Getting it into your agent

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 | $0.00051 | $0.02499 |
| Opus 5 | $0.00026 | $0.01249 |
| Sonnet 5 | $0.00010 | $0.00500 |
| Haiku 4.5 | $0.00005 | $0.00250 |
Grade A, and why
hz-unity-fbx-import 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 8d 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.

Unity FBX Import with Full URLs
This skill ensures that when importing external 3D models (FBX files) into Unity using the Unity MCP Unity_ImportExternalModel tool, full and complete URLs are always provided, preventing import failures due to incomplete paths.
When to use this skill
Use this skill automatically whenever:
- Importing FBX files from external sources
- Adding 3D models to the Unity project
- Loading assets from URLs or file paths
- User mentions: "import model", "add FBX", "load 3D asset", "bring in model"
- Using the
Unity_ImportExternalModeltool from Unity MCP
Core principle
ALWAYS use complete, fully-qualified URLs for FBX files.
Never use relative paths, partial URLs, or assume path completion. The FbxUrl parameter must be a complete URL or absolute file path.
Instructions
Step 1: Identify the FBX source
When a user requests to import a model, determine the source:
-
Remote URL (HTTP/HTTPS):
- Must start with
http://orhttps:// - Must include the full domain and path
- Filename must end with
.fbxor.zip - IMPORTANT: Include ALL query parameters and tokens after the extension
- Query parameters (like
?param=value&other=data) are required for authentication - Example:
https://example.com/models/character.fbx?token=abc123&auth=xyz - Example:
https://cdn.fbcdn.net/path/file.fbx?_nc_gid=xxx&_nc_oc=yyy&oh=zzz
- Must start with
-
Local file (file system):
- Must be an absolute path (not relative)
- Windows:
C:/Users/name/Downloads/model.fbx - Unix/Mac:
/home/user/models/model.fbx - Must end with
.fbxor.zip
-
ZIP archive:
- Can be URL or local path
- Must contain an FBX file inside
- Example:
https://example.com/assets.zip
Step 2: Validate the URL format
Before calling Unity_ImportExternalModel, verify the URL:
CRITICAL: For URLs with query parameters (like ?token=...&auth=...), you MUST include the ENTIRE URL including all parameters. Query parameters often contain authentication tokens required for download.
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.

hz-unity-fbx-import is a skill published in the GitHub repository meta-quest/agentic-tools (190 stars, last pushed 16d ago), licensed Apache-2.0. It adds 51 tokens to every session and 2,499 once invoked, about $0.0003 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 2026-08-30.
