Asset Pipeline Automation
Use when automating the path from generated sprites to a shipped atlas + map so re-generating art does not mean hours of manual rework.

Asset Pipeline Automation
Overview
Manual asset handling does not scale past a few sprites. This skill builds a one-command pipeline: clean -> pack atlas -> emit JSON -> validate, so artists regenerate and the game just updates.
When to Use
- You regenerate assets often and redo packing by hand.
- Atlas/JSON drifts out of sync with the sprites.
- You want a reproducible build step for art.
Process
- Define input (raw generated sprites) and output (atlas + JSON + map) folders.
- Script step 1: background cleanup (see
transparent-cutout-cleanup). - Script step 2: atlas packing + JSON (see
spritesheet-atlas-packing). - Script step 3: validate every referenced sprite exists in the atlas.
- Make it one command (
npm run assets) and idempotent. - Fail loudly if a sprite is missing or an anchor is undefined.
- Run it in CI so broken assets never ship.
npm run assets # clean -> pack -> emit json -> validateRationalizations (Stop Lying to Yourself)
| Excuse | Reality | |---|---| | "Packing by hand is fine for now" | It will not be fine at 100 sprites. Automate early. | | "I will validate manually" | Manual validation misses one sprite and ships a hole. Automate the check. |
Red Flags - STOP if you catch yourself:
- Manual atlas packing on every art change.
- Atlas and JSON drifting out of sync.
- No validation that referenced sprites exist.
Verification
You are NOT done until every box is checked:
- [ ] One command rebuilds atlas + JSON from raw sprites.
- [ ] Pipeline validates all references and fails loudly.
- [ ] Build is idempotent and runs in CI.
