Unset custom passthrough metadata on a ticket. Core ticket fields are protected.
AI agents use storybloq_ticket_meta_unset to create or update resources in Storybloq — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Storybloq environment.
This tool modifies (unsetting) metadata on tickets, which is a reversible write operation. It does not delete tickets themselves (which would be Destructive) but rather removes custom metadata fields. The protection of core fields limits the blast radius.
From the tool's definition Tool description states 'Unset custom passthrough metadata on a ticket' — this modifies ticket metadata by removing fields. The qualifier 'Core ticket fields are protected' indicates this is a controlled modification that cannot delete critical ticket data.

"default": "deny",
"tools": {
"storybloq_ticket_meta_unset": {

"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
