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 | $0.00039 | $0.01654 |
| Opus 5.5 | $0.00016 | $0.00662 |
| Sonnet 5.5 | $0.00008 | $0.00331 |
| Haiku 4.5 | $0.00004 | $0.00165 |
Grade A, and why
roblox-npcs 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

- Engine classes:
PathfindingService,Path,PathWaypoint,PathfindingModifier,PathfindingLink,Humanoid
Use PathfindingService for navigation on Roblox's navigation mesh. Build patrol, chase, and other behavior around its computed paths.
PathfindingService basics
Create a path:
local PathfindingService = game:GetService("PathfindingService")
local path = PathfindingService:CreatePath({
AgentRadius = 2,
AgentHeight = 5,
AgentCanJump = true,
AgentCanClimb = false,
WaypointSpacing = 4,
Costs = {
Water = 20,
DangerZone = math.huge,
}
})
path.CalculationSecondsTimeout = 1
Compute and follow:
local humanoid = character:WaitForChild("Humanoid")
local rootPart = character:WaitForChild("HumanoidRootPart")
local success, err = pcall(function()
path:ComputeAsync(rootPart.Position, endPos)
end)
if success and path.Status == Enum.PathStatus.Success then
local waypoints = path:GetWaypoints()
-- follow waypoints with Humanoid:Move()
end
Agent parameters
| Parameter | Default | Purpose |
|---|---|---|
AgentRadius |
2 studs | Minimum clearance from obstacles |
AgentHeight |
5 studs | Vertical clearance |
AgentCanJump |
true | Allows jump waypoints |
AgentCanClimb |
false | Allows climbing truss parts |
WaypointSpacing |
4 studs | Distance between intermediate waypoints |
Costs |
nil | Material/region/link traversal cost |
Path.CalculationSecondsTimeout limits how long the solver may run per ComputeAsync call. Set it after CreatePath and before computing.
PathWaypoint actions
Each waypoint has a Position and an Action:
Enum.PathWaypointAction.Walk: normal movement.Enum.PathWaypointAction.Jump: trigger jump.- Custom labels like
"Climb"or"UseBoat"from PathfindingModifiers/Links.
What ships with it
7 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.

roblox-npcs is a skill published in the GitHub repository nonlooped/roblox-suite (23 stars, last pushed 3d ago), licensed MIT. It adds 39 tokens to every session and 1,654 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 2026-08-30.
