Proposal: optional completion-check recipe before advancing the queue #3

Hi Ary, I maintain Skillgate, which checks a project's definition of done independently of the coding agent.

PlanQueue's prompt queue and human checkpoints look like a useful fit for a small optional completion-check recipe:

1. Run a queued prompt.
2. Run the project's configured completion check when the turn settles.
3. Advance only when it passes; otherwise pause with the failed checks visible.

The default queue behavior would stay as it is. I would start with one documented example and a generic command/exit-code boundary, without making Skillgate a required dependency. Its existing demo shows the check failing, blocking a commit, then passing after the fix.

This is adjacent to #2's command-execution request, but the question here is whether a check should control progression to the next item. I haven't built or verified a PlanQueue integration yet.

Would a small companion recipe fit the project's scope? If so, I'm happy to contribute an example. Also curious which of my tools first caught your interest.
