guiding-refactoring-with-code-health

guiding-refactoring-with-code-health is a skill for Claude Code, Codex from DavidVujic/my-eca-config. It costs 28 tokens per session (460 once invoked), scanned A, original, MIT.

A refactoring guide that uses Code Health findings to improve difficult code in small steps. Refactoring means restructuring code without changing what it does, while Code Health provides maintainability findings and scores.

In plain words
What is it for?
Use it when files are hard to read, risky to modify, overly complex, too large, poorly organized, or repeatedly causing defects.
Why use it?
It replaces guesswork with a baseline and repeated checks, helping confirm that each structural change makes the code easier to work with.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

guiding-refactoring-with-code-health scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Guiding Refactoring With Code Health

Overview

Use Code Health as the control signal for refactoring. The agent should first understand why a file is hard to work with, establish a measurable baseline, then improve it in small structural steps and verify that each step helped. The goal is not just cleaner code, but code that is easier for both humans and agents to understand and modify safely.

When to Use

  • A file is hard to read, risky to change, or repeatedly attracts defects.
  • The user asks for refactoring help and wants an objective way to measure progress.
  • A safeguard or review points to complexity, size, low cohesion, or deep nesting.

Do not use this skill when the task is to rank project-wide priorities. Use prioritizing-technical-debt for that.

Quick Reference

  • code_health_review: Detailed maintainability findings for a file.
  • code_health_score: Numeric baseline and trend check across refactoring iterations.

Implementation

  1. Run code_health_review on the target file.
  2. Record the current code_health_score so the refactoring starts from a measurable baseline.
  3. Identify the highest-leverage structural problems, such as excessive responsibilities, deep nesting, low cohesion, or hard-to-follow control flow.
  4. Propose 3 to 5 small structural refactor steps, not a single rewrite.
  5. After each meaningful step, re-run code_health_review to see whether the targeted structural problems were reduced.
  6. Use code_health_score as the compact checkpoint to confirm directional improvement across iterations.
  7. Stop only when the targeted structural issues are substantially reduced and the score has measurably improved, or when the user explicitly accepts a partial uplift.

Common Mistakes

  • Refactoring without a baseline review.
  • Refactoring without recording the initial score.
  • Making a large rewrite that hides whether things improved.
  • Counting cosmetic cleanup as meaningful progress when the structural problems remain.
  • Using score checks alone without re-running the detailed review.
  • Forgetting to re-measure after each meaningful step.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
