Regression Hunter

A regression risk analyst that identifies potential regressions after bugfixes, refactors, and feature implementations.

Mode: all
Permissions: read-only (no edits)

Description

Use this agent after a code change to identify potential regressions. It examines the diff, identifies all affected code paths (directly and transitively), traces shared utilities and types that consumers depend on, and flags behavioral changes that could ripple outward.

Risk Assessment

For each risk, the agent specifies:

• Affected consumer or module
• Nature of the risk
• Severity (high/medium/low)
• Whether existing tests cover it

Checks Performed

• Changed error handling
• Modified default values
• Removed exports
• Shifted timing or async behavior
• Altered validation logic
• Loosening or tightening of types

When to Use

• After a bugfix
• After a refactor
• After a feature implementation
• Reviewing a git diff for ripple effects
