How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Tool Safety75
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Render an asset with two overlaid grids — the RMXP 32px grid (red) and the detected content grid (cyan) — and write a preview PNG for multimodal review. If a tile motif fills a 2x2 block of red cells the art is 64px (too big); if red and cyan coincide it is native 32px. Returns the preview path, detected tile size, and an alignment verdict. Read the returned preview_png to confirm visually before registering.
| Name | Type | Req | Description |
|---|---|---|---|
| filePath | string | yes | Absolute path to the tileset PNG |
| outDir | string | – | Output directory for the preview PNG (default %TEMP%/rmxp-verify) |
