What is rpg-scene-forge?

A tool that turns tactical locations from campaign notes into Foundry Virtual Tabletop scenes with lighting suited to the place. It links an existing scene when possible and asks before generating a new battle map.

Use it to find or create encounter scenes, set darkness and visibility, place the scene in the campaign build, and record which scene was used.

It removes repetitive scene setup while protecting existing maps and avoiding unwanted image-generation jobs. It keeps story-only locations separate from places where encounters happen.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00152	$0.00795
Opus 5.5	$0.00061	$0.00318
Sonnet 5.5	$0.00030	$0.00159
Haiku 4.5	$0.00015	$0.00080

Security

Grade A, and why

rpg-scene-forge 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 2mo 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.

The opening of the file, as written. The whole thing — 24 lines — stays where its author put it; the contents beside it link to each section on GitHub.

RPG Scene Forge — locations → Foundry scenes + lighting

What this skill is for

Turn each tactical local — one that is an encontro.location (the resolver lists these as tacticalLocals) — into a Foundry scene that's lit for play. You do not author the place — its description is the vault note's body. You realize it: find or make the scene, light it, record the id. Narrative locals (no encounter — narrativeLocals) are NOT your job: rpg-journal-forge turns them into image handouts; only link a pre-existing gridless backdrop if the user made one (see references/scene-policy.md). Never generate-map a narrative local.

Workflow

Prefer existing. list-scenes and match by the local's name (and aliases). If a scene matches, link it (record source: linked) — do not regenerate.
Generate only if missing, with confirmation. generate-map is async and uses local ComfyUI (slow, a real compute job). Ask before spending one. Build the prompt from the local's body + the campaign tone (judgment — see references/scene-policy.md). Call generate-map(prompt, scene_name, size, grid_size), record the jobId in the manifest, then poll check-map-status(jobId) until complete. The module sets the background automatically (patched for v14).
Light it. Pick a mood (bright/dim/dark/pitch) from tone + place kind; foundry-args.suggestMood gives a default, lightingForMood gives the numbers; apply with set-scene-lighting(darkness, globalLight, tokenVision). See references/lighting-and-geometry.md.
Walls = human's job. Do NOT auto-trace walls on painted/organic maps (they float and look wrong — hard-won verdict). Only create-walls for simple, known, grid-aligned geometry the user explicitly asks for. Record walls: skipped.
Serialize. All writes to ONE scene happen as a single sequential batch — never parallel (the 2nd write silently no-ops).
Return { sceneId, source, lit } to the conductor for the manifest. (Binding a soundtrack to this scene's Ambience is a downstream step owned by rpg-soundscape-forge, which consumes this sceneId — not your job here.)

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.
