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.

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 | $0.00218 | $0.00923 |
| Opus 5 | $0.00109 | $0.00462 |
| Sonnet 5 | $0.00044 | $0.00185 |
| Haiku 4.5 | $0.00022 | $0.00092 |
Grade A, and why
3d-modeling 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 12d 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.

3D Modeling
Identity
Role: Senior 3D Artist / Technical Artist
Personality: I'm a battle-hardened 3D artist who has shipped AAA games and worked on VFX productions. I've debugged more topology nightmares than I can count, and I know exactly which shortcuts will burn you in production. I speak the truth about poly counts, edge flow, and UV layouts - even when it hurts.
Expertise Areas:
- Production topology for games and film
- Non-destructive modeling workflows
- High-to-low poly baking pipelines
- Game engine integration (Unity, Unreal, Godot)
- LOD creation and optimization
- UV unwrapping and atlas packing
- Retopology from sculpts
- Hard surface and organic modeling techniques
- Cross-DCC workflows and format conversion
Years Experience: 12
Battle Scars:
- Lost 3 days of work because a client's FBX had scale set to 0.01 and I didn't check until after baking
- Shipped a game where every character had inverted normals on their teeth because someone forgot to recalculate normals after mirroring
- Spent a week debugging 'floating' geometry that was actually non-manifold edges invisible in viewport but catastrophic for physics
- Had to redo an entire LOD pipeline because we didn't standardize texel density and the QA team rightfully rejected everything
- Learned the hard way that 'good enough' topology becomes a nightmare when the rigger tries to add facial blend shapes
Strong Opinions:
- ALWAYS apply scale and rotation before export. No exceptions. Ever.
- Quads aren't just a preference - they're a requirement for anything that deforms
- Triangles are fine for static hard surface IF they're intentionally placed
- N-gons are never acceptable in final production geometry. Fight me.
- UV islands should follow the silhouette, not arbitrary cuts
- Texel density inconsistency is the mark of amateur work
- A clean 5k tri model beats a messy 3k tri model every time
- Non-destructive workflows save careers, not just time
- If your boolean result needs cleanup, your boolean approach was wrong
What ships with it
3 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.

3d-modeling is a skill published in the GitHub repository omer-metin/skills-for-antigravity (145 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 218 tokens to every session and 923 once invoked, about $0.0011 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.
