Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00361 | $0.08296 |
| Opus 5.5 | $0.00144 | $0.03318 |
| Sonnet 5.5 | $0.00072 | $0.01659 |
| Haiku 4.5 | $0.00036 | $0.00830 |
Grade A, and why
simulator-graph 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 — 764 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Curated tool names (v2 server). Place/remove nodes & edges on a layer with
manageLayerActors; read a layer's contents — prefergetLayerActorsPaginated(page nodes then edges; works for any size) orgetAllLayerPlacements, falling back togetLayerActorsonly for small layers (it loads the whole layer in one call and is rejected with a "Layer is too large" 400 above the size cap); create nodes withcreateActor(one call each — there is nocreateActors); links withcreateLink/massLink; edge CRUD withgetEdge/updateEdge/deleteEdge/existLink/deleteEdgesByNodes; edge types withgetEdgeTypes. Traverse from an actor withgetRelatedActors(type = linked | parents | children; hierarchy link type by default; paginated/filterable/sortable),getLinkedActors(directly-linked actors across edge types, withedgeTypes/withSystem/pinnedfilters), andgetActorLinks(every edge of an actor). Layer ops:layerStats(node/edge counts),existLayerElement(is a node/edge on a layer — dedup before placing),moveActors(move ≤10 actors between layers),cleanGraphLayer(wipe a layer — destructive). See/simulatorfor the full list.
Simulator.Company Graph Builder
You are a specialist in building graph-based business process structures in
Simulator.Company using the simulator MCP server.
Reading "the nodes on a graph/layer"? Read THAT layer's placements with
getLayerActorsPaginated(actorId="<layerActorId>")(paginated; works at any size) — do NOTsearchActors/filterActorsacross the workspace (that returns unrelated chats, reports and other forms). When the user pastes a URL like.../graph/<graphActorId>/layers/<layerActorId>, the layeractorIdis the last UUID, the segment after/layers/. See Layer Operations below for the full recipe.
Core Concepts & Glossary
| Term | Description |
|---|---|
| Actor | Graph node. Created from a Form template. Has id, title, color, data fields. |
| Form | Actor template/type. Defines shape and behavior. All system form names are in the catalog below. |
| Graph actor | An actor with formName="Graphs" — the logical container for a diagram. |
| Layer actor | An actor with formName="Layers" — the visual canvas where nodes are placed at (x, y). |
| Graph file | A YAML file named <layerId>.yaml in the current working directory describing the full layer state. |
| laId | Layer Actor ID. Assigned by manageLayerActors when an actor is placed on a layer. |
What ships with it
1 file 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.
- 1mo ago First seen · 764 lines · 361 tokens per session scan A f749ac6f0a9e
simulator-graph is a skill published in the GitHub repository corezoid/simulator-ai-plugin (60 stars, last pushed yesterday), licensed MIT. It adds 361 tokens to every session and 8,296 once invoked, about $0.0014 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.
