How It Works

Summer automatically analyzes and indexes your project to understand:
  • Code structure - Classes, functions, variables, and their relationships
  • Scene hierarchy - Node trees, components, and connections
  • Asset relationships - Textures, models, sounds, and where they’re used
  • Project patterns - Your coding style, naming conventions, and architecture

​
Automatic Indexing

When you open a project, Summer:
1

Scans all files

Analyzes scripts, scenes, resources, and project settings
2

Builds knowledge graph

Creates connections between different parts of your project
3

Understands context

Learns your patterns and project-specific logic
4

Stays updated

Continuously updates as you make changes

​
What Summer Knows

​
Code Understanding

# Summer knows this is a player controller
extends CharacterBody3D
class_name Player

@export var speed: float = 5.0
@export var jump_velocity: float = 4.5

func _physics_process(delta):
    # Summer understands this handles movement
    handle_movement(delta)
When you ask “make the player faster”, Summer knows:
  • Which script controls the player
  • That speed is the relevant variable
  • How to modify it safely

​
Scene Relationships

Main Scene
├── Player (CharacterBody3D)
│   ├── MeshInstance3D
│   └── CollisionShape3D
├── Environment
└── UI
    ├── HealthBar
    └── Score
Summer understands these connections and can:
  • Add UI elements that reference the player
  • Create enemies that target the player node
  • Modify scenes while preserving relationships

​
Smart Suggestions

Based on project analysis, Summer can suggest:

Performance Improvements

“I noticed you’re using get_node() in _process. Let me cache those references.”

Best Practices

“This signal connection could be done in the editor instead of code.”

Bug Prevention

“Adding null checks here would prevent crashes when nodes are freed.”

Architecture Patterns

“Consider using a state machine for this enemy behavior.”

​
Privacy & Performance

Local Processing: All analysis happens on your machine. Your code never leaves your computer.
Incremental Updates: Only changed files are re-analyzed, keeping things fast.
Smart Caching: Summer remembers what it learned between sessions.

​
Customizing Intelligence

You can guide Summer’s understanding:

​
Project Comments

# SUMMER: This is the main game manager singleton
extends Node

# SUMMER: Handle player spawning and respawning
func spawn_player():
    pass

​
Ignore Patterns

Create a .summerignore file: 
# Don't analyze generated files
.import/
builds/
temp/

# Skip third-party code
addons/third_party/

​
Working with Large Projects

For projects with thousands of files:
  • Prioritization: Summer focuses on recently modified files
  • Selective indexing: You can specify which folders are most important
  • Background processing: Analysis happens without blocking your work
