Install or update desloppify, then scan this codebase for code quality issues
(dead code, duplication, complexity, smells). It tracks findings persistently
across sessions and reports a health score.

Requires Python 3.11+. Install from PyPI:
  pip install --upgrade desloppify
  pip install --upgrade "desloppify[full]"
  desloppify update-skill codex

Use Devour wrappers (delegates to desloppify):
  devour quality scan --path .
  devour quality status
  devour quality next

Direct equivalent commands:
  desloppify scan --path .
  desloppify status
  desloppify next

--path is the directory to scan ("." for project root).
Language is auto-detected. To override:
  desloppify --lang python scan --path .
Note: --lang goes BEFORE the subcommand.

Fix findings, then resolve and rescan:
  desloppify resolve fixed <id> --note "what changed" --attest "I have actually [DESCRIBE THE CONCRETE CHANGE YOU MADE] and I am not gaming the score by resolving without fixing."

For false positives or intentional debt:
  desloppify resolve wontfix <id> --note "reason" --attest "I have actually verified this is intentional/false-positive and I am not gaming the score by resolving without fixing."

If subjective scores feel stale or inflated:
  desloppify scan --path . --reset-subjective

Run regularly (for example before each push). If desloppify itself looks wrong
or confusing, capture a repro and consider filing upstream:
  git clone https://github.com/peteromallet/desloppify.git /tmp/desloppify`
