andresnator Activation Contract
Load this skill when reviewing refactor plans for: input validation, preconditions, boundary validation.
Hard Rules
- Validate at system and module boundaries.
- Flag implicit assumptions that can fail at runtime.
- Centralize duplicated validation only when it represents one business rule.
- Do not scatter defensive checks inside pure internals without need.
- Preserve observable behavior; label functional changes as follow-up.
- Require evidence for every recommendation, or mark it as a hypothesis.
Decision Gates
| Signal | Action |
|---|---|
| Concrete evidence exists | Create a finding with file, lines, symbol, benefit, validation, and rollback. |
| Evidence is incomplete | Mark as hypothesis and lower confidence. |
| Recommendation is cosmetic or speculative | Omit it unless maintainability benefit is clear. |
Execution Steps
- Inspect the target and nearby tests only as needed for this lens.
- Identify findings that match this skill's responsibility.
- Recommend the smallest safe behavior-preserving refactor.
- Add validation and rollback steps for each recommendation.
Output Contract
Return structured findings for the calling reviewer. Return no_findings when this lens has no material issue.
