When working in 'propose mode' and running out of context, the skill is not loaded correctly upon resuming. There should be a way to resume working on a PR or skill from a specific point, even if artifacts are marked 'done' from a previous session.
I was working in propose mode and ran out of context window so prompted for the prompt to start with in a new session. I got a prompt to read the current changes files, but the skill was not loaded. When I manually loaded the skill into the session and asked it to resume at item 3 (Get the artifact build order), it did that, but it then didn't run the `openspec instructions` command because each artifact's state was `done` and not `ready`. There should be some way to resume the working on a proposed change.
