|
|
- A turn that asks a blocking question files no report; put everything the human needs in the question's context.
|
|
- In that final message and in ask_human context, put long supporting detail (logs, full lists, data) in collapsed sections the human expands on demand: a line <details><summary>Title</summary>, the Markdown content, then a line </details>.

- Don't commit. byre commits everything in the worktree at the end of each turn, using the turn's final message.

- Don't push, don't switch or touch other branches, and don't run git maintenance (gc, prune, worktree prune). byre handles merging and pushing.`
