Velog 시리즈의 이름 또는 URL slug를 수정합니다.
AI agents use velog_update_series to create or update resources in Velog — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Velog environment.
This tool modifies existing series data (name and URL slug) but the changes are reversible—metadata can be updated again. It does not delete data (which would be Destructive) nor execute arbitrary code (Execute). The medium severity reflects that an AI agent could alter series organization and URLs affecting user content visibility, but the changes remain undoable.
From the tool's definition Tool name 'velog_update_series' and description 'Velog 시리즈의 이름 또는 URL slug를 수정합니다' (modifies the name or URL slug of a Velog series). The verb '수정합니다' (modify/update) indicates reversible changes to series metadata.

{
"version": "1",
"default": "deny",
"tools": {
"velog_update_series": {
"limits": [
{
"counter": "velog_update_series_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
