Default severityHIGHEvidence classcapability
What it means

Read the evidence before the label.

This alert records capability evidence produced by the AST analyzer. Its default severity describes potential impact, not certainty that an extension is malicious.

A final decision also considers evidence correlation, artifact identity, analysis coverage, and the active policy.

Expected evidence

Exact extension version, artifact hash, affected file or dependency, normalized rule identifier, confidence, and scanner ruleset.

Reviewer action

Confirm whether the behavior matches the extension’s declared purpose and whether execution requires explicit user intent.
