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 | $0.00035 | $0.00498 |
| Opus 5 | $0.00017 | $0.00249 |
| Sonnet 5 | $0.00007 | $0.00100 |
| Haiku 4.5 | $0.00003 | $0.00050 |
Grade A, and why
spatial-interchange 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 6d 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
Spatial Interchange
Use plan_conversion before a cross-DCC import or export when source and
target coordinate conventions are known. The tool returns a pure conversion
plan; the importing or exporting adapter remains responsible for applying it
to scene data.
Do not infer a convention from a DCC name alone. Query the live scene, import
settings, or file metadata first: Maya up-axis and units are scene settings,
Blender FBX axes are operator settings, and USD stages carry upAxis and
metersPerUnit metadata.
The 3D Transform Visualizer is a useful educational model for signed right/up/forward bases. It is not a file converter or a source of truth for a live scene.
Workflow
- Inspect source file/scene axes and physical units.
- Inspect the target scene/importer settings.
- Call
plan_conversionwith explicit signed axes and meters per unit. - Apply the returned plan in the owning adapter/importer.
- Validate a landmark point, bounds, face orientation, normals, and animation.
Read references/CONVENTIONS.md for official defaults, runtime caveats, and
the rules for positions, directions, transforms, and mesh winding.
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.

spatial-interchange is a skill published in the GitHub repository dcc-mcp/dcc-mcp-core (42 stars, last pushed yesterday), licensed MIT. It adds 35 tokens to every session and 498 once invoked, about $0.0002 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.
