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 | $0.00183 | $0.01517 |
| Opus 5 | $0.00092 | $0.00758 |
| Sonnet 5 | $0.00037 | $0.00303 |
| Haiku 4.5 | $0.00018 | $0.00152 |
Grade A, and why
chat-and-narration 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.
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 — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chat & narration
A judgment layer over the six chat tools. The tools own correctness (visibility mapping, enrichment, deletes, transcript building); this skill maps the user's intent to the right tool + mode + house formatting. It adds NO new mechanics.
The tools: send-chat-message, list-chat-messages, delete-chat-messages, export-chat-log,
post-item-card, request-roll.
Pick the visibility mode from intent
send-chat-message takes visibility (public / gm / blind / self) plus an optional
speakerActor. Map intent:
| The user wants… | mode | notes |
|---|---|---|
| Narration, announcements, read-aloud, handouts | public |
the whole table |
| An NPC to speak | public + speakerActor: "<npc>" |
"public as character" — renders as that NPC |
| A GM-only aside / secret note | gm |
whispered to all GMs |
| A hidden check the GM resolves privately | blind |
whispers GMs + hides content from others; mainly meaningful for rolls — for plain text it behaves like gm |
| A private scratch note to yourself | self |
only the bridge user sees it |
When in doubt between gm and blind for plain text, use gm — blind only differs for dice rolls.
House formatting
Content is HTML. Keep these shapes consistent:
- NPC dialogue —
speakerActor= the NPC, defaultstyle: ic. Put the spoken line incontent; useflavorfor a stage direction if useful. Example:send-chat-message { content: "<p>\"You shall not pass.\"</p>", visibility: "public", speakerActor: "Gandalf" } - Boxed narration / read-aloud —
public, wrap in a consistent block, e.g.<blockquote>…</blockquote>or<section class="read-aloud">…</section>. - Player handout / image — use the first-class
imagesparam; do NOT hand-write<img>or guess URLs. Each image has anembedmode. If the user gives an image but does NOT make the placement clear, ASK which they want before posting (don't silently pick):- Embed in the HTML (
embed: "dataUri") — the image bytes are read and inlined into the message itself as a base64data:URI. Self-contained, nothing left at a path on the server, but it bloats the message in the world DB — keep it for small images. - Upload to WebDAV at a location (
embed: "webdav", the default) — confirm/choose a Data-relative folder (defaultworlds/<world>/assets/chat), upload the file there, and link its public URL. Permanent and reusable. ⚠️ Served PUBLICLY with no auth — nothing sensitive. If the user already signalled which (e.g. "just embed it" / "put it at worlds/.../maps"), skip the ask and do that. Example:send-chat-message { content: "<p>You find a map.</p>", visibility: "public", images: [{ path: "C:/maps/treasure.webp", caption: "The treasure map", embed: "webdav" }] }

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.

chat-and-narration is a skill published in the GitHub repository Txpple/fvtt-mcp-molten5e (0 stars, last pushed 2d ago), licensed MIT. It adds 183 tokens to every session and 1,517 once invoked, about $0.0009 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.
