Global State Risk Reviewer

global-state-risk-reviewer

Purpose

Assess risks introduced by shared mutable global state and recommend containment, encapsulation, or elimination strategies.

Trigger this skill when

• You need a focused refactoring analysis or artifact rather than generic commentary.
• Code quality, maintainability, or testability concerns are affecting delivery.
• You need a reusable output another developer or agent can extend safely.

Expected inputs

• code, module, diff, or architecture slice under review
• known pain points or goals
• constraints or risk tolerance
• existing tests or validation signals

Deliverables

• structured findings or risk review
• ranked recommendations or plan
• assumptions and unresolved questions
• recommended next skill

Operating procedure

1. Clarify the target artifact, pain point, and what successful improvement would look like.
2. Separate explicit evidence from assumptions, missing context, or inference.
3. Apply the relevant smell, anti-pattern, dependency, or refactor framing consistently.
4. Produce compact findings that support prioritization, safe change, and validation.
5. Recommend the next most useful refactoring, review, or testability step.

Quality gates

• Do not recommend refactors with no clear payoff, safety story, or validation path.
• Make uncertainty, evidence quality, and likely blast radius explicit.
• Prefer incremental, reversible changes over speculative rewrites.
• Tie recommendations to maintainability, correctness, testability, or delivery risk.

Handoff targets

• hidden-dependency-detector
• dependency-simplifier
• testability-refactor-planner

Output style

• Be explicit about evidence quality and uncertainty.
• Prefer structured findings over narrative filler.
• Tie recommendations to maintenance cost, defect risk, or delivery consequence.
• Use severity, priority, or confidence labels when useful.

Failure modes to avoid

• Do not equate unfamiliar style with a smell or anti-pattern.
• Do not prescribe rewrites when a smaller refactor would solve the problem.
• Do not hide uncertainty about dynamic behavior, framework constraints, or missing context.
• Do not ignore validation steps when suggesting structural changes.
