Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00031 | $0.00438 |
| Opus 5.5 | $0.00012 | $0.00175 |
| Sonnet 5.5 | $0.00006 | $0.00088 |
| Haiku 4.5 | $0.00003 | $0.00044 |
Grade A, and why
bake-lighting 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 24d 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.

What it actually says
Bake static lighting
Lightmaps remove per-frame shadow and lighting cost for static lights on static geometry.
ApplicationregistersLightmapper; manualAppOptionsbootstraps setlightmapper = Lightmapper.- On the light, set
bake = true; once every mesh it lights is lightmapped, setaffectDynamic = false. - On each mesh, set
render.lightmapped = true, or it goes unlit onceaffectDynamicis off. Size it withlightmapSizeMultiplier;castShadowsLightmaplets meshes shadow each other. - Set the mode on
scene.lightmapMode:BAKE_COLORfor flat diffuse, or the defaultBAKE_COLORDIR, which adds direction for normal- or specular-mapped materials. - Bake AO without lights with
scene.ambientBake,ambientBakeNumSamples, andambientBakeOcclusionBrightnessandambientBakeOcclusionContrast. - The Engine bakes once on the first rendered frame. Call
app.lightmapper.bake(null, mode)only for nodes added later or to re-bake.
A second UV set is required
A node bakes only when every mesh instance has SEMANTIC_TEXCOORD1. Otherwise it is skipped, with
only a debug-build log, and stays dynamically lit. Primitives have the set; imported GLBs often do
not. Check, then unwrap or re-export.
On-device or offline
Time bake() on the target device. Move to an offline bake shipped as textures only when it misses
the startup budget or needs detail the runtime lightmapper cannot produce, and state the added
download size.
Dynamic objects moving through baked light need approximated occlusion and a contact shadow, or
they look pasted on. Compare verify-pixels captures in and out of baked shadow.
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.

bake-lighting is a skill published in the GitHub repository playcanvas/create-playcanvas (61 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 438 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
