playtest-patterns SKILL.md skillA
playtest-patterns from hermeticormus/claude-code-game-development is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Playtest instrumentation patterns: death heatmap collection, an analytics event schema, a time-per-zone tracker, a session guide template, and A/B test assignment. Use when adding telemetry to a build or preparing a playtest session.
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
# Playtest Patterns
## Death Heatmap Collection
```gdscript
# Collect and visualize death positions as a heatmap overlay
class_name DeathHeatmap extends Node2D
var _death_positions: Dictionary = {} # Vector2i -> int (count)
@export var cell_size: int = 16 # Group deaths by cell size (pixels or world units)
@export var max_heat: int = 10 # Deaths at or above this = max color intensity
@export var heat_color_cold: Color = Color(0, 0, 1, 0.3) # Blue = few deaths
@export var heat_color_hot: Color = Color(1, 0, 0, 0.7) # Red = many deaths
func record_death(world_position: Vector2) -> void:
var cell := Vector2i(int(world_position.x / cell_size), int(world_position.y / cell_size))
_death_positions[cell] = _death_positions.get(cell, 0) + 1
queue_redraw()
_save_to_disk() # Persist across sessions
func _draw() -> void:
for cell in _death_positions:
var count: int = _death_positions[cell]
var heat := clampf(float(count) / float(max_heat), 0.0, 1.0)
var color := heat_color_cold.lerp(heat_color_hot, heat)
var rect := Rect2(
Vector2(cell) * cell_size,
Vector2(cell_size, cell_size)
)

How to install
mdr add hermeticormus/claude-code-game-development/playtest-patterns@sha256:81016cbab401f090The 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.
