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 | $0.00202 | $0.02987 |
| Opus 5 | $0.00101 | $0.01494 |
| Sonnet 5 | $0.00040 | $0.00597 |
| Haiku 4.5 | $0.00020 | $0.00299 |
Grade A, and why
inventor-din-parts 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 13d 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 — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.
DIN/ISO Standard Mechanical Parts — Parametric Templates
Prerequisite
Read inventor-modeling skill first if any uncertainty about Inventor MCP setup, units, the "positive extrude" rule, etc. This skill builds on those primitives.
When to use this skill
User wants a specific standard part with a defined designation:
- DIN 934 / ISO 4032 hex nut
- DIN 933 / ISO 4017 hex bolt (full thread)
- DIN 931 / ISO 4014 hex bolt (partial thread)
- DIN 125 / ISO 7089 flat washer
- DIN 127 spring washer
- DIN 2573 / EN 1092 flange
If the user says just "make a part shaped like X", that's the inventor-modeling skill (not this one).
Standard dimension tables
These are the authoritative dimensions. Always use them — don't ask the user "what's the height of M16 nut".
DIN 934 — Hex Nut (ISO 4032)
| Thread | s (across flats) | m (height) | Coarse pitch |
|---|---|---|---|
| M5 | 8 | 4.0 | 0.8 |
| M6 | 10 | 5.0 | 1.0 |
| M8 | 13 | 6.5 | 1.25 |
| M10 | 16 | 8.0 | 1.5 |
| M12 | 18 | 10.0 | 1.75 |

Helper: circumradius = s / √3, apothem = s / 2.
DIN 933 — Hex Bolt (fully threaded), DIN 931 (partially threaded)

DIN 125 — Flat Washer, type A (ISO 7089)

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-din-parts is a skill published in the GitHub repository NeonGlay/inventor-mcp (24 stars, last pushed 3mo ago), licensed MIT. It adds 202 tokens to every session and 2,987 once invoked, about $0.0010 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.
