Leaderboard Deploy agents

Choose variable and parameter names that clearly communicate their purpose and avoid misleading or cryptic naming. Names should be self-documenting and reduce cognitive load for other developers.

Key principles:

• Avoid names that don’t match their actual purpose (e.g., ref_if_deployment_name when it’s really about branch availability)
• Prefer descriptive terms over abbreviations (e.g., “selected” and “ignored” instead of “SEL” and “IGN”)
• When multiple variables have similar purposes, ensure their relationship is clear through naming

Example of improvement:

# Before: Confusing relationship between parameters
def decide_engine_type(requested_engine, engine_flag):
    requested_engine = engine_flag  # Unclear why both exist

# After: Clear purpose and relationship
def decide_engine_type(engine_flag):
    requested_engine = engine_flag  # Or just use engine_flag directly

This reduces confusion during code reviews and makes the codebase more maintainable by ensuring names accurately reflect their semantic meaning.
