Fable Coding Guidance: Want to use Fable to assist w/Code Improvements & Enhancements - ELI5 / Tips or recommended resources?

Claude Pro user. Usage at Zero.

Had been planning on using Fable to modify and improve my old codebase but hadn't gotten around to it. Now with the extension, I'm hoping to use it today & again potentially when weekly usage resets (before July 12th deadline).

BACKGROUND:

I'm a long-time dev, but last several years just as hobbyist, learning Python. VS Code environment. Python code using Pygame-CE library.

Have mostly used Claude for personal research, and some code assistance (1-shot experiments, with some follow-up).

Only experience with Fable, when first released a while back, was blown-away by capability (again, 1-shot tests).

CODE BASE:

Couple of years ago followed some tutorials & customized a "Sprite Stacking" game engine. Spent time making it fairly *generic* so that I could use it for different types of games.

Not extremely large [ unit.py (# lines of code) ]:

main.py (146), cache.py (292), scene.py (183), settings.py (739), stacked_sprite.py (177), entity.py (143), player.py (143), enemy.py (174), bullet.py (152)

CODE CHANGES:

My Priorities are -

1. Review and Improve/Optimize (examples: my sprite caching & some inherited classes & draw/effects)
2. Add/Expand some basic capabilities (example: import maps from a specific library instead of my pre-defined/hard-coded arrays)
3. [Optional] Add enhancements - perhaps let Claude recommend, likely Effects related

Again, I've only used my Claude account from the web-interface, but I'm technically capable and could setup MCP or other Claude Coding add-ons or API calling configs if this would be highly recommended.

I'm not certain whether I should setup a specific environment, only prompt 1 task at a time (example: priority 1, then priority 2 items).

Any recommended Guides or Tips or Best Practices for someone who wants to maximize his use of Fable for some custom code changes, as outlined here?

Happy to answer any questions and really appreciate any guidance/direction as I'd love to optimize the bit of Fable access that I have available at the moment.

Cheers!
