What delimit_github_scan does on Delimit
AI agents call delimit_github_scan to retrieve information from Delimit without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why delimit_github_scan is rated Low
Although the description is empty (lowering confidence), the tool name strongly suggests a scanning/querying operation that retrieves GitHub data for analysis. This aligns with Read category behavior. Severity is medium rather than low because unauthorized GitHub scans could expose sensitive repository information, secrets, or private code to an AI agent.
From the tool's definition Tool name 'delimit_github_scan' indicates it performs a scan operation on GitHub, which typically retrieves and analyzes data without modifying it.
Attacks that exploit this kind of access
The rule that runs delimit_github_scan safely

delimit_github_scan is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Delimit, apply this rule, and every delimit_github_scan call is checked against it from then on.
