Save system code patterns: a core save manager, a save data model, slot metadata for load screens, and settings persistence kept separate from game saves. Use when implementing saving and loading in a game.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Save System Patterns
## Core Save Manager
```gdscript
# Save system with versioning, atomic writes, and migration
class_name SaveManager extends Node
const SAVE_DIR := "user://"
const SAVE_VERSION := 2 # Increment when save schema changes
func save_game(slot: int, data: Dictionary) -> Error:
var path := _get_save_path(slot)
var tmp_path := path + ".tmp"
# Add metadata
data["version"] = SAVE_VERSION
data["timestamp"] = Time.get_unix_time_from_system()
var file := FileAccess.open(tmp_path, FileAccess.WRITE)
if not file:
return FileAccess.get_open_error()
file.store_string(JSON.stringify(data, "\t"))
file.close()
# Backup existing save before replacing
if FileAccess.file_exists(path):
DirAccess.copy_absolute(path, path + ".bak")
# Atomic rename: if crash happens before this, .tmp exists but save is intact
var dir := DirAccess.open(SAVE_DIR)
return dir.rename(tmp_path.get_file(), path.get_file())
func load_game(slot: int) -> Dictionary:
var path := _get_save_path(slot)
if not FileAccess.file_exists(path):
return {}
var file := FileAccess.open(path, FileAccess.READ)

How to install
mdr add hermeticormus/claude-code-game-development/save-system-patterns@sha256:f555b49c82657f96The line at the top of this page pins the label git:20260930.4aecd99, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
