detect-quality-regressions

Purpose

Compare current quality metrics against a stored baseline to detect regressions in tests, coverage, type errors, linting, and dead code. Enforces quality standards by blocking task completion when metrics degrade beyond tolerance thresholds.

When to Use

MANDATORY invocation scenarios:

• After completing a task (before marking complete)
• Before creating a commit or pull request
• Before merging to main branch
• When user asks "is this done?" or "check quality"

User trigger phrases:

• "detect regressions"
• "check against baseline"
• "validate quality hasn't degraded"
• "compare to baseline"
