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 | $0.00025 | $0.00356 |
| Opus 5 | $0.00013 | $0.00178 |
| Sonnet 5 | $0.00005 | $0.00071 |
| Haiku 4.5 | $0.00003 | $0.00036 |
Grade A, and why
openscad-project-understanding 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.
What it actually says
OpenSCAD Project Understanding
Note: This content was generated with the assistance of AI.
Overview
Guidelines for organizing OpenSCAD projects for long-term maintainability, focusing on modularity and clear parameter management.
Project Structure (Recommended)
Follow this file organization for complex models:
- main.scad: Primary assembly file (contains
includeandusecalls). - params.scad: Global parameters and design constants.
- modules/: Directory for individual component modules.
- libraries/: Directory for external libraries (BOSL2, BIT) if not in standard library paths.
Modularity: include vs use
include <file.scad>: Imports all variables, constants, and executes top-level code. Use for parameters and global constants.use <file.scad>: Imports modules and functions without executing top-level code or importing variables. Use for component files.
Library Integration
- BOSL2: Always check for
include <BOSL2/std.scad>at the top of the project. - BIT: Use
include <BoardgameInsertToolkit/BoardgameInsertToolkit.scad>.
Best Practices
- Parametric First: Never hardcode dimensions; use variables defined in a central location.
- Naming Conventions: Use
SNAKE_CASEfor global constants andcamelCasefor local variables. - Documentation: Every module should have a comment describing its purpose and arguments.
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.

openscad-project-understanding is a skill published in the GitHub repository joaorura/openscad-skills (5 stars, last pushed 4mo ago), licensed MIT. It adds 25 tokens to every session and 356 once invoked, about $0.0001 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.
