Thank you for your recognition and feedback.

I quickly updated the third version.

This version is already very stable and I am quite satisfied.

It is highly recommended that everyone upgrade to this version!

(The picture in Appendix 7 is the latest effect) We have received a lot of feedback from friends, among which codex compatibility and unstable picture output are the most common ones.

Therefore, we seriously solved the problem of "how to stably produce sample-level technical drawings".

🔥 These seven latest pictures are all generated by codex ps: Claude has recently become smarter and recommends everyone to use Codex (GPT5.4 high) to produce pictures 👏 Welcome to give it a triple link and give it a 2K star: Specific update content: ✅ Codex is perfectly compatible - no more errors, and thanks to several friends for their PR ✅ Pushed to Install in one sentence: npx skills add yizhiyanhua-ai/fireworks-tech-graph One sentence upgrade: npx skills add yizhiyanhua-ai/firew orks-tech-graph --force ✅ Upgrade 7 styles from "skin-changing" to "generation system with its own layout language".

Instead of just changing the color, the title area, container, arrow semantics, legend, and brand sense are all written into the logic.

✅ Several old problems that most affect the look and feel have been severely eliminated: - Lines passing through the frame - Label pressing - The path is too mechanical - The composition is loose - The style is like a set of templates ✅ More importantly, this time it is not a few pictures that are beautifully retouched by hand.

Instead, these capabilities are abstracted into formal capabilities, basically ensuring that no errors are reported during the svg code output process: - style_overrides - header_prefix / header_text - side_label - window_controls / meta_* - blueprint_title_block If you continue to expand the image in the future, you no longer need to rely on a bunch of hardcode to support it.

This project is finally starting to smell like a "production-grade generator".

🚀 👀 Comment on this version in one sentence: It has evolved from "capable of producing pictures" to "more like a picture production system that a real team will maintain for a long time." #AI #Agent #RAG #OpenSource #Engineering #Visualization #DeveloperTools
