{
"version": "1",
"default": "deny",
"tools": {
"update_article": {
"limits": [
{
"counter": "update_article_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_article stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
