rpgmaker-mz-mcp: Skill for Claude Code

.claude/skills/tileset-catalog/SKILL.md

tileset-catalog is a skill for Claude Code from Redseb/rpgmaker-mz-mcp. It costs 140 tokens per session (1,630 once invoked), scanned A, original, MIT.

A way to label the tiles in a custom RPG Maker MZ tileset by looking at the tile images. A tileset is a collection of small images used to paint a game map.

In plain words
What is it for?
Use it to create a catalog of named tiles for unfamiliar image sheets, so map-painting tools can find tiles by their purpose.
Why use it?
Custom tilesets may not have names that the tools understand, making it hard to find the right grass, wall, or floor tile by meaning.

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.

Security

Grade A, and why

tileset-catalog 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 11d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/png.mjs, scripts/slice-tileset.mjs, scripts/tilegeom.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 133 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Tileset catalog bootstrap

Give a custom tileset the same "ask for grass, get a paintable tile id" layer the built-in Overworld catalog provides — but for sheets the server has never seen. RPG Maker's default sheets ship an English .txt name sidecar (that's how the Overworld catalog was built); custom tilesets don't, so their names must come from looking at the tiles. This skill does that safely: it slices, you name, it writes a file a human verifies before it's trusted.

When to use

  • A project uses a tileset whose sheet filenames aren't World_A1/A2/B/C (i.e. not the built-in Overworld catalog), and you need semantic names for painting.
  • Confirm the gap first: get_tile_catalog(tilesetId) / find_tile come back empty or thin for that tileset — its custom sheets are silently omitted.

Do not use it for the Overworld tileset; that catalog already exists and is authoritative (from RPG Maker's own labels).

What you produce

A versioned catalog at <projectPath>/data/tilecatalog/<Sheet>.json, one file per sheet, keyed by the sheet's local index (autotile kind index for A1–A4, flat tile offset for A5/B–E). Passability and terrain-tag are left null on purpose — those are design decisions, not perception; a human sets them later.

Workflow

Scripts live in scripts/ next to this file and need only Node (built-in zlib; no sharp/canvas/pngjs). Let SKILL=.claude/skills/tileset-catalog.

1. Find the sheets to catalog

Read the project's data/Tilesets.json for the target tilesetId; its tilesetNames array holds the 9 sheet filenames [A1,A2,A3,A4,A5,B,C,D,E] (empty string = unused slot). The image files are in <projectPath>/img/tilesets/. Catalog the non-empty sheets that aren't already covered by the built-in catalog.

2. Slice each sheet into a labelled montage

node $SKILL/scripts/slice-tileset.mjs <projectPath>/img/tilesets/<Sheet>.png <workDir>

Writes <workDir>/<Sheet>.samples.png (a montage: one representative sample per autotile kind — its shape-0, fully-surrounded tile — or per non-transparent flat tile, each with its local index printed above it in white on a dark strip) and <Sheet>.samples.json (index → {kind, tileId}). Fully-transparent flat tiles are dropped; autotile kinds that render mostly-transparent (edge-only sets like clouds) still appear so you can see and name them.

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
