What is generate2dmap?

Instructions for generating 2D tile maps and game scenes in Aseprite using grid-based layouts, layers, tile types, and collision data.

Use them to build game environments, place tiles on a grid, organize map layers, define collisions, and export PNG or animated GIF maps.

They turn a game-level idea into an organized map with consistent coordinates, layers, and export settings.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00042	$0.04753
Opus 5.5	$0.00017	$0.01901
Sonnet 5.5	$0.00008	$0.00951
Haiku 4.5	$0.00004	$0.00475

Security

Grade A, and why

generate2dmap scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

generate2dmap

Structured tile map generation using aseprite-mcp drawing tools. Define tile set → plan map grid → build layers → place tiles → export.

Tool reference

Tool	Purpose
`create_sprite`	Start a new sprite (width, height)
`draw_pixels`	Place individual pixels
`draw_line`	Bresenham line
`draw_rectangle`	Filled or outline rectangle
`draw_circle`	Filled or outline circle
`flood_fill`	Fill contiguous area
`add_layer`	New layer for map depth
`remove_layer`	Delete a layer
`add_frame`	New frame for animated tiles
`set_frame_duration`	Set frame timing
`export_png`	Export to PNG
`export_gif`	Export animated map
`get_sprite_info`	Read sprite dimensions
`inspect_sprite`	Full cel dump
`get_pixel_color`	Read pixel color
`resize_canvas`	Change sprite dimensions

Map conventions

Grid and canvas

Tile size: 16×16 (standard) or 32×32 (detailed)
Canvas: tile_size × map_width × map_height pixels
- Example: 16×16 tiles, 20×15 grid → 320×240 canvas
Origin: top-left (0,0)

Coordinate system

Tile (col, row) → pixel (col * tile_w, row * tile_h)

Example for 16×16 tiles:
  Tile (0,0) → pixel (0,0)
  Tile (1,0) → pixel (16,0)
  Tile (5,3) → pixel (80,48)

Tile types

Define tile set before building the map:

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
