Sanitization
- Metrics artifacts use repo-relative paths and sanitized category/check IDs.
- Metrics artifacts omit fake secret values, raw diffs, command logs, environment variables, generated
.agentguard output, and absolute workspace paths.
Limitations
- Initial foundation only; it is not a broad adversarial corpus.
- Scenarios are deterministic local fixtures, not statistical measurements of production agent behavior.
- Detection depends on configured policies and guard settings.
- The pack does not add new guard primitives, secret detectors, syscall interception, or native filesystem watchers.
