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 | $0.00052 | $0.00558 |
| Opus 5 | $0.00026 | $0.00279 |
| Sonnet 5 | $0.00010 | $0.00112 |
| Haiku 4.5 | $0.00005 | $0.00056 |
Grade A, and why
designer-session 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 10d 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
Designer Session
Read the active Designer session and graph before mutating it. The public tools
create only bounded built-in sbs:: node types, address explicit node and
property identifiers, and accept an allowlisted set of scalar and vector value
types. They do not expose an eval, script, shell, or generic action surface.
Use export_graph_state after each authoring sequence to verify node count,
type URLs, positions, parameters, topology, and output usages. A typical graph
sequence is create_graph → create_node → connect_nodes →
set_parameter/expose_parameter → add_output/set_output_usage →
save_package_as → export_graph_state.
Package tools use Designer's package manager. Bitmap and SVG imports validate
the declared resource kind and use linked resources unless embed=true is
explicitly requested. export_sbsar uses Designer's official SBSAR exporter
and verifies that the requested artifact exists. export_maps invokes only the
official sbsrender executable discovered by the host environment and always
requires explicit format, bit depth, and color-space settings; it fails closed
when that executable is unavailable.
Parameter exposure is capability-gated. If the running Designer build does not
provide the supported binding API, the tool returns EXPOSE_API_UNAVAILABLE
instead of creating an unbound graph property. Host API calls remain on the
Designer main thread through the adapter's Core execution bridge.
The higher-level procedural and imported-PBR tools remain available for common material recipes. Use the granular tools when the graph topology or package lifecycle must be controlled and verified step by step.

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.

designer-session is a skill published in the GitHub repository dcc-mcp/dcc-mcp-substance3d-designer (0 stars, last pushed 16d ago), licensed MIT. It adds 52 tokens to every session and 558 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 2026-08-31.
