//! Prompt construction.
//!
//! These strings are the actual product. The graph only moves bytes around; how
//! well a run goes is decided by what the judges are asked to look at and what
//! they are forbidden to speculate about.
//!
//! Two rules run through all of them:
//!
//! * **No authorship.** Nothing an agent receives names a model or a vendor,
//!   and every prompt that could invite a guess explicitly forbids guessing.
//! * **Checkable claims.** Judges and reviewers are told to verify assertions
//!   against the repository, and to name a trigger for every defect. That is
//!   what makes an unread patch defensible.

        "\
# Asking the owner\n\n\
If a decision is genuinely the owner's - a product choice, a tradeoff with no \
technically correct answer, something that would be expensive to undo - stop \
and ask instead of guessing:\n\n\
```sh\n\
magi ask --summary \"Which storage backend?\" --choice SQLite --choice Redis\n\
```\n\n\
It blocks and prints the owner's answer on stdout. Omit `--choice` for a \
free-text reply.\n\n\
**Never put this in the background.** The process blocked inside `magi ask` \
*is* the conversation with the owner - it is the only thing that will ever \
read their answer. Backgrounding it, or letting your own process exit while \
it is still running, does not free you to keep working and pick the answer \
up later: it throws the answer away. The owner still sees the question, \
still replies, and nothing is left listening. A single call cannot block \
forever, so instead of hanging until something kills it, it stops on its own \
after a while and prints that nothing has happened yet - not a failure, just \
this call's own turn running out. When you see that, call it again, in the \
foreground, exactly as told:\n\n\
```sh\n\
magi ask --wait <question-id>\n\
```\n\n\
Keep calling `--wait` in the foreground - one blocking call after another - \
until an answer or a reply comes back. It resumes the same wait; it does not \
ask anything new and takes no `--summary`. Backgrounding *this* call throws \
the answer away exactly as backgrounding the first one would.\n\n\
You can attach a page you format yourself, which is how the owner actually \
judges: a diff, a table of what changes, a rendered before and after.\n\n\
```sh\n\
magi ask --summary \"...\" --choice A --choice B --panel panel.html --asset shot.png\n\
```\n\n\
The panel is your own HTML and CSS, rendered in a sandbox: **no JavaScript \
runs and nothing may load from the network**. Inline your styles, reference \
attached assets by their bare filename, and use `data:` URIs for anything \
small. A `<script>`, a remote font or an external image is silently blocked, \
so do not spend effort on them.\n\n\
The owner may answer back with a question of their own instead of deciding - \
`magi ask` then exits 0 and prints what they said, because that is not a \
failure, it is the conversation continuing. Read it, and reply on the same \
question with `--thread`:\n\n\
```sh\n\
magi ask --thread <question-id> --summary \"...\" --choice A --choice B\n\
```\n\n\
This appends your reply and waits again; it does not start a new question, so \
say only what is new. Restate `--choice` if the right answers changed because \
of what the owner asked - the previous choices are gone otherwise, not kept. \
Keep replying on the same thread until an answer comes back.\n\n\
Ask sparingly. A question stops the run until a human notices it, and asking \
about something you could have decided yourself is how that channel becomes \
noise the owner learns to ignore.",
