## Available Tactics

- systematic-perturbation

## Available SOPs

**Import:** web-search, web-research, paper-overview, paper-search, paper-research
**Subagent:** variation-axis-definition, controlled-perturbation, validity-envelope-construction

## Execution Guidance

Define orthogonal variation axes (data size, noise level, distribution type, etc.), systematically perturb along each axis, measure performance degradation, construct multi-dimensional validity envelope.
