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 | $0.00259 | $0.04075 |
| Opus 5 | $0.00130 | $0.02037 |
| Sonnet 5 | $0.00052 | $0.00815 |
| Haiku 4.5 | $0.00026 | $0.00407 |
Grade A, and why
physical-item-builder 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 10d 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.
How it starts
The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Physical-item builder
A judgment layer for putting D&D 5e gear into Foundry. It turns an item description — a DMG entry, a stat-block "Equipment" line, or "give the boss a flaming greatsword" — into correctly-shaped, art- bearing, edition-correct Foundry items. It adds NO new mechanics; the tools hold the field shapes.
Authoring policy — READ FIRST
Follow the shared project authoring policy: read
_shared/authoring-policy.md (.claude/skills/_shared/authoring-policy.md)
— 2024 by default · compendium-FIRST (copy the real PHB/DMG item with import-item, even for plain gear;
don't author) · never the SRD · custom = copy a base → modify → rename · can't find a 2024 match →
STOP and ASK (never fall back to 2014/SRD, never invent a rarity/price/damage die) · authoring, not
play. The item-specific shaping rules are in "House rules for shaping items" below.
Tools: import-item (copy from a compendium — the default path), search-compendium-items
(faceted discovery by rarity / subtype / magical — the default way to find gear), search-compendium
(broad name lookup) / get-compendium-entry (confirm the entry; you copy by the hit's pack + id),
add-item (author from scratch — homebrew last resort only), update-actor (actor
currency/coins), update-actor-item / manage-activity / manage-effect (modify a copied
base into a custom item), get-actor / get-actor-entity (read back).
Target: actor inventory vs world library
- Pass
actorIdentifierto put the item on an NPC/PC (its inventory). - Omit it (optionally pass
folder) to create a reusable world Item in the sidebar — for a shared treasure library or loot handed out later.
Step 0 — Find it in the compendium (the default path)
Discover the item with search-compendium-items — faceted by documentType
(gear|weapon|armor|consumable), rarity, itemType (subtype: wondrous / potion / ring / wand / …),
magical, and name. It searches the premium books ONLY (never the dnd5e.* SRD, design.md §2.3)
and ranks them first, so you don't reason about pack ids. (For a quick exact-name lookup,
search-compendium by name also works.) Confirm a hit with get-compendium-entry if you need the full
entry, then copy it with import-item (packId = the hit's pack, itemId = its id, plus
actorIdentifier or folder). On-copy you can name-rename, set quantity, equipped, identified,
or nest in a container. Done — it has the right stats and art.
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.

physical-item-builder is a skill published in the GitHub repository Txpple/fvtt-mcp-molten5e (0 stars, last pushed yesterday), licensed MIT. It adds 259 tokens to every session and 4,075 once invoked, about $0.0013 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
Other skills, from other repositories
gameobject-component-destroy
Destroy one or more Components from a target GameObject. Missing (null) components are skipped — they cannot be destroyed. Use 'gameobject-find' and 'gameobject-component-get' to identify the components first.
unity-version-split
Split a C# file into Unity 6.5+ and pre-Unity 6.5 variants. Use when a file needs different implementations for different Unity versions due to API changes (e.g., EntityId vs int, GetEntityId vs GetInstanceID).
godot-signals-groups
Build event-driven, decoupled Godot 4.7 gameplay with signals and node groups: declare and emit custom signals, connect with Callables (incl. bind/one-shot), and broadcast to many nodes via groups and callgroup. Use when wiring node communication in a Godot project, replacing tight references with signals…
unity-addressables
Manage Addressables groups, entries, profiles and content builds (com.unity.addressables, reflection-based).
motion
How an agent turns a character mesh into a usable animated FBX — and how to judge whether the result is shippable.
threejs-exposure-color-grading
Build a measured exposure and grading path in Three.js. Use for a 64x36 encoded luminance meter, asynchronous readback, weighted log-average exposure, asymmetric adaptation, single tone-map ownership, and a generated 32-cube post-tone-map LUT.
