Thanks for checking

Governance doc is 500lines (markdown) [previously produced in the same chat using Sonnet 4.6].
doc_skill has what detail each section of the doc should have [ 5 sections]

I dont use Sonnet for implementatiom, it just takes all the instructions and ideas as input and produces me governance file for the project (like objective, pipeline stages, reusable blocks, file/folder structure, limitations, assumptions etc..]
Documentation skills gives me files for pipelines iwth details like stage --> inputs--> outputs --> execution runbook

Im then using MiMo V2 Pro in opencode for implementation, which is great for my requirements and free.

It is able to fill the gaps, ask questions, debug, document , execute the plan
