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 | $0.00110 | $0.00480 |
| Opus 5 | $0.00055 | $0.00240 |
| Sonnet 5 | $0.00022 | $0.00096 |
| Haiku 4.5 | $0.00011 | $0.00048 |
Grade A, and why
get-material-nodes 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 9d 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
Get Material Nodes — 材质节点图查询
从材质属性入口（BaseColor、Roughness、Normal 等 16 个属性）通过 BFS 遍历所有连接的 MaterialExpression 节点。
Tool
get_material_nodes(material_path, [max_depth], [max_nodes])
Parameters
| Parameter | Type | Default | Description |
|---|---|---|---|
material_path |
string | required | Content browser path, e.g. /Game/Materials/M_Example |
max_depth |
int | 20 | BFS max depth (upper limit: 50) |
max_nodes |
int | 200 | Max collected nodes (upper limit: 500) |
Returns
Each node includes:
- class — e.g.
MaterialExpressionVectorParameter - pos — editor graph position
[x, y] - inputs — input connections (source node, output pin name)
- props — key properties (parameter_name, default_value, texture, etc.)
Top-level response includes property_connections mapping material properties to their directly connected nodes.
Safety
- Per-class property reading (no blind
get_editor_property) - Depth + node count dual limits prevent hangs on complex materials
- Returns
truncated: truewhen limits are hit - 74-node sky material benchmarked at < 5ms
Limitations
- Only
Materialassets — notMaterialInstance(useget_material_parameters) - Only connected nodes reachable via BFS — floating nodes are inaccessible through Python API
total_expressionsvscollecteddifference = floating node count
What ships with it
2 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.

get-material-nodes is a skill published in the GitHub repository IvanYangYangXi/artclaw_bridge (35 stars, last pushed 4mo ago), licensed MIT. It adds 110 tokens to every session and 480 once invoked, about $0.0006 per session on Opus 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 2026-09-03.
