A set of live project rules describing the PS3D CAD Studio repository, its technology, connected services, and verification commands. A repository is the project's files and history; these rules give coding agents the context needed to work in it.

It is for guiding changes to the PS3D CAD Studio codebase, choosing the correct build and test commands, and preserving project-specific technical constraints.

It prevents agents from guessing the project's name, structure, tools, or required checks. It also records which repositories and external systems are currently in scope.

Token cost

What it costs to keep this loaded

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	$0.00014	$0.01198
Opus 5.5	$0.00006	$0.00479
Sonnet 5.5	$0.00003	$0.00240
Haiku 4.5	$0.00001	$0.00120

Security

Grade A, and why

project 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 1mo 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.

project is a cursor rule published in the GitHub repository sagar25-Code-it/ps3d-cad-studio (0 stars, last pushed 3d ago), licensed MIT. It adds 14 tokens to every session and 1,198 once invoked, about $0.0001 per session on Opus 5.5. 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.
