WHAT IT DOES

What lib_create_passive_symbol does on Eda Agent

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

RISK

Why lib_create_passive_symbol is rated Medium

Creating symbols is a reversible write operation that modifies library data. While this affects design artifacts, it does not delete data (so not Destructive), execute arbitrary code (so not Execute), or cause financial impact. The medium severity reflects that symbol library corruption could impact downstream designs, but the effect is localized to a design asset and reversible through undo or re-creation.

From the tool's definition Tool name contains 'create' and is in 'lib_' (library) namespace, indicating creation of a passive symbol object in Altium Designer's component library. Description is empty.

lib_create_passive_symbol Rate-limited

lib_create_passive_symbol 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.
