Reduce Astra (GPT-6) costs with cheaper OpenCode subagents

We keep Astra as the primary model for understanding the request, architectural decisions, and final review. Cheaper explore and general subagents handle repository discovery and bounded implementation.

Two pieces make this work: agent definitions specify the models and describe when to use them; AGENTS.md tells the primary agent how to delegate effectively. Below are the actual configuration excerpt and delegation section we use.

opencode.jsonc

Keep Astra selected in the primary session. These entries configure the cheaper workers; substitute model IDs available through your providers.

Amazon Music streams different tracks at different rates, many above the default bit rate that pipewire ships with. This is how to fix it.

Firstly, I am running the Windows Amazon Music app via Crossover, a user-friendly version of wine. It works, it's stable. Ubuntu 22.04. Getting the app can annoying. Once you have the download file, keep it. The app automatically updates and amazingly this works in Linux too. here are some tips: https://uk.amazonforum.com/s/question/0D56Q0000CMRC0dSQH/amazon-music-desktop-app-deletedmissing

Reduce CPU use: I get much, much lower CPU by turning on the DXVK Advanced Option in the Crossover Bottle setting, which keeps the PC fans almost silent for me. The app has an option to use Hardware Accelarated Rendering. I doubt this works on Linux, and it makes no difference. The app doesn't do much rendering while playing back, perhaps this is more for browsing.
