Rules for writing code in dimos. These address recurring issues found in code review.

​
No comment banners

Don’t use decorative section dividers or box comments. 
# BAD
# ═══════════════════════════════════════════════════════════════════
#  1. Basic iteration
# ═══════════════════════════════════════════════════════════════════

# BAD
# -------------------------------------------------------------------
# Section name
# -------------------------------------------------------------------

# GOOD — just use a plain comment if a section heading is needed
# Basic iteration
If a file has enough sections to warrant banners, it should probably be split into separate files instead. For example, instead of one large test_something.py with banner-separated sections, create a something/ directory: 
# BAD
test_something.py  (500 lines with banner-separated sections)

# GOOD
something/
  test_iteration.py
  test_lifecycle.py
  test_queries.py

​
No __init__.py re-exports

Never add imports to __init__.py files. Re-exporting from __init__.py makes imports too wide and slow — importing one symbol pulls in the entire package tree.

# BAD — dimos/memory2/__init__.py
from dimos.memory2.store import Store, SqliteStore
from dimos.memory2.stream import Stream

# GOOD — import directly from the module
from dimos.memory2.store.base import Store
from dimos.memory2.stream import Stream
