What is shadergraph-build?

A Unity tool that turns a Mermaid diagram—a text drawing of connected steps—into a Shader Graph file, then checks it in the Unity Editor. When the original HLSL shader is available, it also compares the two rendered images pixel by pixel.

Use it to rebuild a Unity shader from a teardown diagram, verify its nodes and connections, inspect compiler messages, and compare its rendered output with the original.

It removes the need to manually recreate shader nodes, ports, and settings, and helps catch graphs that fail to import, compile, or match the original shader.

Token cost

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	$0.00102	$0.01914
Opus 5.5	$0.00041	$0.00766
Sonnet 5.5	$0.00020	$0.00383
Haiku 4.5	$0.00010	$0.00191

Security

Grade A, and why

shadergraph-build 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/mermaid2sg.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Shader Graph build — Mermaid → .shadergraph → verified

Turns the Mermaid produced by shader-teardown into a .shadergraph for the project's exact Shader Graph version, and proves it works. Nothing is hand-typed from memory: node classes, slot IDs, port names, defaults and setting values all come from the running Editor.

Scripts are in scripts/:

Script	Runs in	Does
`SgCatalog.cs`	Editor (`eval_file`)	Dumps every Shader Graph node of the installed version to `Temp/sg_catalog.json`: class, slots (id, name, direction, serialized JSON) and, for every UI setting, the node JSON each value produces
`mermaid2sg.py`	Python	Converts the teardown's Mermaid diagrams into one `.shadergraph`. Fails loudly on any node, port or setting it can't map
`GraphCheck.cs`	Editor (`eval_file`)	Imports the graph, reports compile messages, loads it through Shader Graph's importer and counts nodes / edges / nodes with errors, writes the generated HLSL to `Temp/`
`CompareShaders.cs`	Editor (`eval_file`)	Renders the original shader and the graph on the same sphere under 5 light directions, reports pixel differences, saves an original / graph / diff sheet

Before you start

Ask before writing into the project. Put everything in one new folder (e.g. Assets/_ShaderGraphBuild/). If the project isn't under version control, say so, and offer git init with a Unity .gitignore plus a baseline commit, so the work can be reverted.
Pipeline connection, CLI syntax and safety rules come from unity-pipeline-commands. With pipeline 0.9.x and CLI 1.0.0-beta.2, grouped command names must be quoted: unity command "console get", unity command "editor set_auto_tick" --enable true.
Turn on auto-tick first, so the Editor keeps working while it's in the background.
The CLI waits only about 30 s. Every Editor script here also writes its result to a Temp/sgbuild_*_result.txt file. If the CLI times out (first renders compile shader variants), wait for that file instead of re-running.

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.
