models_config_io.py --strict returns 0
This is the architectural cleanup that surfaced during the
audit_architectural_cheats_20260607 review. Closes the smoke-gun
CONFIG_PATH module constant (already done in 0c7ebf22) AND the
free-function models.load_config/save_config smell.
[conductor(checkpoint): config-iO-refactor-20260607]
- 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.
