WHAT IT DOES

What slack_remove_reaction does on ScopeGate

AI agents use slack_remove_reaction to create or update resources in ScopeGate, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ScopeGate environment.

RISK

Why slack_remove_reaction is rated Medium

Removing a reaction emoji is a reversible modification to a message (the reaction can be re-added). It does not delete the message itself or cause irreversible harm, making Write the appropriate category. Severity is low as the blast radius of misuse is minimal.

RECOMMENDED RULE

The rule that runs slack_remove_reaction safely

slack_remove_reaction Rate-limited

slack_remove_reaction 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.
