# spawn-unplaced

An advisory by default: it explains, and blocks nothing, on a subagent's first call that no waiting spawn names, which then runs under no lease.

## What it catches

A subagent's first call that no waiting spawn names, which then runs under no lease.

## Why

Advice, not a refusal: the caller may be no worker at all, and spawns wait for their child up to two minutes.

## Default and override

By default this rule takes the decision `advise`. A workspace sets it by name, in its root
magusfile, to `advise` or `off`:

```buzz
magus\guard.builtins({"spawn-unplaced": "off"})
```

A loosening takes effect once it is committed; a tightening applies at once.

## Seeing it

A verdict names its rule in brackets, which is how you got here:

```text
advise [spawn-unplaced]: ...
```

`magus describe rule spawn-unplaced` prints the same entry at a terminal, and
`magus describe rules` lists every rule this workspace enforces.
