RISK

Why sch_add_datafile_link is rated Medium

The tool performs a creation/linking operation ('add') on schematic data. Without explicit description, we infer from the name that it creates or modifies an association between schematic elements and external datafiles. This is Write-category (reversible modification) rather than Execute because it targets data structure modification rather than arbitrary code execution.

From the tool's definition Tool name 'sch_add_datafile_link' indicates adding or linking a datafile to a schematic, which modifies schematic project state. In the context of Altium Designer, adding datafile links is a reversible modification to design artifacts.

sch_add_datafile_link Rate-limited

sch_add_datafile_link 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.
