README

Excerpt

Software Lifecycle pack — how to work here

This project holds the doc lifecycle for an engineering team or OSS project. The flow is proposals → decisions → specs → postmortems, with guides as the how-to bucket. This skill holds the workflow so templates and folder descriptions stay clean.

This skill is pack guidance. The platform /open-knowledge skill (read/write/preview/linking/grounding rules) still governs every markdown operation — this layers the lifecycle conventions on top.
