WHAT IT DOES

What hippo_skill_edit does on Verimem

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

RISK

Why hippo_skill_edit is rated Medium

This tool modifies skill records in the bi-temporal memory engine. Edits are reversible (not destructive) and do not execute external code or move money. The blast radius is medium because incorrect skill edits could degrade AI agent decision-making or cause the agent to apply wrong procedures, but the effect is localized to the memory record and not irreversible.

From the tool's definition Tool name 'hippo_skill_edit' and description 'Edit a skill' indicate modification of stored skill data. The 'edit' operation creates or modifies data reversibly within the memory system.
