assets-create-folder

assets-create-folder is a skill for Claude Code, Codex from IvanMurzak/Unity-MCP. It costs 55 tokens per session (924 once invoked), scanned A, original, Apache-2.0.

A tool for creating folders inside Unity’s Assets folder. The parent folders must already exist, and the new folder name must use valid characters.

In plain words
What is it for?
Use it to create one or more asset folders, organize scripts and resources, and receive the identifiers of folders created successfully.
Why use it?
It makes project organization repeatable and reports errors for missing parents, duplicate folders, or invalid names.

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.

Security

Grade A, and why

assets-create-folder 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 4d 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 — 128 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Assets / Create Folder

Creates a new folder in the specified parent folder. The parent folder string must start with the 'Assets' folder, and all folders within the parent folder string must already exist. For example, when specifying 'Assets/ParentFolder1/ParentFolder2/', the new folder will be created in 'ParentFolder2' only if ParentFolder1 and ParentFolder2 already exist. Use it to organize scripts and assets in the project. Does AssetDatabase.Refresh() at the end. Returns the GUID of the newly created folder, if successful.

Inputs

  • inputs — list of {ParentFolderPath, NewFolderName} entries. Each entry is processed independently; per-entry errors are collected in the response so a single bad input does not abort the batch.

Validation

  • NewFolderName must be non-empty and must not contain any of /, \, <, >, :, ", |, ?, *, or control characters (these checks are cross-platform even on Linux/Mac).
  • ParentFolderPath must already exist as an AssetDatabase.IsValidFolder path.
  • A folder with the same target name must not already exist under the parent.

How to Call

unity-mcp-cli run-tool assets-create-folder --input '{
  "inputs": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool assets-create-folder --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool assets-create-folder --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

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.
