How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file

We split this skill into the rules it gives an agent

1 rule. About 0 are common, 1 is distinctive, and 0 are very specific to this project.

≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.

Common
Distinctive
Very specific

Distinctive:
Avoid black Ambient. Technology is deprecated.
line 76

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Roblox Lighting & Atmosphere

When to Load

Load for Roblox lighting, atmosphere, day/night, or post-processing (Bloom, ColorCorrection, DepthOfField).

Quick Reference

Lighting Service

Lighting.ClockTime = 14            -- 0-24 numeric
Lighting.Brightness = 2            -- 0-10, default 2
Lighting.Ambient = Color3.fromRGB(70, 70, 70)        -- shadow fill
Lighting.OutdoorAmbient = Color3.fromRGB(128, 128, 128)
Lighting.GlobalShadows = true
Lighting.ShadowSoftness = 0.2      -- 0=sharp, 1=soft
-- Configure tech/style/quality in Studio; these properties are not script-writable.
-- Verify enum values and device behavior against current Creator Hub docs before setting them.

Atmosphere

local atmo = Instance.new("Atmosphere")
atmo.Density = 0.3    -- 0=clear, 1=opaque (keep <0.5)
atmo.Offset = 0.25    -- 0=ground, 1=sky
atmo.Color = Color3.fromRGB(199, 199, 199)   -- near fog
atmo.Decay = Color3.fromRGB(92, 92, 92)      -- far/horizon
atmo.Glare = 0        -- 0-10
atmo.Haze = 0         -- 0-10
atmo.Parent = Lighting

Post-Processing (all parented to Lighting)

Effect	Key Properties
`BloomEffect`	Intensity (0-1), Size (px), Threshold (>0.7 recommended)
`ColorCorrectionEffect`	Brightness, Contrast, Saturation (-1 to 1), TintColor
`DepthOfFieldEffect`	FarIntensity, FocusDistance, InFocusRadius, NearIntensity
`SunRaysEffect`	Intensity (0-1), Spread (0-1)

Day/Night Cycle

local CYCLE_SPEED = 1  -- minutes per full day
task.spawn(function()
    while true do
        Lighting.ClockTime += (task.wait() / 60) * (24 / CYCLE_SPEED)
        if Lighting.ClockTime >= 24 then Lighting.ClockTime -= 24 end
    end
end)

Local Lights

Light	Use	Key Props
`PointLight`	Lamps, torches	Range, Brightness, Color
`SpotLight`	Flashlights	Range, Angle, Face
`SurfaceLight`	Screens, panels	Range, Angle, Face

Perf: Limit shadow-casting lights to 4-6 visible. Use Shadows=false on most. Neon material = cheap glow.

MCP: Inspect, change minimally, capture, check performance.

Common Pitfalls

Brightness >3 washes out. Density >0.5 = soup. Max 2-3 post effects.
Avoid black Ambient. Technology is deprecated; it and its replacements are Studio-only.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

It worked
Partly
It didn't

What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
