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 | $0.00184 | $0.05811 |
| Opus 5 | $0.00092 | $0.02906 |
| Sonnet 5 | $0.00037 | $0.01162 |
| Haiku 4.5 | $0.00018 | $0.00581 |
Grade A, and why
inventor-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 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.
How it starts
The opening of the file, as written. The whole thing — 456 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Autodesk Inventor 2026 — Parametric Modeling via MCP
When this skill applies
Any task involving the inventor-mcp server: mcp__inventor__connect, create_part, extrude, revolve, hole, chamfer, fillet, circular_pattern, etc. Also any direct Python work against src/inventor_api.py in the inventor-mcp project root\.
Keep explanations concrete; the result that matters is the model in Inventor, not the code.
Token-efficient workflow (USE THESE FIRST)
The MCP server has power tools that replace ad-hoc console scripts:
execute_python(code)— runs Python against liveinv/app/doc/comp/body/tgobjects with a persistent namespace and auto-connect. Use this instead ofpython -c "..."console scripts with 10 lines of import boilerplate.reload_api()— hot-reloadsinventor_api.pyafter editing it. No Claude Code restart needed (new TOOL schemas still need a restart; new wrapper METHODS don't — call them viaexecute_python).inspect()— one-call part snapshot (features, volume, bbox, sketches).list_edges(min_length=...)/list_faces(min_area=...)— compact topology tables; no more hand-written vertex-iteration loops.transaction("begin"/"commit"/"abort")— wrap risky multi-step builds; abort rolls back everything in one call (no manual feature deletion).
Feature tools (extrude, hole, flange, ...) return an auto-report suffix like
| V 23497 (-503 mm³) | F7 E14 — separate volume-check calls are unnecessary.
Core mental model
| Notes | |
|---|---|
| Units | API takes millimeters; Inventor stores internally in cm (the wrapper handles ÷10 automatically) |
| Coordinates | XY is the default sketch plane. Z = "up"/axial in most templates |
| Workflow | connect → create_part → create_sketch → draw_* → extrude/revolve → hole → fillet/chamfer → save |
| Feature indices | 1-based, in creation order (list_features() to see them) |
| Edge indices | 1-based, in Inventor's internal order — change after every feature that adds/removes edges |
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.

inventor-modeling is a skill published in the GitHub repository NeonGlay/inventor-mcp (23 stars, last pushed 3mo ago), licensed MIT. It adds 184 tokens to every session and 5,811 once invoked, about $0.0009 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.
