sentrux-diff

name	sentrux-diff
description	Compare current sentrux metrics against the most recent baseline and report what got better or worse. Use when the user asks "did I break anything?", "diff quality since baseline", "what got worse?", or at the end of a refactor. Requires a prior `sentrux-baseline` or `session_start` call in the same MCP session.

Sentrux Diff

Runs a quality-delta check via the plugin:sentrux:sentrux MCP server.

Steps

1. Call mcp__plugin_sentrux_sentrux__session_end — this re-scans and diffs against the last baseline.
2. Report the delta:
   • Quality signal change — before → after with sign and magnitude
   • Degraded dimensions — list any that dropped more than 0.02, worst first
   • Improved dimensions — list any that rose more than 0.02 (briefly)
   • Top 3 files by complexity delta — if the MCP response includes file-level diffs

Guidance

• If the response indicates no baseline exists, tell the user and suggest /sentrux-baseline first.
• If nothing changed, say "No regression detected — quality signal unchanged at X.XX" in one line.
• Don't editorialize — small fluctuations (< 0.01) are noise and should be omitted.
• After reporting, if quality regressed, ask whether to run /sentrux-boundaries to see if a rule violation explains it.
