Quick brief
Use checksec when an agent needs to verify whether compiled binaries or system executables have common exploit mitigations enabled. A user should invoke this instead of treating the project as a generic security tool when the task is a bounded hardening verification pass on specific artifacts before release, review, or triage. The scope boundary is clear and skill-shaped: binary protection inspection with structured results, not a plain product listing.
