fvtt-mcp-molten5e: Skill for Claude Code

.claude/skills/token-cutout/SKILL.md

token-cutout is a skill for Claude Code from Txpple/fvtt-mcp-molten5e. It costs 200 tokens per session (2,584 once invoked), scanned A, original, MIT.

An image-preparation tool that removes a baked-in background from a token or portrait and saves a transparent RGBA PNG. A token is the image representing a character or creature on a virtual tabletop.

In plain words
What is it for?
Use it to cut out token artwork, preserve or remove a cast shadow, upload the result to Foundry, and assign it as an actor's token image.
Why use it?
It makes images with green screens, flat colors, or busy backgrounds usable on a map without a visible rectangular backdrop.

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

token-cutout 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (token_cutout.py), 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 — 157 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Token cutout

A prep helper that turns a background-baked token image (green/blue screen, a flat white or colored plate, or any busy background) into a transparent RGBA PNG ready to drop on the table — and, if asked, wires it into the live world as an actor's token art.

There is no MCP tool for this — the pixel work is a bundled script, token_cutout.py (next to this file). This skill owns the judgment: which method, whether to keep the cast shadow, verifying the edge, and the optional Foundry hand-off. The Foundry steps reuse the normal tools: upload-asset (asset in) and set-actor-art (assign it).

Step 0 — Get the image and confirm the goal

Need a local file path (the script reads from disk, not from an uploaded asset). If the user only gestured at "the token on my Desktop", find it with a glob first — and note the real extension: a .jpg/.jpeg source has no alpha by definition, which is usually the whole reason we're here.

Step 1 — Pick the method

The script's --method auto (default) uses rembg if installed, else chroma. Override when you know better:

  • rembg (AI matte, U^2-Net) — the default and the right call for a character: soft edges, hair wisps, thin details (bowstrings), and especially a cast shadow on the plate. It's also the only option when the background is not a flat solid color (a scene, a gradient, clutter). First use triggers a one-time ~176MB model download (pip install "rembg[cpu]").
  • chroma (offline, instant, deterministic) — best for a clean flat solid-color plate (classic green/blue screen, or a uniform white/colored back). Auto-detects the key color from the four corners. Prefer it when rembg isn't installed, when you want zero downloads, or for a batch where every image shares the same clean plate. Pass --color RRGGBB to force the key color if auto-detect is fooled by a subject that touches a corner.

When unsure for a single hero token, use rembg. For a bulk folder of identically-plated sprites, chroma is faster and more predictable.

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.
