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.

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 | $0.00048 | $0.01578 |
| Opus 5.5 | $0.00019 | $0.00631 |
| Sonnet 5.5 | $0.00010 | $0.00316 |
| Haiku 4.5 | $0.00005 | $0.00158 |
Grade A, and why
threejs-bloom 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 1mo 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bloom
Treat bloom as the broad tail of an imaging point-spread function. Its closest built-in optical input is all scene-linear HDR radiance. Selective contribution is an art-direction branch, not an automatic quality upgrade.
1. Validate the source scene
Capture scene-linear HDR, false-color pre-tone luminance, and the final image with bloom disabled. Repair the source when highlights were clamped or when silhouette, material, or lighting identity disappears without bloom.
This step is complete when the bloom-off scene remains readable and the input is unclamped scene-linear HDR in a declared working basis.
2. Choose the signal
| Contract | Signal | Admission test |
|---|---|---|
| optical glare from emission, direct response, reflection, transmission, sky, and sun | full scene HDR | a luminance threshold and knee meet contributor error limits |
| named surfaces glow differently from equally bright radiance | selective emissive contribution | full-scene threshold cannot meet those limits and the MRT delta fits |
| optical highlights plus deliberate boost | scene HDR plus selective boost | both components are required and the shared attachment is charged once |
| source scene fails without glare or all bloom tiers miss a gate | defer bloom | source is repaired or budget/viewport changes |
Stabilize exposure before comparing branches. Inspect both false-positive and false-negative bloom energy, including bright mirrors and transmissive surfaces.
This step is complete when one source branch is named, its omissions are accepted, and its contribution error and target-device cost meet declared limits.
3. Build one scene pass
Use one HDR scene traversal for both full-scene and selective bloom. Full-scene
bloom reads the scene output. Selective bloom adds an emissive MRT output to
the same pass and gives it BlendMode(MaterialBlending). Supply explicit
contribution RGBA with the material's alpha and matching RGB convention;
blend factors alone do not repair a bare emissive vec3 or double premultiplication.
The reference includes the per-material expression and corrected emitter.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

threejs-bloom is a skill published in the GitHub repository linegel/threejs-complete-set-of-skill (11 stars, last pushed 1mo ago), licensed ISC. It adds 48 tokens to every session and 1,578 once invoked, about $0.0002 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 2026-08-31.
